Special Paste for Special Paper

July 22, 2020


Most wallpapers can be hung with standard wallpaper pastes. But some papers are more delicate or have special characteristics (silk, vintage, non-woven, prone to curling seams,) and thus call for special pastes.

When certain pastes are used, non-woven wallpapers like this one can display “blushing” or “staining,” which look like wet spots that never dry.

This manufacturer, Rebel Walls, has included a box of paste that is specially formulated to work with non-woven material. It is a powdered potato starch-based paste that is mixed with water on-site, allowed to set up, then mixed again, and then it’s ready to use.

To be honest, I probably wouldn’t use this paste. With the propensity of non-wovens to blush and stain, the less moisture you introduce, the better. So I would opt for a pre-mixed clear paste, such as Roman’s 838 or SureStik 780. But beware – some other types of clear pre-mixed pastes will stain (880, 234) and probably clay pastes will, too.

This very popular wallpaper pattern is by Cole & Son, and is called “Woods.” I have hung it in the black-on-white many times (do a Search here – upper right), but this is the first time to do it in this softer colorway. The d├ęcor in this home is all soft and muted greys and taupes, with a lot of natural materials (wood, stone) tossed in, so this pattern and color are a perfect compliment.

The wallpaper material is called non-woven, which has a high fiberglass content. This means it doesn’t expand when wet with paste, so there is no booking time – meaning you can hang each strip as soon as it is pasted. In fact, you can paste the wall and dry-hang the strips, if you choose. Another advantage of non-wovens is that they are dimensionally-stable, and do not expand when wet with paste, like paper wallpapers do. Very handy when measuring and laying out the room.

A disadvantage of non-wovens is that they are prone to staining and blushing. This is where the paper looks like it is wet, but it never dries and disappears. Certain pastes (880, 234) are known to cause staining on these materials, as well as too much pressure while installing, or wetting the paper with water.

This laundry room is in a newish home in Pearland, a suburb in south Houston.
