How long to leave a screeded floor before tiling?
100 mm screed with underfloor wet central heating embedded in it. As I see it there are two issues: a/ the screed 'curing' ie hydrating the cement, and b/ drying out any excess moisture. Under the screed is 100mm celotex and a membrane, so moisture will be trapped between impermeable tiles and impermeable membrane. I do have a large industrial de-humidifier to help.AWEM
