What is the harm of moldy walls?？Moldy walls emit mold spores. The mold spores will flow into the air and enter the body to invade the respiratory system.

If the human body is exposed to mold for a long time, it can cause respiratory conditions and allergic conditions.

4. If the family immunity is very low, it can cause headache, fever, or mucosal inflammation and serious carcinogens.

1. Most of the mold on the wall is due to the heavier moisture in the southern air, and when it encounters the surface of a cold object, it is coalesced, resulting in water droplets. It is prone to mold when water vapor adheres to and wets the surface of the wall paint film for a long time, which usually occurs on roofs, vignetting, etc.

2. The mold of the wall may also be due to the poor quality of the paint used on the wall, and the antibacterial and anti-mildew properties of the paint are insufficient. Water vapor can easily penetrate walls, causing mold growth.

1. Minor treatment.

If there is only a little mildew on the wall, use a cloth with mold remover, solvent bleach, disinfectant, etc., or use a small spray, then clean, wait 24 hours, and wipe with a cloth with a little water.

2. Serious governance.

If the wall has severe mildew, you can remove the surface with sandpaper or remove it with a razor blade, then spray some bleach on the wall, coat it with a filler after it is completely dry, apply an anti-mildew alkali or sealing base, and finally apply an anti-mildew topcoat.

The reason for the mold on the wall: because the waterproofing of the wall is not done well, the pipe in the wall is leaking, and after a long time, it has been in a wet situation of water seepage, and the water seeps into the wall, which will cause the wall to seep. The temperature difference between the house and the outdoors is large, and the wall insulation is not very good, especially when the season changes, the front will be damp, causing water seepage on the wall.

It is very likely that when the house is decorated, the workers are shoddy, and the bricks of the wall are not tightly embedded and not filled with the bottom of the wall, which will cause the wall to be built but not rounded and have gaps. After a long time, it is easy to seep water into the wall and reverse moisture. It is very likely that there will be some problems in the structure of the house itself, which will make the water and moisture in the body unable to be discharged, and over time, there will be dampness and mildew.

Especially in the humid summer, the water seepage in the house will be more serious.

Post-treatment of mold on the wall: When decorating, it is necessary to clarify the structure of the house, and before moving in, find a professional staff to test the environmental humidity of the house. Be sure to buy a regular wallpaper mold remover, so in the spring and summer when it is very easy to grow mold, an appropriate amount of paint can also effectively prevent and solve the mold situation.

In the rainy season, we must close the doors and windows in time, and when the temperature is good, we must timely indoor ventilation and maintain indoor air convection, which can also effectively maintain the humidity and temperature in the environment and prevent dampness and mildew. If the economic development conditions are available, a dehumidification function equipment can be configured at home, so that it can effectively dehumidify and prevent mildew.

If there are black spots due to water seepage on the wall, you can use a rag to remove the mold in time to prevent the growth of germs. Then spray it with bleach, or change the paint to paint the wall again. For serious mold wall decoration, use sandpaper and ash knife to completely remove the mildew spots, and then replace the mold remover, 84 disinfectant or bleach solution to spray the wall; Repair and level the wall with putty powder, and the long-term wet and cold wall should be waterproofed on the ground (the leakage of the wall should be searched and repaired before); After the putty layer is dried, the closed topcoat and mildew removal thickened alkali primer are painted; Paint to remove mildew paint.

There are two reasons why there is mold on the wall. One is external, i.e., weather or man-made, and the other is internal, i.e., the wall itself.

1. External causes: The so-called external causes refer to excessive air humidity; The rainy season or return to the south is when the air humidity is relatively high, and the moisture in the air will meet the cold wall to form small water droplets, just like what we take out of the refrigerator, which is the reason why there is a layer of water outside. As a result, the small droplets of water that accumulate on the walls will penetrate into the paint film on the walls for a long time, resulting in the formation of mold on the walls.

There are three areas in your home that are most prone to mold, namely the ceiling, the area near the water, and the dark corner. Mold is more likely to occur when ventilation is poor or when the temperature is low.

2. Internal reasons: there is moisture inside the wall or the quality of the wall coating is not closed; The antibacterial or antifungal resistance of the coating product itself is relatively poor, and water vapor is easy to penetrate into the inner layer of the wall, so that there will be a lot of mold coming out. If there are some workers who do not operate properly during the construction process, it is easy to cause mold in the paint film, such as the construction when the paint is excessively diluted and the humidity is too high.

1.Structural factors: Most buildings are frame structures, the walls are covered with walls, the joints between the walls and the beams and columns are prone to cracks, they are the weak links of insulation and waterproofing, filtered water in summer, and overcooled in winter.

The thermal insulation effect of the wall is not good, resulting in a large temperature difference between indoor and outdoor, and the water in the indoor air will condense on the wall when it is cooled, which is the partition wall wet.

2.Construction factors: exterior wall bricks are not embedded, joints of bricks are not full or joints are used, exterior walls are not filled with mortar, there are trachoma, depressions, cold bridges are formed (hot), joints of walls and beams and columns are not densely filled, when installing doors and windows, cracks appear and foam filling is not dense and gaps.

These causes are susceptible to moisture and water absorption, resulting inThe walls of my house are going to be moldy

3. Environmental factors: the wall is cool, the indoor temperature is high, and it is easy to condense. The thermal insulation effect of the exterior wall itself is not good, so that the wall is cool, the wall is cold, and the indoor water vapor crystallizes in the water droplets on the wall, which will be causedThe walls of my house are going to be moldy

4. Domestic factors: in the process of life, do not pay attention to ventilation, indoor air circulation is not smooth, indoor humidity is too large, and damp walls are easy to adhere to the nutrients floating in the air indoors, molds; Indoor air, which contains nutrients, is a floating material that adheres to the walls and is prone to mold.

If the walls are dry, the decoration will be closed. moisture will be enclosed in the walls, which will also make:The walls of my house are going to be moldy, and use poor interior materials. Molds can also be produced at a certain temperature and humidity.

3. External rainwater.

External rainwater infiltrates the room, causing the wall to be damp, and cracks in the baffle under the balcony window (mostly made of prefabricated floor slabs, so it is easy to crack at the junction with the wall) and the wall, or the window has poor sealing performance, which may cause the external rainwater to seep into the room.
