What if there is a lot of water in the wallpaper in the south wind?

Will wallpaper have a problem when it meets the south wind? The master, who has many years of experience in home improvement, said that problems such as mildew, bulging and falling off often have nothing to do with the quality of the wallpaper itself, and are often caused by improper handling of the wall base. Therefore, the first step in pasting wallpaper is to deal with the wall and lay a good foundation.

The substrate needs to be flat and dry. It is understood that wallpaper has high requirements for the basic treatment of walls. First of all, it is best to use putty powder of well-known brands as construction materials, and the ash layer recognized by putty powder is firm, waterproof and moisture-proof; Secondly, the polished wall should be smooth, clean, hard, dry, without cracks and holes, and the wall should be sealed with basement membrane or varnish. Sticking to this wall base, the wallpaper will be strong and not easy to fall off. Pay attention to the pattern of paving to be neat. The master told the reporter that the cut wallpaper can be pasted on the wall after being coated with glue. "The first picture is the most important, so that it can be horizontal and vertical, and the edge of the wallpaper matches the corner. In addition, the wallpaper should be pasted from the conspicuous end of the wall. For example, a wall with a door should start with the door. "

In the process of paving wallpaper, workers carefully compare the patterns on the wallpaper to make them consistent and neat; Wipe off the spilled glue with a clean towel in time to prevent the wallpaper from yellowing in the future; When there is a socket, cut an opening to facilitate the installation of the panel later. The pattern of the pasted wallpaper is neat, closely connected with the decorative lines, and the angle of yin and yang is vertical. From 1.5 meters away, you can hardly see the flat seam. Accessories should pay attention to environmental protection. Before pasting wallpaper, it is not light yellow varnish (varnish) that is brushed on the wall, but a colorless and tasteless basement membrane; Wallpaper glue is no longer wallpaper glue and white latex, but wallpaper glue is directly mixed with water. If you follow these two procedures, there will be no smell in the room. It is understood that varnish and basement membrane can play the role of sealing the wall, waterproof and moisture-proof, but in contrast, varnish has a faint taste, while basement membrane is colorless and tasteless, which is more environmentally friendly. The wallpaper glue for home improvement is extracted from potatoes and glutinous rice, which is naturally healthier.
