Lori Carroll, Interior Designer: Personally, I wouldn't recommend painting any wall tile. I'm sure it is done, but that is a job I would leave to the professionals!
Lisa Elkins, Architect: There is a paint called Break-Through that applies easily onto tile. So if you like the texture but not the color of your tile, a product like that can be an option. You'll lose the differentiation between the tile and grout, but if you like the paint color it shouldn't be a problem. Breakthrough was developed for garage floors, so it is really durable. But it does not come off easily.
David Portales, Spanish Tile Association: As for painting tile, if that's your renovation idea, abandon ship!
Verdict: Most of the experts we interviewed were not keen on painting over tile. But if new tile isn't an option, certain industrial-strength paints can work well on hard-to-paint surfaces.
