Quickstep glue down over ply

[phatboy]

Hi all,

I am flooring a large room with Quick Step glue down. I have all the materials ready to do, and self-levelled the concrete floors Friday. However, part of the room is ply and self-levelling over it would have made it too high.

Can I glue down onto the ply? And if so, do I need to prepare it with SBR or similar? Loads of demolition happened around it, so it is a bit dusty despite lots of clearing up.

Thanks!
Tim

Not a good start as the plywood needs to be clean to bond anything.
Start be sanding down the plywood and vacuuming it till no dust. Then prime it 4-1 and go with feather finish screed

OK, no bother to clean it up. I can mop it up too, gently.

Is PVA 4-1 OK, or would SBR be better? Feather can be finished to 1mm, right?!

Thanks for the help

Any further input appreciated, before I go and spend money

Get some floor primer mate. Sbr would do watered Down. Clean , 2 coats of primer.
