I am going to tile over old tiles in the bathroom and I have seen that you can now buy tile adhesive by unibond that is called tile on tile has anyone used this and if so would you recommend
Thanks

Hi

Is there a reason why you want to tile over the existing tiles? If doing so, you've got to be extremely sure that the old tiles are on and not budging.

To be honest, tiling over existing tiles is not recommended for a bathroom in case either the old tiles were to detach from the walls or the new tiles didn't attach to the old tiles.

There has been a member recently who has tiled over existing tiles due to specific reasons. I'll try and find that thread for you.

GRR

As grr says it's not recommended,just imagine a child sitting in the bath an it comes down because the tiles underneath are'nt bonded strong enough. It would be your fault for tiling onto a surface that wasn't suitable.You don't know what the tiles are fixed to there could be weight issues.

walls or floor

Would'nt use the uni-bond, go to a trade tile shop and get some advise on powdered adhesive

Agree with whitebeam, unibond is a diy product, go to a proper tile shop and speak to them about cement based adhesives, they will also probably be cheaper, i cant believe how much the sheds charge for rubbish.

Is there any reason why you are leaving the tiles on and tiling over them, always a last resort in my opinion, why not rip them off and start with a clean slate?
