I am redoing the En-Suite and SWMBO wants it fully tiled. I do not have a problem with the actual tiling procedure but the original tiling was floor to ceiling in the shower area and half way up on the rest. The original untiled area is emulsion painted with vinyl gloss. My question is can this be tiled straight on top after giving it a key with a sander? I do not want to have to take all the paint off first unless there is a risk of the tiles falling off at a later date. If I need to take the paint off does anybody have any tips as my steam stripper will not shift it, I tried while removing all the original adhesive left behind after removing the original tiles!
TIA
John
