Wallpaper Seams Split – White Showing At Seams

March 31, 2020


I hung this Bradbury & Bradbury digitally-printed wallpaper from their new ’20’s Vintage collection yesterday. When I left, the seams were perfect, and the job looked super.

Yet overnight, the paper dried and shrank, and that left some gaps at the seams. In the top photo, you can see the white primer peeking out from underneath. (Note: I have not had any opened seams when I hung their more traditionally-printed papers, including a dark brown paper in my own master bathroom.)

If the paper is allowing of it, it is possible to use craft paint or chalk pastels to color in the open space between the edges of the two strips of paper.

You have to test before moving forward, because some papers have a porous surface that might absorb the colorant and leave a mar or smudge on the surface. Usually, chalk is the safest way to go.

Easy Peasy Wallpaper Removal

This wallpaper is dry-strippable, which means that it is coming away from the wall with just a gentle tug, rather than needing water or a lot of time and various steps to remove it.

This is partly because of the type of paper and the paste used by the previous installer.  But it has more to do with the fact that he hung the paper on the  porous surface of a newly-floated (smoothed) wall, and didn’t bother to prime / seal the walls first.

In fact, the wallpaper was failing and coming away from the wall on its own, long before I arrived to replace it.

A simple primer, a few dollars, and about an hour’s time would have prevented this.

Sometimes You Want a Pigmented Primer

Rolling on a primer is an essential step before hanging wallpaper. I have a white wallpaper primer that works well much of the time. But for porous surfaces, I use another primer, called Gardz, which soaks in and seals the surface nicely. This product is clear.

But sometimes I want a white base under the wallpaper. So, if need be, I can add a little bit of another primer made by the same manufacturer (Zinsser), called Bin 123. It adds a little bit of color, but still remains thin enough to allow the Gardz to soak into the surface. The 123 also gives a little more bite, enabling the Gardz to stick to a semi-gloss surface (which it normally only sticks to porous surfaces).

Here is a picture of how it looks going over a dark olive painted wall. I was pleased with how this worked, and will be using it again.
