How long should the painter wait?

How long should one wait to start the painting work after plastering and after the screed? The screed was done 3 1/2 weeks ago, plastering was done 5 1/2 weeks ago. The underfloor heating's heating program has been running for 1 week. The rooms are now ventilated vigorously twice daily, which probably does not help much given the current damp and cold weather. The humidity level in the house is currently 80%. The floor tiles were laid immediately on the fresh screed. The wall tiles this week. All tiles are to be grouted by next week at the latest.

Has the new building actually ever seen a construction dryer?

No. If you wait through spring and summer now, won't it dry on its own then?

You can gladly wait with the painting work until after spring/summer. Then everything will have dried by itself (assuming ventilation), and the painter can begin.

Once again for understanding. The tiles were laid directly on the still fresh and not heated screed without measuring the moisture? What area are we talking about here? Do you have a special screed? With a drying accelerator

Don't you have to wipe the condensed water off the window panes every day?
