How to make good use of moisture-proof when the wind is strong in the south

There are two kinds of questions asked by the landlord. If it is because the wall is wet, do a good job of moisture-proof treatment of the wall. If the water vapor in the atmosphere is heavy because of the climate, the landlord basically doesn't have to consider it. Anyway, no matter what materials are used, this problem will be encountered. As long as it is indoor dehumidification, some dehumidification products can be put indoors, and dehumidification equipment can also be installed. Of course, we should also pay attention to living habits. For example, in wet weather, the windward window is only opened during intermittent ventilation. Turn it off immediately after ventilation.

Knowledge related to moisture-proof treatment of ground walls:

Usually, the ground on the first floor, where the wall is 1 m high, the basement and warehouse floor must be moisture-proof. If it is a house with more than two floors, you can choose to do it, such as the floor and wall of the bathroom and kitchen.

General owners are very easy to confuse the concepts of moistureproof and waterproof, and often treat them equally, thinking that waterproof is moistureproof. This is a relatively wrong understanding. What we want to prevent moisture is moisture (that is, water vapor), and waterproof is mainly to prevent liquid water. The molecular density of waterproof layer can't stop water vapor. Therefore, moistureproof cannot be done in a waterproof way. Especially on the first floor, or houses with basements, moisture-proof treatment is still very important.

Moisture will bring us these troubles:

First, the underground water vapor will corrode our floor;

Secondly, in the season of ground moisture regain, the moisture content of indoor air will be seriously exceeded by underground moisture, and living in this humid environment will have an impact on our health.

The cement base of the ground and wall must be moistureproof, otherwise it will have no effect. And it needs to be moistureproof before waterproofing. This can prevent the waterproof layer from falling off and foaming. Moisture-proof needs to choose professional moisture-proof materials, not waterproof materials.

Moisture-proof materials must have these characteristics: first, they have permanent moisture-proof effect and are concealed works. If they fail after several years of use, there is no remedy. Second, it must be an environmentally friendly material and does not contain any volatiles. The whole floor of the house is moistureproof, and products with volatiles cannot be used. The volatile area is too large.

Here I recommend a special floor moistureproof liquid from America. The reasons for the proposal are:

First, it has a permanent moisture-proof function, which has the ability to resist underground water pressure and air pressure. The 20-30mm moisture-proof layer formed by its reaction with cement is permanent, and it is integrated with the cement base surface and will not fall off, blister or be damaged.

Second, it's all inorganic, without any volatiles and non-toxic.

Third, the construction is simple, as long as it is sprayed twice on the original cement floor and wall. The construction period is short, you can walk in one hour after the construction, and the next working procedure can be carried out in 72 hours.

Fourth, the cost is low, and the cost per square meter is about 15 yuan.
