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

So there has been dust on the wood for a while, there's already mold! So much for this topic. I think the mold has been there a bit longer. We will clean it today and ventilate properly.

Then I have to say, the construction company is good, but only because we determine everything, follow up, defend ourselves, and get second, third, fourth opinions and don't accept everything. That's why I'm asking here.

The painter is not a problem, we postponed him to September, since he was hired by us alone, we can do that. I want everything to dry properly first.

Walkable is [Esttivh] after 3 days. Dry after 21 days and fully loadable after 4 weeks and also coverable, if the test results are correct... that was roughly the rule.

Well, almost.
With standard cement screed, you start functional heating after three weeks. This is followed by covering heating and cooling down. This heating must be carried out according to specified protocols (provided by the screed installer) (even though they often still mention 50 degrees there, which is nonsense nowadays with heat pumps but is still done for warranty purposes). The heating phase lasts about another almost three weeks. After that, the screed may be ready for covering. It depends on the measurement (CM measurement). To test yourself how dry the screed is, you can also place a foil on the screed and tape the edges. If it stays dry under the foil after a day, it is probably dry enough.

If you have installed special screed or additives, different rules of course apply. I had my screed ready for covering in less than a week and thus saved myself 1.5 months of waiting time. However, it cost about €2/m² extra for an accelerator.

I see bad workmanship here in the bathroom.

No moisture-resistant boards used. That’s not acceptable. Moisture-resistant drywall is always green, not gray!

I would have this dismantled here.

So either my screen's color accuracy is better or I have a color vision deficiency - but to me, it looks quite green compared to the gray walls.

Yes, you are right. Only now do I see it too, these green moisture-resistant drywall boards in the bathroom. How could I have overlooked that.
