"Liquid wallpaper" is called green environmental protection coating, because it does not need to use 107 glue, polyvinyl alcohol, etc. In the process of construction, it does not contain heavy metals such as lead and mercury and aldehydes, thus achieving non-toxicity and pollution-free. Because it is a water-based coating, "liquid wallpaper" has strong anti-pollution ability, good moisture-proof and antibacterial properties, and is not easy to be moth-eaten and aging. Different styles of patterns can be made on the wall through special molds. This product is mainly made of the surface layer of natural shellfish biological shell, and the adhesive is also a non-toxic and harmless organic colloid, which is a real natural environmental protection product. Wallpaper coating not only overcomes the shortcomings of single color of latex paint, non-delamination, easy discoloration, curling, foaming and short service life of wallpaper, but also has the advantages of easy construction, long service life, exquisite wallpaper pattern and good decorative effect. It is a high-tech product integrating the advantages of latex paint and wallpaper.
