Direct Answer • Key Takeaway
For Sand and Cement Expect 1Mm a Day Drying Time for Floors of 1-50Mm Thickness. If the Screed Is More Than 50Mm Allow 1 Day per 1Mm up to 50Mm and Then Extra Time for Every Millimetre over 50Mm. Using This Formula You Would Expect a Drying Time of 75-100 Days for a 75Mm Screed Layer.
