What are the causes of mildew on the wall?

1, rainwater infiltration

In rainy season or rainy day, rainwater enters the room through the cracks in the wall, causing moisture from doctors around the window, which will be mildewed after a long time.

2, the external wall insulation is not enough

If the insulation layer of the wall is not well done, it is easy to appear that the wall is cold and cold, and the water vapor in the house becomes water droplets, and the wall is easy to be wet and moldy.

3. Poor water resistance

If the ceiling is not well waterproof, there will be water leakage and mildew.

4. Environmental factors

When we live at ordinary times, if we don't pay attention to ventilation, the indoor humidity will be too high, and the wall will be easily wet, which will lead to the phenomenon of moldy wall. In addition, the summer in the south is long, the air humidity is high, and the air in coastal areas is humid, so in the rainy season in the south, the walls are also prone to mildew.

How to deal with moldy walls?

1, simple processing

If its surface is only slightly moldy, we can first brush off these moldy spots with a toothbrush, and then take a rag and wring it out with water and gently wipe it.

2. Treatment methods caused by seasonal reasons

If this is the case, don't rush to repair it first, and then brush it after the water in the wall evaporates.

3. Insufficient heat preservation measures.

First of all, you need to determine whether the wall is insulated, and you can make a judgment by tapping the wall gently. If the sound is hollow after knocking, it means that the wall has insulation layer; If the sound is dull, it means that the wall has no insulation layer. If there is an insulation layer, it is necessary to check whether there are cracks in the external wall of the building. If there are no cracks, it means that the insulation material is not good and needs to be replaced. This is a radical cure.

When the wall is dry, we can brush the waterproof paint again.

If the wall is not well insulated, it will lead to cold. The cold phenomenon is moldy, black and furry indoor walls. The reason is that the indoor air is warm, the water vapor saturation is high, and the wall insulation effect is not good, so the wall is very cold, the water vapor will crystallize into water droplets on the wall, and the wall will become moldy and hard. Hair grows when it is wet.

Avoid long hair on the wall, mainly because the wall has better heat insulation effect. However, under the current technical conditions in China, it is sometimes impossible to handle it well. If the indoor humidity is too high, even if the wall insulation material meets the requirements, it will be moldy and hairy.
