ᐅ Drying with a construction dehumidifier

Hello,

The screed has been in place for one week, and the underfloor heating has now been turned on to help with drying. Dehumidifiers are also being used. Mineral insulation was installed, and both the exterior and interior have been plastered.

Now we are worried that it might be drying too quickly. Is this common practice? We want to avoid any risk of mold.

Thank you

You probably mean the standard drying program for the screed; in that case, everything is fine. A dehumidifier will not be needed—unless we suddenly get wet and cold weather.

If it dries too quickly, cracks “can” appear; regarding the issue of mold, you are far from that concern 😉

What type of screed is installed? For anhydrite screed, heating with underfloor heating is possible after one week, while for cement screed it should be four weeks.

I would also not use a construction dryer. The natural drying is sufficient. The risk of the screed cracking is far too high. In our case, it was done after 3 weeks.

Could it be that you mean a dehumidifier with condensation drying? As far as I know, this makes sense because it only prevents the condensate from being absorbed and ending up inside the drywall. However, it does not have any heating or drying function for the screed. As mentioned, it is purely meant for collecting the condensate.
