Which is more important, wallpaper glue or basement membrane?
At present, most of the adhesives on the market are starch food glue, glutinous rice glue and potato glue. Relatively speaking, glutinous rice glue has stronger viscosity, longer service life and more environmental protection. Glutinous rice glue takes pure natural rice as the basic raw material, and is carefully developed with international cutting-edge technology. Suitable for pasting all kinds of wallpaper and wall cloth. At the same time, it also has the properties of mildew resistance, bacteriostasis and cold resistance. It is an ideal adhesive for high-end raw materials such as environmental protection wallpaper and wall cloth.
The function of basement membrane is to dry and solidify the wall surface, and the wall surface with putty powder is powdery, so the adhesion is very weak when pasting wallpaper. The important function of basement membrane is to harden the wall surface, at the same time avoid preventing the wall surface from being wet and maintain the wallpaper. The wallpaper base film is a new kind of raw material to solve the wall problem when wall covering is pasted. Before pasting wallpaper, a layer of wallpaper basement membrane is coated on the wall, which can produce a high-density protective film on the wall, avoid the leakage of moisture and alkaline substances, reasonably prolong the service life of wallpaper, and facilitate the disassembly and replacement of wall covering afterwards.
How to remove the wallpaper glue left after tearing wallpaper?
1, the application of alcohol. As far as waterproof architectural coatings are concerned, cleaning wallpaper glue with alcohol can't cause too much damage to the wall, and it is often the release of alcohol that can greatly reduce the damage to the wall. But the concentration of alcohol must not be too high, otherwise the volatiles are too large, which will easily turn the pure white wall into light yellow or gray black.
2. If the wallpaper is torn off to make wall paint, it is suggested to remove it immediately and stick putty again to continue to make wall paint.
3. If it is torn and pasted again, it can be glued directly. Or you can tear off the wallpaper and roll warm water, and then scrape off the residual super glue on the wall, but it is easy to damage the wall when removing the residual super glue.
Step 4 add salt. In the process of rubbing, you can use pure white emery cloth or salt-resistant cloth to wrap a small bag of salt and rub it gently. Gradually, you will find that the super glue in the wallpaper left on the wall is slowly disappearing.
5, matte cloth. This method is very harmful to the wall paint, and it may grind the wall itself if you are not careful.
