I tiled my own kitchen splash about 11 years ago long before I ever went in to tiling professionaly, I used b&q addy/grout all in one, the tiles are still on and solid! Also about 9 year ago I done my bathroom with same gear, I had to make window alcove out of 12mm chipboard and primed with pva, I retiled last year just really because I didn't do the best job with it.....anyway, the tiles where all still stuck solid!

I am only an enthusiast, so cannot offer the professional level advice, but...when I was tiling my kitchen I was advised to remove as much of the paint as possible. If the paint has been there for a while, it might come off with some light sanding. I ended up removing alot with light sanding
