What are the causes of mold on the walls? What are the causes of mold on the wall?

The phenomenon of mold on the wall is not strange to us in the south! The landlord's primer must not have been brushed. The main problem is that the wall insulation is not done well, which leads to cold penetration, and the phenomenon of cold penetration is mold, blackening and hairy on the indoor wall.

The reason is that the indoor air is warm and the water vapor saturation is high, and the wall is not well insulated, so the wall is cold, and the water vapor will crystallize into water droplets on the wall, and the wall will become moldy and hairy when it is wet. Generally speaking, the main reasons for mold on the wall are as follows: 1. The reason for the wall:

The most important thing is that the wall should be waterproof, do not let the wall get wet, or stick the wallpaper near the window, and also pay attention to waterproofing, the water, wind and sunlight in that place are more affected, and there will be the possibility of mildew if the wallpaper is not maintained. (Of course, this mainly refers to the fact that for general wallpaper, if it is very expensive, really imported high-quality wallpaper, this situation is very unlikely); Therefore, it is also recommended that you choose waterproof wallpaper. Most of the wallpapers on the market are now waterproof.

Including imported pure paper wallpaper, the surface has been treated by special technology; 2. There is another cause of mold, which we tend to ignore, that is, during the construction of wallpaper, if the glue is not completely dry, there is a large temperature difference between indoor and outdoor, and it is easy to cause wallpaper such as warping and bulging and mildew in the future because of the long-term existence of moisture and air in the wallpaper. Therefore, the room that has just been paved with wallpaper should close the doors and windows and dry them in the shade. After 3 days of wallpaper paving, you should use a damp towel to gently wipe off the remaining wallpaper glue at the seams of the wallpaper.

At this time, the whole room can be completely ventilated. This is related to the construction of wallpaper, and there is also the need not to soak the wallpaper in water before the wallpaper is pasted, otherwise it is easy to make the wallpaper mildew! 3. Caused by high humidity in the environment.

This is mainly seen in the south. The reason for the rainy season. There are even most people who think that southern weather like Hainan in Guangdong should not be wallpapered.

Actually, as long as we pay attention to the ventilation of the room and avoid the rainy season to put wallpaper. The above is some introduction to the causes of mold on the wall, I hope it will have a certain reference role for you! Generally speaking, opening windows for ventilation is the easiest way to solve the problem of wall mold, and creating ventilation after the operation is completed can make the effect of removing wall mold twice as effective.

1. Causes of mold on the wall.

Why is there a lot of mold on the walls in winter? Of course, the temperature difference between indoor and outdoor is relatively large, which can easily make the wall "condense", if it does not dry for a long time, mildew and hair will grow, and therefore the wall will become moldy.

Second, the treatment of mold on the wall.

1.When the mold on the wall is not severe, it can be wiped with a damp cloth or washed with water, or if it cannot be completely removed, it can also be cleaned with bleach to remove the mold.

If you live in a moldy room for a long time, it is easy to be infected with germs, and over time, symptoms such as respiratory discomfort and general fatigue will appear, which is a great safety threat to the human body.

1. The temperature difference between indoor and outdoor is large.

The wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, and the water vapor in the indoor air is pre-condensed to the wall, which will cause the wall to be damp for more than a long time.

2. Leakage occurs in water supply pipes and drainage pipes.

Leakage in pipes can also lead to dampness and mold in the walls over time. The water pipe pressure test is one of the common methods to judge whether the water pipe connection is reliable, if the pressure test fails, it can indicate that there is a leak at a certain point of the pressure pipe.

3. Do a good job of waterproof and moisture-proof on the wall.

After cleaning the mold on the wall, you can apply a layer of waterproof paint to the wall, which can prevent the wall from becoming moldy again. There is also the need to open windows at home from time to time for ventilation.

Answer: Hello, your question is being sorted out, please wait a while, wait patiently, oh 1, the pipe in the wall is leaking, the wall is not waterproof enough, for a long time, water penetrating through the wall will cause mold on the wall. 2. There is a gap between the window frame, window sill and wall of the window part, or the sealing of the window is not good enough, resulting in rainwater entering the room, resulting in moisture and mildew on the inner wall, and insufficient insulation outside the wall.

The change of seasons can also lead to temperature differences, which can cause dampness on the walls.

Dear, hello, please give a thumbs up with your rich little hands, and wish you good health and all the best.

Causes of mold on the wall:

1.Rainwater seeps in.

During the rainy season or rainy days, rainwater enters the room through cracks in the walls, causing dampness around the windows, and mildew will appear over time.

2.Insufficient insulation of exterior walls.

If the insulation layer of the wall is not done well, it is easy to appear that the wall is cold and cold, and the water vapor in the house will become water droplets, and the wall will be easy to be damp and mildew.

3.Waterproof is not good.

If the waterproofing of the ceiling surface is not done well, there will be water leakage and mold.

4.Environmental factors.

Usually, if we don't pay attention to ventilation when we live, the indoor humidity will be too large, and the wall will be easy to get wet, resulting in moldy on the wall. In addition, the summer time in the south is long, the air humidity is high, and the air in the coastal areas is humid, so the wall is also prone to mold during the rainy season in the south.

Solution: Use a professional wall mold remover. It has the effect of mildew prevention and mildew removal, and it can be restored as long as it is sprayed on the moldy place for 30 minutes. The most important thing is that it is non-toxic and harmless. Save money, effort and time;

1. The mold of the wall is due to the dampness of the room, and people are prone to rheumatism when they live in this environment for a long time.

2. The moldy wall will emit mold spores, which flow in the air and enter the human body to invade the respiratory system and multiply rapidly. Long-term exposure to mold can cause respiratory diseases and allergic symptoms.

3. People with low immunity may also cause headaches, fever, or mucosal inflammation, and in severe cases, carcinogens will be produced.
