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

So far, only minor work has been done, primarily on the outside of the house. Cement screed. Our [GU] prefers to take the time to let it dry properly.

So far, only minor things have been done, primarily on the outside of the house. Cement screed. Our general contractor prefers to take the time so that it dries properly.

They are probably starting to botch things now,... because then they won’t be on site anymore or something, I don’t know. I was able to stall them until next Wednesday, but that will be almost 2 weeks then. I spoke with the drywall installer, he covers for the site manager and said I should clarify it with him because he works on his mandate and not on mine ‍♀️‍♀️‍♀️ And as I said, he will probably be on vacation afterwards and then fully booked, so if it’s supposed to go quickly, he should do it before his vacation. He doesn’t really advise properly, but once he gets the order, he carries it out according to instructions. I then explicitly advised him not to enter the construction site without our consent.

Often it was like this, that the companies came without us being involved. I will ventilate until then and then see.

I spoke to a couple of other drywall installers, all recommend ventilating and drying for 2-3 weeks, especially now that it’s still raining so much and the outside is still so wet.

Since I didn’t have the nerves for discussion now, I am not replying to the email. However, the site manager also suggests leaving windows tilted to speed things up. Tilting has always been taboo for the neighbors so far because it’s not good.

We wanted to paint a wall in the HAR next Friday before the installations go on the wall. However, our painter postponed it because it is still too damp after 3 weeks. It's crazy if the drywallers already want to start with you now. I would have that confirmed in writing that it is dry enough and no impairments will occur if construction starts now. However, there is also no window in that room. We have had several windows in the house constantly tilted for several days now, but in a way that creates as little draft as possible.

Where is the problem supposed to be with the drywall? When the screed comes, the drywall ceiling on the upper floor and the drywall in the bathrooms is usually already in place. Of course, it gets damp during the heating for screed readiness, but the gypsum plaster, the walls behind it, the concrete, and the wooden substructure for the drywall ceilings are affected in exactly the same way. That’s why you ventilate... 3-4 times a day...
If that alone would lead to mold, there wouldn’t be a single mold-free house with underfloor heating anywhere in Germany...

Are you building turnkey with a general contractor (GU)? Then you have no right to decide when the craftsmen come. You don’t call VW and tell them not to install the engine block yet because you heard that bad batches are coming off the line.
Sure, you can forbid them from entering the construction site. But don’t be surprised if they don’t come anymore once you want them there.

If you don’t want to leave the windows tilted, which at least during the day at 20-25°C shouldn’t be a problem, you have to ventilate 2-4 times a day and, in that weather, also ventilate completely for at least 20-30 minutes. Do you do that?

And that comparison with the wooden house which was built in pouring rain is such an inappropriate analogy...

You wouldn't call VW and tell them not to install the engine block yet because you've heard that bad batches are coming off the line. Sure, you can forbid them to enter the construction site. But don't be surprised if they don't come anymore when you actually want them there.

If you don't want to keep the windows tilted open, which shouldn't be a problem at least during the day at 20-25°C, you have to ventilate 2-4 times a day and, depending on the weather, ventilate completely for at least 20-30 minutes. Do you do that?

Yes, we ventilate by shock ventilation 3 to 4 times a day! The screed is always laid first because otherwise the drywall would get damp from its moisture...

That's total nonsense. Drywall can handle that, just like the plaster that goes on the wall before the screed. But please, block your construction site and alienate the craftsmen if you think you know better. PS: And how are you supposed to install the drywall when the screed is already laid... and the underfloor heating underneath... good luck ;) No craftsman works so precisely that you won't accidentally hit a pipe. Glue it? Honestly... forget it...
