Hello, we completely renovated our bathroom in spring. Now, for a few days, a damp spot (diameter about 8-10 cm) has been forming in the ceiling plaster. It is directly on the exterior wall side. So about 30 cm away from the window. You can recognize it because the plaster (which was bought with a special wall paint for bathrooms from the painting company) is slightly darker. I blow-dry the spot once a day, then the moisture disappears immediately. But it returns within a few hours.

The moisture actually cannot come from above, since there is a normal wall there and at this point no water actually runs. It also doesn't drip or anything, it is just slightly damp.

What can I do about the moisture? As I said - I assume that the moisture from the bathroom has accumulated there - but I cannot really get rid of it....
