Narrow Strip Coming Out of a Corner

August 28, 2018


See that narrow 3/8″ wide strip of wallpaper sitting on my table? That is to be my first piece coming out of this corner.

When you hang wallpaper around an inside corner, you don’t wrap it around the turn, but, rather, split the piece vertically so it wraps 1/16″ around the corner. Then the strip that you cut off is hung on the next wall, butted up into the corner. This avoids twists and wrinkles and bubbled areas caused by walls and corners that are not perfectly straight or plumb.

But when the piece that is to be the first strip on the new wall is this narrow, it presents problems, because it’s very likely to not hang straight, and you can’t hang the next strip of wallpaper against a crooked edge because you will get gaps and overlaps.

Adding to the dilemma is that this narrow strip had already been pasted. I had finished for the day, and intended to hang the window wall to the left the next day. The strip was already pasted, but I couldn’t hang it because of the aforementioned issues, plus, you are supposed to hang a whole wall at a time, because all of the strips have to “meld” together – you can’t hang a wet piece against a dry piece.

My solution was to wash the paste off this narrow strip, and hang it up to dry overnight. I just had to hope that the water would not cause it to expand too much, or warp, or other.

The next day, I pasted this narrow 3/8″ wide strip, along with the strip that would be placed next to it. Then I hung them together, as if they were all one piece of wallpaper. That way, I could work them into the corner snugly, and keep the seam between them nice and tight.

When coming out of corners, it’s common for the wallpaper to go off-plumb, because the corner might be out of wack. So you can (barely) see the red line of my laser level on the left edge of the strip of wallpaper, ensuring that the new strip falls plumb.

Difficult Grasscloth Install Today

Boy, oh boy, today’s installation was a bear! To begin with, I had a 12′ high accent wall that required using my 8′ ladder, which is unwieldy and can push you away from where you want to work. The wall had a thick texture (typical in new homes in the Houston suburbs – this was near Cypress), that took hours to smooth, dry, sand, and prime.

When it was time to hang the paper, I pasted and booked (folded pasted side to pasted side) and prepared to trim a bit off each edge, which is pretty standard procedure for grass, plus I had planned to trim all the strips to 34.5″, which would make all the strips the same width, which is nice with grass since all the seams are quite visible. I got one seam that looked great. But there was some warping in the material, but I was able to smooth it out.

But when I tried to trim the next strip, the folded edges did not line up, no matter how many times I rebooked it. If the edges don’t line up perfectly, you will not get a straight cut. I dicked around with it for a while, but eventually had to get the strip on the wall, or it would become unusable – and we did not have even one extra strip.

I decided to use the factory edge and leave the strip it’s full width, which was going to screw up my balanced widths of 34.5″. I soon learned that unequal widths of strips was one of the least of my woes that day…

The paper backing had absorbed moisture from the paste, and the whole strip had warped out of shape. No way would the edge butt up perfectly against the previous strip. In the end, I got most of the strip butted and smoothed, but the bottom 1′ or so insisted on overlapping onto the previous strip, so I took a straightedge and very sharp razor blade and cut away the overlap.

This turned out to set the mood for the rest of the job. All the subsequent strips warped significantly, not matter how long or short I booked them. No way would the seams butt up. So I ended up overlapping all the seams and double cutting – the industry term for splicing.

This is not as simple as it sounds, though. For one thing, the newly smoothed wall was soft, and you don’t want to cut into it, or when the paper dries and shrinks a little, the torque it creates can actually pull the wall surface apart, resulting in a curled seam that cannot be pasted back.

So I ran out to my truck and got some special polystyrene strips that are 2″ wide and are placed behind the seam, to protect the wall from the cut. I also grabbed a really nice straightedge that is made just for this purpose, with a handle and a non-slip surface. And some blue plastic tape, because I had to protect the bottom layer of grasscloth from the paste on the strip that was to be overlapped on top of it during the double cut. This is important, because any paste that gets on the surface will stain grasscloth – you have to work absolutely clean.

All three of these special items, by the way, were invented by fellow paperhangers, and fellow members of the Wallpaper Installers Association.

Positioning all these materials took a lot of time. Making the cut itself was intricate, because I could get a good position on it for only a foot or so, then would have to climb down and move the ladder over a little, so I could get right in front of the next couple of feet as I worked my way down the 12′ high strip. Also, two layers of grasscloth are quite thick, and it takes a lot of pressure to do so – while trying not to push myself away from the wall and onto the floor. And you only get one chance to cut, because multiple swipes result in a jagged and ugly seam.

Once the cut was finished, I had to go back and remove the two excess pieces, and the polystyrene strip, and the blue plastic tape, all the while making sure that no paste got onto the surface of the paper. Finally I could take my tool and smooth the two edges together. Double cutting does make a beautiful and perfectly butted seam. But, boy, it sure does take a lot of time, effort, and you need the right equipment.

Including prep and installation, this one accent wall with just six single rolls of grasscloth took me a full 12 hours.

So the seams were nicely butted. But, as you see in the photo, the grasscloth displayed the typical color variations that I find so displeasing. We call it shading and paneling. In the top photo, you can clearly see a difference in color between the two strips, even though they are from the same batch. The second photo shows a little more of this. The third photo is dark, but if you look closely, you can see three strips (two seams), and the slightly darker area along one edge, which is quite noticeable because it butts up against the next strip which is lighter in color.

All reasons why I dislike real grasscloth. The faux products are much more uniform, and seams can be invisible.

In addition, this is a pretty finely textured grass, and on a large, tall wall like this in a large room, I really don’t think the texture shows up very much, unless you are standing right at the wall.
