Screed has been in for three days and is still wet?

And then there are my screed layers, who simply tilted the windows wide open for cross ventilation ;)

Thanks for the answers. We have cement screed. So yesterday, on the third day, the neighbors were inside, apparently it's the condensation water that causes the puddles and drips down from the attic foil again. We are going there today. According to the site manager, ventilate completely for 30 minutes once.

After that, we start ventilating four times a day, first one side then the other for 15 minutes each to avoid cross ventilation.

Regarding the walls, currently Q2 but the painter is doing Q4.. I don’t know much about Q1234, just passing on what Mkr said about the weather.

From my feeling, I want to let it dry for 2 weeks first, then consider which craftsmen to bring in. It should be ventilated properly now. If it’s reasonably dry, then drywallers, electricians, etc. The painter should wait 4 weeks so the plaster can dry longer.

You will have to wait for the drywall installer. He should only start once everything is completely dry, otherwise you'll end up with mold in the drywall panels.

Do you coordinate the trades yourselves? A reasonable site manager should know the distance to be planned between the screed and the following trades.

Now in summer the humidity is of course very high. That makes drying difficult.

I always refer to the enormous amounts of water that are brought into a house with plaster and screed. I have always done it somewhat staggered because simply too much water would have come into the house.

When interior plaster and screed are installed, a few thousand liters come into the house and masonry. One should be aware of that.
And they have to be slowly brought out again. You can ventilate and heat as much as you want, it simply takes its time.

A painter or drywall installer would not come into my house at all.

Are you coordinating the trades yourselves? A reasonable site manager should know the distance that needs to be planned between the screed and the following trades.

No, actually the site manager. But since we can't always rely on him, we question everything and decide ourselves or tell the site manager what he has to do. Yes, unbelievable, but we do his work too.

Roughly estimated, I would say that interior plaster + screed for a house with 150 sqm living space are roughly around 15,000 - 20,000 liters of water. That's actually crazy.
