No you can't, it's not suitable like many other gypsum undercoats.

Thistle dri coat would be advised

Yes mate but like everything depends on your tile weights.

I need to check the weights. It has said on the BG site that dri coat will take 20kg/m2. I know the tiles are not as heavy as that.

Add 4/5kg for adhesive and grout too!

Thank you very much for ur help.

British gypsum say no as it is one part of a two part system

I'm assuming I can tile onto multi finish then ??

After it's fully dried and primed with acrylic primer, not pva!
