This spray adhesive is suggested for use with open-cell foams and closed-cell foams. 3M Super 77 is commonly used for custom packaging, arts and crafts, cushions, and mounting acoustic foam.
Do not use 3M Super 77 when gluing Polystyrene materials. The chemical structure of this adhesive melts the foam. As an alternative, Camie 373 can be used.
IMPORTANT: Concrete/Cinderblock Surfaces
Spray adhesive is ineffective at bonding foam to painted or bare concrete or cinderblock walls. For permanently adhering foam directly to these surfaces, heavy-duty construction adhesive is suggested. Note that this will damage the foam and leave residue on the wall if removed. For non-permanent installation, we suggest mounting the foam to a substrate, such as plywood or sturdy cardboard, and hanging the mounted tile(s). Our spray adhesives may be used to form the foam-to-substrate bond.
