ᐅ Mold on the basement windows after installing the screed

Hello,

the situation is as follows:

The screed was installed on Monday/Tuesday this week. The basement windows were probably closed. On Friday, I was able to enter the building again and opened the roof windows on the upper floor for ventilation. On Saturday, I also opened the basement windows and noticed black and green mold on the plasterer’s formwork everywhere.

Is this normal? Serious? Very serious?

What should I do?

Best regards,

Melrin

The construction dryer will arrive shortly. I’m mainly concerned about the transition period. Calcium sulfate self-leveling screed is used everywhere as the heated screed.

A vapor barrier is installed, and the entire building envelope is insulated.

Thank you for your detailed explanations.

Sure – it was a frustrating time for us as well because, despite the cold, everything was very damp.

We even had drywall installed, which started to develop some minor mold in two rooms – there was no way to ventilate enough, and despite using four dehumidifiers, it still happened.

Well, it wasn’t much and never returned after disinfecting.
