Well impressed with this stuff, left it exactly 30 mins ( enough time for a cuppa and a bacon roll) came back and it was completely set! Much better than the speed screed! The subfloor was well uneven so half of it was 3mm the other about 10mm and still dried well.
It's is great stuff isn't it . Really sticks well to subfloor too , which is always my greatest concern.
amazing gear had a little cupboard to fill (ply everywhere but a concrete cupboard!) so used a bag of super30 dropped whole bag in 1m2 and it had set in 20 minutes!
