Tiling over existing tiles advice... - TilersForums.com

Hi Everyone, looking for a bit of help for my upcoming kitchen re-design!

The tiled floor is sound and flat, tiling over it will actually help raise the floor to a similar level to the rest of the ground floor, but I do have some questions!

I am using a 600 x 600mm porcelain tile with Mapei rapid set flexible adhesive, do I need to sand/rough up the old tiles and prime with something? Any other advice? (other than don't tile over tile

Have you tiled before? You're going to be better off with standard set adhesive rather than rapid set, especially with tiles that size.

Tiled a bit, but I was worried about how quick it will set! What would you recommend using?

I would say lift the old tiles. How long have they been down?
You could always level the floor after with a slc.

Probably been down for a few years, they are sound, just have a vision of the new tiles coming loose if I don't do something right!!

Have a read of the attached document.
but I would only consider tile on tile if you are 100% certain the existing tiles and substrate are up to it.
