There are 6 reasons why you must use base film for wallpaper

One reason: anti-mildew, anti-humid

The main cause of mildew in wallpaper is due to the long-term treatment of the wallpaper in a humid environment. By painting the base film on the wall surface, an effective protective film is formed on the wall surface, so that the water inside the wall does not penetrate into the wallpaper coating layer, and the possibility of mildew in the wallpaper is reduced.

Reason two: Isolate the wall containing alkalis

At present, the domestic putty powder has a relatively high pH, ​​and is generally alkaline. When wallpaper is directly applied to a wall with high alkalinity, wallpaper discoloration and the like may occur within a period of time after the wallpaper is attached. This phenomenon is commonly called “burning paper”. If alkali-resistant base film is used, the wall pH will be effectively reduced and a protective film will be formed on the wall to effectively isolate the alkali content of the wall.

Reason 3: Curing the wall to prevent wallpaper from falling off

Because most of the surface of the wall is rough and uneven, and the surface is easy to drop powder, if the wallpaper is glued directly on the wallpaper, the adhesive force of the wallpaper glue will not be sufficient, which will reduce the adhesion effect of the wallpaper, and the wallpaper will fall off easily.

During the renovation process, a large amount of dust, sewage, etc. will be generated, which will easily cause minor stains on the walls. After the base film is used, a white film is formed on the wall surface to cover all the stains. After the wallpaper is applied, the stain will not appear on the wall surface.

Reason 5: To protect the wall for easy construction

After the base film is used, the wall surface is solidified and the wall surface is more even. When the wallpaper is applied, the wall surface is flat and the wallpaper is convenient for moving the flowers. When the old wall is dismantled, the wall will not be damaged and the wall will always be in good condition. When the wallpaper is replaced with new wallpaper, it can be directly constructed without re-treating the wall.

Reason 6: Safety and environmental protection of water-based raw materials

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

The main processing steps of the wallpaper:

1. Ensure that the moisture content of the base layer of the wall is below 8% - 10%.

2, in the putty touch flat before the base should be solid, can not have pan-alkali, empty drums, crisp and so on.
