What is the reason why the wall is wet? In daily life, we often encounter various problems, so we also need to find various effective and cost-effective tools or methods to solve the problems. The weather in the south is hot and humid, and it often rains. Let's share the reason why the wall is wet.

What is the reason for the damp wall? 1 What is the reason for the wet wall?

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. After rain and snow, the external wall of the building has obvious water seepage, which is a big problem that the owners themselves can't solve.

2, 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.

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. It is suggested that the joints between kitchen cabinets and bathroom cabinets and walls should be filled with glass glue to stop the water flow and the moisture regain of the walls will disappear.

How to deal with wet walls;

1, use dehumidifier. When the room is wet, you can use a single dose and activated carbon to prevent moisture and absorb moisture. Both single dose and activated carbon are acceptable. There are many single distributors specially used for moisture prevention and dehumidification in supermarkets, such as moisture absorption boxes and dehumidification bags.

2, buy an air dehumidifier, it is like a vacuum cleaner, it can gather moist air together, and if there is more moisture, it will become water. Dehumidify with air conditioner. 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. Dehumidify with lime and bamboo charcoal. Fill a small cloth bag with appropriate lime, tie it into a 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.

4. When the external humidity is high, doors and windows should be closed to prevent moisture and damp. Usually, more windows should be opened for ventilation to reduce indoor water vapor content. Especially in newly renovated houses, the humidity is particularly strong, and more ventilation is needed to eradicate the humidity.

5, buy an air dehumidifier, it is like a vacuum cleaner, it can gather moist air together, and if there is more moisture, it will become water.

6. 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.

7, when the external humidity is bigger, should close the doors and windows, prevent be affected with damp and be affected with damp. 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, so it is necessary to ventilate more and eradicate moisture.

8. When the indoor humidity is too high, if you don't need a computer or TV, you can make a protective cover to prevent the back of the electrical appliance from touching the humid air. These appliances should be turned on frequently, and the heat generated when the machine is running can effectively repel moisture.

9. When the indoor humidity is too high, it will cause mildew and long hair on the wet wall. When indoor mold spreads, it will have a negative impact on people's health, especially those who are allergic to skin.

10, when there is mold on the wall, you can brush off the mold stains with a dry toothbrush first. Then wipe it quietly with a soft cloth dipped in alcohol, which can make the wall monotonous and prevent mold from breeding.

What is the reason why the wall is wet? 2 Speaking of the reasons for the wet wall, the main reasons for the wet wall at present are: there is no insulation layer on the wall, the impervious layer on the external wall of the building is destroyed, the building filters water, the bathroom is not waterproof, and the wet wall causes the kitchen and bathroom to splash water on the underwater wall every day to make the wall wet. Please check the following details:

There is no insulation on the wall. Indoor hot air will condense in a humid environment when it meets a cold wall. If possible, add insulation walls. If not, you can apply waterproof paint to the wall. Use two-component oriental rainbow. Diluted and coated on the wall will have some influence.

The waterproof layer of the external wall of the building was damaged, resulting in water leakage in the building. If this is the reason for the resurgence of the wall, it is necessary to contact the real estate or developers to completely improve the waterproofing of the external wall of the building. The external walls of buildings are leaking, especially after rain and snow. This is a big problem that the owners can't solve by themselves.

The bathroom is not waterproof, resulting in wet walls. Usually, this situation often happens in the light of the bathroom wall. The partition wall used to illuminate the wall in the bathroom should be waterproof, and the waterproof height can only be 1. He is 8 to 2 meters tall.

It can only be done at a height of 30 cm. Otherwise, the water vapor is absorbed by the wall of the lamp body through the tiles and by the light bricks. Over time, the wall will be penetrated to the other side. Walls without brick walls are damp and moldy. If so, it must be waterproof again.

The walls between the kitchens are splashed with water every day, making them wet. This situation is a common cause of wall rebound, especially on the wall below kitchen cabinets and cabinets. This is the case. Usually, splashing water when washing vegetables and dishes is because the wet wall surface flows over the kitchen cabinet wall.

It is suggested to fill the joints between kitchen cabinets, bathroom cabinets and walls with glass glue to prevent water flow. The tidal phenomenon disappeared.

What is the reason why the wall is wet? What are the methods to prevent the wall from getting wet?

1, choose good decoration materials.

Owners must choose good decoration materials when decorating, and fundamentally avoid getting wet, including material performance, brand and quality. Take putty as an example. Because the climate in the south is humid, they must choose one with good water resistance, such as Meichao 800 series, which is also Meichao putty. It is forbidden to use 400 series in the south, otherwise it will be very easy to get wet.

2, pay attention to the construction technology

The construction steps of the wall are very complicated, and every step is very important. First of all, the wall base must be clean, without any impurities and moisture, and then leveling, that is, scraping putty, generally takes about 2-3 times. It should be noted that after the first pass is completed, it must be completely dried before the next step can be carried out, otherwise the water in the putty will not volatilize in time, and the inner wall will be easily wetted later, as will the primer and area.

First, the difference between wall moisture regain and water seepage

1, the former is definitely a natural phenomenon and there is no way to avoid it. This will happen in a certain season, or when the home is wet. The latter is man-made, either it was not handled well during the decoration or the workers cut corners during the construction.

2. The main reason for the former is that the temperature difference is relatively large. It may be warmer inside and colder outside, so water droplets will appear, which is a physical phenomenon. The reason for the latter is that it is not waterproof.

3. If it is the former, there will be a lot of water on the wall, which will be wet to the touch and the corner will be moldy. If it is the latter, the humidity must be very high, and water will even flow downwards.

Second, how to repair the wall after water seepage?

1, remember to check it carefully and see what the problem is. There should be a crack in the wall. Everyone should find this crack and take corresponding measures to repair it.

2. Clean up the cracked place, then put the waterproof glue in until it is full, and then wait for it to solidify. It's best to use a glue gun, so don't worry about spillage.

3. After the glue is completely solidified, you can brush a layer of waterproof paint on the surface, which can play the role of double protection, and similar situations will never happen again. Friends who really can't fix it can go to a professional for help.
