How to prepare a wall for wallpaper gluing

Before you start gluing new wallpaper, clean the wall from the old. To do this, use the roller, after moistening it in hot water. Given the fact that the walls often differ in height, it is necessary to leave several extra centimeters when cutting the paintings, which after the wallpaper are dried up, cut off with an acute knife. Depending on the type of wallpaper, the glue is applied either to the canvas itself, or directly on the wall. In order to decide on the type of glue, carefully read the instructions for working with the wallpaper.
