Drying of Flowing Calcium Sulphate Screeds (TrocknungCalciumsulfat-Fließestriche)

After the delivery of the floor screeds, we are not allowed to get in there for atleast four days.

During my research, I was able to stumble to this helpful article from Euromortar.com. It says... "Correct drying is therefore essential for flowing screeds so that they are speedily ready for application of surface treatments or coverings.

The following points must be observed when drying flowing screeds:

- The screed must be protected from draughts for about 48 hours after application.
- Intensive ventilation is required from the 3rd day onwards. The water absorption capacity of the air is dependent on the weather, e.g. on the temperature.
- Ensure that precipitation cannot enter through the open doors and windows.

Heating Floor Screed:
Drying of heating floor screed is accelerated by heating it up. The screed can dissipate its humidity faster and the air can absorb more moisture as it is warmed up. Hence, the drying time for heated floor screed depends on the nature and means of ventilation as well. Continuous closing of the windows to avoid heat loss simultaneously prevents drying of the screed. A constantly tilted window is also insufficient to quickly dry the heated floor screed.

We started the ventilation on the fourth day after the delivery/application. Here are some pictures as  of date.
