Re: Photomount spray for works on paper? Good idea or disaster? X
My luck with spray mounting has not been good. The corners tend to lift up over time. Permanent mounting spray holds better than the removable type. The problem with the permanent ones is if something goes wrong, you cannot undo it.
I would recommend Beva 371 liquid or something similar. If you have access to a heat mounting press, then any of the archival, removable mounting tissues will do the job but the press can have problems if your painting has thick passages.
