What is the function of basement membrane wall stickers?

Wall base film is a cationic water-based acrylic emulsion with sealing and curing properties. After brushing on the loose base, it can greatly improve the hardness and adhesion of the base, and has the characteristics of high hardness, water resistance, mildew resistance, permeability, alkali resistance and vomiting resistance. The use of wall base film: it can seal and strengthen the base layer, improve the adhesion of the base layer, and prevent the coating from hollowing and falling off. As a wall treatment material, the basement membrane mainly plays the role of waterproof, moisture-proof, leveling, reinforcement and wall protection. According to the different characteristics of the floor and the wall, the targeted selection of basement membrane products will effectively extend the use time of the wallpaper and provide protection for the effect of the wallpaper on the wall.

One step in pasting wall stickers and wall skins is to apply a basement membrane. The function of the base film is alkali resistance, moisture resistance, mildew resistance, curing and protecting the surface of the putty.

We in the wall putty dry, polished smooth, smooth, wall floating ash clean, and then brush the base film.

The base film coating process is relatively a decorative and concealed process, so it is not standardized. Wall stickers and wall stickers are hard to find in a short time after pasting. Therefore, many renovation contractors are not interested in this, they perfunctory. I see they don't even brush the basement membrane.

The following are the walls that must be treated with silo basement membrane when pasting wallpaper5A reason.

Reason1: Anti-mildew and anti-moisture

The main reason for the moldy wall stickers is that the wall stickers are in a humid environment for a long time.

By coating the base film on the wall, an effective protective film is formed on the wall, so that the water in the wall will not penetrate into the wallpaper adhesive layer, reducing the possibility of moldy wallpaper.

Reason2: Alkali substances in the wall

At present, our country putty powderpHThe value is higher, generally alkaline. When the wall stickers are directly attached to the high alkaline wall, the wall stickers will change color within a period of time, which is commonly known as "burning paper" phenomenon.

If an alkali-resistant membrane is used, it will effectively reduce the wall'spHValue, and form a protective film on the wall to effectively isolate the alkali content of the wall.

Reason3: Cure walls to prevent wall stickers from falling off

Because most of the walls are rough and uneven, the surface is easy to drop powder. If the wall sticker is directly pasted, the adhesion of the wall sticker to the wall is insufficient, which will reduce the bonding effect of the wall sticker and the wall sticker will easily fall off.

After using the base film, one is to make the wall flat, cured and powder-free, and the second is that the surface of the base film has a certain adhesion, so that the wallpaper is not easy to fall off.

Reason4: Protect walls to facilitate construction

After using the base film, the wall will solidify more tightly and the wall will be more flat. During the construction of wallpaper, the wall surface should be flat to facilitate the movement of wallpaper. When the old wall is removed, the wall will not be destroyed and the wall will always be in good condition. After replacing the wallpaper, the construction can be carried out directly without wall treatment.

Reason5: Safety and environmental protection of water-based raw materials

The main component of the base film is acrylic acid, which is water-soluble and belongs to water-soluble materials. Compared with varnish, it is safer and more environmentally friendly.
