Drying with construction dryer

Hello,

The screed has been laid for a week and the underfloor heating has now been switched on for drying. Insulated with mineral insulation, it is plastered on the outside and inside as well.

You probably mean the standard drying program for the screed; in that respect everything is fine. A construction dryer will not be needed - unless wet and cold weather breaks in on us.

Now we are afraid that it will dry too quickly. Is this usual? Not that mold is caused.

If dried too quickly, "cracks" *can* appear; as for the problem of mold, you are far from it ;)

Rhenish greetings

What kind of screed is installed? With anhydrite, heating with underfloor heating is possible after one week, with cement screed it should be 4 weeks.

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

Could it be that you mean a condensate dryer when you say Bautrockner? As far as I know, this makes sense because it only prevents the condensate that forms from being absorbed and ending up in the drywall. However, it has no heating or drying function for the screed. As mentioned, it is purely used for collecting the condensate.
