What about the wall moisture regain? Experts suggest the causes and treatment methods of wall resurgence.

What should I do if the wall is wet? The resurgence of the wall is the most worrying thing for many families. Many people will find black spots on the wall when they are wet after decoration, or there is water leakage on the top and wall, which leads to the resurgence of the wall. A large part of the reason for high indoor humidity is related to indoor ventilation. Various phenomena bring a lot of inconvenience to family life, but many people don't know what causes it and how to check it. What about the resurgence of indoor walls? What are the causes and treatment methods of wall resurgence? Don't worry, now I will share with you the treatment method of wall resurgence!

Causes 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. There are three reasons for wall moisture regain:

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.

The bathroom is not waterproof well, which is caused by wet walls.

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.

Daily splashing between the kitchen and bathroom causes the walls to be wet.

This situation is a common cause of wall resurgence. Especially the walls under kitchen cabinets and bathroom cabinets are more likely to happen. 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.

What should I do if the wall is wet?

1, using 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. The most common are moisture absorption boxes and dehumidification bags.

2. 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. 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 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.

4. When the external humidity is high, close the doors and windows.

Close the windows to prevent moisture, but usually open more windows 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, the use of air conditioning dehumidification

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.

6, protect the electrical shielding

When the indoor humidity is too high, if you don't need a computer or TV, you'd better 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.

7. Brush off the mold

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

8, bleaching powder spray

In addition, adding water to bleaching powder at the ratio of 1: 99, then pouring it into a spray bottle and spraying it on the moldy wall surface can also solve the problem of moldy wall surface. If the climate is still humid, bleach and water can be distributed according to the ratio of 1: 20 and smeared on the mold wall. After the wall is monotonous, smooth it with sandpaper, then brush a layer of waterproof primer, and finally brush a layer of latex paint.

9. 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, and scrub the damp parts with dry cloth.

Manufacture of household dehumidifying small objects

Pay attention to the small details in life, and we will find that life can actually be simple and happy. How much attention do you attach to these small problems? Pay attention from today, and your life will improve from tomorrow.

Dehumidifying small objects 1: self-made washing powder dehumidification box

At home, the most commonly used moisture-proof small object is the moisture-proof box, but it seems unrealistic to use the moisture-proof box bought in the supermarket in the bathroom. Actually, we can DIY one ourselves. The self-made moisture-proof box of washing powder can be said to be a good moisture-proof object in the bathroom. Because washing powder is a good dehumidifier, we can open a new boxed washing powder (or pour the old one into the used water absorption box), poke a few small holes in the plastic film and put it in any corner that needs dehumidification. Washing powder can be used to clean clothes after it is saturated and caked with water, and it will not be wasted.

Dehumidifying gadget 2: lime absorbent bag

Usually, you can also make a lime moisture-absorbing bag and put it in the bathroom to help the tiles prevent moisture, but you should pay attention to using quicklime instead of lime for construction. Take some quicklime powder, wrap it in a cotton cloth or cloth bag of moderate size, sew it, and hang the small cloth bag in a damp place with a rope.

Dehumidifying gadget 3: coffee grounds moisture absorption bag

Take out the used coffee grounds, dry them, put them in small bags, and tie them tightly with ropes. It can be hung on walls, corners and other places, and can also be placed in cabinets, which has a good moisture absorption effect.

Dehumidifying gadget 4: Waxed metal sanitary ware

Bathroom hardware sanitary ware needs to pay attention to daily moistureproof, and waxing sanitary ware is a good way to moistureproof and rust-proof. Take a small amount of car wax and dip it on the surface of hardware sanitary ware with a toothbrush and sponge, especially where it is easy to rust, such as the moving parts of sanitary ware. After being evenly smeared, it is like putting a moisture-proof protective suit on the sanitary ware, which has a more lubricating effect.

Dehumidifying gadget 5: Hanging desiccant

Bathroom hardware sanitary ware needs to pay attention to daily moistureproof, and waxing sanitary ware is a good way to moistureproof and rust-proof. Take a small amount of car wax and dip it on the surface of hardware sanitary ware with a toothbrush and sponge, especially where it is easy to rust, such as the moving parts of sanitary ware, and spread it evenly, just like there are many desiccants dedicated to moisture prevention and dehumidification in supermarkets today. The most common types are moisture absorption boxes and bags. Many water-absorbing boxes have various scents, such as lemon, lavender, sweet orange, etc., which can make the house full of scents and are suitable for being placed in living rooms, rooms, bathrooms, kitchens and other large spaces in daily life. After using it for a period of time, you can take out the substances in the moisture absorption box and buy bulk desiccant and put it in the box for reuse.

Dehumidification of small objects VI: instrumental method

Moisture-proof and dehumidification can also use scientific and technological means to mobilize all electrical appliances with dehumidification function in the home to reduce indoor air humidity. Nowadays, the air conditioners used in general families have the function of dehumidification. But it takes two or three hours to adjust the indoor air humidity with air conditioner, and it will make people feel very cold indoors. If you are not satisfied with the dehumidification effect of the air conditioner, you might as well go to the mall to buy special dehumidification equipment, which will be faster but consume more electricity. In addition, the heater used for heating in winter can also alleviate the indoor humidity to a certain extent, but the effective radiation range of the heater is small, which can not achieve immediate dehumidification effect.
