Rain infiltration
In the rainy season or rainy days, rainwater enters the room through the cracks in the wall. The doctor has caused the surrounding of the window to be wet. A long time will lead to mildew.
2. Insulation outside the wall is not enough
If the insulation of the wall is not good, then it is easy for the wall to be cold and cold. The water vapor inside the house is turned into water droplets, and the walls are prone to damp and mildew. 
3. Waterproof is not good
Waterproofing of the ceiling surface is not done well, and water leakage and mildew will occur.

If its surface is only slightly mild, we can use a toothbrush to brush off these moldy spots and then wipe it gently with a rag and wring it.
2. Treatment due to seasonal reasons
If this is the case, we should not rush to repair it first, but wait until the moisture in the walls has evaporated before painting and then refinishing it. 
3. Insufficient insulation measures
First of all, we have to determine whether the next wall has insulation. We can judge by gently tapping the wall. If the sound is empty after tapping, it indicates that the wall has insulation. If the sound is dull, it indicates that the wall is not made of insulation. If there is insulation layer, it is necessary to check whether there is any crack in the external wall of the building. If there is no crack, it means that the insulation material is not acceptable and it needs to be replaced. This is the method of radical treatment.
4. Replace waterproof interior wall paint
