Large marble tiles and Mapei p9 - Tile Advice

[vman]

Hi

I have some large format marble tiles to fit onto bathroom walls. They are 10mm and 800mm x 400mm in size. They are quite heavy.
Do you think that Mapei p9 will be man enough for the job- I will be back combing ?
I have mainly been using s1 Keraquick for the floors but the p9 was cheap and looked like it might do for the walls job so I bought 4 bags.
I have no experience with the product.

Thanks
Robbie

I think the max size on mapei P9 is a 30x30 isnt it? it does say on the bag if remember rightly

On another note. Is your substrate capable of holding those tiles. ?

You are right I have just read the back . Thanks. Can you recommend an adhesive for these heavy tiles? Do you think the S1 Keraquick will do?

Hi Dave.
I was hoping no-one would ask this. I have moisture resistant PB, unskimmed and was just going to chance it thinking if made sure the tiles were on floor first I would get away with it . I know a cement board would have been better but the boards are up... Have you heard any horror stories of walls ripping off with weight?

Tbh no not from directly to PB. They are also quite thin for a large format marble. Are they mesh backed and resin?
