ᐅ Proper Ventilation and Drying of Interior Plaster / Drying Time

Hello everyone,
are there any physicists or experts familiar with physics here?
I have questions regarding the drying of interior plaster.
In our new build, the interior plaster was completed the day before yesterday, and we are now considering how to remove the moisture from the house or walls as effectively as possible without causing damage, especially in the basement. The basement was also underwater by about 25 cm (10 inches) roughly two months ago. (Our house is built on a slope, so the basement is half underground, and the other half extends above the ground level by about half its height. On the basement side, there are four standard windows above ground level.)
According to various guides, some construction workers, and a drying company, in summer you should only ventilate at night when it’s at least 5°C (9°F) cooler outside than inside, and NEVER during the hot daytime hours. This makes sense from a scientific standpoint based on the water vapor saturation curve. Now, our question is: does this advice apply only to finished houses, or also to fresh interior plaster to help it dry quickly and effectively? We have read in other forums that, after plastering, continuous ventilation during the day is recommended, and that it should not be ventilated at night.
We want to avoid any mistakes in the basement in particular, to prevent mold growth!
Currently, inside the house during the day, we have about 82% relative humidity at 22–23°C (72–73°F). In the basement, it’s about 90% relative humidity at 18–19°C (64–66°F).
When we ventilate at night, the temperature drops to approximately 17–18°C (63–64°F) with about 70% relative humidity.
Another question is: how long should we wait after plastering before installing the floor insulation? Could any remaining moisture from the plastered wall migrate into the insulation and cause damage?
Thank you very much in advance for your answers!
Best regards,

I am currently having very good experiences with window vacuums for cleaning windows and spots with water droplets on walls (plaster).What kind of device is that?

What is this part?I imagine it might be something like a Kärcher window vacuum cleaner.Vicky Pedia15 May 2020 21:02Well, since @bauenmk2020 had such a good experience, I wanted to know exactly that...

Good question.
But actually, I can imagine that it works. We have a device like that, and even though the collection container is very small, it does drain well from the window. But do I need something like that if I’m not currently building a house?
