I'm starting a series of collages where I'm attaching bits of photos to other photos, and I'm curious about the best adhesives and sealants for archival purposes.
The photos in question are C-prints, not inkjets. Some will be digital C-prints from a lab, and some might be from a darkroom -- but they'll all be on Fuji Crystal Archive paper.
My goal is to have the adhesive be as permanent as possible and for the sealant to dry clear and stay clear over the years (and not alter the colors of the photos).
I'm new to collage, so I'm learning as I go along. I've done some Googling and looked at various web forums (like this
), but none seem to deal specifically with photos on photos. I guess I've got it easier than some collagists (sp?), as I'm dealing with relatively thick photos and not thin old newsprint, but of course photos have issues of their own.
I've done a few test runs with Crafter's Pick brand "Decoupage and Collage Gel," which says it's archival; it dries clear and seems fine. But I know there's a ton of stuff out there.
Bonus: If I mount these collages on wood or aluminum or cintra, what's the best permanent adhesive for that? I've previously had some C-prints professionally mounted on cintra, and a few are beginning to unstick at the corners after only a few years. Though maybe it was just a bad mounting job. I'm not sure what adhesive they used.
thanks for any help!
