Hi

I have a cloakroom, 3m sq to tile, it is a suspended floor half inch ply, with 6mm wbp screwed down at 150mm centre. I am using a nicobond rapidflexi adhesive on 300mm x 300mm ceramic tile, but the adhesive says to use a trowel that leaves a bed of 2-3 mm adhesive at the bottom with a groved layer above as its a timber floor!! I can't seem to find one of these and what are they called, can anyone shed any light on this please???
