Good Catch After a Mistake

November 19, 2019

Whoops! Somebody (me 😦 ) cut a wallpaper strip to 6’24” instead of 6’34”.

This William Morris wallpaper is expensive, and I didn’t want to just throw away the too-short piece. So I figured a way to use scraps to save it.

At the bottom of the too-short strip, I trimmed horizontally along an element of the design. From the scrap pile, I found a piece with a corresponding pattern, made sure it was the right length to reach the baseboard, and then trimmed the top horizontally to match up with the design on the piece already on the wall.

The reason I trimmed along the swoopy line of the design is that I wanted to eliminate a straight horizontal ridge showing under the two strips once they were overlapped on the wall. The eye might notice a wide, non-conforming, horizontal ridge, but it won’t notice a narrow overlap that follows the contours of the pattern.

I put the short strip in place, and the pattern matched perfectly.

But there was a slight sheen from above, glinting off of the cut edge of the wallpaper in just a few spots. You can just barely see this in the second-to-last photo.

So I pulled the two strips of wallpaper apart and put them back together, but reversed the sequence, overlapping the top strip onto the lower strip. Now there was no cut edge for light to catch or bounce off of, and now the overlap / ridge is completely invisible.

Note that the surface of this wallpaper was a vinyl (plastic) material. Wallpaper paste won’t stick to plastic very well (it’s too slick). There is a special adhesive called VOV – for Vinyl Over Vinyl – formulated to make this bond. But I don’t always trust it.

So I often use clear caulk, which I call Super Glue for Wallpaper. Under the right conditions, it’s a wonderful solution.

Note: There is a technique called a double-cut, which is a method of splicing two strips of wallpaper together. A double-cut eliminates the possibly-visible ridge that you get when you overlap strips of wallpaper. For various reasons too complicated to get into here, in this case, and especially down low and behind the toilet, I preferred to use the overlap-and-super-glue technique.

One More Reason to NOT Let Your Handyman (or Contractor) Prep the Walls

Can you see the vertical line dead-center in this photo? That is the ridge in a swipe of wall-smoothing compound that is showing under the wallpaper.

For various reasons, the homeowners elected to have their contractor’s guys smooth the textured walls of this powder room. They didn’t do a bad job. But, well, I would have done better.

The crew did a good enough job smoothing the center areas of the walls. But when it came to corners and edges, and especially around the ceiling light fixture, they left a lot of rough areas. Rough areas mean that the wallpaper won’t have a sound, solid surface to adhere to. And they mean that these rough, irregular spots will show under the wallpaper.

In the case of what you see in the photo above, they must have forgotten to sand the smoothing compound, because the ridge between swipes of their trowel is still there. Depending on how the light hits it, it is not – or is – visible.
