If you decide to do it again, try a different adhesive. I used Ardex Flex
7001 Timber System and it was excellent. It certainly didn't take 48 hours
to set. The tiles were 600x400mm slates. It's been down for over a year
and
there hasn't been so much as a crack in the grout (Ardex Flex FL).

Same stuff, same application, same results, 2 yrs down the line - very very
happy - not cheap but then again I was putting down slates which weren't
cheap either
