Clever Kill Point – Eliminating a Pattern Mis-Match, Damask Pattern

January 15, 2019

When you hang wallpaper around a room, usually starting in a corner, the pattern on your last strip will never perfectly match up with the pattern where you first started. So we try to hide this in the least conspicuous place – like behind a door.

But in this room, there were no “hidden corners” that would be obscured by a door. Since all four corners were very visible, I wanted them all to have their pattern match perfectly.

So I had to find another place put that “kill point,” – where the last piece meets up with the first piece. I decided to put that over the door, a 20″ high strip. I figured that would be less noticeable than a 7″ length in a visible corner.

Sorry, for some reason, my “before” photo disappeared; it was a shot of the gap over the door where the last strip was coming to meet the first strip.

In the top photo above, I have overlapped the two strips, to see how “off” the pattern match will be. I am preparing to splice these two strips together, and will use some tricks to make that pattern mis-match less noticeable.

Next, I padded the wall with some scrap paper. This means that I placed a width of scrap paper behind these two pieces that will be spliced together. This is to protect the wall from being scored when I make my splice. You don’t want to cut into the wall when doing a splice, because, when the wallpaper dries and pulls tight, it can put tension on the wall, sufficient to cause the layers to delaminate and pull apart, creating a “popped” seam.

Next, I took a sharp, new razor blade and cut through both layers of wallpaper, using the swerving lines in the damask design as a guild – a swerving cut will be less noticeable than a straight like that cuts abruptly through the pattern.

This is tricky, because you want to cut through two layers of wallpaper, but not into or through the third layer that is being used to pad and protect the wall.

Second photo – I screwed up! For some reason, I had trouble cutting through the two layers of wallpaper. I tried twice, but each time I only cut through one layer. So I attempted it one last time, making sure to push really hard on the razor blade.

Well, now the razor blade was ready to do its job … But it was too zealous … This third attempt, the blade cut neatly through both layers of wallpaper, which is good. But it also cut through the third layer of wallpaper I had put behind everything, to protect the wall. And into the wall underneath. In the photo, you can see how the drywall was scored. This is bad.

To prevent the drying / shrinking wallpaper from tugging on those cut edges of drywall, I grabbed some special paper tape I keep in the van, and placed strips over the curved cuts in the drywall. These are very difficult to see, but the paper strips are there, in the third photo.

Then I fit the two strips of wallpaper back together, smoothing them into place over the paper tape. Then I made sure to wipe off any paste residue that was left on the surface.

Now, if those two spliced strips of wallpaper should shrink as they dry and put tension on the wall, the tension will not be on the cuts in the wall, but rather on the strips of paper. The strip of paper tape will disperse the tension over it’s 1″ width, and keep it away from the weakened areas of the cut drywall. This should prevent any delaminating of the drywall, and prevent any popped seams.

In the last photo, we are back to hiding that last seam, the “kill point.” From down below, your eye will never pick out any pattern mis-match. Mission Accomplished!
