Best tile adhesive to use on schluter

[tlogic]

Hi,

Can anyone recommend a good tile adhesive for bonding a schluter pre formed shower tray to a timber suspended floor. I asked Schluter and they recommended using Ardex S27 for the adhesion of the tray and X77 for tiling on Kerdi board. Trouble is none of the tile shops local to me stock ardex but only Mapei, bal and other branded adhesive.

Any recommendation on alternative to Ardex much appreciated?

A S1 adhesive will suffice 👍
