How to use moisture-proofing when the water is strong in the south

The question asked by the poster has two situations. If it is because the wall is damp, just do moisture-proof treatment on the wall. If the water vapor in the atmosphere is heavy due to climate reasons, then the poster basically does not need to consider it. Anyway, no matter what materials are used, this problem will be encountered. As long as the dehumidification treatment is done indoors, you can place some desiccants indoors. products, dehumidification equipment can also be installed. Of course, you should also pay attention to your living habits. For example, in humid weather, the windows on the windward side should only be opened during intermittent ventilation. Close immediately after ventilation.

Relevant knowledge about moisture-proof treatment of floors and walls:

Usually the ground on the first floor, the wall 1 meter high, the basement, the warehouse floor, etc. must be treated with moisture-proof treatment. If it is above the second floor You can choose to do moisture-proof treatment on the floors and walls of your house, such as bathrooms and kitchens.

It is very easy for ordinary owners to confuse the concepts of moisture-proofing and waterproofing. They often regard moisture-proofing and waterproofing as the same, thinking that waterproofing means moisture-proofing. This is a relatively wrong understanding. What we need to protect against moisture is moisture (i.e. water vapor), while waterproofing mainly protects against liquid water. The molecular density of the waterproof layer cannot prevent water vapor. Therefore, moisture-proofing cannot be done by waterproofing. Especially for houses on the first floor or with basements, moisture-proofing is still very important.

Moisture will bring us these troubles:

1. The underground water vapor will corrode our floors;

2. During the ground return season, the underground water vapor will corrode our floors. Moisture can cause the moisture content of indoor air to seriously exceed the standard. Living in such a humid environment has an impact on our health.

Moisture-proofing must be done on the cement base surface of the floor and wall, otherwise it will be ineffective. And moisture-proofing needs to be done before waterproofing. This will prevent the waterproof layer from falling off and blistering. Moisture-proofing requires the use of professional moisture-proof materials, not waterproof materials.

Moisture-proof materials must have the following characteristics: 1. It has the effect of permanent moisture-proofing. This is a hidden project. If it fails after a few years of use, there is no way to repair it. Second, it must be environmentally friendly materials without any volatile matter. The entire floor of the home is moisture-proof, so products with volatile matter cannot be used because the volatile area is too large.

Here I recommend the special floor moisture-proof liquid from the United States. Reasons for recommendation:

1. It has permanent moisture-proof function. It has the ability to resist underground water pressure and air pressure. It works well with cement. The 20-30mm moisture-proof layer formed by the reaction is permanent. It is integrated with the cement base surface and will not fall off, bubble or be damaged.

2. It is entirely inorganic, has no volatile matter, and is non-toxic.

3. The construction is simple, just spray it twice on the original cement floor and wall. The construction period is short, you can walk within an hour after construction, and the next process can be carried out within 72 hours.

4. Low cost, costing about 15 yuan per square meter.
