Best tile adhesive for honed and filled travertine tile on top of AKW formsafe tanking

[Andrew Daughtry]

Hi I'm plumbing and heating engineer fitting a wet room with travertine tiles, walls and floor the room will be tanked with AKW formsafe tanking, what is the best tile adhesive for fitting travertine tiles i have always used mapei adhesive and grout.
Any recommendations would be much appreciated

I'd use a decent rapid white s1 remembering to back skim the tile and fill in any voids. The aim is complete coverage under the tile, as it always is, but it's more important to achieve this in a wetroom.

Mapei for me too.
