Hi, My builder opted to have a liquid calcium sulphate floor screed.
We have radiators in the building and the technical specification says we can "force dry it" after 7 days of being laid.
The tech sheet states that in ideal drying conditions Screed dries at a rate of 1mm per day up to a depth of 40mm and then at a rate of ½ mm per
day for any additional depth. According to my builder we have at the thickest point 65mm of screed. This means we will need to wait 3 months for the floor to fully dry out.
4 weeks have now passed and my builder is eager to start laying the tiles and wood floor. I am eager to get the work done, but am worried that it might all rot if the floor hasn't been allowed to cure sufficently.
The floor itself feels dry to the back of my hand. I have done a low tech test to see if I get any water condensation by putting a sheet of DPM on the floor. After a few days the DPM was still dry with no water condensation.
I am getting my carpet fitter to come out and test the floor with a damp meter to try and get a better idea of how dry/wet the floor is.
Any advice how to proceed? or what I should be checking for?
I am planning on putting down tiles, and a woodfloor with underlay with a built in DPM.
