It will do some harm to human body, because mildew is caused by humidity, that is, the indoor relative humidity is very high, so people will get rheumatism if they live in a humid environment for a long time.

In both cases, when it rains, the rain outside will penetrate into the cracks, causing the wall to be moldy. Therefore, if the wall is moldy due to cracks, it should be repaired in time.

The insulation of this wall is very poor.

Poor thermal insulation effect of the wall can also lead to mildew of the wall, especially in cold weather areas, where the temperature difference between indoor and outdoor is large and indoor water vapor is easy to generate. Coupled with the use of heating and air conditioning, indoor water vapor will condense on the wall, leading to mildew on the wall.

The lightweight partition wall in the bathroom must be waterproof, and the waterproof height must be 1.8 to 2 meters, instead of 30 centimeters as usual.

Otherwise, water vapor permeates into the lightweight wall through the tiles and is absorbed by the lightweight bricks. After a long time, it will soak the wall, making the wall without wall bricks on the other side damp and moldy. If this is the reason, it must be waterproof again.

3. The daily splash between the kitchen and bathroom causes the wall to be wet. This situation is a common cause of wall resurgence. This situation is more likely to happen on the wall under the kitchen cabinet and bathroom cabinet. This is caused by splashing water along the kitchen cabinet wall when washing vegetables and dishes.
