What should I do if I do internal and external insulation, but the wall is still hairy?????

1) Shovel off the wall skin and brush with waterproof and breathable putty.

2) Do waterproofing. Find out the seepage point. Treated with waterproof material. Small seepage points can be made with glass glue.

3) Do insulation. Increase the warmth of the wall. Prevent the intrusion of cold air.

You can also use anti-mold wallpaper: anti-mold wallpaper is chemically treated, which excludes the phenomenon of mold, foaming, and mildew breeding when the wallpaper is humid or when the temperature difference between indoor and outdoor is large, and the surface is soft and breathable.

Of course, you can go to the home improvement market to find some emerging moisture-proof materials to use.

Be careful to stop putting water or wet things on the side of the wall).

It depends on whether you are in the south or the north, the two are opposite, the south, back to the south can not open the window, the northern winter due to the low temperature outside the outside and high inside, plus the humidity exhaled by someone in the bedroom, the indoor air temperature is high and contains water vapor, and there will be water condensation in the walls and windows with low temperature, so you should open a small window crack to reduce the temperature difference, the premise is not to frostbite, hehe! Try it and find out! More information, better advice.

The overall insulation and waterproofness have been broken, so it is recommended not only to do insulation, but also to redo the waterproofing.

If you look at the previous company, you can't have a say without an investigation.

Hot flashes indoors, enhanced ventilation.

Before making interior wall paint, you should do an anti-mildew primer once.

There are a variety of factors that contribute to moldy and hairy wallsEspecially in the cold weather area in the north, the temperature difference between indoor and outdoor is large, and the cold air enters the house and combines with the hot air to form a water mist adsorbed on the wall, which will cause the house to be damp and mildew.

This kind"Cold bridges"The phenomenon generally occurs in columns, ring beams and other structures; It is easy to cause leakage, facing peeling, moldy hair and other phenomena. Avoid"Cold bridges"phenomenon of the problem, building insulation is very important. It is directly related to the quality of insulation construction technology and materials, and the quality of insulation materials will directly affect the insulation effect of buildings.

In the architectural design, the wall material is not made of blocks, but directly made of concrete, which is also prone to condensation. If you exclude factors such as leakage of exterior walls, bathroom walls and pipes in rainy days, moldy and hairy walls in winter have a certain relationship with the destruction of the insulation layer.

The exterior wall is well insulated and can effectively isolate the moisture outside.
