Outsmarting Bull Nosed / Rounded Edges / Arch

Looks nice, huh?

But these rounded edges , especially arches , have been a thorn in the side of wallpaper installer s since they became popular more than 10 years ago. Hanging paper on them and trimming neatly at the right point is difficult. Because the paper is hanging over the edge blocking your view of where you need to trim . A level or laser level don’t always work because the home’s framing isn’t always perfectly plumb . Metal straightedges / trim guides are useful, but can slip and mess up your cut. The arches present their own challenges because a straight edge won’t line up with them .

A colleague in the Wallcovering Installers Association ( WIA ) invented this gadget , which is a huge help. This is a 1.5″ section cut off from the 10′ length of bull nose corner bead used in the drywall construction of these edges. Then you cut notches in it at the point on the corner where you want to trim your wallpaper .

Some installers place a trimmer blade in the notch and slide the gadget along the edge, trimming as they go. I find that the thing wobbles too much for an accurate trim, plus it’s difficult to hold the blade while you’re sliding the thing down the wall. So I put a pencil point into the notch and draw a line along where I want to trim. Then I can use a straightedge and trimming blade , or a scissors, to cut along the line. Makes a nice, even, straight cut! Note that I like to wrap it about 1/3 of the way around the rounded edge.

OK, so you’ve seen how I trimmed along the edge to the right. Now here’s another trick that I’m going to use on the edge to the left, as seen in the photo. The wallpaper strip is 20.5″ wide. But I trimmed it vertically so that the piece over the arch is 10″ wide. That correlates to the point where I want to trim the strip that will land on the rounded edge going down the wall.
Note that I have not completely trimmed the part under the arch on the left side, because I want to be sure the cut edge lines up with that on the next strip I’m going to hang.
The blue plastic tape is there to keep paste off the wall paint . It will be removed after the piece is trimmed to fit.

Now here I’ve placed the remaining 10.5″ wide left section of the strip of wallpaper. You can see how it’s falling perfectly along the bull-nosed edge – saving me from having to use a blade or straightedge or gadget.
Note that this works only if the edge is perfectly plumb , and that the piece above the arch is also perfectly plumb, and my new strip is hanging perfectly plumb. This paper is a non-woven material, and is somewhat stiff and unbending , so not really amenable to twisting or tweaking into place. Plus, you want to keep that left edge straight, because your next / subsequent strip will need to butt up against it. Trust me, I did a lot of measuring and shooting the laser level before I pasted or hung any paper!
Now that it’s in place, I can go back and trim that remaining bit under the arch, making sure that it meets up in the corner with the edge of this piece .

Here’s another shot of it finished.

This tree branch foliage pattern is called Twining and is by Graham & Brown . I like most everything they make. The non-woven substrate is designed to strip off the wall easily and in one piece , with no damage to the wall , when it’s time to redecorate .

Using One Strip to Cover Two Areas Saves Wallpaper

This wallpaper is 20″ wide . My next strip to the left needs to be 20″ wide above the window – but only 1.5″ wide down the side of the window. I hate to use a whole 6′ long strip for this area. Because, as you can see, most of the strip will be where the window is, and will be cut off and thrown away.

But here’s a plan. The same thing is happening on the right side of the wall, on the window to the right. About 10″ of the wallpaper has extended over the window, leaving about 10″ of the lower portion to be cut off and thrown into the trash.
NNo! Since I need a 1.5″ width of a right edge to finish my area on the left side of the wall (see previous photo), I can use this discarded lower 10″ of wallpaper to cover that 1.5″ to the left.

Planning ahead and measuring carefully, I removed the lower section of wallpaper that would have been hanging over the window / shutters . I left plenty of overlap to allow for trimming along the top and along side the window molding. Added bonus – because I’m now not wrestling a 20″ wide strip of paper next to this window and shutters, it keeps a lot of paste from slopping onto the window molding and shutters .
zin this photo, you see the 10″ wide strip I’ve removed. And also the 1.5″ wide strip from the left right edge, that will be put against the strip to the left.

Here’s my 1.5″ wide strip.

And here’s where I’m going to put it. Note that I cut a short strip to fit over the window . It’s 20″ wide – the width of the roll of wallpaper . I cut it long enough to come down the side of the window to where there’s a design element – in this case, a horizontal branch – to disguise the juncture of these two pieces of wallpaper .

About to go into place .

Positioned. Note the overlap of the branch, trimmed along the lines of the motif. This makes the overlap way less noticeable than a straight horizontal patch, or even a splice.
Note: I don’t like to splice / double cut in situations like these – cuts into the wall surface below and can cause the paper to come away from the wall. I don’t mind overlaps in these situations. They’re up high where no one can see, and also much stronger and more stable than a butted edge .

Teimming off excess along the window molding / trim .

Doone!

The tree and leaf pattern is called Twining and is by Graham and Brown . Like most of their materials, it’s a non-woven material and can be installed by pasting the wall – although I usually paste the paper . It is designed to strip off the wall easily and in one piece when it’s time to redecorate . The seams are invisible .
