Ways to identify wallpaper environmental protection: 1, fire method - judging environmental protection and materials. If the store says that our wallpaper is made of natural materials, then you need a small piece of wallpaper in front of the store. After going home, the lighter burns, the natural material is basically smoke-free after burning, like burning paper or burning cotton; there is no pungent smell, no black smoke, the ash is gray powder, not a black coke Object. Regardless of what the store says about cotton, linen, bamboo, and paper, this method is applicable and effective. And if it is very pungent after burning, it also means that the pollution of the material is absolutely unusable, no matter how cheap, white does not. 2, soaking water method - the method of judging quality. Wallpapers are definitely more durable than latex paints, but the quality of wallpapers sold by many stores is not flattering. The best thing is to cut a piece and soak it. After 12 hours, if the wallpaper does not appear layered, the part of the side is not layered; there is no fading; it is basically qualified. Because of the water-resistant wallpaper, it will be drummed, degummed, etc. after damp.
