Introduction Hopefully, you have learned from our tutorials "Wallpaper Preparation" and "Wallpaper Basics" that wallpapering is, although a time-intensive task that requires focus, that it is also a fun job that beautifies a home. Those first two tutorials helped you through a room - now you're ready to go around corners and door and window openings.
When wallpapering, rounding corners and dealing with door and window openings is more complicated than simply laying strips across a flat wall. However, it is easier to employ a "Double Cutting" system and to understand that overlaps are necessary with your openings.
Unfortunately, you should keep in mind that in some older homes (and in some newer ones too!), there are rarely plumb corners as the house settles over time. This might have made your task harder since you can't depend on a plumb line for your corner. Double cutting your wallpaper (i.e. using overlaps) will help you negotiate these corners.
Skill Level & Time
• Beginner - 8 to 10 hours
• Intermediate - 6 to 8 hours
• Advanced - 4 to 6 hours
Cautions When removing receptacles and switch plates, be sure that you turn the power off in the room before you begin.
Rounding Corners. You will need to measure the vertical distance from your last strip of wallpaper to the next corner. Measure in two or three places to be sure your measurement is accurate. Cut your next strip an inch wider than this measurement using your utility knife and a straight edge.
Lay the strip down just as your previous strips and press the paper into the corner carefully so as not to tear the paper. Press it cleanly into the corner with a seam roller.
For the next strip of wallpaper, snap a plumb line onto the other wall - a distance of one inch short of your wallpaper's width from the corner.
Lay your second strip of wallpaper along this new plumb line. Again, tap the paper into the corner over the previous strip of wallpaper. Then, carefully smooth over the overlap with the seam roller.
Double cut through both thicknesses of wallpaper about ¼ inch from the corner and at the seam of the overlap.
Remove the outer piece of "extra" paper. This piece is called the selvage.
Lift up the outer paper just enough to get at the inside selvage. Remove this piece and lay the outer piece back onto the wall.
Smooth over the seam with your seam roller as you have done with the adjoining paper on your flat wall.
You should use the same double-cutting method for outside corners to keep your wallpaper plumb.
Papering Door and Window Openings. You will use many of the skills you have learned above to wallpaper around these openings. The basic gist is to line up an oversized strip as you have in your previous hangings. As shown, the strip of wallpaper should overlap the casing of your door or window.
Tap the wallpaper into the corner of the casing and crease it.
Using a straightedge cut the paper where the paper meets the casing.
Finally, trim your outlets and switches by cutting an X over them and trim to the edge of the outlet opening.
Your outlet or switch plate will hide any rough edges here. Allow all paper to dry before turning your electricity back on.
