There is a wide range of so-called. spray wallpapers. They are a kind of thin-layer plaster, applied to the wall with a spray gun. We prepare the wallpaper in a stainless vessel, by mixing the liquid binding agent with the so-called. filler. After applying the wallpaper to the wall, the filler creates a spatial texture of the surface. Various types of silk or cellulose dust are used as a filler, sand and mica. The latter creates shiny walls on the surface, mirror spots.
