Anyone have experience with spray adhesives like Spray Mount or Elmer’s Craft Bond? How permanent is the adhesion? After a period of time, does the material start to separate? And what about discoloration? I am working on a project that includes affixing Japanese rice paper (like tissue paper) to a surface that has been painted with acrylic paint, and I need to know how long it will last.
I’ve used spray adhesives when I work as a custom framer, but only on heavier stock (photographs, posters). It was pretty permanent, so we never used it on anything that was meant to be archival.
Rice paper is pretty thin; the adhesive may soak in and discolor it.
I’d try testing a small piece of the paper on a small piece of the backing first.
Of course . . . except that I need to know whether it will separate or yellow, years or decades from now.
There are several formulations. Spray Mount is meant to be repositionable, and can’t really be relied on for a long-term high-strength bond, especially after it was reformulated in the early 90s. Photo Mount and 77 are meant to be much more permanent. I’ve used the stuff for several decades and never noticed any particular yellowing. I have in hand some tissue comps and also a Rubylith mask that I sprayed in 1979 and put in a notebook. The parchment tissue has some yellowing, but nothing I can attribute to the Spray Mount. The Rubylith base is still clear.
