Was wondering if anyone has had success using spray adhesive to bond leather to proofgrade plywood? I have done a few test runs with limited success.
I have been making small cribbage boards out of PG plywood that are attached to a piece of leather and able to fold closed, but the glue up process with traditional materials is laborious.
Proofgrade has a sealed finish on it, did you try scuffing the surface with rough sandpaper first?
Similarly, adhesives only work well on the rough side of leather and not the smooth/skin side.
Not all spray adhesives are equal. The best leather to leather or something else adhesion is with a contact cement like Barge or Weldwood (apply to both pieces, allow to dry separately until tacky and then press together with lots firm pressure). They’re usually sold as a canned liquid but there are some contact cements that come in spray form.
This - if I’m cutting a design into PG that will need to be glued I add a bunch of score lines across the to-be-glued area so the glue can get beyond the shiny top coat.
