Blue Birds Brighten a Bathroom – But Not A Good Quality Paper

June 27, 2018


The original wallpaper had fallen victim to curled seams. This happens most often with lower-end pre-pasted, paper-backed, solid vinyl wallcoverings, particularly in humid rooms, like this bathroom. Adding to the list of no-no’s were an improperly smoothed wall and the lack of a primer.

The seams on these papers are never great to begin with. When there is humidity, it will find its way into the seams and onto the paper backing of the wallpaper. When this backing gets wet by humidity, it expands. When it expands, it has nowhere to go but out – pushing away from the wall. This results in a curled seam. This is not “loose” wallpaper, and the seams cannot be glued back down. In many cases, the paper backing layer of the wallpaper actually delaminates (separates from) the top vinyl layer.

The homeowner loved the pattern, particularly the blue birds, and bought the same exact paper to replace the other. I stripped off the old paper, took various steps to stabilize the unsound wall surface, then skim-coated the wall to smooth it, primed, and hung the new paper.

The look is cheery and bright, and looks fabulous with the pale yellow bead-board wainscoting. The seams looked good when I left, and will pull down tighter as the paper dries.

Still, these economical pre-pasted, paper-backed, solid vinyl wallpapers are not my choice for use in any room. And this particular brand (Norwall) just about tops my list for brands to NOT purchase.

Stay Away from Low-End, Pre-Pasted, Paper-Backed, Solid Vinyl Wallpaper

June 6, 2018

For now, I’ll just say that I really dislike these papers, because the seams are always visible, and usually the paper is curled back a little at the seams.

The reason is because the gritty manila-type paper backing will absorb moisture from a humid room (think steamy showers), or will soak up water if they are splashed on (think bathtubs and kitchen sinks).

When the paper backing swells with moisture, it grows, and it can only go in one direction, which is to push away from the wall. That means that the printed / vinyl surface will bend backwards along with it. So now you have a curled seam.

Sometimes this goes a step further, with the bottom paper layer actually delaminating (separating from) the top vinyl layer, also resulting in a curled seam.

These are not “loose” seams. They cannot be simply glued back down. The curling and the delaminating are characteristic of a lower-end product made with paper on one side and vinyl on the other, reacting to humidity in the room.

It doesn’t have to be a humid room, either. Usually these seams never look good and flat, even when the paper has just been installed. See third photo.

Bottom line: Steer away from these products. Rather, choose a paper wallpaper, or a non-woven material, or other instead. Ask me to check your selection, before you make the purchase.
