Tiling On Painted Drywall 10x20 Tiles

[theandroids]

Hey guys! Would you say it's ok to tile over painted drywall? Some people have been saying yes if it's not gloss paint. Well, the wall is emulsion so is that ok. Or will be better to apply Ardex P4 Primer to the wall instead?

Best to sand or scrape off the paint. For the little time it takes it's not worth taking the risk of tiling on paint even if it' really well adhered. Do it once, do it right!

Looks like there’s a hell of a lot of paint on

No, it was the fluffy type roller which caused that effect.

Would a grinder with a sanding disc be best Or a regular sander?

Don’t you just love fluffy type roller emulsion - it just washes off with warm water.

A palm sander or good old sheet of sand paper should suffice. Scraper sometimes will get under it nicely and work well.

Especially if they didn't put a mist coat on first .

Thanks a bunch! One more thing, should I try to sand back to plaster or just remove a thin layer of paint?

Back to plaster.
Always makes the mist appear when I see emulsion walls that are designated to be tiled.

Ok. Thanks, much appreciated.
