Hello everyone,
The interior plaster has been in place for 4 weeks now, and finally, the screed was installed in the house last Thursday. My neighbors, who are building with us, were airing out the house and mentioned that the attic is still very damp. Unfortunately, all the windows were closed when the screed was laid, and it’s extremely hot, so it’s currently not possible to enter. They ventilated the other two floors with shock ventilation. We will wait another day.
Now the painter wants to come next week to prime the walls and so on. However, I’m not ready for that yet. I want to ventilate thoroughly and let the screed dry properly first. I wanted to ask you if it’s really necessary to wait? We will be applying primer on the plaster and then spray paint directly afterwards.
What else should I consider regarding the screed, and when can flooring be installed on it? What work can be done in parallel once the screed can bear weight?
Best regards,
thank you!!

That’s quite nonsense. Drywall can handle that, just like the plaster that is applied to the wall before the screed.
But please, go ahead and block your construction site and alienate the tradespeople if you think you know better.Be glad if you have good and better experiences. We constantly have to protect our construction site from tradespeople who want to do nonsense. So please feel free to give professional advice, but don’t judge when we send tradespeople away, because this is my million-dollar investment at risk if something goes wrong.

A drywall partition carries a significant amount of weight concentrated on a relatively small area. I haven’t seen drywall partitions being placed or screwed onto the screed in any of the houses in this development.
Also, this approach will compromise the sound insulation.
PS:
How do you even plaster drywall after the screed is installed? It’s almost impossible to do it properly...

And doing so would also ruin the soundproofing.
PS:
How do you actually plaster drywall once the screed is in? It’s almost impossible to do that properly... Ah, now I understand you. I won’t be getting drywall partitions in the sense of walls that separate rooms, for example. In my case, the drywall installer will only cover the ceiling in the attic and conceal the pipes in the bathrooms. If I had wanted to separate the toilet from the sink with a wall, for example, it would have had to be done before the screed was poured.
But we don’t have that at all. It’s basically just about cladding.

And you’ll also ruin the sound insulation that way.
PS:
And how do you even plaster drywall once the screed is in? It’s almost impossible to do that properly...I don’t quite understand the problem. In our case, 1. parts of the screed were not covered with underfloor heating, and 2. parts of the screed were completely omitted to be able to do such “messy work.” And why would you plaster a drywall partition again?

xMisterDx26 Jul 2023 22:37That’s also problematic because it makes the transition from plaster to the drywall ceiling more complicated. Normally, the suspended drywall ceiling is installed first, then the plasterer applies the plaster to the wall and creates a trowel joint between the plaster and the ceiling.
I would have done it that way, if only to prevent the plasterers or other trades from accidentally perforating the vapor barrier with their tools.
With something like a butterfly knife, it’s easy to accidentally touch the ceiling, and if the ceiling isn’t installed yet, the vapor barrier is damaged…
In addition, the wooden substructure has to be installed beforehand anyway because it supports the insulation and vapor barrier. And wood is even more susceptible to mold than drywall?

I would have done it that way alone to prevent the plasterers or other trades from accidentally puncturing the vapor control layer with their tools.
With something like a butterfly trowel, it's easy to reach the ceiling, and if the ceiling isn't installed yet, the vapor control layer could be damaged...
On top of that, the wooden substructure has to be installed beforehand anyway, because it holds the insulation and vapor control layer in place. And wood is even more prone to mold than gypsum boards, right? I’ll show you some pictures in a moment.
