01 / 02
Foam & board
Hold the can off the surface and spray an even coat over both faces of the foam, board or foil. Let it tack off, then bring the parts together and press across the whole sheet for an even, flat bond.
02 / 02
Panel & case lining
Spray an even coat onto the panel or case, then lay the foam or fabric lining on and smooth it from the centre. The film grips without soaking through or bleeding, so the face of the lining stays clean.

Frequently asked questions
Taftspray 78 is a multipurpose sprayable synthetic elastomer adhesive for permanently bonding lightweight materials, including paper, cardboard, felt, cork, foils, carpeting, lightweight foams, cloth, wood, hardboards, and painted or unpainted metals. At 25% solid content by weight, it suits artwork mounting, signage, foam upholstery, and general woodworking where a high-tack, high-coverage bond is needed.
The technical data sheet lists lightweight foams among its bonding substrates, which makes Taftspray 78 a practical choice for polyurethane foam upholstery and lightweight craft materials. Ask MightyLoc before spraying it onto expanded polystyrene.
Taftspray 78 has a bonding range of 10 seconds to 15 minutes for a single sprayed surface, and 10 seconds to 30 minutes when both surfaces are sprayed. For extra-strong bonds, spray both surfaces and allow a minimum of 30 seconds drying time before joining. Make the bond while the adhesive is still aggressively tacky.
Taftspray 78 is translucent both wet and dry, so it dries to a near-clear film. Its low soak-in gives a better appearance, higher adhesive coverage, and soft, non-dimpling glue lines. This keeps the finish clean on artwork mounting, photo mounting, and signage, where a visible adhesive line would be unacceptable.
Hold the Taftspray 78 can 15 to 20 cm from the surface during spraying. Shake the can well first, then turn the spray tip so the arrow points to the dot on the rim, and spray evenly. This distance, combined with the low-mist, fine-particle spray pattern, gives controlled coverage with reduced overspray and misting.
MightyLoc does not publish a coverage figure that can be relied on, so ask MightyLoc for your job. The can holds approximately 450 grams net weight; actual coverage varies with spray technique, substrate porosity and whether one or both surfaces are coated.
Taftspray 78 has a maximum shelf life of 24 months from the date of manufacturing. Store the can at 16 C to 28 C for maximum storage life, away from direct sunlight and direct flame. High temperatures can reduce storage life, while low temperatures may temporarily increase the spray viscosity.
Taftspray 78 has a flash point of -40 C, so it should be used in a well-ventilated area away from sparks, open flame, and direct heat. Its volatile organic content is 52%, and the technical data sheet lists no hazardous air pollutants. Refer to the Safety Data Sheet for health and safety information before handling this product.
Taftspray 78 can be applied to one or both surfaces depending on the bond needed. Single-side spraying gives a 10 second to 15 minute bonding range, while spraying both surfaces gives a 10 second to 30 minute range. For an extra-strong bond, spray both surfaces and allow a minimum of 30 seconds drying time before pressing the parts together.
For best results with Taftspray 78, the adhesive and the surfaces being bonded should be at least 18 C. Surfaces must also be clean, dry, and free from dirt, dust, oil, loose paint, wax, and grease before spraying. Colder substrates can slow tack development and may temporarily increase the adhesive's spray viscosity.
