With the improvement of people’s living standards, the level of decoration has also been greatly improved. The risks of improper home waterproofing treatment have been widely known, so people are paying more and more attention to the waterproofing and moisture-proof treatment of home decoration. However, many families often have no way to start due to lack of sufficient investigation, especially the residents on the first floor who are more worried. I often see similar news on the Internet: after residents on the first floor adopt common kitchen and bathroom waterproofing treatments, they often still have discoloration of the walls and mold on the decorative materials, which is puzzling. What should be done with the first floor? Leibangshi combines many years of practical experience to tell you in detail. 1. Observe knowledge First, we must understand the main aspects of home waterproofing. Simply put, home waterproofing should include protection against open water and waterproof gas, that is, against liquid water and gaseous water. Waterproofing is what we often call and are familiar with as kitchen and bathroom waterproofing. It is mainly used in bathrooms and kitchens to apply waterproof coatings to achieve the effect of blocking water. It is dealt with in ordinary households; while waterproofing gas is to prevent the moisture caused by the evaporation of liquid water. The air seeps into the building structure and then escapes out. It corrodes over a long period of time and causes moisture, causing discoloration of the decorative surface, mold, etc. This is what the waterproofing system calls "moisture-proof". This is two different things from what we often call "moisture return". Do not confuse them. For a altar. 2. Analyze the reasons. Then, to understand how the first floor is different from other floors, we analyze it from the origin of water. In addition to the open water generated when the kitchen and bathroom are used, for the first floor, especially for houses without underground overhead floors, there is a lot of moisture below the ground due to rain corrosion and groundwater. If the ground is not waterproof and moisture-proof, Moisture will emerge and corrode flooring, carpets and other materials on the ground; also, the entire building wall is a whole, and moisture will "flow" in it. Because the moisture is heavier, it will sink, so it often sinks on the first floor. Accumulation will increase the "load" of the wall on the first floor. Furthermore, because the first floor is low, there is generally less sunshine and poor ventilation. The water vapor remaining in the building evaporates slowly, making it difficult for the wall to dry out during decoration, which also creates a problem. One of the reasons why the building is damp. 3. Solution Therefore, in view of the special situation on the first floor, when we carry out waterproofing treatment in the home, in addition to waterproofing treatment in the kitchen and bathroom, we should also carry out specific isolation of water vapor and moisture from various channels: that is, in addition to the bathroom In addition to coating the kitchen and the kitchen with waterproofing, all the floors and walls on the first floor should be treated with moisture-proofing. The usual method is to paint the entire surface with polymer cement-based waterproof slurry, and then perform finishing construction, so that the entire house is covered with moisture-proof coatings. "Raincoat" is naturally full of confidence.
