Whether art paint is environmentally friendly depends on its composition and its price. Generally, mural pigments commonly used in the market include gouache, acrylic pigment, pigment, wall paint and so on. Most of the murals in Tibet use mineral natural pigments-very environmentally friendly but not cheap. The price depends on the grade of materials used. Good paint costs 600-700 per square meter, but the price difference is very low.

I decorated it with wallpaper several times. I wonder if the wallpaper on the market is so unreliable. Anyway, I feel that the smell of chemicals is quite strong, which is probably not good for people's health. When using wallpaper, be careful about its quality. The price is generally 59- 100 per square meter.

Diatom mud has been introduced for several years, and the slogan is environmental protection. It is not used much in the projects I supervise, about 180-260 per square meter, because of the price problem and its decoration often need to be displayed in a large area. Generally speaking, the housing area for family use should be at least 98 square meters for public decoration.
