I had anhydrite screed laid 28 days ago, commissioned ufh 21 days ago and have proceeded to test with a hygrometer for RH test. Its showing 45% which seems low given the threshold is 75%.
The question comes from when I move the odd item like a cardboard box, where the tape has been in contact with the floor there is a damp mark suggesting moisture still working its way out. Is that normal in a screed that is testing as dry as it is?
May also be worth mentioning that the plan is to lay porcelain tiles on ditra.
Any advice or thoughts welcome as I'm stumped at the moment.
Cheers
