ᐅ Question About Ventilating Interior Plaster

The interior plastering started on Saturday. Almost the entire attic floor has been plastered inside so far. The windows were tilted open. I visited this morning and fully opened all the windows. The windows were only slightly fogged up in some places. At the ceiling toward the attic (vapor barrier foil), water droplets can be seen along the edges. However, I did not find it to be very damp.

I am going again shortly to measure the relative humidity and temperature.

Currently, it is 10°C (50°F) outside and it is expected to get colder.

What do you think I should do regarding ventilation?
- Keep windows tilted open
- Close windows and then ventilate regularly with full openings

- Should windows be kept closed or tilted open at night or during low temperatures?

Hello,
generally keep the windows closed and do shock ventilation!!! Everything else is nonsense! Take a microfiber cloth and wipe off the water droplets wherever you can. Every little bit counts. Please avoid tilt position!
