CotswoldDoItUpper Posted May 31, 2022 Share Posted May 31, 2022 I have an issue that I hope fellow Hubers have solved before. We removed tiles from a plywood floor and whilst the ply is solid there is a reasonable amount of thin adhesive left. We want to lay carpet (double stick method) over this. Do I: A) leave it as is and just lay over the top B) spend hours chipping off all of the remaining adhesive C) remove ply and re-lay new boards D) cover with thin (3mm ish as a guess, advice gratefully received!) ply and screw down thoroughly. Any help/advice/guidance would be great to help solve the issue! Thanks! Link to comment Share on other sites More sharing options...
Adsibob Posted May 31, 2022 Share Posted May 31, 2022 Easy, don’t lay carpet. Link to comment Share on other sites More sharing options...
Iceverge Posted May 31, 2022 Share Posted May 31, 2022 Run a straight edge across it, chip off any significantly high lumps and fill in any significant dips with tile adhesive. A thick underlay will absorb any remaining bumps. Link to comment Share on other sites More sharing options...
CharlieKLP Posted May 31, 2022 Share Posted May 31, 2022 I’d hire an orbital sander, and possibly grout the bits that were pitted. I can’t really tell if maybe you need a bigger sander, you could ask the person from the hiring shop. Link to comment Share on other sites More sharing options...
nod Posted May 31, 2022 Share Posted May 31, 2022 A simple quick Cheap solution Would be to use a self leveling compound to smooth over the adhesive 1 Link to comment Share on other sites More sharing options...

Use the proper primer, get the floor “sopping wet” as Uncle Nick always says with a cheap mop and then make up the compound with an extra litre of water per bag. Then let it flow … isn’t that right @Nickfromwales..?? Link to comment Share on other sites More sharing options...
CotswoldDoItUpper Posted May 31, 2022 Author Share Posted May 31, 2022 Ok, that might work. How thick can it be/does it need to be? Will it not run down any holes in the floor? Then how long to leave to go off? Carpet being fitted in 8 days! Link to comment Share on other sites More sharing options...
PeterW Posted May 31, 2022 Share Posted May 31, 2022 The rapid ones go off in 3 hours ..! Only needs to be 2-3mm thick to cover the worst of it. Block any big holes but small ones are fine - bit of filler if you’re really worried. Toolstation sell the Mapei compound which is good. Link to comment Share on other sites More sharing options...

Is it flexible enough to not crack up with the movement of the wooden substrate? Link to comment Share on other sites More sharing options...

I personally would remove the ply and relay with new stuff, but that is me and I just have a slight obsession with things being, as intended or without repair if that makes sense. For example I object to holes in walls being made and patched, I want a full sheet of plasterboard put in place! Link to comment Share on other sites More sharing options...

It's surprisingly flexible. And smells nice IMO ☺️ 'Tis what I'd be doing for certain. Link to comment Share on other sites More sharing options...
