Re:Painted Walls and Tanking

Hi Guys, i need some advise in this area, i have 3 showers to install and tile, all the walls have been dot and dabbed and skimmed and painted, i understand that cement board is the best option but i dont want to rip all that has been done out. so i saw the mapei water proof kit, looks good but it does not say anything about painted skimmed walls, could you advise me on this, can i just use the waterproofing solution and then tile stone tiles on top. should i sand off the paint first? please help. cheers, bob

You mention stone tiles, some are over weight for skimmed plaster anyway...

As above, I would be checking what weight your tiles come in at & then take it from there.

water ingress, is the least of your problems, skim plaster reducing the load bearing and secondly paint reducing it again ! take the p/board off and use hardibacker / cement board that can carry the weight of stone.
