Tile on Tile...

[christianbeccy]

Firstly, before you flame me, I know this is not ideal but hear me out...

I'm trying to put a bathroom together for a relatively low cost, it needs to do 1 year, maybe 2. It seems a little wasteful as it is, so I'm really trying to keep the costs down and can't contemplate getting a plasterer involved with the current restrictions.

I've tried chipping the existing wall tiles off, they are SO SO hard and aren't keen to come off at all. It's against my morals, but I'd like to just go tile-on-tile for this one. I plan to key the surface up with a grinder to give the best chance.

What adhesive would be best for this? I'm probably buying some 300x600 Porcelain tiles at £12sqm to go on there...

Tiling on tiles is fine as long as the old tiles are well stuck on

No grinder required just use sandpaper to roughen the old tiles to give a key and tile as you would normally

You need to go for a powdered adhesive rather than pre-mix as trapped between two impervious materials it needs to set chemically and not just dry.
