I've got an AKW Tuff form shower tray with a waste that is 10mm above the tray when fully screwed in. The Tiler laid my 5mm hex mosaic tiles on a 2mm bed, so obvs wasn't going to drain.
I took them back up and spoke to AKW, who recommended I put down a 3mm bed adhesive, let it go off and then re-lay tiles on a 2mm bed applied at 90 degrees to the first one. BUT - the tiler says it's v hard to follow the profile of a tray with an adhesive spreader, and also that a thicker 5mm adhesive bed will come up and interfere with the grout.
So what to do? Feels like I can
a) instruct the tiler to lay the mosaic mats on a 5mm bed (or 3mm bed with 2mm on the mosaic mats) and hope for the best
b) Put down a 3mm bed as suggested by AKW and hope I can follow the profile evenly
or c) If what the tiler says is true about the skill needed to use a tile spreader, find some kind of 3mm mesh to guide an even application
At the moment I feel like my best bet is option b) because the tiler dislikes a) and I can't see a product that would satisfy c)...
