the Bostik single Stip has no upper limit on moisture ( in the slab) as long as there is not standing water or hydrostatic head present. The single Step is your safest choice.....the others ( Best etc.) only cover your installation up to approx. 15 ( using the CaCl ) terminology....
As in all cases with these adhesives.....the size of the trowel is the single most important thing to key on.....The trowel size determines the spread rate....the proper trowel is listed on the side of the can.....basically you are going to get about 25 sqft per gal coverage to get the full benefit of Bostik Ultra Set Single Step.
