Bathroom tiles

[goodmow]

I am currently removing all the tiles in my bathroom but most of the plaster skim coat is coming down as well.

Instead of reskiming the walls could i fit sheets of 6mm marine ply to the walls and then retile on the top of the ply so that i am tiling to a nice flat surface?

If i can do i need to coat the ply with pva first?

But if your walls are now not flat & you fit ply, the ply wont be flat. It may get hollow spots & when you lean on the tiles they may flex off.

If you are only lossing 2/3mm of plaster you can tile back onto that, probably need to seal with pva. Im sure you will get a plasters opinon soon.

If your wall isn't too bad, I'd reconsider getting it skimmed - it shouldn't cost you that much.
If you decide to overboard it, I'd recommend using aquapanel instead of ply.
Remember to tank the walls before you tile in the shower area though.

What do you mean by tank the walls?
