advice on adhesive for tiling in a shower area.

[geo147]

hi i bought and used some everbuild aquaseal wetroom tanking kit. i dont have a wetroom, it is a normal shower tray with 3 walls lined with green gyproc. i have used the tanking tape to do the corners and used 2 coats of the liquid membrane.

what tile adhesive should i use now? does it now need a coat of sbr primer? im fitting 10mm granite tiles. ive heard about d1, s1 adhesive waterproof adhesive flexible adhesive, i dont know what it all means and would appreciate some advice.

thanks

If it gets wet it won't break down like a tubbed/dispersion adhesive and if your tiles are over 300 x 300mm a cement based addy is required.

Just reread your post and you say your fixing 10mm granite tile, do you know the weight per m2.

Im afraid you are over the weight limit for fixing 10mm granite to a waterproof membrane
