Hi everyone, I need some clarification on wall prep before I begin tiling. I have tiled three rooms before over the years, but didn’t realise how much of a Pandora’s box tiling the bathroom would be! I have been looking on this forum for answers for a couple of weeks, there are lots of very informative posts, but as some replies are different I thought it best I do my own post.
The bathroom hasn’t ever been changed since we moved in 30 years ago, except for me painting the tiles. I have removed all the tiles from the wall, most come off with no problems at all, some seem to have been stuck with industrial strength cement, and I damaged the plasterboard ( by the bath) Removing the tiles has revealed painted walls, and some sort of wooden box ( hiding pipes)which seems to be glossed. I was going to replace the damaged plasterboard with a hardiebacker board, but it seems very heavy and I had visions of it with the tile weight damaging the stud wall!
I want to know have I got to remove just the paint, or the paint and the thin plaster skim that is on the plasterboard before I can prime? And should I just replace the damaged plasterboard with a waterproof one or go with the hardiebacker? The tiles are 60x30cm 6mm thick porcelain tiles.
Sorry for the long post, thank you for taking the time to read through. I have taken photos, hope they are okay.
