Begin to stick a strip of wallpaper from the upper edge. The whole process must be carried out evenly and gradually. On the outside, the wallpaper is pressed with a rag. It should be clean and dry. It is drawn from top to bottom, as well as from the middle of the canvas of the wallpaper to its edges. It is necessary to ensure that bubbles and cracks do not appear. You can’t press a rag to the wallpaper hard. Otherwise, the initial pattern may be lost.
