Rebel Walls Gives You Paste

I carry 5-gallon buckets of wallpaper paste in my van. But to make it easy for DIY’ers, rebelwalls.com includes a box of paste with every order. This is powdered paste that needs to be mixed with water. This may be lightweight and easy to ship, but I don’t like to use it when hanging a non-woven material like theirs.
Non-wovens are prone to staining and blushing (look like they’re wet but never dry out) . Most often this is caused by the paste – usually a paste that is too “wet” or, in other words, has a high moisture content. Roman 880 is notorious for this, as is Dynomite (now Roman) 234.
But a paste that you make by mixing powder into water seems even more risky for having a high water content, and causing staining. And so is the practice of dampening the back of the paper with a damp sponge, or a spritz of water from a squirt bottle. In my mind, too much water / moisture = risk of staining or blushing.
I say, skip the anxiety and use a low-moisture pre-mixed vinyl adhesive such as Roman 838 or Dynomite 780 (also now made by Roman). Clay pastes are also known for low water content – but I definitely do not recommend on a non-woven material, as I’ve seen the red clay bleed through far too many wallpaper surfaces.

Special Paste for Special Paper

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.
