Having checked the vertical of the angle along the plumb line, starting from the wall with the window, the first cloth of wallpaper is glued. Subsequent cloths are glued with an overlap of the edges in the direction of the window, strictly withstanding the coincidence of the edges with the previously glued panel and the pattern on it. The glued panel is smoothed with a brush or rubber roller with movements from the middle to the edges of the panel and from top to bottom.
