Liquid floor screed thickness.

The floor screed thickness when floating should be 75mm minimum with no maximum for traditional sand and cement and 35mm minimum with no maximum for modified sand and cement. Floating liquid screed thickness minimum with underfloor heating pipes would be 20mm for the specialist version and 30mm for the standard coverage above the pipes.
