Papering Around External Corners
There are many other areas where precise measuring, cutting and trimming are required. In most cases, it is simply a further application of the principles demonstrated on those pages. In others, however, some special techniques are needed; the most common of these are illustrated here. As always, remember to turn off the electricity before working around lights and switches, and drain radiators if removing them from the wall.
Hang the paper so that it bends around the corner (Image 1). Slice the bottom to make two separate flaps, then brush the paper flat.
Hang a second sheet around the corner. Make sure it is vertical. Check that the pattern fits, then brush the second sheet flat (Image 2). Overlap the first sheet.
Use a straight edge (a metal ruler is ideal) to cut through both layers of the overlap (Image 3).
Pull back the overlap and remove the paper below. Then remove the excess from the top sheet. Smooth to reveal a precise butt joint (Image 4).
Trim the top and bottom of both sheets in the usual way. Remove any excess paste from the paper surface. Use a roller to secure the seam (Image 5). You are now ready to hang the next sheet.
