Bathroom walls are covered in waterproof paint. I simply sanded them and attached wall tiles with a anti-mould adhesive and grout. That was over a week ago and some of the tiles are now coming loose. Nightmare! Am going to remove the rest of the tiles I have done but what do I do next? Is there a product for stripping off waterproof paint?
Should I have coated the walls in something before applying the adhesive and grout? Either way whoever invented waterproof paint should be shot or covered in waterproof paint! Can anyone help please?

:cry:

Hi Catherine, best thing to do here is 'scratch' through the paint until you get to the background. This will need tobe done all over, but only in scratches. What I find easiest is a plastic rendering float with screws screwed through until they poke out the front by about 3 mm, put half a dozen screws in then rub this allover the surface hard. (You could also use a Stanlry knife to scratch through with, obviously being a lot more careful!!) Then brush everything loose off.
Once you've done this mix some PVA and water together at about a 50/50 ratio and add a couple of handfuls of sand in it. Paint it on the walls, let it dry and Robert should be your Fathers brother!!
Good luck

Thanks Adam, will give this a try.
