Too much moisture in the single-family house after screed installation? Risk of mold?

5 dry units for 5 weeks. Non stop. That's how it was with us :)

5 dehumidifiers for 5 weeks. Non stop. That's how it was with us :)

The underfloor heating is properly pushed up to 45 degrees using the screed program. It should then run completely for 3-4 weeks. Additionally, 2 more dehumidifiers will be used. After that, according to the heating installer/general contractor, the screed should be dry enough to be tiled.

Do you have such a big house or why five of them at once? And with or without fans?

Back then it was with fans and water hoses running directly outside. The house is also quite large.
It was a very unfortunate time recently with extremely high humidity outside. Ventilating with the windows was not possible. Furthermore, the house was left open in winter. It was a battle with snow and water...
Better like this than at a colleague’s place. There they had to replace the floor...

45 degrees for three weeks?
I wouldn't accept that.

No. Screed program runs starting at 15 degrees up to 45 degrees and then back down to 15 degrees - that takes three weeks. Maximum 2 days at one temperature level.
