thank you so much for sharing your experience. has given me the confidence to give it a go. massive respect to people who "give stuff a go" and share their learnings along the way. have subscribed!
Up until now rendering is something I would never have considered having a go at but now I reckon its doable. Thanks for the clear video. Your top tips section is a great addition.
Glad you enjoyed it. The tarmac OCR definitely makes it easier
I love this video because it makes me feel like I could actually do it and you are no nonsense.
Thank you so much for your vlog it has helped me so much we have built some planters just like you had and I had seen this render in B&Q and then looked it up on you tube and found you 🤩👍🏻 done my rendering today and it’s brilliant due to your help thank you Matt 👍🏻and loved your Vlog 🍺🍺cheers
Thanks Lee, I'm glad it went well for you and thanks for the comment, it brightened up my day.
Thanks so much for making this. Really appreciate your overview and review. About to use this in an old wonky wall that’s been increased a bit. Shall have to prepare myself for “fun” floating! Cheers!
No problem, Glad you enjoyed it and good luck!
Great video, good to see some honest no ego content. Helped me with starting out in rendering - thanks.
Cheers Dave, appreciate the feedback. Hope your rendeting went well
brilliant job!! - you've inspired me to give it a go!
New subscriber😁 ,needed a bit patch repair work doing and was going to use the tarmac 1coat so watched your video and answered my questions perfectly,very helpful mate 👍
Thanks! Glad you found it useful, appreciate the support!
Good demo. I used the same product to render low garden walls. I had a couple of places where I only wanted to render the front side and leave the back without render. My solution was to put boards along the back (with beads along the front). This gave me a good, even finish along the top.
Thanks. I should have done something similar with the boards but in the end i just covered the top with some decking boards, i'm really happy with the look in all honesty but I will know what to do if i have to do it again
We live and learn! I’m a DIY’er and rendering is a lot harder than it looks.
Thanks Matt for this video, it's helped make my decision to do some external rendering on the house. Best of luck with growing your channel ✌️
Thanks! And good luck with the house render.
Brilliant vid and thanks … just what I needed 🙌🏼
Great video Matt. I am currently tidying up me garden before going back to work so might give this a go before paying someone 👌👌
Nice one, i would always recommend giving it a go yourself, but i love diy so im bias!
Hi Matt,
A quick update on my project: the garage wall.
For anyone else considering this product, I went with the Tarmac one coat render and it went well.
I stripped all the old render and started from scratch. The wall is quite big at 6 metres by 3 metres but I did it in two parts and whilst the finish was not perfect it was acceptable for a DIY’er. I didn’t have a problem with my mixing paddle and a Hikoki 720 watt SDS plus drill and I used metal beads held on with screws and washers.
Thanks again for making this video. I found the straight edge and flattening was the most important part. Just get it on, press it on hard to stick well and flatten it after. The sponge float finish was the way to go and apart from a rain storm I got a fairly good finish. I found 5-5.1 litres was best for the water quantity and worked from right to left on the wall as recommended by another UA-camr for even finish. I went through 10 bags at around 10-15mm thickness and I too found myself polishing at 01:30 in the morning!
Good product but hard work!
Hi scooty, thanks for the feedback and update on your experiences. Its always nice to hear how other people have got on.
Hopefully my video and the comments like this help other people out.
Cheers matt
@@MATTDOESSTUFF2020 Im sure they will Matt. You’re video shows a good result straight from the bag and it’s a product I would buy again 👍
Thanks for this video matt, I'd never heard of OCR before, perfect for what I'm looking for 👍
No problem, its good stuff. Im really pleased with the look on the planters . Good luck with it!
Make sure you spray biocide on the wall before you render it or you could get plant and moss growing underneath it which will blow it off the wall
@@Surgeeon cheers mate 👍will do
I really like the section Stuff I learned, keep up the good work
Thanks, will do!
That was a good effort Matt. I’ve got a garage wall to do next week and there’s old render undercoat still stuck on so I’m thinking clear as much as I can and give this product a go. I’m fairly handy as are you and your video gives me more confidence to have a go with this.
Great video,
Thanks for making it and best regards
Glad you found it useful and hope your rendering goes well
I’ve just used it to render an outhouse wall. Never rendered anything in my life, it’s pretty easy to use. I wish I’d have watched the top about mixing half the bag first though then adding the remainder!
I need to go over it and do another coat though I think. Left it too long before smoothing it over :/
@@Stuey1221 im sure itll be fine, it took ages to go off when i did mine maybe i mixed mune a little wetter. Hope the 2nd coat goes well.
@@MATTDOESSTUFF2020 I called Tarmac today and asked their thoughts on using a cement mixer to mix it. The Technical department emailed me back and said yes, a cement mixer is fine but don’t mix it for longer than 3 minutes per batch as it’ll add too much air to the product.
Cement mixer it is then, just waiting for a weather window now.
Great video Matt
Thanks! Glad you enjoyed it
great vid. thanks Matt
Glad you enjoyed it
Looks good, we all start without knowing. Then we learn Matt
Cheers Hugo. Completely agree, you just got to give it go!
Well done mate ,been plastering 25 years looks fine,👍
Thanks, im really pleased with the way it looks l!
If you think your a plasterer and pass that god knows what your work looks like! It’s not great at all for a diy its passable that’s it
@@mcspad was thinking the same thing here.for a plasterer with 25 years experience to say it's looks fine makes me laugh.for some 1 with no experience it ok
@@emmettmccarthy7247 and it’s trolls like yourself that can only sit behind your keyboard knocking other people that bother to make content when you probably have no idea yourself.
Haven’t you got something better to do than troll people? It was a valiant effort and a video that clearly many people found useful. You need to learn to behave on social media and have some manners
@@scootyman2974 ya that's it scooty man now scoot on u bandicoot u don't have a clue about me or what I can do.and no I don't sit behind a keyboard as I don't have a computer,get a life man
nice vid - especially the "learnings"
Tha ks glad you enjoyed it
Matt, brilliant video which has given me the confidence to sort out a garden wall. The first video I could find anywhere of Tarmac OCR being used by a fellow DIY'er. Just out of interest, did you use all 4 bags for the project? Also, did you do anything to cover the visible beads later on or have you perhaps just left it and painted it over? What size beads did you use? How long did the actual rendering take you? Thanks once again - top man and easy to understand.
Nice one, glad you enjoyed it.
To answer your questions.
I used 3.5 bags in the end, I'd say coverage on the bag is pretty accurate at 10-15mm thick.
I am going to paint the planters at a later date so should cover the corner bead
I've updated the description with links to the beads. 10-12mm from screwfix. you can get deeper but these worked for me.
the actual rendering took about 2 hours (not including setting beads). I had to do 3 separate mixes, it would have been quicker to mix up a larger batch but i was limited by bucket size and mixer.
Fair play for having a go at it, nothing else to say really.
Thanks
Good video 👍
Thanks 👍
Hi with this render, can I check if there has been any cracking or peeling anywhere 2 years later? Also I have got red brick external wall - will this work and do I need to prep the surface before or just put on this one coat tarmac render ? Thanks
"why sell it in a DIY shop" hahahahahahaha, what a cracking point!!!!!! 👌🤣
haha, thanks!
Nice bodge job! As long as the misses was happy 😳
Thanks for the comment. It was my first attempt but im happy with how it looks, thanks.
You had me at “drinking beer” 😂
Haha. I personally dont think any DIY job is complete until i've admired my work with a beer in my hand!
The wall you built your flower bed against could do with some repointing as well!
Haha, I know but instead I clad it with wood! check out the video on my channel
Can this be use on an outside concrete ground? I need to smooth out bumpy concrete but the exterior leveller I was looking at is too expensive per bag for me to afford. £30 a bag. This is significantly cheaper so can this be used instead? It's for a 3mX2m garden floor. I want to smooth it out as a small outside space to practice rollerskating moves. It's currently too stoney and very rough.
Im not sure to be honest. Its essentially a cement based render but not sure how it would hold up under footfall. Might be worth contacting the manufacturer
Good vid! I am going to try this first time this weekend! What about the plastic beading you can still see on edges?
Im painting the whole lot so hopefully wont see them. I guess i could have tried to cover them more but im not unhappy with the way they look.
@@MATTDOESSTUFF2020 thanks mate!
The edges of the plastic beads are ment to be visible when finished
Just about to do this to a wall I've built, what size beading have you used 6/10?mm? Did you have a DPM on soil side and did you waterproof the wall before rendering? How has the wall faired since you built? Lots of questions...sprry
The beading is 10-12mm. The link to the beading is in the description of the video.
The walls have held up really well the render is still on and they still look fresh so im pleased so far!
@@MATTDOESSTUFF2020 fantastic pal, thanks for the video
Thanks for making this. When we came to floating the float made the render really gritty in places but smooth in others? Did you have that problem or do you think
It was too soon ?
I had a grittyish finish, but i quite liked the look. if you wanted smooth I think you would have had to go over with another trowel. But as this is the one and only time I've used this i couldn't be sure.
@@MATTDOESSTUFF2020 thanks for responding I appreciate it
@@MavenProductions247 no problem
Great video, How thick did you do the coat? Says minimum 16mm I think. Going to do my garden room bank holiday weekend (this weekend) bit nervous because it’s a big area and i thought the beading would be a guide but it only sticks out on the corners about 5 mm so will have to build up rest by eye.
I did about 10-20mm across the lot and if i did it again i would probably use a straight edge across the beads to guage the thickness.
@@MATTDOESSTUFF2020 that’s what I’ve just done on the front, used the poly float to soon and scratched it a bit but hopefully paint sorts that out haha. not sure when to sponge float it though.
I sponge floated when it was still wet, but when i prodded it with my finger it didnt make an imprint! If that helps!
For rendering I always add lime it helps preventing cracking.
nice i'll add some next time. although 2 years in and its holding up well with no cracks
Hi there nice video looking to render on an old house contemplating fitting a bell cast drip bead to take any water away from the wall this would involve two coats any thoughts or tips ? Thanks
Thanks!
I dont think you would need two coats. Ive used what im calling stop beads but i think they do the same function (im not a pro) but i think as long as you can get them fixed to the wall you should be fine with one coat
I think in a normal scrstch coat situation you would set the stop bead into the first coat but with this youd need to fix it another way
@@MATTDOESSTUFF2020 hi Matt thanks for reply with this one coat render strange question but could you put two coats on to bed the drip bead in ??
@@dm7325 Yeah for sure, on the back it says for thicker applications you should build up in multiple coats.
I would actually recommend setting the beads in some of the render anyway rather than what i did with grab ad. So doing 2 coats would work. I think if you are doing 2 coats you would need to scratch the first to get a key for the second to stick to.
Just put your second coat on the next day mate .This ocr does not board up as good as sand and cement traditional render ,this stuff is used as a base for 1.5mm silicone finishes .
Didn’t even rule it flat !!! Looks good from my house
looks absolutely horrible !!!
Thanks conor. I didnt think ruling it off would be needed as they were such small areas and i was rendering between beads. It ended up pretty flat but a bit rough. Would you always rule off??
Im pretty happy with the result being my first time doing it. What could i have done better (other than pay a pro!)
Do you think you would have better doing a thin scratch coat then 1 or 2 passes with the OCR? I really want to give this a go. Been told add a bit of SBR. Looks pretty good for been tarmac.
I only had a thickness of about 15mm of the OCR. i'm not sure if a scratch coat would have made a difference to times or not and i was keen to test out its one coat credentials. it does say on the back it can be built up over 2 coats.
As for SBR are you talking about adding that to the mix, if so i'm not sure, you might be better with an accelerator if you are worried about time.
I did consider putting some SBR on the blocks but i think thats more to regulate the drying times and i was getting conflicting info online so left it out.
I am really pleased with the finish though.
@@MATTDOESSTUFF2020 i only have a small ugly wall to cover up so i am very interested in seeing if the tarmac stuff is any good to learn on. I was told to make things easier sbr walls, add scratch coat then beads. Then mesh & topcoat. Im unsure if they meant for the likes of krend or webber. I’d like to do a scratch coat finish so maybe i’ll do the 2 coats do you think?
@@danmurphy7338 I dont think you need a scratch coat with this stuff but as you say you could lay your beads into it and then put on a top coat so might work well.
I think for a small wall its ideal stuff as you dont need to worry about getting the right concrete mix.
I think if i was to do it again id probably put some SBR on just to see if i saved time.
@@MATTDOESSTUFF2020 il give it a go pal. Looks good for what I need. I googled what i meant and it was sbr & weatherproofer. Maybe just to help coat for if people wants to paint it, im not sure. I loved this video so thanks for sharing as i’m 100% going to use that tarmac stuff. Cheers
@@danmurphy7338 no worries glad you liked it! And good luck with your rendering!
Never mind the planters you need to give your workshop a coat :)
Hah. It does indeed! Didnt buy enough for that though
Your a kool guy God bless you brother in Jesus Christ name
Thanks
Your welcome 😇
Ive just applied this to a brick wall...how long to wait before floating? Its quite warm outside.
If mine comes out as good as urs, il be happy.
Id wait until your finger tips dont make a dent in the render but still feel damp to the touch. Not sure how long that will take but its a good indicator i think
@@MATTDOESSTUFF2020 nice one....so a good few hours
Did u use 4 bags on all those planters?
I used 3 and a half in the end, at about 15mm thick
@@MATTDOESSTUFF2020 Thanks Matt!
Do u think I could use this on a pebble dashed wall?or do I use render grip first?
A 25kg bag doesn’t go far!
@@MrPFurse I would put something on the wall, maybe some SBR as I think i'd be worried about the suction and it drying out too quickly. you might want to ask a pro though as i'm by no means a pro at this stuff.
i would say your always best buying sand and cement you more control on how strong you want how quick you need to it try etc and convenience products generally aint as good
yeah, I wanted to try it , mainly because i was being lazy and was hoping the one coat would save time! It did the job though and its still on 2 years later and hasn't cracked or broken. i think maybe i made it too wet which affected the drying time
For a first attempt it wasn't too bad
If you did it again you would do a better job
Practice makes perfect
You cannot use pink grip to put any render beads on especially external I've been plastering 38 yes what is the matter with these companies selling shit to DIY people it's fu,,ING wrong please understand you getting ripped
thanks for the feedback, what should i have done instead, always happy to learn
Please render your beads on stay away from edge of bead keep it clean then top coat finishes over and into beads job done
Rough as hell
Thanks for the comment, I hope you're talking about the render and not me!
The finish probably could have been smoother but I'm happy with the result
You're a fine specimen sir not rough at all. As long as you're happy with it that's the main thing. I'm a renderer. If anyone comments on it when the sun is shining on it just say its rustic!
@@G2020- haha. Thanks, ill remember to do so!
Eehhmmmmm!
thanks!
errrrrrrmmmmmm top tip on ermmmmmm how to get a million errmmms into a 14 minute vid ermmmm lol
Thanks
Rough
it is a little, but i'm pleased with the result!
No need for that comment
Won't last 5 minutes unfortunately. Hats off for the attempt, but done completely wrong.
Thanks for the comment j bo. What did i get wrong? Im always happy to learn!
Thanks Jbo look forward to seeing your video on rendering, pillock!
@@coombsy1986 haha, love this comment and no reply from pillock! 😁
