I need to change the fall to the drain; which to complicate things is not center. I want to use thinset to do that. I have a few questions if you know the answers. 1] is the finished height of a 12mm sq. notch trowel 6mm or 4mm? 2] is a 10mm layer of thinset too thick when laid in one go? 3] if 10mm is too thick what will be the result when laying a 10mm bed of thinset? 4] if I build the thinset in 4 or 5mm layers, will the layers bond to each other if smoothed off? 5] if the layers should not be smoothed off, what method would you use to rough the thinset? .....keeping in mind the need to maintain thinset height integrity. 6] which tile adhesive would you recommend for the purpose? I'll look into different shower heads and ask the plumber about some engineering and see what he says.
