Turning an Inside Corner With Wallpaper

When bringing wallpaper around an inside corner in a room, you virtually never should wrap a full sheet around the corner.

That’s because corners are never absolutely straight, walls are never perfectly plumb, wet wallpaper stretches and twists… Coming out of the corner, the outer edge of the paper will never be straight, so the next strip won’t butt up properly. And the strip could be thrown off-plumb, meaning that the design will start tracking up or down the wall. Oh, and you will probably get wrinkles and warps, too.

To prevent all this, you split the strip in two vertically, and allow just 1/16″ or 1/8″ to wrap around the corner. See top photo. This tiny bit of wrap is important, because, if you cut exactly into the corner, you would end up with a visible cut edge, plus gaps in the corner.

Your next strip is then overlapped on top of this narrow wrapped edge, as shown in the second photo.

Note that when you do this, you will cover up and lose some of the design.

To minimize this, I have my clients buy a little extra paper. Then I can use a fresh sheet to split vertically, while matching the pattern as perfectly as possible. Yes, it uses more paper and costs a bit more … but for a visually seamless transition from one wall to the next, that you will be enjoying for the next many years, it is a good pay-off.

This new strip that gets overlapped and hung coming out of the corner … It is important that it be hung plumb. Because if it’s not, then all subsequent strips will fall more and more off-track.

In the last photo, I am using the red line of my laser level to ensure that the right edge of this new wallpaper strip is perfectly level.

Often, this means you have to “adjust” the strip in the corner … and that often means that you will have to trim off some, in order to get it to lie nice and tight in the corner. And, yes, that means losing a bit more of the design.

This is inside corners, pretty much in a nutshell. Of course, there are a lot more details and nuances not covered here.
