Make Concrete / Cement Floor Over OSB Wood Subfloor

[@IntenseFitness2]

this is probably the best video on KZbin cause I've been searching on how to Epoxy over floor and this just answered my question. thank you for this video

[@codykinney7590]

I want this floor one day! Such awesome work!

[@mzamnesia7190]

Tysm! Laminate flooring in our dining/kitchen just ISNT it. The concrete will be much better ans this video was really to the point and easy to follow, thank you!

[@OligosFew]

Hey that is awesome....what is the price per square foot? Is this a weight issue for floors? What about impact....say I drop something heavy on floor? Do you think a person could work a small amount at a time if they dont have a solid period of time to dedicate to the process? Are there texture stamps to create visual interest? Seriously want to do this!

[@bengoerzen712]

I would love to hear these questions answered too! Really wanting to do this!

[@gerrys6265]

@@bengoerzen712 I guess he doesn't believe in answering questions...I'd love to know this too!...3 years later....

[@melaniegagnon8790]

Which stains are these? Nice colour!

[@Jonnorrisphotography]

Forgive me for having no construction experience but wanting to do something similar to my floors. What does secure the lathe to the floor do?

[@StonemanRocks]

Add 10% more water and you wont have those ridges and its not enough water to weaken the level quik! Level quik is good stuff! I have poured hundreds of bags of it ! Its hard as hell when it drys and poured over lath its going to feel like concrete under foot! Great job but try adding just a bit more water and it will make your life sooo much easier u wont believe it and no sanding / grinding those ridges!

[@garyteague4480]

Wow that’s a lot of work !

[@robertmillerleile1093]

Is the redguard typically only needed in a bathroom application?

[@shawnrobertzzz]

Was this done upstairs ? I assume so as it was done on a wood subfloor

[@garethllewellyn9278]

I have a 1000sqft home with 3/4 plywood flooring right now. I live in the Caribbean in an area where small earthquakes aren’t uncommon. I’ve been considering laying tile until I came across your video. All and all, is cost roughly the same as tile? Also, do you think there would be any issues with cracking? I figure the weight of tile and overlay would be similar also? Maybe the overlay alittle heavier.

[@rmtz59]

Might help others....use something with vinal in it, it expands.

[@jayholl371]

Can you replace the plywood with concert backer board?

[@sheengilyard]

What kind of tape is it the 3M paint resistant tape or the masking yellowish beige tape

[@No.Such.Nickname]

Nice work! Some stuff is unclear though. Can you please tell me what grinder disk are you using? Why leave the edges unfilled? I have seen some videos where they go all the way to the wall, while others put a barrier in before pouring concrete. Thank you!

[@mattcallister4811]

The music was just a delight to my senses.

[@BigDogRoy]

Im thinking DIYing this myself. Im trying to figure out if I should lay backer board first. Have you had issues with cracking?

[@stephen9546]

That’s what I’m trying to figure out to

[@Wowwow-wl3kx]

after egaliser and then possible to apply PU(polu utetane) on wood floor??

[@TrevorTownsendOfficial]

This looks like exactly what I'm trying to achieve in my small-ish duplex on the main floor. Does this product absorb a bit of flexing? If not, is there a product that does?

[@ExpressionsLTD]

To a degree... The cement based products typically can only flex to a small amount before a crack will appear. High acrylic(polymer) and fiber amounts in cement products increase the amount they can flex. The Epoxy we used over the cement floor layer though is more flexible. One area on this floor did develop a small crack in the concrete where the floor flexes, but it's been 2 years almost and the epoxy is still fine over it. There is a slight depression in the epoxy over the crack, but the epoxy is still bridging the crack no issue. If you did approach this on a floor that would be moving, you may consider applying the cement product layer and then letting it cure, settle, and crack if it will, and then use a Crack Repair (such as the TK=9010 from our website, I'll put a link for it) and fill those cracks, then epoxy coat the floor and it should correct the issue.

[@mitchellwalker6624]

now that it has been a year how is the floor holding up.. i was planning same type project have you got any cracks ?

[@NAUGHTYBIGFOOT]

Hey Mitchell, we did this on 3 different rooms/floors at the same time. The smaller rectangle shaped room it still perfect. The other two rooms had some complex angles in the rooms, which probably added a few stress points to the floor, and they did 'crack' but both have an epoxy floor coating on them (another video showing that process that we need to upload to KZbin still...!) So while there is a crack, the epoxy is covering it and didn't crack through the epoxy, just created a tiny line under the epoxy coating which when seen at the right light is noticeable as a slight depression along it. I suspect if we had waited longer before applying the epoxy, and allowed the floor to maybe develop any 'cracks' first, then done the epoxy, it would have filled in the crack and never have been noticeable afterwards. I would definitely do the process again though, and not be too worries about cracks because they just make concrete look, well like concrete (which is cool!)

[@mitchellwalker6624]

@@NAUGHTYBIGFOOT thanks for your reply . The info is very helpful . I may plan to do it like very large tiles . So there are places for the stress cracks to be.

[@Newtown-Orchard]

If I were also going to use electric heated cables, would those be applied on top of the metal lath?

[@j-deezy321]

Nice. Probably don’t need the primer with the wire I’m guessing

[@aenyrehman1083]

Thank you so much.

[@oscarherrera453]

Can this product work as well as self-leveling concrete?

[@artbysha8039]

No need to fill and tape the cracks?

[@kangurosalvadoreno5527]

Can this product be use on ceramic floor tiles?

[@christophersmith49]

Too complicated. You just get the 12$ let bag water repel thin set mortar and put directly on wood. Then out tiles over and job done

[@williepeppers2608]

hey... could i use a membrane instead of water seal?

[@NAUGHTYBIGFOOT]

Probably- but unless someone else has tried that... you might want to test it out. The elastomeric membrane coatings do a great job to seal off the wood and create a surface suitable for the cement to bond to- like RedGuard that we used in this video, or these that we actually now sell as well: www.expressions-ltd.com/collections/concrete-repair/products/surecrete-elasto-shield-elastomeric-waterproofing-and-crack-treatment-membrane

[@ashleylane2569]

What primer did you use?

So basically even if I’m not a professional I could do this myself for an affordable price?!?

[@jesusleon3611]

Yes

[@tlit3284]

Thank you so much. I was looking for that kind of floor 🙏🏻👍🏻

[@olawaseem]

It was stunning till the moment before epoxy

[@IntenseFitness2]

dont it? lol

[@jlai3861]

It's questionable if water proofing membrane like redguard should applied under self leveling compound, and what's the point to apply it first then staple the wire mesh to flood that punch holes through water proofing membrane? Always go with instruction to apply primer first then leveling then redguard if needed.

[@ra4ngernub]

the redguard is not there to make it waterproof. Im more worried that he uses primer on top of it, doesnt dry at all and just leaves a thin layer of plastic instead of bonding to anything

[@TileStonePro]

The Redgard is there for: 1. Seal the gaps between the sheets of plywood to the self-leveling won't run down between them. 2. So the wood does not absorb the water from the self-leveling. The primer is not needed at all in my opinion.

[@rodneycabot356]

Why did you sand the floor if you sealed it and covered it anyways plus everything else!!! Seems pointless

[@ELGee1]

Wy do a primer when redgard already waterproves it

[@ExpressionsLTD]

Primer can sometimes be an aid to waterproofing too, but is usually used as a bonding agent, to increase adhesion between product and surface. In this case, the steps were called out my the manufacturer of the overlay mix, so just followed along!

[@TileStonePro]

I'm not sure that Custom recommends primer over Redgard... Regardless, isn’t pouring on the Lath more than enough bonding?

[@dannomedic]

What is purpose of concrete over wood?

[@ExpressionsLTD]

We did it to add a flooring surface that we could then stain with Concrete Stains, as well as we did some 3D Metallic Epoxy coatings over some of it (other videos show this). Most flooring is about 1/2" high or higher, so when you have an adjoining room with carpet, hardwood, etc.... doing a cement base like this will bring this floor up to the exact same height, and then can be treated as 'concrete' with lots of design possibilities!

[@dannomedic]

@@ExpressionsLTD , thank you for reply. The reason I asked is I was curious about its use over a plywood floor in a storage shed. would adding concrete over plywood offer any additional weather proofing for the wood?

[@ExpressionsLTD]

@@dannomedic Possibly... but only if water was coming from the top down, then the cement layer would protect the wood. If moisture could attack the wood from underneath though, then a cement base over the wood won't do you much good, as it would crack and fall apart once the wood rotted under it!

[@firstlast-yn4qg]

don't concrete the sewer rough in!

[@codykinney7590]

Dumb question for anyone smart enough to answer, is it possible to do this type floor in a mobile home? My brain thinks maybe, like you'd probably have to reinforce the floor maybe?

[@ExpressionsLTD]

Any time you do a cement overlay on a wood subfloor, you will run the risk of the wood moving, expanding, contracting, etc. As this happens, the concrete will have a much higher chance of a crack. If you apply the cement overlay correctly, it should still hold true and solid, but would have crack(s). If you are okay with seeing cracks, then it might work out for your application. You can also try to mitigate the cracks by creating straight lines in the cement product from the get-go, so that if it cracks it will do so where you want. Similar to tile. And then you can control those defined crack areas with something flexible, like siliconized caulk (sold in caulk tubes by the tile products at your local hardware store)
