Will be tiling walls in a couple of weeks, I have had to remove some of
the old tiles for other work just now and discovered there is another
layer of tiles below, so it was tiled on tiles.
For the best part of this room I wont need to replace plasterboard (so
far) so if I just remove the 1st layer of tiles will this be ok for
tiling the new tiles to?
How tidy must I get the bottom layer surface bearing in mind some parts
have adhesive stuck to them.
