Wallpapering Inside Corners

1 MEASURE DISTANCE BETWEEN THE CORNER AND THE LAST STRIP ON THE WALL. These steps are designed to eliminate sloping paper caused by out-of-plumb corners. Measure in three places— from the edge of the previous strip to the corner at the top, middle, and bottom of the wall.

2 ALIGN THE EDGES OF THE BOOKED STRIP. Add one-half to 2 inches to the widest distance measured in Step 1. Mark that measurement at both folds of the booked strip. Hold a straightedge that is at least as long as the folded strip against the marks. Guide a razor knife against it to cut the strip to width. Save the cutoff.

3 POSITION THE STRIP ON THE WALL SO THAT THE PATTERN MATCHES THE PREVIOUS STRIP AND OVERLAPS THE CEILING BY ABOUT 2 INCHES. Align the edges so they butt against each other, and let any extra width go around the corner onto the next wall.

4 USING OPEN PALMS (and clean hands], GENTLYSMOOTH THE PAPER onto the walls and into the corner.

5 MAKE SLITS FROM THE CORNER TO THE EDGE OF THE PAPER at the top and bottom of the strip so that you can wrap the overlap around the corner without any wrinkles.

6 FLATTEN THE STRIP WITH A SMOOTHING TOOL. Trim the excess at the ceiling and baseboard. Be careful not to squish the glue out from behind the wallpaper by pressing too hard.

7 MEASURE THE WIDTH OF THE CUTOFF FROM STEP 2. Measure this distance from the corner onto the unpapered wall and make a pencil mark. Draw a plumb line through this mark from ceiling to floor, guided by a level.

8 HANG THE CUTOFF ON THE WALL, WITH THE CUT EDGE TOWARD THE CORNER AND THE FACTORY EDGE AGAINST THE PLUMB LINE. Align the pattern, overlapping the two pieces as necessary. Press the strip flat with a smoothing tool. Trim at the ceiling and baseboard.

9 IF USING VINYL WALLPAPER, PEEL BACK THE EDGE AND APPLY VINYL-TO-VINYL ADHESIVE TO ANY PAPER THAT OVERLAPS. Press the seam area flat. Let the strips stand for half an hour, or as directed on the package, and then roll the seams. Rinse excess paste off with a damp sponge.

Wallpapering Outside Corners

1 DRAW A GUIDE LINE. If the corner is out of plumb, the edge of paper you wrap around it will also be out of plumb. Lay out a plumb line that you can use as a guide. Start by measuring from the existing strip to the corner at the top, bottom and middle of the wall. Add V2 inch to the longest distance and subtract the total from a the width of a strip of paper. Draw a line this distance from the corner.

2 MEASURE THE WIDTH OF THE CUTOFF. Draw a plumb line on the wall that is this distance from the cut edge of the previous strip. Hang the cutoff. Align the leading edge with the plumb line, and smooth the paper against the wall. Slide the paper to match the pattern, overlapping the previous strip as necessary.

3 CUT THE PAPER AT THE TOP AND BOTTOM USING WALLPAPER SCISSORS so you can wrap it smoothly around the corner.

Wallpapering around windows and doors

Think of window and door openings as simply larger electrical outlets. Paper over them, at least in part, and then cut off the waste. Hang the strip as you normally would, right over the window or door casing. (A common mistake made when hanging wallpaper is to precut the strips to “fit” the shape of the windows and doors. Given Murphy’s Law and the tendency of wallpaper to stretch, this inevitably fails.) Use a smoothing tool to smooth the strip before trimming the edges. Wipe any excess adhesive off casings with a wet sponge.

BE STRIP WISE - If you're hanging short strips directly above and below an opening, draw a plumb line with your level to mark where the leading edge meets the wall. This helps to ensure a good pattern match with the full strip at the edge of the opening. Don't trim the short strips until you've hung the full strips and made sure they're plumb too. Leaving them long lets you jockey them into the correct position without creating gaps.

CLEANUP TIPS - Paperhangers aren't perfect, but the good ones have mastered a few tricks that make them look like they are:

• Club soda will break down dried glue without damaging the paper.

• If you have bubbles under the paper, smooth them toward seams. Don't cut the bubble unless the glue is dry.

• Use clean water and change it frequently.

• Wipe excess glue from ceilings, cornices, and baseboard moldings before it dries or it will cause the paint to lift off the surface.

1 PRIME AND SEAL THE WALLS. Position the strip on the wall, letting it cover the window or door casing. Butt the seam carefully against the edge of the previous strip. Smooth the flat areas of wallpaper with a smoothing tool. Press the strip tightly against the ceiling.

2 HOLD YOUR FINGER AT THE CORNER OF THE TRIM and cut diagonally toward it with wallpaper scissors. If you're hanging the paper around a window, make a similar cut in the bottom corner.

3 PUSH THE PAPER TIGHT AGAINST THE TRIM with a wallpaper knife or flexible smoother.

4 USE WALLPAPER SCISSORS TO TRIM EXCESS WALLPAPER to within about 1 inch of the outside edge of the window frame. Smooth the wallpaper and any bubbles as you work.

Wallpapering a recessed window

1 HANG A STRIP OVER THE OPENING FOR THE WINDOW AS IF THE OPENING WEREN’T THERE. Make two horizontal cuts—one slightly above the top of the opening, the other slightly above the bottom. Fold the flap formed by the cuts against the side walls of the recess. Fold the remaining paper over to form a flap on the sill and on the recessed wall above the window. Measure 2 inches to the right of the corner of the recess, and make a cut straight up and down from it to the ceiling. Remove paper at right of the cut.

2 CUT A STRIP LONG ENOUGH TO REACH FROM THE CEILING AROUND THE TOP EDGE OF THE RECESS AND TO OVERLAP THE WINDOW SLIGHTLY. Always make your cuts with a clean, fresh blade. Starting at the ceiling, hang the strip so it overlaps the entire width of the first strip. Align your straightedge with the edge of the window and cut along it to the corner of the opening. Fold the paper around the top edge of the recess and smooth it in place. Repeat below the window, as shown.

3 YOU’RE ABOUT TO MAKE WHAT PAPERHANGERS CALL A“DOUBLE CUT,” A PROCESS LESS FRIGHTENING THAN IT SOUNDS. Align a straightedge with the left-hand edge of the recess. Cut along the edge, cutting through both layers of paper. Pull off the scrap to the left of the cut. Peel back the right-hand strip, and remove any paper underneath it. Put the right-hand strip back in place, smooth it, and roll the seam. Repeat below the window.

4 IF THE REMAINING UNPAPERED SPACE ABOVE THE RECESS IS MORE THAN ONE STRIP WIDE, hang the next strip, wrapping the paper around the top edge of the recess and across the upper recessed wall, trimming it at the window. Repeat below the window.

5 POSITION THE NEXT STRIP SO THAT IT OVERLAPS THE PREVIOUS STRIPS COMPLETELY and hangs from ceiling to floor. Cut vertically at the edge of the recess and fold the flap against the recess above the window and at the sill.

6 ALIGN A STRAIGHTEDGE WITH THE EDGE OF THE RECESS AND DOUBLE-CUT BY GUIDING A KNIFE ALONG IT. Peel back the top layer of paper as necessary to remove any scrap underneath.

Wallpapering inside an archway

1 APPLY WALLPAPER ON BOTH SIDES OF THE ARCHWAY with strips hanging over the opening. Smooth the strips and trim the excess at the ceiling and baseboard.

2 USE WALLPAPER SCISSORS TO TRIM THE WALLPAPER in the archway to about 1 inch below the arch. Use vinyl-to-vinyl adhesive with vinyl and vinyl-coated wallpapers.

3 MAKE SLITS IN THE WALLPAPER ALONG THE CURVED PORTION OF THE ARCHWAY, cutting as close as possible to the wall edge. Cut carefully to avoid snipping into paper that will be covering the wall of the arch. The steeper the arch, the more slits you'll need to make.

4 WRAP THE CUT EDGES INSIDE THE ARCHWAY AND PRESS FLAT. If the adjacent room is being wallpapered, wrap the wallpaper around the edge of the archway from both sides.

5 MEASURE THE WIDTH OF THE ARCHWAY AND CUT A STRIP TO COVER IT FROM THE PAPER YOU’RE USING. The strip should be 1A inch narrower than the inside surface of the archway.

6 COAT THE BACK OF THE ARCHWAY STRIP WITH VINYL-TO-VINYL ADHESIVE. Position the strip along the inside of the archway with a Vs-inch space on each edge of the strip. Smooth the strip with a smoothing brush and rinse with a damp sponge.
