Puckered Seam Due to Material Expanding

This is a popular wallpaper pattern, and the previous times I’ve hung it it was called “Wood” by Cole & Son. It has a matt finish and has always gone up beautifully.

But today I hung the same pattern, this time curiously with a label from “Blooming Wall.” The material had shiny surface. Both brands are a non-woven substrate and a paste-the-wall product. Because the material is dimensionally stable, it will not expand when it gets wet with paste like regular wallpapers will. So you can put paste on the wall instead on the back of the paper, and hang your strips immediately, with no booking / soaking or waiting. The Cole & Son performs as it’s supposed to.

But this Blooming Wall product did soak up moisture from the paste, and shortly after I put it into the paste on the wall, it expanded just a little, causing puckers at the seams. It also warped and twisted a little, and created bubbles that had to be worked out or cut open.

Once I figured out what was going on, my solution was to lightly dampen the back of each strip with water, to allow the material time to absorb moisture and expand before it got to the wall. This did help eliminate the seam puckers and the warping.
