Hi everyone. I have removed our old bathroom tiled floor down to the plywood sub floor. I am left with lots of patchy adhesive on the ply. I am going to lay new laminate. I need to make up a level difference of 10mm so was going to re board over with ply. Removing the old adhesive is slow going so was wondering how level I need to make the existing sub floor. Can I leave old patches if adhesive on there and just lay new ply over? Thank you.

How many square feet/metres are you dealing with? Are you using the correct tools to remove it with?
If you’ve got 6mm flooring ply laid over floorboards, would be easiest to rip up ply, clean up floorboards and start with fresh ply
If you’ve got 18mm ply, maybe a different approach - floor scraper (Big Mutt) or scraper blade in multi tool (but slow going)
Again, if you’ve got 6mm ply, this is more than likey gonna damage surface layers of ply getting off the adhesive
Laying ply over lumps of old tile adhesive is going to leave voids between the layers and be difficult to get the ply level
Best option maybe is to just remove the high spits of tile adhesive, prime with SBR, then pour a ‘flexible self levelling compound’ over the lot to correct finish level
No need for ply or removing adhesive, correct level and perfect surface for your vinyl - seems the way to go
