Painted tiles

[tibby]

I've a customer wanting me to tile over his old bathroom tiles. I've done this often enough before where the tiles are secure enough, but these ones have been painted with tile paint.
I'd guess that at the very least the paint will have to be removed, though I guess most of you will tell me to persuade the customer to let me remove the tiles?
Thoughts and advice appreciated.

If i was you,i would have him get the tiles removed,and then go back and tile it once the walls are right.

I think I would be tempted to get them removed. Tiling on tiles is IMO asking for trouble but then to tile on to painted tiles is tempting fate. You will then be relying on both substrates holding up and you could have failure with one or both.

Hi
Tile on Tile is fine provided the existing tiles are sound. Generally don't use ready mixed (can be too slow to dry out) but Keraflex will do it.

However painted tiles I would say no for a couple of reasons;
1 background, if plaster or plasterboard, will be supporting too much weight.
2 weight of new tiles and adhesive reliant on a thin paint film having good adhesive and cohesive propeties.

I've lost a couple of jobs because I refused to tile over painted tiles.
I just don't like the idea of it at all. You see how easy it is to score off with a scraper.
Both times the customer either didn't want to scrape it off, or take the tiles off completely, themselves, or pay me extra to do it. And both times, no doubt, some other tiler came in and tiled over it.
But not for one second do I regret not taking the jobs.

Thanks for your thoughts, guys. Being able to say I've "consulted colleagues" seems top have swung it as customer is now willing to pay for some extra time for me to remove the painted tiles. I hope there isn't another set of tiles underneath.

Defo the right thing to do - new tiles are quite a large format and I don't want one of those falling on someone's head.

Just in addition to my collegue from Mapei above I share his opinion and...
...painted tiles are not a suitable surface to tile on and is not covered by any national tile laying rules, <- therefore you can´t guarantee !
