What is the reason for the high moisture regain of the wall?

The walls of the house will be damp, moldy and damaged if they live for a long time. If it is not handled in time, the longer it is delayed, the more serious the problem will be. So what are the causes and treatment methods of wall resurgence?

First, the reason of wall moisture regain

The root of moisture regain lies in the generation of water vapor. Where does the water vapor come from? Finding the source of water vapor can solve the problem of moisture regain.

1, the waterproof layer of the external wall of the building is damaged, causing water seepage in the building. If this is the reason leading to the resurgence of the wall, it is necessary to contact the property or developer to comprehensively improve the waterproofing of the external wall of the building. Water seepage on the external wall of buildings is particularly obvious after rain and snow, which is a big problem that owners can't solve by themselves.

2. The daily splash between the kitchen and bathroom causes the wall to be wet. This situation is a common cause of wall resurgence. Especially the wall under the kitchen cabinet and bathroom cabinet is more likely to happen. This is caused by splashing water along the kitchen cabinet wall when washing vegetables and dishes. It is suggested that glass glue should be filled at the joints between kitchen cabinets and bathroom cabinets and walls to stop the water flow, so that the wall moisture regain phenomenon can disappear.

3, the bathroom is not waterproof, which is caused by wetting the wall. Generally, this situation often happens when the bathroom is rebuilt with light walls. 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.

Second, the wall moisture regain treatment method

1, when the outside humidity is high, close the doors and windows to prevent moisture. Usually, more windows should be opened for ventilation to reduce the indoor water vapor content. Especially in newly renovated houses, the water vapor is particularly strong, and more ventilation is needed to eradicate moisture.

2. Use air conditioning to dehumidify. Air conditioners used at home generally have the function of dehumidification. However, the method of air conditioning dispatching indoor air humidity is slow, which usually takes two or three hours, and it will make people feel very cold indoors.

3. Buy an air dehumidifier. Just like a vacuum cleaner, it can gather moist air together and turn it into water when there is a lot of water.

4, the room is humid, you can use a single dose and activated carbon to prevent moisture and moisture absorption. Both single dose and activated carbon are acceptable. There are many single distributors specially used for moisture prevention and dehumidification in supermarkets. The most common are moisture absorption boxes and dehumidification bags.

5. Dehumidify with lime and bamboo charcoal. Fill a small cloth bag with appropriate lime, tie it into a small bag and put it in every corner of the room. Lime itself has the function of moisture absorption and can also slow down the indoor humidity. At the same time, lime also has the function of disinfection, killing two birds with one stone. Bamboo charcoal dehumidification can be reused, but it takes more, and the useless effect is not so good.

6. Wash frequently. Finally, it is usually necessary to clean the room frequently, and humidification is mainly preventive. Do more cleaning, clean the corners and walls, so as to delay the dampness. Wet places should be scrubbed with dry cloth.
