Commonly used to bond light- to medium-weight materials together such as paper, foam and fabric or to bond those to weightier items like wood, metal and certain plastics, spray adhesive comes in many different varieties. Produced by brands like 3M, Elmer's, Krylon and Misty, spray adhesives have the advantage of being quickly applied, fast tacking and fast drying. With little mess to clean up, spray adhesives typically have a low soak-in rate, meaning that most of the adhesive stays on the surface of even highly-porous materials. This leads to stronger, more secure bond.
Multipurpose Spray Adhesive
Available from brands such as Elmer's, 3M and Krylon, multipurpose spray adhesive is useful for a wide assortment of tasks. Spray adhesive is applied through an aerosol can. 3M, for instance, offers variable nozzles from 1 to 3 inches so you can adjust the width of the plume. Spray adhesives are largely water resistant, they dry clearly, and they will not stain materials, whether it's fabric or photographs.
Spray adhesives form an aggressive tack that is fast drying. Some types, however, slow down the set time of the adhesive, giving you a chance to reposition the material being bonded. The aerosol cans give you precise control of the adhesive as it's applied. Spray adhesives are typically made from synthetic elastic polymers mixed with a variety of solvents to prevent it from hardening.
The uses for spray adhesives are many. From general craft-making, art and school projects, model building, and holiday designs to the repair of fiberglass insulation and other home improvement tasks, spray adhesives come in several strengths. Heavy-duty spray adhesives are designed to withstand higher heat exposure while maintaining an extra-strong bond. Multipurpose spray adhesives can be strengthened by applying the adhesive in double, crisscrossed layers. Cleanup of spray adhesives is minimal, but the nozzle tips may be wiped with turpentine or specially-designed adhesive remover to keep them from getting clogged.
