Hi all,
First time putting up tiles so please bear with me if I say something stupid.
I've taken down some old times and I am left with what appears to be three layers.
1.) Old adhesive from the tiles I removed
2.) Plaster (I suspect)
3.) Plasterboard
My question is - Do I need to strip back all the old plaster right back to the board? At first this sounds a silly thing to do but it doesnt look in a fantastic state. It looks very porus and brittle (A good dig with a metal scraper can take it off)
Even though this is in a bathroom, I am confused at to if I should apply a PVA coat first to seal the wall or would that ruin the new tile adhesive.
Thanks in advance.
