Aug 16, 2020
The decoration of modern room, using wallpaper to decorate has become a trend. However, few people know about the construction of wallpaper rather than the key. In this process, the choice of base membrane is undoubtedly the most fundamental and important.
In China, the main defects of the wall include excessive alkalinity, insufficient putty layer, easy cracking and water seepage. After getting feedback from the wallpaper wall problems, 80% of the reasons for wallpaper shops and wallpaper designers are directly related to the improper treatment of the wall, and only 20% of the reasons come from the wallpaper itself and wallpaper glue.
Why do you need to brush the base film when pasting wallpaper
Basement membrane is a kind of technical product developed to make up for wall defects. It provides convenience for the construction of wallpaper and makes the decorative effect of wallpaper more perfect.
Six reasons for wallpaper base film
As a wall material, the basement membrane plays the role of waterproof, moisture-proof, leveling, reinforcement and protection of the wall. The selection of basement membrane products will effectively prolong the service life of wallpaper and provide guarantee for the back wall of wallpaper.
1、 Mildew proof and moisture proof
The main reason for wallpaper mildew is that wallpaper has been in humid environment for a long time. By coating the base film on the wall, the effective protective film is formed on the wall, so that the moisture in the wall does not penetrate into the wallpaper coating, and the possibility of the wallpaper mildew is reduced.
2、 Barrier alkaline substances
At present, the domestic pH putty powder is relatively high, generally alkaline. When the wallpaper is directly on the wall with high alkali, the wallpaper will appear color phenomenon after a period of time, commonly known as "burning" phenomenon. (some imported wallpapers have similar stamps on the back, causing chemical reactions, colors).
If the base membrane is used, the pH value of the wall can be effectively reduced, and a protective film can be formed on the wall to effectively isolate the alkali content of the wall.
3、 Solidified wall to prevent wallpaper from falling off
Because most of the wall surface is rough and uneven, and the surface is easy to drop powder. After the wallpaper is pasted directly on the wall, the adhesion force is not enough, the bonding effect of wallpaper will be reduced, and the wallpaper is easy to fall off. After using the base film, the wall should be smooth, solidified and free of powder. Second, the surface layer attached to the base film, so that the wallpaper is not easy to fall off.
4、 Build walls to beautify walls
In the process of decoration, there will be a lot of dust, sewage and so on, which is easy to cause slight stains on the wall. After using the base film, a film is formed on the wall to cover all stains. After the wallpaper, there will be no stain on the wallpaper.
5、 Wall protection is convenient for construction
After using the base film, the wall surface is denser and smoother. On paper, the wall is smooth and easy to carry. When the old wallpaper is removed, the wall will not be damaged and the wall will always be in good condition. After the new wallpaper is replaced, the construction can be carried out directly without removing the wall.
6、 Safety and environmental protection of water based raw materials
The main component of basement membrane is acrylic acid, which is water-soluble and belongs to water-soluble substance. Compared with varnish, it is safer and more environmentally friendly.
