Under standardised drying conditions of 20c and 65% relative humidity ultraflo hemihydrate liquid floor screed laid at 40mm will dry in 40 days. With the use of under floor heating, a 50mm ultraflo hemihydrate liquid floor screed can be force dried in less than a month.

Under the same drying conditions 100mm of sand cement screed will take 180 days to dry thoroughly.  If surface finishes are fixed to a sand cement screed prior to drying they may subject to cracking as a result of curling or shrinkage.
