Betcha Can’t Find The Kill Point

December 9, 2020

Usually, when hanging wallpaper, you start in a corner, work your way around the room, and end up on the opposite side of that same corner. This virtually always ends up in a pattern mis-match. So we try to place this in an inconspicuous place, such as in a corner behind a door.

But this powder room didn’t have any hidden corners. All four of the corners were very visible to anyone in the room. I didn’t want an 8′ high corner of half-flowers and mis-matched motifs.

So I decided to put this kill point in the least noticeable space – the 1′ area above the door.

As you can see in the top photo, when the last strip of wallpaper came to meet up with the first strip, the pattern wasn’t going to match.

I didn’t want to have flowers cut abruptly in half vertically. So I decided to do some double cutting – a paperhangers’ term for splicing.

By cutting along the flowers in the design, I knew I could prevent an abruptly cut off flower. I padded behind the strips to protect the wall from being scored. Then I overlapped the new strip onto the first strip.

Then I took a sharp new razor blade and used it to cut along the motifs, pressing hard enough to cut through two layers of paper – but not cut into the padding and definintely not into the wall behind it all.

Once the excess paper was removed and the strips smoothed back into place, the seam is flat and smooth, and you could never tell that the designs is a marriage of two sets of motifs.

Shrinking Flowers to Get a Good Kill Point

April 5, 2019

As you hang wallpaper around a room, the pattern in the last corner will end in a mis-match, because the motifs on that last strip won’t match with those on the first strip. So you try to hide that kill point in an inconspicuous place, such as behind a door.

But this large dining room didn’t have any hidden corners. So we were likely to have a 6′ long corner of flowers that didn’t match one another.

But over the entry arch was an area only one foot high. Since this was very short compared to the other full-length walls, and since it was an area that was not going to be viewed much, it was a better place to put this kill point.

So I hung paper on the walls on the left side of the arch, then on the right side, and prepared to have strips meet at the center over the arch. When the strips met there was going to be a flower motif that repeated itself before the normal pattern repeat rhythm. In other words, there were going to be two flowers too close to each other, with one of them being chopped off abruptly at about 1/3.

After pondering different solutions, I figured that if each flower were a bit narrower, that 1/3 bit of excess could be eliminated.

I tested two different methods of “shrinking” the flowers. First, I tried cutting through the flowers vertically, then overlapping a little. This made the flower motifs narrower. See third and fourth photos.

In the second method, I cut around the right outside edge of the flower motifs, and again overlapped. This reduced the spacing between flowers. It did crowd the motifs next to the others a bit more than I liked. And the cut, being made in an unprinted area of the wallpaper, was a bit more noticeable than that made in the printed area in the first option.

I decided on the first option. Cutting through the middle of the flowers resulted in a less visible pattern mis-match, left the spacing between motifs as the artist designed it, and left less of a noticeable ridge at the point of the overlap.

In the second photo, you can barely see that some of the flowers are narrower than others. This looks a whole heck of a lot better than having a flower-and-a-half-flower next to each other over the arch.

Double-cutting (splicing) these areas would have resulted in perfectly flat joins. However, I chose to overlap instead, because this area was up so high and was only about 30″ wide, with no side lighting, that no one is going to notice any ridges from the overlapped areas. More important, I don’t like double-cutting because it almost always scores the wall, and once the paper dries and shrinks and pulls taught, that can lead to the paper pulling the layers of wall apart, leaving gaps that cannot be glued back down. Overlapping won’t allow the wall to delaminate, and it results in a much stronger join.

This pattern is called “Indian Flower,” and is by Jasper Wallcoverings.

Trimming Grasscloth Inside a Curved Arch / Working Clean

As a follow-up to yesterday’s post, here is how I trimmed the stiff, rectangular grasscloth to fit the arched top of the bookcase back. You see slits in the excess paper, which we call “relief cuts,” that allow enough ease that the paper can be tucked against the wall, and then trimmed with my razor knife.

The blue stuff is a trick I used to keep paste off the painted areas around the bookcase. This is nice because it saves having to wipe the paste off. It is also important, because with grasscloth, you can’t get any paste or water on the surface of the paper, because it will leave a stain. So even wiping paste off the woodwork with a damp cloth, which is commonly done with most wallpapers, could cause water from the cloth to get onto the grasscloth and stain the natural material.

The blue stuff is a special 2″ wide thin plastic tape, invented and sold by a colleague who is also a member of the Wallcovering Installers Association (WIA). The tape has other uses, like to keep paste off the flat paint on ceilings, and when overlapping and splicing (double cutting) strips of wallpaper.

Protecting the Wall While Double Cutting – What Is This Funny Plastic Strip?

January 13, 2015

We call this strip of clear polycarbonate plastic a “Boggess strip,” after the last name of the guy (a member of the Wallcovering Installers Association, as am I ) who invented it. It is flexible and somewhat hard, and we use it to cut on, to protect the surface underneath.

Before I got a basswood board table, which you can directly on, I would put one of these strips on my table to protect it from cuts from the razor blade when hand-trimming wallpaper. But mostly we use the Boggess strips when cutting on the wall (double cutting – a type of splice). When cutting through two layers of paper, it’s tricky to know how much pressure to use, to get through both sheets of paper, but not score the wall. It’s really important to not cut into the wall, because, as wallpaper dries, it shrinks a little, and that shrinkage will put tension on the wall, and that tension can cause the surface of the wall to pull away, causing gaping seams, or even curling edges.

Putting one of the plastic strips underneath the seam before cutting will prevent that.

It’s a bit of a juggling act, all these layers of plastic and paper, and you have to move quickly before one strip or the other starts to dry, and then you’ve got to clean the paste off the plastic strip before you use it again.

It’s an invaluable invention, and I’m glad I have a roll of it in my toolbox.
