What s the deal with moldy walls? How to fix it?

Hello! This is caused by the cold of the wall, which is commonly known, but it is actually the reason why the wall insulation is not done well. You say whether the hairy wall is an exterior wall or a wall that is related to the outside world. If yes, that's basically the reason.

The wall insulation is not done well, it is a problem of building quality, in the north, a very important part of housing construction is the external wall insulation. In general, measures are taken in the north to carry out thermal insulation treatment, and the main method is to sandwich insulation materials in the wall. Block the conduction of heat by 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 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.

To avoid the hair of the wall, the main thing is to do a good job of wall insulation. But sometimes under the current technical conditions in our country, it is impossible to deal with it very, very well, if the indoor humidity is too large, even if the wall insulation meets the requirements, there will still be moldy and hairy phenomenon.

Therefore, if there is no serious problem with wall insulation, your best way is to open more windows to ventilate and reduce the indoor water vapor content, especially in the newly renovated house, the water vapor is particularly large, and you should let the air for a period of time to remove the moisture.

Sometimes the wall may be insulated, but the window will also have the phenomenon of cold and water, and the flow to the wall will also cause mold and hair, the reason is the same.

In short, if you are one: do a good job of insulation; 2. Reduce indoor humidity; Three: more ventilation indoors.

In terms of the quality of the house:

1) The construction quality and craftsmanship are poor, resulting in gaps between the doors and windows and the wall during installation, and the plastering is not full during the wall masonry, forming a cold (hot) bridge;

2) The insulation of the exterior wall itself is not done well, resulting in the cold of the wall, resulting in the cold of the wall, and the indoor water vapor will crystallize into water droplets on the wall, and the wall will become moldy and hairy when it is wet;

3) The wall waterproofing is not done well or there are leakage points in the pipeline, resulting in damp hairs.

Residents: (1) In the process of using the house, do not pay attention to ventilation, resulting in excessive indoor humidity, and the damp wall is easy to adhere to the floating matter containing nutrients in the indoor air and generate mold;

2) Decoration is carried out before the wall is dry, and the moisture is enclosed in the wall, which will also lead to moldy and hairy walls;

3) The use of inferior interior decoration materials, under a certain temperature and humidity, it is easy to produce mold.

It is because the moisture prevention at home is not done well, so it will cause the room to be very damp and the wall will be moldy. All moldy walls should be dug up and treated with moisture.

The mold of the wall is generally caused by the moisture in the air in the place, or it may be caused by water seepage and leakage from the outside of the wall or water pipes. After the wall is moldy, you can use a brush to brush off the mold and then wipe it with a damp rag. In severe cases, you can also wipe it with a cloth dipped in alcohol to speed up the drying of the wall.

Allow a month or two for damp walls to dry, and then replace the waterproof interior paint. In the future process, indoor ventilation should be strengthened, and dehumidifiers can also be used.

I hope my answer is helpful to you, and finally I wish you good health and happiness again!

Leaks in the drainage or heating pipes cause the walls to become damp, and over time, the walls will become moldy.

2. The wall insulation is not done.

The wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, so that the water in the indoor air will condense into the wall after being cold, resulting in dampness on the wall.

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.
