Tile On Tile

[Two-Trowels]

Just looked at a job and they want me to tile over the existing 20 x 30 ceramic tiles on two walls - the existing tiles appear to be well stuck. It's higher than normal at 2.75m so I need to feel sure what I do is going to stay well stuck.

Would just a primer be sufficient (recommend me a primer please) or would it be better to go over it with backer board screwed on (with washers) on a 6mm notch bed of SPF.

What tiles are you planning to be fixing, remember weight issues come into play here.

Nope .. Don't do it . #simples.

Remove, prep , re-tile ... The best and professional way.

Hi mate , as long as those tiles are solid on the walls And you are only using a light ceramic wall I would use a primer called Mapei Eco prim grip then use a flexible cement based adhesive to fix new tiles but there is always a risk, as Dave says above get back to the original substrate if poss
