Fireplace Tiling Advice Please

[Rob Collins]

Hi

I have just stripped off some horrible mosaics off our fireplace to find they were only stuck on with glue gun and Silicon.

I am re tiling with brick slips which I have pre sealed already.

Do I need to PVA the surface before tiling? I am not sure what the surface underneath is. It looks like a mixture of block and old adhesive. I have attached a photo. The surface is solid and doesn't feel blown anywhere

Advice from a pro would be greatly received!

Cheers

Rob

Ooooooooohhhh PVA , get ready for the right answers , or have a look through similar threads on priming - before they attack

Prime with sbr...don't use pva.

I would either lay on a render coat with sbr or skim with a flexi.

Scrape off rough bits, prime with SBR then re-tile with Palace PC heat resistant adhesive.

Most single part flexi is fine for this job, I don't think anything special is needed.
