what i would do is wet the thing soaked it for a while then do the edges... also for texture a broom with fine bristles works wonders. you can also float the thing when the top is wet but the bottom is not dried yet. tapping the surface with a float will give bring up the more liquidy stuff and make a smooth surface (wich you can then broom then edge , with the edger dont put pressure too much otherwise it will make the peek you got and have to float it again.
Late for your project, but for future reference: Rebar ProTip - It would be better to have the reinforcing bar at the perimeter of the slab (even better if you can bend it to 90 degrees and have the reinforcing continuous at the corners).
This is what UA-cam needs. Someone who tackles a job and is not afraid to show the mistakes they made so others can learn from it. Probably learned more (planning to do this myself) from your videos than from the experts. Good job!
It can be a nightmare! If I don't know what I'm doing, I would hire a contractor and pay to get the job done professionally. I'm not the kind of person who think they know everything, and always right.
@@slimdude2011I wish you could just hire a contractor and it would be done with highest quality for a reasonable price. Good luck ... one reason many have resorted to doing it themselves is they pay full price, job the so called professionals do is as bad or worse than what they do themselves. Don't get me wrong, installing and finishing concrete us a skill. It's just hard to find someone willing to do small jobs at a reasonable price. Lastly, jobs you do yourself that come out well, you will get a good feeling every time you look at it.
This video is underrated. It's great to see how to do complex jobs correctly but it's also just as important to see the mistakes other people make. Thank you for making this video we can learn from.
We did a dry pour for a raised planter. Its difficult to get a good finish on dry powder and i think its more permeable than normal concrete. I wouldn't use it anywhere you can get a frost. I think getting a good finish can just be an afterthought. There are sand based skim coats that people use for decorative concrete that we could use to get a good finish, or even grinding and polishing or something like an acrilic paint like what is used on pool decks. Cracking is common with concrete slabs so control joints are used to give the cracks a place to form. I think the spacing standard in feet is 2.5x the the thickness in inches. So for a 4" slab its usually 10' max. For 1.5", it works out to 3' 9” max. There is also a standard for something long and skinny like a sidewalk, in which case i think the cuts need to be spaced no more than 1.5x the width. So for a 4' wide walk, the cuts should be spaced 6' or less apart. Personally, i wouldn't do concrete less than 3", even if its for just foot traffic.
The only people who never make mistakes are those who never do anything. It's part of the process, and now you know better for next time. Thanks for sharing your experience.
Dude, you and me are the same guy. I would have done it exactly like you, right down to "well I figured it would be ok". This is how real men do it, and it's just fine.
The reason for the pebble problem is not enough lateral (side to side) motion. You are pulling the screed forward instead of side to side. I just poured a large dry pour slab with much larger pebbles and it came out pretty smooth. You can also smooth it out with a long wooden float. I use a 3 footer and it works fine, especially in areas where my screed can't go. Hope this helps.
if the slab is 1 1/2” thick and your mix is using 1/2” aggregate then its only got room for 3 rocks to be on top of each other in the thickness of the slab! Ideally you want a little sand/ cement mix (cream) on top to cover the aggregate.
Why? there are innumerable way it can be done wrong - far more than you can ever come up with. Watching them will still not tell you how to make it work.
The one mistake I see everyone doing for a dry-pour or wet-pour is...not enough water after the initial setting-up of the concrete. The best way to harden a slab is to cover it in an inch of water for a month. The concrete actually grows a microscopic crystalline, dendritic interlocking web that grows outward in all directions like roots as it sets up but it needs water for this to occur. You might consider covering that slab with elastomeric paint with sand mixed in. That'll cover imperfections, give you a nice non-slip surface and will look great.
I considered painting the dry pour i did yesterday, but im worried it might seal the concrete and cause it not to keep adsorbing water from rain and cause it to not cure as strong.
Water is Integra to concrete hardening. You didn't use it anywhere near enough. Also you should have used the float again once you had it soaked and you would have found the surface would have leveled out nice and smoothly. Also, it should have been kept damp for at least a week at that dept, put damp hessian over it and keep re wetting.
I would even after a month or two after its had lots of time to cure. Pressure spray it let it dry and spend a $100 on a coat of Apoxy resin but add a tiny bit of silica sand to give it a bit of grip. You can make it any color you want aswell. And in the end that Apoxy will protect it from chipping flaking wear and tear and should hold everything together for years and years. Apoxy is Beautiful aswell. And the price has drastically come down lots over the past 10 years for such a strong product. Cheers and good luck. I'm looking forward to trying a dry pour myself one day.
I am a 72 year old woman and I did a dry pour "all by myself" it was 10 x 12 and turned out awesome. I also followed the instructions from Cajun Country. I wish I could send a picture.
YES MAM I LIKE YOUR GUMSHUN AND WILLINGNESS My wife and I are in our mid 70's and still building top to bottem 53 years of marrage and still enjoy each others help and friendship... when we got maried we ment it..
I am a widow, just shy of 72, and I’m getting ready to pour a 3 x 4 slab at the bottom of my steps. I am also digging out a bank and laying rocks steps with wet. My late husband and I poured a lot of wet mixed concrete at my previous home, and I am anxious to try this dry pour. I’m glad to hear yours turned out well.
That is excellent. I always love to see comments of a elder woman or man doing a diy like this.. Now I know I can do this myself and I'm only "59". I wish you could send pics on youtube as well, I would've loved to see it.
I'm about to do my first at 65yo - loving that all of us mature women are willing to give it a go - sisters doing it for themselves, to quote Annie Lennox and Aretha Franklin - but we did grow up through the first powerful wave of 70s feminism so it's no surprise.
You deserve a huge pat on the back. There are a lot of people, including myself, that have been too afraid to do anything for fear of failure, therefore not getting anything done. One thing I like about this video is that you are not acting like a know- it -all and you are telling it like it is and sharing your mistakes with others. To me, this is what these instructional videos are all about. Good luck in any future projects!
I really appreciate the honesty and sharing your mistakes. My husband and I love doing projects on our own. We spend a ton of time researching before jumping in! This is such a great help really showing "the good, the bad and the ugly"....that's the reality of DIY! It's not all easy, perfect, cheap. I applaud your candor and took note of the "tips" you provided. Oh....and it wasn't complete failure...its called personal growth,failure is not trying:) Thanks again!!
You are so welcome! Here is a video showing what I did to give this dry pour a better look. I agree, it's not a loss I learned a lot in the process and it's still functional. ua-cam.com/video/zjSK9tEIW6o/v-deo.html
Honestly , I like it. It's much better than mud. Right? And it looks good. I think you did a great job on a project that almost anyone would never attempt. So your 1st try is not perfect. I bet your next project will be much better. But, as I said this slab is fine for a shed. Congratulations! John in San Antonio
I appreciate how honest you were in the video, I think it looks like a great job. You could use a resurfacer OR get a bag of rapidset cement all and try to go over the areas where the Portland mix was used for a bit more strength but I think it looks good
Good thing is that that the Cajun Country Livin' channel show you how to dry pour a new slab on top of an old slab... you just have to follow all of their directions...
thanks for the video. Seeing what doesn't work is often just as helpful as seeing what does work. Thinking your calculator came up short on bags because most calculators assume you're mixing with water which increases the volume a bag will fill. Dry pour will always use more bags because you are packing the form at a higher density (considerably higher concrete to water ratio).
I love how dogs test out everything new in the house! thanks for all the information, I will try and do an interior dry pour to even out a sagging floor
I appreciate you having the courage to put your mistake out there to let others know what not to do. Another thing just my proven opinion, is I don't do a smooth finish on concrete. If I want to slip and be injured I go to an ice rink. I either finish with aggregate or broomed finish. Ty
I'm so glad you covered the mistake regarding adding the Portland mix sans aggregate to fill in the gaps as that is exactly something I would have done if faced with the same issue. Thanks for sharing!
If this was my DIY, I would have broken it up and started over. I would have been too ashamed to share my mistake with other DIY folks. And no one would have learned from my mistake. With that being said, I truly appreciate your honesty and willingness to let others learn from your mistakes. This was extremely helpful as I’m about to embark on my own dry pour. Wish me luck.
Seeing the goods and the bads of this process is great. Thank you for showing this even though it didn't turn out the way you wanted. I did a much smaller surface area for my first dry pour, but 4 inches deep (same number of bags of concrete as you needed), and had the same problem with the stone issue the first time I did it. It didn't matter what I did, I could not get it smooth. Without any research, I guess I lucked out and end ended up getting mortar mix instead of Portland (simply because I could get a small bag of mortar and couldn't get a small bag of Portland). That worked very well to make it smooth and the slab came out great. I'll also reinforce something that at least one other person said - use a lot of water....like more than recommended. I did three extra soakings and really soaked it the last 4 or 5 times. Realize that the Cajun folks live in Louisiana and I live in Wisconsin - both places where the soil is very wet most of the time and the concrete soaks water from the soil up into the concrete as you spray the top. It looks like you live somewhere it is dry, or at least the soil was very dry, and no water soaked up from the bottom. That is a huge benefit in this dry pour process. The compensation is using more water soakings...also I am absolutely no expert at all, but I think leave the forms on a lot longer than 24 hours. Everyone I have seen have edge problems with dry pour have taken off their forms the next day. I have now done several of these and have left the forms on for about a week (no reason other at first other than I didn't feel like taking them off, yet) and my edges are all good.
I think you are spot on and I'm confident my slab would have come out with a better appearance had I used mortar on the top. I do live in a high desert dry environment. I should have watered it more as you said. It's doing ok and I have decided to leave it "as is" to see what happens to it over a couple months or so. Depending on how that goes I'll decide what (if anything) to do about it then. I would go a little thicker if I were to do it again but I'm not convinced that you can't get a nice slab that's 1-1/2" thick if you have some experience with this process. Thanks for sharing your experience and information!
As for getting it smooth, going back and forth with the back side of a flat shovel seems to give a nice surface to work with before you pull it with a board. Seems to work the larger pieces into the cement while letting the smaller particles rise.
After watching several videos on this topic doing research for my upcoming pour, I could see the mistakes as they were made. But it's very useful to see those mistakes to confirm or disprove your theories before taking on a project. I have 80 bags, (4,800LBS) of concrete on the side of my house waiting for this to happen, and failure would be far too costly to have to demo/haul away/start over.
GOOD LUCK soak the ground 1st then rebar and wire mesh then spread dry concrete,, use a 6ft or 8 ft level as a screed,, start in the middle and work all around the perimeter
THANK YOU for sharing your mistakes! Usually posters hide errors and show perfect results and, when copied, it’s a disaster. How refreshing to watch a great video showing step by step with comments on errors so your viewers are spared making mistakes on their dry pours! You’re awesome!
I appreciate your honesty, not many people are willing to do that. As someone who doesn't have concrete experience either this is valuable content. I'll be looking forward to a follow up video and possibly a redo of the project.
One thing I found that helps with the pebbles is tapping after screadding, alout. Screadding brings the rock up, tapping brings the fluff cement up then use a paint roller and it looks great. Hope that helps.
Wow, your video is totally relatable. I watch inspirational DIY videos, and then attempt to do the same myself. First time it doesn't turn out as good as I hoped, but I still feel like I'm better off after because I learned so much from the process by doing it myself. It's ok because we're not pros, we're just bros.
Loved your video. You are hummble man who shows his mistakes from lack of knowledge and then shares it for our own benefit. It's such a hard and backbreaking job. The outcome was not what you were hoping but I am certain most viewers appreciate your honesty and will come to your rescue for the final perfection.
There are actually several concrete products that are made as an overlay that would make your slab look great. It’ll be an easy fix. Apply a concrete bonding agent 1st. 2nd, Mix the concrete overlay into a slurry and pour it onto your slab. I would recommend you put your forms around the perimeter again before doing the overlay. You could screed the overlay slurry mix and give it a broom finish after an hour or two.
Thank you for the info, I'm researching some of those solutions. When I decide what I'm going to do I'll post a video to share with you. I appreciate the tip!
@@DIYHomesteadProjectsDIYHP10 What Rene said is extremely doable. We used to fix scoured out spillways on dams like that. After a thorough pressure washing, we applied a bonding agent. Add some bonding agent+water to a feathering concrete mix. BRUSH some of the mix well into the bonding treated area (important not to just smear it on with a trowel). THEN you can trowel on and finish your feathering treatment. Sets and bonds hard enough to withstand water erosion on a concrete dam.
I think it turned out great! Rarely does anyone’s first time doing something turn out how we envision. One of the best outcomes is the ability to learn. I call this a win!! Good job and I’m hoping my attempt comes out half as good as yours!
@@DIYHomesteadProjectsDIYHP10 Great job and video. Try and learn about the work and yourself. I did however once hear the caveat, if at first you don't succeed, skydiving is not for you. ;-)
"patting" then troweling the concrete surface with a finishing trowel after wetting will embed the aggregate and leave a smooth surface, let it set for 20-30 minutes, then lightly drag a push broom over it for a brushed, non-skid finish (then use your edging tool for a smooth border). don't forget to have your family put their initials and handprints in a corner.
The thing people need to learn before doing a dry pour is that a lot of people online don't know the difference between Concrete, Mortar and Cement and they make videos not realizing they are calling Cement Concrete or Mortar Concrete or they just think they are all the same thing and call them all Concrete. Those other videos here on UA-cam where they get a smooth dry pour might be using Concrete (which has gravel) as a base underneath but then they use Cement (just powder) or Mortar (powder and sand mix) on top to help keep it smooth on top and free from gravel. Cement is the powder with nothing mixed in. Mortar is a mix of Cement and Sand (used for brick laying etc). Concrete is a mix of Cement, Gravel/Rock to provide strength and then sometimes Fibers mixed in for even more strength. The point is, they likely use Cement or Mortar on top to make the top smooth... or they used just Cement or Mortar by itself, which would be the wrong way to dry pour an entire slab.
i found out if you dry pour the slab and left a few mm of space at the top you can come back and wet-pour some Rapid set mortar mix and finish it off the traditional way, wet. You get a better fit and finish. If that is the look you are looking for. So the dry pout method to build up and the mortar mix to finish. I do the mortar mix before I pull the boards off after a couple days of letting the dry pour cure. The Rapid Set doesn't need a bonding agent and the new dry pour isn't dirty so you can just go right over it. Just remember to wet the top before you pour the mortar mix.
I enjoyed your video. You made an honest attempt at a new idea. I just poured a 3×2 step and followed the manufacturers directions for the amount of water to add. My surface looks very similar to yours. I added 3.5 quarts per bag just like they said to. It has a rough surface because I didn't have amy cream on top to finish the top. I tried to do it the manufacturers way and you came up with your own way. I'm pretty sure the concrete guys that do this for a living have way wetter concrete to get those smooth finishes. Next time, I'm going to mix my dry concrete bags with a shovel load of portland cement and a swivel of sand.
Your video made me chuckle several times as I had almost all the same battles while trying my first dry pour a few weeks ago. Fingers crossed yours holds up.
Thanks so much for this video. I too had never done a dry pour before. I felt like such a loser as the top was pocked throughout and looked like the surface of the moon. After a couple of weeks I got the idea of adding a layer of fine mortar. I added shovelfuls at a time and gently brushed with a wide broom. It was a big improvement. I lightly misted it and only time will tell if that was successful. It’s far from perfect but I can live with it.
Sorry you had to learn so many lessons the hard way, but you have helped enlighten the rest of us with your video and tips on how to avoid problems. So thanks for that. On the bright side, your 15 year old buddy appreciated your hard work! Good job!
The most helpful thing (to me) in your video is your honesty. I'm nit very handy, I also watched the Cajun concrete folks and thought well, that doesn't look so hard! Listening to you, I pictured how exhausted I'd be simply trying to carry bags in to my yard from the car. I think I'll go back to the idea if pavers. This is a task I'm just not ready for. Financially, physically...but I thank you so much for the info!!!
Pretty much the reason you had the tough time with the pebbles is because you didn’t have enough concrete. When you are short on the amount, it don’t have enough powder to cover the voids. If you go back and look at the video, you will notice that the area where you ran out of bags it will show the most rock. It happens the same way with wet pours.
I forgot to mention… you don’t want to put a layer of a different product over cement, it won’t ever come out well. It is just better to have way too much cement and bring the extra back.
on wet concrete usually you get a mag bull float / fresno to push aggregate down and bring up what they call the cream that why results will be diffrent dry pouring is not the way to go for slabs or foundations , now it might work if you were to premix in portland cement and then put it down or screen out the aggregate maybe add sand you might get a smoother dry pour but now it's just mortar at that point.
Thank you for sharing your mistakes. I am planning on pouring a slab soon, and wanted to try the dry pour method. After watching your video, I decided to do the traditional wet pour to avoid the pebbles on the surface. Great video man! I learned from your mistakes.
Yes, these are great tips, and no one on these videos ever mention to use mortar for your final layer. I did the same thing. Poured concrete mix, screed and screed and screed and screed and screed lol and finally quit. It then rained after my first 3 waterings and left divots, mostly from not being able to screed all the rocks down. But if I would’ve known about the mortar portion, mine probably would’ve came out better too, but thanks for this great video and tips. 👍
I’m considering trying a recap of some sort on my slab. It’s all an experiment so I have no idea how it will turn out. If I do it I’ll post a video showing what I did good or bad then you can decide if it might work for you. Thanks for watching and posting your comment!
I have seen the Cajun videos and loved them, and always wondered if it really works. After watching your video, it has helped me to decide to try the dry technique. Thank you for sharing your mistakes.
Thanks for the honesty! I just ordered 50 90lbs bags of Quikrete to try to make my first concrete project... A 40' X 5' slab to fill in the walk way on the side of the house. I'm planning to make it in ~2.5' x 2' stone sections. Sprinkling pure cement on top to make the surface smooth did come to mind! Thanks for getting that out of my head! Would have never lived it down from my brother (contractor) who's trying to talk me out of doing a dry pour in the first place.
Interesting video. For most codes, foottraffic-only slab on ground requires a minimum thickness of 89 mm (3.5 inches)@3000 psi compressive strength. If you use rebar, at least 40 mm (1.6 inches) concrete cover is required over the rebar. If you use straight portland, you have to account for the chemical reaction ratio: 1/7. So you need six to seven times the amount of water during curing. 48 hours minimum before form removal or any weight set on surface. IMO regardless the thickness, the commercial standard of seven days curing (covered with tarp or film, 2xdaily mist until pooled) would be the way to go. If you really want a thin slab, consider ferrocement as an alternative.
This may be doubling up but I want this response brought to the attention of you bothe: Even for DIY's some cities require permits, project inspected, and an inspector on site.
Thanks for sharing. In others video, they keep mentioning more concrete to get the smooth surface. Motar top layer may look good on the surface literally but I think the durability is not there. Just something to consider beforehand.
Thank you for the video. I did a dry pour based on the Cajun Country video having never done concrete before. There are probably some steps off camera that made the results better. However using just Portland doesn't seem to be a good idea since it lacks a binding component.
Interesting. Well, it was a good learning experience, next time things will certainly be easier. Hopefully since you only expect foot traffic it will hold up....fingers crossed. Thanks for posting this despite not achieving the results you had desired as it's really helpful for learning !
Thanks Joe, hopefully it will help someone else if they decide to try one of these "dry pour concrete slabs". I'm looking into some possible "fix it" solutions that I may try in the future. Honestly I think it's going to serve it's purpose as is but we'll see how it performs over time.
Thanks for sharing. Ran into the same problem with a rough surface and pebbles on top just a couple days ago. One tip i found is to strain the larger pebbles out from some of your concrete and use that to fill in the low spots. Gets you a mix that plays well with the rest of the concrete and you don't have to buy 2 mixes, which is nice for smaller projects.
Also the cracks is because you have to keep wetting it for the next few days. Get a longer screed next time. You need at least a foot ad a half hangung on either side of your form. That will give you the space for lateral screeding as opposed to only 4 inches of lateral movement as I can tell from your video.
I'm considering doing something similar to this at the bottom of my new deck steps. I was thinking it would need to be 3 or 4 inches thick as well. Or i may go with 12 inch pavers. Thanks for the video
I did a 2 by 4 foot, but thicker (about 3") and had the same experience. That was also with Sakrete High Strength. I screeded many passes and the surface got slightly better but never good. I had half a bag extra at my disposal so it wasn't due to lack of product. I'm reading that others say that Quikrete might have less rocks, and since my pour is so small I might start over and try that for comparison. Thank you for the video, it's very informational.
This morning I did a dry pour over an existing small slab to extend it. I had some sakcrete laying around so I used that as the base and then topped it with quikcrete. In my opinion quikcrete has a finer powder finish than the other brand. I also finished it like it were a wet pour, I used a trowel and an edger to get a smooth finish and then put texture on it. I've never done any concrete work before, so I thought I'd start with this process vs the wet application. I did a 4 inch thick slab so there's another an inch on top of the existing 3 inch slab. I'll do the 8th soak in an hour. Hoping this works because I have lots of projects! Appreciate your video here .
you need to stick the second slab onto the existing slab, it's called keying in. It won't just bond together without a bonding agent, even water, neat cement powder, and broom into a slurry, then the 2 slabs will bond together.
Aww, bummer that you had such a rough time, but thanks so much for sharing your project. I've been watching all the dry pours since Cajun Country Livin's, and I think this one is the first I've seen that shows things that could go wrong. I also really appreciate the tips in the comments for how to remedy it. I'm looking at my own projects soon. We're all in this together!
As a retired pool builder I highly recommend NOT doing dry pour. It’s not really easier or quicker and it’s just stupid to think that you can dump out a bag and everything will be thoroughly mixed together for uniform strength. Here is response from quickrete after I emailed them about this nonsense Thank you for reaching out to us! We are aware of at least one video on-line, published by a source other than QUIKRETE®, which demonstrates QUIKRETE Concrete Mix being used in a manner inconsistent with our directions which will lead to a degradation in quality of the final product. Additionally, failure to follow package directions voids the product warranty. While we understand the desire to develop other methods that may seem to make use of our product easier or faster, our directions are developed after extensive testing to generate the highest quality results possible. In the video, QUIKRETE® Concrete Mix is poured dry for a small slab, then misted multiple times with water after the dry material has been placed. No QUIKRETE® concrete product is intended to be used for slabs without blending it with clean water prior to placing. Again, thank you for contacting us and do not hesitate to reach out with additional questions!
@@DIYHomesteadProjectsDIYHP10 next time you see a concrete worker eating lunch or at the hardware store or if you see them at a job site. Ask them. Funny all these people that don’t know squat about concrete would rather take there advise from a couple in their backyard than concrete workers. Many have chimed in, and not one has said it’s a good idea. But hey, I understand you’ve made up your mind and don’t want to be confused by facts Good luck with your projects
I really appreciated this video. I had seen the dry pour videos before I poured a slab for an AC condensing unit behind my garage. I went ahead and mixed my concrete in a wheel barrow and dumped in place. While I had to mix 6 bags by hand, it wasn't terrible and after I worked the concrete a bit, it came out very nice. I'm not sure I would do a dry pour simply due to all the issues you had.
For all the 'problems' you ran into, the final result is still good. I'd recommend using 2x4's instead of going for the 1.5 inch thickness for beginners, then working your way up into thinner projects. For a given size of the project, thickness becomes your margin of error. Over water and allow for days for this to set up before giving it any load. Also buy a few more bags than you think you'll need. After the initial screed boarding you'll see rocks and that means add more concrete. I like to add it by the large scoop once it looks like you're close so you can minimize over spill, but if you're not worried about ten bucks of concrete just overfill from the start and shop vac it up.
Looks pretty good for a first slab pour. The portland probably needs a lot longer cure time than you gave it as well, but obviously mortar would have been the better call.
I finish concrete for a living so this peaked my interest. This is a very cool little hack, depending on what you are using it for. Air conditioner pad, kennel, etc. Please do not do this anywhere other than your own home. You will certainly be getting sued or at the very least called back to replace it after 1 winter. Especially at 1.5 inches. That may work for a countertop, but not anything exposed to any kind of temp change. Thanks for sharing this with us. You learned something valuable no matter what.
I subscribed. Your video is a rare gem and offers a lot of real world insight and experience to ambitious first time diy'ers such as myself. Thank you so much for taking the time make, edit, and upload this video!
Thank you for sharing your experience. Right before you went to use the portland cement as a filler I was thinking the same thing as you. Glad I watched this! I would have made the same decision. My first dry pour will be a much smaller pad, a 3' by 4', to access a hose bib that I have to walk through mud to get to. I am planning about 3" thick.
Thanks for being so honest in your mistakes. Dry mix is really only useful for post holes. 4 inches thick is really a minimum, wet mix is the only secure way for a job like this.
I find these types of videos way more interesting and informative than others where all jobs come out almost perfect because of the magic of editing. I appreciate your honesty and wish you the best in your next project!
I can appreciate the share. You tried it and that counts. And as others have said, it can be improved without needing replacement, if you decide to do an overlay!
You're right, I'm researching many options for an overlay. I haven't decided yet if I even need to do one. It really isn't all that bad but just not as good as I hoped. Thanks for your input.
I think it'll be fine. We used to broadcast cement on top of concrete slab to give it a smooth surface after it was pour. Great job! I've also watch them pour dry concrete to
That doesn't just give it a smooth finish. If you continue to add cement and trowel it in hard, it will create an amazingly hard surface. This is usually done on large slabs. The next time you go into one of the big box stores look closely at the finish on the floor. If it's very smooth concrete with a shine, it's been done by lightly broadcasting pure cement over the floor during the time they are hard troweling with one of those big power trowels. The result is akin to using Gunite on a pool. The surface is impregnated between the surface sand with cement, resulting in a surface that is almost indestructible
I did a 30" x 38' dry pour on the side of my garage for a step and had a few of the same issues you had with the pebbles showing but overall I'm happy. It was super simple to do and its rock solid. I did water it for a week and kept a tarp over it to retain moisture. Its been a few months now and it looks exactly like it did when I "poured" it.
I read ya but I love the idea of dry pour simply because for my 66 year-old back it's far less physically stressful than mixing the wet stuff, and I am sick of labourers here botching everything they touch. I could fill a few sides of A4 with horror stories from when I had my house extended upwards a year ago. I'm in the Philippines and the lads here simply cannot get apprenticeships for trades like bricklaying, carpentry, plumbing, electrical, plastering etc - these kids leave school with no qualifications and many get a job working for a friend or relative and learn as they go along, usually from YT. I caught one of 'em trying to run a socket cable diagonally along and up the wall to the ceiling exit point - he'd actually chased out the plaster! That whole extension episode finished me with using local labour for important jobs. I've got 2 slabs to lay for small sheds and I will do it myself - dry!
Thank you for this. This video is more helpful to me than any of the other perfectly done dry-pours. I was more likely to make the mistakes you made than get it right the first time. Good on you for being able to show your mistakes so many of us can avoid some of these mistakes. Thanks again.
Thanks for sharing the ups and downs of your project. I would have tried the Portland cement too without your advice. I might have tried to trowel the surface when it was wet to bring up the crème, but still have the sand and gravel mixer to hold it together.
fantastic video. Coming from someone who has never poured concrete, I learned a lot of what not to do and why not to do it. My initial logic on using cement would have been the same as yours. So thanks for saving me the disappointment.
See how I power my off grid workshop - ua-cam.com/video/CwL5dWB3kOQ/v-deo.html
And thanks for this!
You're welcome, thanks for watching.
what i would do is wet the thing soaked it for a while then do the edges... also for texture a broom with fine bristles works wonders. you can also float the thing when the top is wet but the bottom is not dried yet. tapping the surface with a float will give bring up the more liquidy stuff and make a smooth surface (wich you can then broom then edge , with the edger dont put pressure too much otherwise it will make the peek you got and have to float it again.
Late for your project, but for future reference:
Rebar ProTip - It would be better to have the reinforcing bar at the perimeter of the slab (even better if you can bend it to 90 degrees and have the reinforcing continuous at the corners).
Qwikcrete
This is what UA-cam needs. Someone who tackles a job and is not afraid to show the mistakes they made so others can learn from it. Probably learned more (planning to do this myself) from your videos than from the experts. Good job!
I wish you the best with your project!
It can be a nightmare! If I don't know what I'm doing, I would hire a contractor and pay to get the job done professionally. I'm not the kind of person who think they know everything, and always right.
I know the feeling when say O Sxxx what did I do. But at least you gave it a good effort. How much weight did it hold?
@@slimdude2011I wish you could just hire a contractor and it would be done with highest quality for a reasonable price. Good luck ... one reason many have resorted to doing it themselves is they pay full price, job the so called professionals do is as bad or worse than what they do themselves.
Don't get me wrong, installing and finishing concrete us a skill. It's just hard to find someone willing to do small jobs at a reasonable price.
Lastly, jobs you do yourself that come out well, you will get a good feeling every time you look at it.
1000%, THIS is why the internet was created. That, and hot moms that live 6 miles from me.
Thanks for the video. As my old man used to say, "Any dumbass can learn from their own mistakes, a smart man learns from someone else's!"
This video is underrated. It's great to see how to do complex jobs correctly but it's also just as important to see the mistakes other people make. Thank you for making this video we can learn from.
I appreciate that and thanks for stopping by.
I love how honest you are about your learning curve. Most channels make everything look so easy, but you know they edited out some mistakes.
If I can learn from my mistakes why not let others learn from them too.
We did a dry pour for a raised planter. Its difficult to get a good finish on dry powder and i think its more permeable than normal concrete. I wouldn't use it anywhere you can get a frost. I think getting a good finish can just be an afterthought. There are sand based skim coats that people use for decorative concrete that we could use to get a good finish, or even grinding and polishing or something like an acrilic paint like what is used on pool decks. Cracking is common with concrete slabs so control joints are used to give the cracks a place to form. I think the spacing standard in feet is 2.5x the the thickness in inches. So for a 4" slab its usually 10' max. For 1.5", it works out to 3' 9” max. There is also a standard for something long and skinny like a sidewalk, in which case i think the cuts need to be spaced no more than 1.5x the width. So for a 4' wide walk, the cuts should be spaced 6' or less apart. Personally, i wouldn't do concrete less than 3", even if its for just foot traffic.
Large areas of concrete are usually cut with a saw for a control joint
Thank you for showing us the mistakes that were made rather than trying to hide them.
The only people who never make mistakes are those who never do anything. It's part of the process, and now you know better for next time. Thanks for sharing your experience.
Yes! Thank you!
Dude, you and me are the same guy. I would have done it exactly like you, right down to "well I figured it would be ok". This is how real men do it, and it's just fine.
You know what they say, great minds think alike. LOL 👍
@DIYHomesteadProjectsDIYHP10 Right after you said it had too many pebbles, I thought "He should add some cement to the top". 😂
The reason for the pebble problem is not enough lateral (side to side) motion. You are pulling the screed forward instead of side to side. I just poured a large dry pour slab with much larger pebbles and it came out pretty smooth. You can also smooth it out with a long wooden float. I use a 3 footer and it works fine, especially in areas where my screed can't go. Hope this helps.
Thank you for the nice tips they help alot!
Wow, lightbulb!
Thank you for this important tidbit of info!
Also the 1 1/2" thick slab makes it a little more difficult.
@@JamesArvidsonHow so?
I'm curious how the thickness affects being able to smooth the top...
if the slab is 1 1/2” thick and your mix is using 1/2” aggregate then its only got room for 3 rocks to be on top of each other in the thickness of the slab! Ideally you want a little sand/ cement mix (cream) on top to cover the aggregate.
Thank you for showing us your trial and error. Appreciate your effort in trying to keep others from making the same mistakes.
DIY Homestead Projects certainly is a community these days! I found the video to be extremely worthwhile. Thanks for sharing it!
Thanks for watching!
Great job admitting an error and helping others that are trying to tackle the same thing.
Thank you and thanks for stopping by.
UA-cam/internet needs more videos like this, that tells you what Not to do. Far more useful than videos where everything goes perfect the first time.
Why? there are innumerable way it can be done wrong - far more than you can ever come up with. Watching them will still not tell you how to make it work.
The one mistake I see everyone doing for a dry-pour or wet-pour is...not enough water after the initial setting-up of the concrete. The best way to harden a slab is to cover it in an inch of water for a month. The concrete actually grows a microscopic crystalline, dendritic interlocking web that grows outward in all directions like roots as it sets up but it needs water for this to occur. You might consider covering that slab with elastomeric paint with sand mixed in. That'll cover imperfections, give you a nice non-slip surface and will look great.
That is definitely a consideration. Thanks for the info and tip!
I considered painting the dry pour i did yesterday, but im worried it might seal the concrete and cause it not to keep adsorbing water from rain and cause it to not cure as strong.
Water is Integra to concrete hardening. You didn't use it anywhere near enough. Also you should have used the float again once you had it soaked and you would have found the surface would have leveled out nice and smoothly. Also, it should have been kept damp for at least a week at that dept, put damp hessian over it and keep re wetting.
I would even after a month or two after its had lots of time to cure. Pressure spray it let it dry and spend a $100 on a coat of Apoxy resin but add a tiny bit of silica sand to give it a bit of grip. You can make it any color you want aswell. And in the end that Apoxy will protect it from chipping flaking wear and tear and should hold everything together for years and years. Apoxy is Beautiful aswell. And the price has drastically come down lots over the past 10 years for such a strong product. Cheers and good luck. I'm looking forward to trying a dry pour myself one day.
what you mean The best way to harden a slab is to cover it in an inch of water for a month ? how i cover with water ? just spray every 1h ?
I give you a 10 for not giving up.
👋🤠👍
I am a 72 year old woman and I did a dry pour "all by myself" it was 10 x 12 and turned out awesome. I also followed the instructions from Cajun Country. I wish I could send a picture.
Excellent!
YES MAM I LIKE YOUR GUMSHUN AND WILLINGNESS My wife and I are in our mid 70's and still building top to bottem 53 years of marrage and still enjoy each others help and friendship... when we got maried we ment it..
I am a widow, just shy of 72, and I’m getting ready to pour a 3 x 4 slab at the bottom of my steps. I am also digging out a bank and laying rocks steps with wet. My late husband and I poured a lot of wet mixed concrete at my previous home, and I am anxious to try this dry pour. I’m glad to hear yours turned out well.
That is excellent. I always love to see comments of a elder woman or man doing a diy like this.. Now I know I can do this myself and I'm only "59". I wish you could send pics on youtube as well, I would've loved to see it.
I'm about to do my first at 65yo - loving that all of us mature women are willing to give it a go - sisters doing it for themselves, to quote Annie Lennox and Aretha Franklin - but we did grow up through the first powerful wave of 70s feminism so it's no surprise.
You deserve a huge pat on the back. There are a lot of people, including myself, that have been too afraid to do anything for fear of failure, therefore not getting anything done.
One thing I like about this video is that you are not acting like a know- it -all and you are telling it like it is and sharing your mistakes with others. To me, this is what these instructional videos are all about. Good luck in any future projects!
Thanks for stopping by!
I really appreciate the honesty and sharing your mistakes. My husband and I love doing projects on our own. We spend a ton of time researching before jumping in! This is such a great help really showing "the good, the bad and the ugly"....that's the reality of DIY! It's not all easy, perfect, cheap. I applaud your candor and took note of the "tips" you provided. Oh....and it wasn't complete failure...its called personal growth,failure is not trying:) Thanks again!!
You are so welcome! Here is a video showing what I did to give this dry pour a better look. I agree, it's not a loss I learned a lot in the process and it's still functional. ua-cam.com/video/zjSK9tEIW6o/v-deo.html
Absolutely. Well said!!!!!!!!!!!!!!!!!!!!!! Others can learn from you so I can really appreciate it.
Honestly , I like it. It's much better than mud. Right? And it looks good. I think you did a great job on a project that almost anyone would never attempt. So your 1st try is not perfect. I bet your next project will be much better. But, as I said this slab is fine for a shed.
Congratulations!
John in San Antonio
Thank you!
Thank you!
I appreciate how honest you were in the video, I think it looks like a great job. You could use a resurfacer OR get a bag of rapidset cement all and try to go over the areas where the Portland mix was used for a bit more strength but I think it looks good
Thank you and I appreciate the tips!
Michael Builds channel did use Cement All to patch up some areas and it looked good.
Good thing is that that the Cajun Country Livin' channel show you how to dry pour a new slab on top of an old slab... you just have to follow all of their directions...
thanks for the video. Seeing what doesn't work is often just as helpful as seeing what does work. Thinking your calculator came up short on bags because most calculators assume you're mixing with water which increases the volume a bag will fill. Dry pour will always use more bags because you are packing the form at a higher density (considerably higher concrete to water ratio).
That makes perfectly good sense. Thanks for the info, I appreciate it!
I love how dogs test out everything new in the house!
thanks for all the information, I will try and do an interior dry pour to even out a sagging floor
I appreciate you having the courage to put your mistake out there to let others know what not to do.
Another thing just my proven opinion, is I don't do a smooth finish on concrete. If I want to slip and be injured I go to an ice rink. I either finish with aggregate or broomed finish. Ty
I'm so glad you covered the mistake regarding adding the Portland mix sans aggregate to fill in the gaps as that is exactly something I would have done if faced with the same issue. Thanks for sharing!
Glad it was helpful!
Most importan: your wife is with you helping in this project...❤
I agree, I'm a lucky man! 👍
I mean you did it. A lot of people don't try since they don't want to fail. You live and learn. Thanks for sharing your mistakes!
Exactly!
If this was my DIY, I would have broken it up and started over. I would have been too ashamed to share my mistake with other DIY folks. And no one would have learned from my mistake. With that being said, I truly appreciate your honesty and willingness to let others learn from your mistakes. This was extremely helpful as I’m about to embark on my own dry pour. Wish me luck.
I wish you good luck with your project!
how didn your dry poor go buddy? hopefully better then this guys
Seeing the goods and the bads of this process is great. Thank you for showing this even though it didn't turn out the way you wanted. I did a much smaller surface area for my first dry pour, but 4 inches deep (same number of bags of concrete as you needed), and had the same problem with the stone issue the first time I did it. It didn't matter what I did, I could not get it smooth. Without any research, I guess I lucked out and end ended up getting mortar mix instead of Portland (simply because I could get a small bag of mortar and couldn't get a small bag of Portland). That worked very well to make it smooth and the slab came out great. I'll also reinforce something that at least one other person said - use a lot of water....like more than recommended. I did three extra soakings and really soaked it the last 4 or 5 times. Realize that the Cajun folks live in Louisiana and I live in Wisconsin - both places where the soil is very wet most of the time and the concrete soaks water from the soil up into the concrete as you spray the top. It looks like you live somewhere it is dry, or at least the soil was very dry, and no water soaked up from the bottom. That is a huge benefit in this dry pour process. The compensation is using more water soakings...also I am absolutely no expert at all, but I think leave the forms on a lot longer than 24 hours. Everyone I have seen have edge problems with dry pour have taken off their forms the next day. I have now done several of these and have left the forms on for about a week (no reason other at first other than I didn't feel like taking them off, yet) and my edges are all good.
I think you are spot on and I'm confident my slab would have come out with a better appearance had I used mortar on the top. I do live in a high desert dry environment. I should have watered it more as you said. It's doing ok and I have decided to leave it "as is" to see what happens to it over a couple months or so. Depending on how that goes I'll decide what (if anything) to do about it then. I would go a little thicker if I were to do it again but I'm not convinced that you can't get a nice slab that's 1-1/2" thick if you have some experience with this process. Thanks for sharing your experience and information!
As for getting it smooth, going back and forth with the back side of a flat shovel seems to give a nice surface to work with before you pull it with a board. Seems to work the larger pieces into the cement while letting the smaller particles rise.
After watching several videos on this topic doing research for my upcoming pour, I could see the mistakes as they were made. But it's very useful to see those mistakes to confirm or disprove your theories before taking on a project. I have 80 bags, (4,800LBS) of concrete on the side of my house waiting for this to happen, and failure would be far too costly to have to demo/haul away/start over.
Get a professional cement finishers. Save your back a ass whiping and your time. Believe me my friends.
GOOD LUCK
soak the ground 1st
then rebar and wire mesh
then spread dry concrete,, use a 6ft or 8 ft level as a screed,, start in the middle and work all around the perimeter
THANK YOU for sharing your mistakes! Usually posters hide errors and show perfect results and, when copied, it’s a disaster. How refreshing to watch a great video showing step by step with comments on errors so your viewers are spared making mistakes on their dry pours! You’re awesome!
Thanks for stopping by!
I appreciate your honesty, not many people are willing to do that.
As someone who doesn't have concrete experience either this is valuable content.
I'll be looking forward to a follow up video and possibly a redo of the project.
One thing I found that helps with the pebbles is tapping after screadding, alout. Screadding brings the rock up, tapping brings the fluff cement up then use a paint roller and it looks great. Hope that helps.
Thanks for the tips!
I hope this isn't too crude but I thought about using a vibrator. Then I realized that might not have enough kick so a back massager might do better.
Wow, your video is totally relatable. I watch inspirational DIY videos, and then attempt to do the same myself. First time it doesn't turn out as good as I hoped, but I still feel like I'm better off after because I learned so much from the process by doing it myself. It's ok because we're not pros, we're just bros.
Loved your video. You are hummble man who shows his mistakes from lack of knowledge and then shares it for our own benefit. It's such a hard and backbreaking job. The outcome was not what you were hoping but I am certain most viewers appreciate your honesty and will come to your rescue for the final perfection.
Thanks for stopping by!
There are actually several concrete products that are made as an overlay that would make your slab look great. It’ll be an easy fix. Apply a concrete bonding agent 1st. 2nd, Mix the concrete overlay into a slurry and pour it onto your slab. I would recommend you put your forms around the perimeter again before doing the overlay. You could screed the overlay slurry mix and give it a broom finish after an hour or two.
Thank you for the info, I'm researching some of those solutions. When I decide what I'm going to do I'll post a video to share with you. I appreciate the tip!
@@DIYHomesteadProjectsDIYHP10 What Rene said is extremely doable. We used to fix scoured out spillways on dams like that. After a thorough pressure washing, we applied a bonding agent. Add some bonding agent+water to a feathering concrete mix. BRUSH some of the mix well into the bonding treated area (important not to just smear it on with a trowel). THEN you can trowel on and finish your feathering treatment. Sets and bonds hard enough to withstand water erosion on a concrete dam.
Excellent, thanks for the info!
I think it turned out great! Rarely does anyone’s first time doing something turn out how we envision. One of the best outcomes is the ability to learn. I call this a win!! Good job and I’m hoping my attempt comes out half as good as yours!
Thank you! I wish you the best with your project!
@@DIYHomesteadProjectsDIYHP10 Great job and video. Try and learn about the work and yourself.
I did however once hear the caveat, if at first you don't succeed, skydiving is not for you. ;-)
it is an outdoor entry slab. who care about the pebbles etc. great job
"patting" then troweling the concrete surface with a finishing trowel after wetting will embed the aggregate and leave a smooth surface, let it set for 20-30 minutes, then lightly drag a push broom over it for a brushed, non-skid finish (then use your edging tool for a smooth border). don't forget to have your family put their initials and handprints in a corner.
This video is fantastic. Thank you for showing your mistakes to teach us, i find it even more helpful sometimes.
Glad it was helpful!
The thing people need to learn before doing a dry pour is that a lot of people online don't know the difference between Concrete, Mortar and Cement and they make videos not realizing they are calling Cement Concrete or Mortar Concrete or they just think they are all the same thing and call them all Concrete. Those other videos here on UA-cam where they get a smooth dry pour might be using Concrete (which has gravel) as a base underneath but then they use Cement (just powder) or Mortar (powder and sand mix) on top to help keep it smooth on top and free from gravel.
Cement is the powder with nothing mixed in.
Mortar is a mix of Cement and Sand (used for brick laying etc).
Concrete is a mix of Cement, Gravel/Rock to provide strength and then sometimes Fibers mixed in for even more strength.
The point is, they likely use Cement or Mortar on top to make the top smooth... or they used just Cement or Mortar by itself, which would be the wrong way to dry pour an entire slab.
Absolute legend .. actually showed the real time information working as a DIYer .. thanks
Glad it helped
i found out if you dry pour the slab and left a few mm of space at the top you can come back and wet-pour some Rapid set mortar mix and finish it off the traditional way, wet. You get a better fit and finish. If that is the look you are looking for. So the dry pout method to build up and the mortar mix to finish. I do the mortar mix before I pull the boards off after a couple days of letting the dry pour cure. The Rapid Set doesn't need a bonding agent and the new dry pour isn't dirty so you can just go right over it. Just remember to wet the top before you pour the
mortar mix.
Thanks for the good information! I may give that a try. It makes perfectly good sense to me.
I enjoyed your video. You made an honest attempt at a new idea. I just poured a 3×2 step and followed the manufacturers directions for the amount of water to add. My surface looks very similar to yours. I added 3.5 quarts per bag just like they said to. It has a rough surface because I didn't have amy cream on top to finish the top. I tried to do it the manufacturers way and you came up with your own way. I'm pretty sure the concrete guys that do this for a living have way wetter concrete to get those smooth finishes. Next time, I'm going to mix my dry concrete bags with a shovel load of portland cement and a swivel of sand.
UA-cam videos always make it look easy.
Your video made me chuckle several times as I had almost all the same battles while trying my first dry pour a few weeks ago. Fingers crossed yours holds up.
Good stuff!
Thanks so much for this video. I too had never done a dry pour before. I felt like such a loser as the top was pocked throughout and looked like the surface of the moon. After a couple of weeks I got the idea of adding a layer of fine mortar. I added shovelfuls at a time and gently brushed with a wide broom. It was a big improvement. I lightly misted it and only time will tell if that was successful. It’s far from perfect but I can live with it.
It sucks when you work so hard and it still doesn’t come out the way it should. Thanks for sharing your learning experience.
Sorry you had to learn so many lessons the hard way, but you have helped enlighten the rest of us with your video and tips on how to avoid problems. So thanks for that. On the bright side, your 15 year old buddy appreciated your hard work! Good job!
Glad it was helpful!
The most helpful thing (to me) in your video is your honesty. I'm nit very handy, I also watched the Cajun concrete folks and thought well, that doesn't look so hard! Listening to you, I pictured how exhausted I'd be simply trying to carry bags in to my yard from the car. I think I'll go back to the idea if pavers. This is a task I'm just not ready for. Financially, physically...but I thank you so much for the info!!!
I wish you the best.
Pretty much the reason you had the tough time with the pebbles is because you didn’t have enough concrete. When you are short on the amount, it don’t have enough powder to cover the voids. If you go back and look at the video, you will notice that the area where you ran out of bags it will show the most rock. It happens the same way with wet pours.
That's some good info and I think you may be right about that.
I forgot to mention… you don’t want to put a layer of a different product over cement, it won’t ever come out well. It is just better to have way too much cement and bring the extra back.
Good to know and thanks for the info!
Yep
on wet concrete usually you get a mag bull float / fresno to push aggregate down and bring up what they call the cream that why results will be diffrent dry pouring is not the way to go for slabs or foundations , now it might work if you were to premix in portland cement and then put it down or screen out the aggregate maybe add sand you might get a smoother dry pour but now it's just mortar at that point.
Thank you for sharing your mistakes. I am planning on pouring a slab soon, and wanted to try the dry pour method. After watching your video, I decided to do the traditional wet pour to avoid the pebbles on the surface. Great video man! I learned from your mistakes.
Glad it was helpful!
Yes, these are great tips, and no one on these videos ever mention to use mortar for your final layer. I did the same thing. Poured concrete mix, screed and screed and screed and screed and screed lol and finally quit. It then rained after my first 3 waterings and left divots, mostly from not being able to screed all the rocks down. But if I would’ve known about the mortar portion, mine probably would’ve came out better too, but thanks for this great video and tips. 👍
I’m considering trying a recap of some sort on my slab. It’s all an experiment so I have no idea how it will turn out. If I do it I’ll post a video showing what I did good or bad then you can decide if it might work for you. Thanks for watching and posting your comment!
I have seen the Cajun videos and loved them, and always wondered if it really works. After watching your video, it has helped me to decide to try the dry technique. Thank you for sharing your mistakes.
Thanks for stopping by and I wish you the best with your project!
Thank you for your honesty in doing this video. Subscribed. 👍
I appreciate that! Welcome!
Thanks for the honesty! I just ordered 50 90lbs bags of Quikrete to try to make my first concrete project... A 40' X 5' slab to fill in the walk way on the side of the house. I'm planning to make it in ~2.5' x 2' stone sections. Sprinkling pure cement on top to make the surface smooth did come to mind! Thanks for getting that out of my head! Would have never lived it down from my brother (contractor) who's trying to talk me out of doing a dry pour in the first place.
I wish you the best!
Interesting video.
For most codes, foottraffic-only slab on ground requires a minimum thickness of 89 mm (3.5 inches)@3000 psi compressive strength.
If you use rebar, at least 40 mm (1.6 inches) concrete cover is required over the rebar.
If you use straight portland, you have to account for the chemical reaction ratio: 1/7. So you need six to seven times the amount of water during curing. 48 hours minimum before form removal or any weight set on surface. IMO regardless the thickness, the commercial standard of seven days curing (covered with tarp or film, 2xdaily mist until pooled) would be the way to go.
If you really want a thin slab, consider ferrocement as an alternative.
Thanks for all the good info!
@@DIYHomesteadProjectsDIYHP10 Even for DIY's some cities require permits, inspected, and an inspector on site.
This may be doubling up but I want this response brought to the attention of you bothe:
Even for DIY's some cities require permits, project inspected, and an inspector on site.
Appreciate your candor. Your experience and some of the comments will doubtlessly help others.
Thanks for stopping by.
Thanks for sharing. In others video, they keep mentioning more concrete to get the smooth surface. Motar top layer may look good on the surface literally but I think the durability is not there. Just something to consider beforehand.
I agree! I'm really curious as to the durability over time of the mortar top layer technique.
Thank you for the video. I did a dry pour based on the Cajun Country video having never done concrete before. There are probably some steps off camera that made the results better. However using just Portland doesn't seem to be a good idea since it lacks a binding component.
Interesting. Well, it was a good learning experience, next time things will certainly be easier. Hopefully since you only expect foot traffic it will hold up....fingers crossed. Thanks for posting this despite not achieving the results you had desired as it's really helpful for learning !
Thanks Joe, hopefully it will help someone else if they decide to try one of these "dry pour concrete slabs". I'm looking into some possible "fix it" solutions that I may try in the future. Honestly I think it's going to serve it's purpose as is but we'll see how it performs over time.
Thanks for sharing. Ran into the same problem with a rough surface and pebbles on top just a couple days ago.
One tip i found is to strain the larger pebbles out from some of your concrete and use that to fill in the low spots. Gets you a mix that plays well with the rest of the concrete and you don't have to buy 2 mixes, which is nice for smaller projects.
Thanks for sharing
Also the cracks is because you have to keep wetting it for the next few days. Get a longer screed next time. You need at least a foot ad a half hangung on either side of your form. That will give you the space for lateral screeding as opposed to only 4 inches of lateral movement as I can tell from your video.
Thanks for the tips, I appreciate it!
Love the frank, honest perspective. You tried. That is a success.
I appreciate that!
A really cool trick that always works for me, is to add all the water first, and mix it really well, that way you can get a stronger slab every time.
will that really work?
Thanks for taking the time to create this video.
I appreciate your humility.
I admire you. 👍❤️
I appreciate that!
Very admirable effort
So nice of you
Trial and error, thanks for sharing! I was wondering myself if could just use the powder concrete kind hoping for a smooth finish!
I'm considering doing something similar to this at the bottom of my new deck steps. I was thinking it would need to be 3 or 4 inches thick as well. Or i may go with 12 inch pavers. Thanks for the video
I wish you the best with your project and thanks for stopping by!

Is it perfect? No, but its a pretty damned good job for your first time. Thanks for making this video. I would have made the same mistake!
Thank you!
I really admire honesty. This video was very helpful to me - Thank You

You are quite welcome! I think it's good to show the failures too so others can learn from my mistakes. 👍
Subscribed off the back of your ultra honest appraisal of your own work ..an admirable quality…good luck from 🇬🇧
Thanks and welcome
I did a 2 by 4 foot, but thicker (about 3") and had the same experience. That was also with Sakrete High Strength. I screeded many passes and the surface got slightly better but never good. I had half a bag extra at my disposal so it wasn't due to lack of product. I'm reading that others say that Quikrete might have less rocks, and since my pour is so small I might start over and try that for comparison. Thank you for the video, it's very informational.
I agree with all that you said. I’d be curious to hear how it goes if you do it again using Quikrete. I wish you the best!
Thank you for sharing your project even though it didn't come out perfect. It was helpful to know some of your mistakes.
Thanks for watching!
This morning I did a dry pour over an existing small slab to extend it. I had some sakcrete laying around so I used that as the base and then topped it with quikcrete. In my opinion quikcrete has a finer powder finish than the other brand. I also finished it like it were a wet pour, I used a trowel and an edger to get a smooth finish and then put texture on it. I've never done any concrete work before, so I thought I'd start with this process vs the wet application. I did a 4 inch thick slab so there's another an inch on top of the existing 3 inch slab. I'll do the 8th soak in an hour. Hoping this works because I have lots of projects! Appreciate your video here .
Sounds like it should work pretty well to me. That’s a good idea using the two brands to your advantage! Thanks for sharing your idea!
you need to stick the second slab onto the existing slab, it's called keying in. It won't just bond together without a bonding agent, even water, neat cement powder, and broom into a slurry, then the 2 slabs will bond together.
I understand what you're saying. Thanks for sharing this. That slab looks really good for your first time. Great job, bro.
Appreciate that!
Aww, bummer that you had such a rough time, but thanks so much for sharing your project. I've been watching all the dry pours since Cajun Country Livin's, and I think this one is the first I've seen that shows things that could go wrong. I also really appreciate the tips in the comments for how to remedy it. I'm looking at my own projects soon. We're all in this together!
I wish you the best with your project and thanks for stopping by!
As a retired pool builder I highly recommend NOT doing dry pour.
It’s not really easier or quicker and it’s just stupid to think that you can dump out a bag and everything will be thoroughly mixed together for uniform strength.
Here is response from quickrete after I emailed them about this nonsense
Thank you for reaching out to us! We are aware of at least one video on-line, published by a source other than QUIKRETE®, which demonstrates QUIKRETE Concrete Mix being used in a manner inconsistent with our directions which will lead to a degradation in quality of the final product. Additionally, failure to follow package directions voids the product warranty. While we understand the desire to develop other methods that may seem to make use of our product easier or faster, our directions are developed after extensive testing to generate the highest quality results possible. In the video, QUIKRETE® Concrete Mix is poured dry for a small slab, then misted multiple times with water after the dry material has been placed. No QUIKRETE® concrete product is intended to be used for slabs without blending it with clean water prior to placing. Again, thank you for contacting us and do not hesitate to reach out with additional questions!

@@DIYHomesteadProjectsDIYHP10 next time you see a concrete worker eating lunch or at the hardware store or if you see them at a job site. Ask them.
Funny all these people that don’t know squat about concrete would rather take there advise from a couple in their backyard than concrete workers. Many have chimed in, and not one has said it’s a good idea.
But hey, I understand you’ve made up your mind and don’t want to be confused by facts
Good luck with your projects
I really appreciated this video. I had seen the dry pour videos before I poured a slab for an AC condensing unit behind my garage. I went ahead and mixed my concrete in a wheel barrow and dumped in place. While I had to mix 6 bags by hand, it wasn't terrible and after I worked the concrete a bit, it came out very nice. I'm not sure I would do a dry pour simply due to all the issues you had.
Excellent!
For all the 'problems' you ran into, the final result is still good. I'd recommend using 2x4's instead of going for the 1.5 inch thickness for beginners, then working your way up into thinner projects. For a given size of the project, thickness becomes your margin of error. Over water and allow for days for this to set up before giving it any load. Also buy a few more bags than you think you'll need. After the initial screed boarding you'll see rocks and that means add more concrete. I like to add it by the large scoop once it looks like you're close so you can minimize over spill, but if you're not worried about ten bucks of concrete just overfill from the start and shop vac it up.
I think you did a good job. I know you said you didnt have a lot of experience, but you tackled it. Kudos.
Thank you!
Looks pretty good for a first slab pour. The portland probably needs a lot longer cure time than you gave it as well, but obviously mortar would have been the better call.
I finish concrete for a living so this peaked my interest. This is a very cool little hack, depending on what you are using it for. Air conditioner pad, kennel, etc. Please do not do this anywhere other than your own home. You will certainly be getting sued or at the very least called back to replace it after 1 winter. Especially at 1.5 inches. That may work for a countertop, but not anything exposed to any kind of temp change. Thanks for sharing this with us. You learned something valuable no matter what.
I give you an A+ for trying. Although it doesn't look bad, I'm a firm believer that enough failures eventually lead to success...😏
Thanks! Yes the more you fail the better you will become. (eventually LOL)
I subscribed. Your video is a rare gem and offers a lot of real world insight and experience to ambitious first time diy'ers such as myself. Thank you so much for taking the time make, edit, and upload this video!
Thank you very much!
It's really not that bad at all.
Thank you :)
Thank you for sharing your experience. Right before you went to use the portland cement as a filler I was thinking the same thing as you. Glad I watched this! I would have made the same decision. My first dry pour will be a much smaller pad, a 3' by 4', to access a hose bib that I have to walk through mud to get to. I am planning about 3" thick.
Glad it was helpful!
Thanks for being so honest in your mistakes. Dry mix is really only useful for post holes. 4 inches thick is really a minimum, wet mix is the only secure way for a job like this.
Thanks for sharing your experience with the dry pour method , including your mistakes.
You are welcome, thanks for watching.
I find these types of videos way more interesting and informative than others where all jobs come out almost perfect because of the magic of editing. I appreciate your honesty and wish you the best in your next project!
Glad you enjoyed it!
I can appreciate the share. You tried it and that counts. And as others have said, it can be improved without needing replacement, if you decide to do an overlay!
You're right, I'm researching many options for an overlay. I haven't decided yet if I even need to do one. It really isn't all that bad but just not as good as I hoped. Thanks for your input.
Looks good and functional to me. I understand your frustration with the final concrete slab but better than a bed of pebbles for the entrance.
I agree and thank you.
I think it'll be fine. We used to broadcast cement on top of concrete slab to give it a smooth surface after it was pour. Great job!
I've also watch them pour dry concrete to
That doesn't just give it a smooth finish. If you continue to add cement and trowel it in hard, it will create an amazingly hard surface. This is usually done on large slabs. The next time you go into one of the big box stores look closely at the finish on the floor. If it's very smooth concrete with a shine, it's been done by lightly broadcasting pure cement over the floor during the time they are hard troweling with one of those big power trowels. The result is akin to using Gunite on a pool. The surface is impregnated between the surface sand with cement, resulting in a surface that is almost indestructible
I did a 30" x 38' dry pour on the side of my garage for a step and had a few of the same issues you had with the pebbles showing but overall I'm happy.
It was super simple to do and its rock solid. I did water it for a week and kept a tarp over it to retain moisture.
Its been a few months now and it looks exactly like it did when I "poured" it.
Excellent! Thanks for your input.
Thanks for being honest and showing the whole disaster.I learned what NOT to do.
You're welcome and thanks for stopping by.
Thank you so much! I’ve been thinking of dry pour, but I think I’ll stick with wet pour.
I read ya but I love the idea of dry pour simply because for my 66 year-old back it's far less physically stressful than mixing the wet stuff, and I am sick of labourers here botching everything they touch. I could fill a few sides of A4 with horror stories from when I had my house extended upwards a year ago. I'm in the Philippines and the lads here simply cannot get apprenticeships for trades like bricklaying, carpentry, plumbing, electrical, plastering etc - these kids leave school with no qualifications and many get a job working for a friend or relative and learn as they go along, usually from YT. I caught one of 'em trying to run a socket cable diagonally along and up the wall to the ceiling exit point - he'd actually chased out the plaster! That whole extension episode finished me with using local labour for important jobs. I've got 2 slabs to lay for small sheds and I will do it myself - dry!
Thank you for this. This video is more helpful to me than any of the other perfectly done dry-pours. I was more likely to make the mistakes you made than get it right the first time. Good on you for being able to show your mistakes so many of us can avoid some of these mistakes. Thanks again.
Thanks for stopping by!
Thanks for sharing the ups and downs of your project. I would have tried the Portland cement too without your advice. I might have tried to trowel the surface when it was wet to bring up the crème, but still have the sand and gravel mixer to hold it together.
Thanks for stopping by and sharing your input!
Thank you for sharing candid feedback! Must have been a great learning experience for your future endeavors :)
Absolutely!
fantastic video. Coming from someone who has never poured concrete, I learned a lot of what not to do and why not to do it. My initial logic on using cement would have been the same as yours. So thanks for saving me the disappointment.
Thanks 👍
Great vid. Thanks for showing the pitfalls. I'm thinking this is a perfect base to pave over if you should want to.
Totally agree
Learned more than any other concrete video. . .thanks for your honesty!!
Glad it was helpful!
