Another Installer’s Problems With British Pulp Paper

Scroll down a few posts to see where I hung this exact same pattern, and coincidentally just a few blocks away. I had absolutely no problems. Yet this poor installer struggled and ended up with many dissatisfactory issues.
In this photo, you see where the wallpaper has shrunk at the seams and left a gap, some tears, and a patch to cover a mishap.
More tears and gaps.
Paper coming lose from the wall. Not taking primer or paint with it. But you can see the adhesive clinging to the back of the paper. I’m suspecting this is clay adhesive. Nothing wrong with clay, but I prefer one of the vinyl-based adhesives.
Not sure what the guy used as a primer (if any).

This is the popular Strawberry Thief by William Morris , usually sold by Morris & Co. I’m believing the problem here is the material on which this pattern was printed.

The site from which this was purchased called it a ” heritage ” paper. It is, indeed, made of what we call a British pulp material. Old-fashioned, it is. These days, most wallpaper coming from the U.K. is printed on non-woven stock. The paper I hung a few days ago was non-woven.

Pulp wallpapers have a nice look. But they have no protective coating, so become soiled easily. They soften when wet with paste and tear easily, and can also shred under the razor blade while trimming. They expand when wet with paste, and then shrink as they dry, which often results in gaps at the seams.

Even skilled installers can have difficulties when working with this stuff. In fact, on the private Facebook page of the Wallcovering Installers Association ( WIA ), we have just been discussing this very same topic.

I believe this previous installer had a few shortcomings, such as lack of skill and maybe used the wrong or no wallpaper primer. But I think the real and unsurmountable culprit was the substrate.

Moral: If given the option, choose a non-woven material. They are made with minimum 20% polyester content, and thus are resistant to shrinking, tearing, and tension at the seams. Many other advantages, too. Non-wovens are also referred to as paste the wall .
