Minor Bubbles, Waffling, Quilting on Wallpaper

A lot of high-end wallpaper manufacturers use heavy inks (a.k.a. stinky ink). When wet paste is rolled on to the back of the wallpaper, these inks commonly compete with the substrate for moisture. The substrate absorbs more moisture and more quickly than the inked areas.

The result is wrinkles, blisters, bubbles, warps, quilting, waffling – whatever you want to name it, you’ve got a bumpy surface that doesn’t want to lie flat on the wall.

One way to tame this beast is to LIGHTLY sponge water onto the surface of the paper, before pasting. This allows the front to absorb moisture at the same time that the backing is soaking up moisture from the paste. The result is a more even “quilting” of the material.

Another thing to keep in mind is that small blisters like seen in the photo will usually flatten out and disappear as the wallpaper paste dries. A good wallpaper-specific primer underneath is a big help.

Also, a liner paper is often a good choice. The liner is a special, unprinted paper that goes under the decorative wallpaper. The liner absorbs moisture quickly and helps “lock down” bubbles and seams.

A liner also ups the installation price. Because you have to add the cost of the material, plus the labor of at least an additional day to hang the liner, and then let it dry at overnight or longer.
