What should I do if my walls are moldy?

The causes of water seepage and mildew in the walls are:

1. There is no insulation layer on the wall: in the past, the wall of many houses did not have an insulation layer, in winter, the temperature difference between the surface and the inside of the room was large, so the wall was cold outside and hot inside, and the inner wall surface would produce condensation because of the high temperature, resulting in the wall being wet, and it was the whole wall, such a situation was usually only presented in winter, and it would be good in summer, but the sequelae was that it would leave a lot of ugly mildew, which would affect the beauty of the wall.

2. Leakage of water pipes in the wall: The leakage of the embedded water pipes in the wall caused by the lack of good connection of water pipes, the use of inferior water pipes, and the lack of pressure test of water pipes is easy to cause water seepage in the wall, which mostly occurs near the bathroom, the roof of the house or the wall.

3. Waterproof measures are not done: the wall waterproofing of the neighbor's bathroom next door is not done, the ground waterproofing of the upstairs neighbor's bathroom is not done, the waterproofing of the combination of the upstairs water pipe and the ground is not done, and the waterproofing of the roof or wall and ground is not done, etc., which may lead to the occurrence of leakage.

4. There are cracks or holes in the structure of the house: there are cracks in the structure of the house, there are gaps between the windows and the structure, and the air-conditioning holes are not tightly sealed, and the rainwater will seep into the wall along the cracks under the action of the wind, and the water vapor contained in the wall for a long time cannot evaporate in time, and the wall will become moldy.

Solve the root cause of water seepage first, and the rest will be easy to deal with, otherwise, if you deal with the moldy place, if the water leakage is not solved, it will become moldy again. Once the water seepage problem is solved, it is time to remove the mold with a special wall mold remover and spray it on the area where the mold grows.

4. If it is due to weather conditions, you need to shovel off the wall skin first, then paint the impermeable liquid, and then apply a layer of latex paint with good waterproofness. The reasons for this situation: 1. If the wall is moldy, it may be because the rainwater seeps into the home, and it is in the rainy season or continuous rain, then the cracks in the wall will have rainwater infiltrating into the room, which will lead to dampness around the window, and there will be various mildew stains, which seriously affects the aesthetics and practicability.

2. There will be many materials used in decoration, and the materials contain nutrients, and there will be cellulose when the wall is scraped white, which is sugary, and there may be mold breeding under the appropriate temperature and humidity. If you use a poor quality one, the wall will definitely not appear moldy. 3. There may be moisture in the wall that is sealed, it may be that the wall stucco has not dried and the decoration has begun, and the moisture is sealed in the wall, which will make the wall mildew or even hairy, which will have a great impact on the wall.

4. It may be that the waterproof layer has been destroyed, and there is a leakage problem on the top layer, then the roof of the shed will be moldy and hairy, and if the waterproof layer is destroyed during decoration, it will begin to leak, and even the bottom layer will have moldy problems.

If the surface of the wall is moldy, you can use a dry brush or dry rag to remove the mildew on the wall, otherwise it will easily lead to more serious mildew on the wall.

If the wall insulation is not done well, it will lead to cold penetration, and the phenomenon of cold penetration is mold, blackening, and hair growth on the indoor wall. The reason is that the indoor air is warm, the water vapor saturation is high, and the wall is not well insulated due to the cracking, 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.

To avoid the hair of the wall, the main thing is to do a good job of wall insulation.

2. If the water seepage on the wall is due to the leakage of the water pipe, the water pipe needs to be replaced immediately, or the special repair glue for the water pipe should be used to repair it first. First of all, after closing the valve and cutting off the water source, open the faucet to the appropriate position to release the pressure in the water pipe, and tie the leaking part with special adhesive tape, or seal it with the plugging king.

CF-2000 high-efficiency composite waterproofing agent (cement-based permeable crystalline type) can be treated on both interior and exterior walls, and can be waterproofed by scraping like putty or plastering like putty on the wall or leakage parts, and scraping 5 mm thick.
