opinion needed

Hi guys,
I have a client who has bought 300x300 floor tiles to put up on her bathroom walls! I asked if she was aware of this to which replied yes and then went on to say the guy at the store recommended them. I want to check what addie you's would use in this case. The tiles will be half wall except in the shower area above the bath tub. The sub is new plaster so will need to be sealed. Would Bal white star be suitable? or would Bal Grip be better?

Cheers!

Andy

Prime the walls and use single part flexible adhesive not ready mixed.

powdered for me as well dont forget to check the load on that freshly skimmed though(forgot what size/weight you stated)

**Daz** · 13-09-2008

Are they ceramic or porcelain? Either way, as per Sir Ramic, definitely bagged addy!

And what MM? Assume 9mm thick?

I agree, use a powdered adhesive.

Single Part Flexible would be ideal.

2 coats of neat APD.

Oh, and check the weight, you only have 20kg/m2 with plastered walls remember.

I would aslo recommend that you tank the shower area too, Andy

**ANDY5284** · 13-09-2008

Cheers for the help guys! They are ceramic tiles usual 9mm.
