Hello,

The cement screed has been installed for about three weeks now, and small black spots are gradually appearing on the drywall panels upstairs.

Ceiling with stains, flaking, and white plaster areas.


Unfinished plastered ceiling with white filler spots and circular markings.


Green drywall with many white filler spots at joints and corners.


Room ceiling with leftover filler and a hanging white cable line.


Is this mold? It looks like mold to me.

Is it just an impression, or is the insulation placed in front of the vapor barrier? Shouldn't it be the other way around?

In our case, there is an air layer above the drywall ceiling created by the battens. Then comes the vapor barrier (sealed with the distinctive green tape), and above that, the insulation.

I suspect insulation under the rafters

This is how it looks—the 20 cm (8 inches) insulation is installed behind the vapor barrier.

Hello

What is the current situation?
What is the moisture level of the building components?
Is, for example, an electric fan heater or drying equipment running now?

You can rent something like that quickly. Just search for Boels online. They are found almost everywhere.

You might have better luck checking classified ads like Ebay Kleinanzeigen or asking the screed installer. I find Boels to be quite expensive.
