Likewise generally Nicksey, rarely do a set in under 3 hours but always do big sets. I have been known to put on two coats from the same mix if it's just a small area left at the end of the day....I'm not proud of it :-[ ;Dive been doing 11 bags in three sets and there taking 3- 3.5 hours each ..roughly 1hour and a half to get it on and hour and a half to trowel up ..........when it starts getting really dark and cold you tend to lay just two good sets on
