1, wall foundation treatment. Before painting the liquid wallpaper, we must thoroughly remove the wall foundation. After the original wall skin is removed from the wall, the interface agent should be painted on the wall, mainly to reduce floating ash and enhance the adhesion of the wall itself. Then thoroughly level the wall surface, and the putty can be dried for three times before the construction of liquid wallpaper can be carried out.

2, mixed debugging wallpaper paint. Open the wallpaper paint selected in advance, fully stir it and let it stand for a period of time. The bubbles on the paint surface can be used only after they have completely dissipated. Pour the wallpaper paint after bubble dissipation into the previously selected pattern mold, and pay attention to the amount of paint poured each time to avoid splashing on the surrounding ground when using the roller brush later.

3. Liquid wallpaper should be painted correctly. We should draw wallpaper at reasonable fixed points according to the size and spacing of the selected wallpaper patterns to ensure that each pattern is vertical and parallel. If the width of the roller brush is not enough when brushing to the corner position, we can use a soft film brush to brush manually, which can ensure the flatness of the whole liquid wallpaper.

1, look at the brand

See if the brand is also applicable when buying liquid wallpaper. The brand will not only have a certain quality assurance, but also the problems after sale, and the problems can be replaced in time. Look at the brand also depends on the place of origin and production date, quality inspection report, are indispensable.

Step 2 look at the price

Cheap and not good, good quality liquid wallpaper is produced by regular manufacturers, and the raw materials are authentic, so the price is moderate. In order to pursue sales, those fake and shoddy manufacturers with poor quality often cut corners, reduce costs and sell at low prices. The quality of the products produced by this manufacturer is unreliable.

Step 3 look at water solubility

After the liquid wallpaper is left standing in water for a period of time, there will be precipitation, while the upper layer will have glue floating, and the normal qualified ratio is about 1:4. The color of glue solution is colorless or yellowish, and the water quality is clear. The glue of inferior liquid wallpaper is turbid and obviously presents the same color as the pattern color particles. The main problem is not that the stability of the paint is poor, or it has passed the storage period and is not suitable for use.

4. Look at the particle size

Take a clean and transparent glass, fill it with half a glass of water, then put a little liquid wallpaper into the water and mix it well with the water. Good quality liquid wallpaper, the water in the cup is still clear, and the particles are relatively independent and uniform in size in clear water. For poor quality liquid wallpaper, the water in the cup will become turbid immediately, and the particle size will be differentiated. A few large particles are papular, and most of them are fluffy fine particles.

5. Look at floating objects

Any liquid wallpaper with good quality has almost no floating objects on the surface of the glue, and a few colored particles are in a normal state. However, if there are too many floating objects and floating on the surface is too thick, it is an abnormal performance, then the quality of liquid wallpaper is very poor.
