In addition, we should always open windows in our homes for ventilation.

Causes of moisture in the walls.

1. The temperature difference between indoor and outdoor is large. The first situation may be that 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 condenses to the wall, which will lead to the dampness of the wall for more than a long time. If you are not sure if it is caused by the quality of wall insulation, there is a very simple inspection method, you can try it at home:

Tap the wall with an inspection hammer and listen for the sound, if the sound is dull, it means that the wall is not well insulated.

Conversely, if the sound is hollow, it means that the wall is insulated. Of course, poor selection of insulation materials will also cause the wall to be damp, then it depends on whether there are cracks in the wall, if there are cracks, you can consider replacing the insulation materials.

2. If the water supply pipes and drainage pipes leak, the owners in the northern region should also pay attention to checking the heating pipes of their homes. Leakage in pipes can also lead to dampness and mold in the walls over time. You can ask a professional to do a suppression test to detect.

The root causes of mildew are: 1. The waterproofing of the exterior wall is not done well, and the water seepage. 2. The room is humid, and the moisture penetrates into the putty layer. 3. Improper selection of putty materials, ordinary putty is not waterproof and easy to mold.

It is best to do another layer of waterproof and stain-resistant treatment on the topcoat, which can effectively isolate the wall from the indoor environment, and the exterior wall will never be damp.

First remove the putty and re-use the water-resistant putty to make a leveling layer, then brush a layer of primer, two layers of paint, and finally use Xuanhe Jun glaze stain-resistant paint, brush or barrel on the old wall first, half an hour after the first coating is dry, and then brush again, the surface anti-fouling layer has been done.
