Before applying the wallpaper, you need to treat the wall, namely organize a layer of oil paint based on organic solvents or, as an option, cover the surface with alkyd primer. If the wall is ready, then you need to pull out a slightly viscous mixture mixture from a bucket with liquid wallpaper and simply attach this lump to the wall (this process feels like a wet paper attach to the wall). Immediately begin to roll out a lump of liquid wallpaper attached to the wall with a spatula. The peculiarity of applying liquid wallpapers is that you can create any pattern, carrying out the rolling process. The consistency is heterogeneous, so moving the tool, you will create unusual textures.
