MODERN BUILDS
Hi, My name is Mike Montgomery and I'm a MAKER; a designer, builder, and full-time content creator. Accessibility is my focus with Modern Builds, not simply accessibility of designs, but accessibility in materials, information, and projects themselves. I've focused on creating furniture and DIY projects that are simple enough that any beginner maker can accomplish, yet interesting enough that any expert might be inspired. Building and making is becoming less and less of an exclusive hobby and profession. My goal is to reduce that separation even further.
You could just… pour it on the floor from the buckets…
This isn't what this product is designed for, there are cold joins everywhere which will fracture and crack and there are no expansion joins anywhere. He should really do a update video in a year to see if it has cracked through the doorways, cold joins and see what damage the floor has received from general use
Pro tip: Don’t post DIY videos unless you know what you’re doing
That’s not a floor lol that’s what the flooring is supposed to go on top of 😂 to each their own but it looks like a level flow job site and not a living area.
What a massive waste of time just pour it from the mixing bucket and roller it. It’s self levelling just prime and seal the floor so the old floor does not dry it out and it will flow on it’s own
Reproducing Ben Uyeda’s video?
I feel like you’ve been making these vids for too long to have your audio sound like that in the shots where you talk in frame.
$2000 in concrete??
I am very concerned this will crack.
No matter how low I put my volume on, you still talk too loud.
That slurry will form fine cracks overtime, despite having been protected with a sealer. It might not do anything to the floor structurally considering it's a single storey house but it will be visible. Now, if you want to prevent that, lay down a layer of fine mesh (preferably a fibre mesh instead of a metal one as the latter would expand when the concrete sets, creating uneven waves) before pouring in the self-leveler slurry. The mesh will provide tensile strength, preventing any cracks from forming on the floor...
I've installed more than 1 million sq ft of Ardex K-15 self leveling underlayment in New York city rehab projects. Hat's off to you for thinking of a new way to dispense the mix, although it has some bugs to work out. On big projects we used a concrete pump and gauge rakes set to 1/4 inch to guide the mix where it needs to go. We then went over it lightly with a long handled type of float to break the surface tension and allow it to flow better. Once it cures you are always going to get tiny hairline cracks that are actually mostly a cosmetic issue, and not a structural problem. It should be sealed with a clear water based matte urethane because it will continuously dust off and you will always have it on your feet if you don't. These materials were designed to go under finished flooring, and not to be the actual floor.
This is excellent. I've donethis to a floor with 5 gallon buckets and it was extremely tedious. This set-up is fantastic. I made the mistake of letting part of it dry too much before the next pour, like he did. Really imperative to have the next batch ready to go. Definitely best to have someone mixing while you pour.
This works great as a floor underlayment, but it is going to crack. Cementitious products will lose moisture over the next few weeks and continue to harden and shrink and creep. It's just the properties of products themselves. This is why sidewalks have joints in them and why slab on grades have saw cuts typically 20-25 feet on center to allow cracks to form along that joint.
Nice job guys! It looks great. I have a 70,000 sq foot 1927 five story office building. The floors are cement, but poured in small sections which are not level nor flat. Fine for carpet, but we wanted to change to wood (laminate planks). I am just a DIY, not a contractor, but I have done a LOT of these pours (200 to 2000 feet). The first step is we grind down the high spots at the corners and edges of each original pour. Then I like to use this self leveling stuff. It is SIX TIMES the cost of regular cement, but it flows like thick soup. It does NOT in fact self level all that well. Especially if you do it like these guys did, in large pours. The thing is, it sets in a flat amount of TIME, not by drying out (it is a chemical reaction), and that time is just a few minutes. You do not really have time to fuss with it, and if your next bucket is not ready pretty quick, the earlier pour will set before your next pour, and it will not be homogenous (you will end up with dry seams instead of a continuous pour). So, there are a couple of tools we use. One is the beveled cement float (like a push broom for shoving around cement)(A gage rake probably works too). This is used right after you pour a bucket to get it into the corners and edges quickly (time is of the essence). The second tool is the spiked roller (think pinhead on a 18 inch wide paint roller). This is used to QUICKLY smooth it all out and blend the different pours and pop any bubbles (careful not to push it too fast or it will spray cement all over your walls and pants), and do not overdo it, once the cement starts to set, it is game over. The shoes with spikes are cool if you need to walk into it and hit a corner and not ruin your sneakers. Also the cement dust while you are pouring the bags and mixing is very irritating. If doing it outside is not practical (limited time before it sets), set up a place inside (with a heavy drop cloth, it will make a serious mess A CEMENT MESS). I usually have 3-5 people to do it. Have a big trash can of water and a 10 quart bucket with a slot cut horizontally at the 6 quart level so you can quickly grab exactly the right amount of water (the water added needs to be precise). So I have 1 guy on the half inch mixing drill at the bucket, another guy pouring the dry bag into the bucket, and a 3rd guy holding the vacuum with a cyclonic dust extractor (DustDeputy). After the bucket is mixed, a 4th guy will bring it to active room, and pour it out. The final guy then uses the float and pin roller to blend it into the ongoing pour. Have 2 or more buckets in circulation so you can do it assembly line fashion. Note that it sets up and coats the buckets as you go (I can only imagine his trash can thing and spout getting clogged), so having a few extra is nice so you don't get hardened clumps in your pour. Do be sure to wet mop the floor and then put on the primer (like he says, 1 time 50% diluted and then 1 time full strength). The directions say to use a soft push broom to apply, but a cheap paint roller seems to work just as well for me (make it thick, a 3rd coat is not wrong). If you are sloppy with the primer step on an old floor, it will wick out the moisture too fast and in the morning you have a cracked useless mess to chip up and redo. f you don't tape the edges, it will flow right under baseboards or drywall (or cabinets or doors). DO not skimp on taping and sealing where you to NOT want the liquid cement to flow. Caulk cracks in the floor or it may flow through (to the floor below you). Also I can say from experience, this self leveling stuff is rather soft so do not expect it to be a walkable top coat. In fact the manufacturer's website is very clear NOT to leave it as the final surface, it is UNDERLAYMENT, although it is pretty, it is NOT durable, and a thin urethane coating will not make it suddenly durable (note however that there are professional self leveling mixes that ARE certified as a topcoat, but the ones I have found require an authorized installer to buy it).
We in the UK use a large spiked roller like a paint roller but with spikes, it gets the floor level and breaks any lumps up.
I just called the company that makes this stuff & they said it is only to be used as an underlayment & not for an exposed concrete floor. They said because of pressure points it will crack. I also called a concrete specialist about doing this & he said you need at least 3" of concrete to get to the necessary PSI. 1/4" or co will crack & possibly shatter like glass. I'll be curious to see how yours holds up over time.
I dont understand all the hate. For a two person job I really don’t see the suggested comments where they say it should just be “directly poured on floor” working out. Too many seams with walking back and forth and opening bags etc. I think this was an excellent way to build a tool that saved your back, your time, and a lot of headaches running around trying to prevent a seam from each bag. Great job
this looks like it worked a lot better than I would have thought. Use a spike roller next time, it would have made a huge difference
Just when I think you can't do anything better you go and outdo yourself. Well done my friend.
