Plaster, pitch, paint etc. on the interior surfaces of the building. Is it possible to protect from moisture by applying materials or coating?

       If the interiors of the building are humid not only in rainy days but also in cold weather, and if there are swelling, mold, odor and similar formations as a result, this is because there is no thermal insulation. In buildings without thermal insulation, when the cold air coming from outside and the hot air inside meet on the wall section, the water vapor in the indoor air condenses and turns into water on the wall in the form of particles, and what we call condensation occurs.

       This is just like the condensation that occurs on car windows in winter and is caused by a temperature difference. After the cracks and damaged areas on the outer shell of the building are repaired with watertight materials, this problem can be easily solved with external thermal insulation.
