Craft Spray Adhesives

Tack grade is the decision and it is irreversible if you get it wrong. Repositionable formulas let a mounted print be peeled and realigned for a while before they set; permanent grades bond on contact and tear the paper if you try. Either way this needs open air or an extraction booth rather than a classroom, and masking around the work saves the table. See craft adhesives, glues and mounting strips.
