returns to the south, the home is wet everywhere, moldy walls are common, wet furniture is used to it, and sometimes moisture will form droplets or even drip on the ceiling. So why? Now let's understand the reason why there are water drops on the flower board in Huinan every day.


when returning to the South sky, the dripping water from the ceiling is formed by the condensation of water vapor in the air on the ceiling. The air in southern coastal areas is humid in spring, and the air contains a lot of water molecules. During this period, the temperature began to rise, but the building has thermal insulation, its indoor temperature generally will not rise synchronously with the temperature, and the temperature of indoor wall and floor slab is still low.


in this way, the water molecules in the air will condense when contacting the wall and floor slab with low temperature, form water droplets and adsorb them on the indoor wall and floor slab. When the water droplets condense to a certain extent, they will flow along the wall or drip from the floor slab due to the action of gravity. This is why the ceiling drips when the southern coastal areas return to the south.

The door and window of returning to the south are not closed properly, and the humidity is too high: when the air humidity is close to saturation, the water vapor adheres and infiltrates the wall paint film surface for a long time, it is easy to induce mold on the paint film surface. 2. Check whether the external wall is cracked, which will also lead to mildew. 3. Check whether the upstairs residents have decoration. Once there is more water on the upstairs floor, it will seep down, and then lead to mildew. 4. Poor mildew resistance of coating: the materials used in decoration are not good. Due to the poor mildew resistance of the product, water vapor is easy to penetrate into the inner layer of the wall, resulting in mold breeding.
