What's the max depth I can fill with some kind of self levelling compound?
We've got some wonky concrete which is angled and higher than some floorboards in another part of the room. If been looking at ways to bring the boards up but what if....
We put some thick (16mm and above) ply/hardboard down over the floorboards. Then self level the wonky concrete up to the thick ply, then board over the whole thing.
I've seen some that do 10mm in 3 hours but is there anything that'd do 20mm. Can you do two sets of 10mm? I don't want to grind down the concrete or dig it out because it looks like a wet sandcastle underneath it.
