Hi
When I used the Unibond cement based adhesive (which behaves like
mortar and spreads on wall using plasterers trowel, but I dont know
if its any stickier than mortar), I put on about 8mm thick in 1 go
with no problems with the tile slipping.

Yep, this is definitely one case where the powdered tile adhesives
outperform the ready-mix generic stuff by a mile.
