Tips and Techniques
Use at room temperature.
3M™ Super 77™ Multipurpose Adhesive works best at room temperature (60°-80°).
Keep it steady.
A light but thorough coating works best, and two coats are much better than one heavy coat.
Keep your distance.
Hold the can upright about 6" to 8" from the surface to spray. Spraying too closely can wet the surface and cause puddling, which can extend drying times, weaken the bond, and affect the look of the finished project.
Right is right.
Try to hold the can as upright (vertical) as possible. This will ensure that the adhesive sprays evenly on the surface. Holding the can horizontally, particularly when the can is nearing empty, may cause uneven coverage.
Protect from overspray.
Remember to protect surfaces from overspray. Just use an empty cardboard box, mask off surfaces with tape or paper, or cover the work surface with newspaper or other disposable material.
Start off. Finish off.
For the most uniform coverage, always start spraying from 2" to 3" off of the project's surface on one side and finish spraying 2" to 3" off of the project's surface on the other side. Be sure to protect surfaces from overspr
Wait 30 seconds.
Wait approximately 30 seconds after spraying before attaching the surfaces together. This allows the solvents to evaporate and improves the bond strength.
Save the nozzles.
Nozzles can get clogged. To combat this, try soaking clogged nozzles in turpentine or mineral spirits to loosen the adhesive. Also, save good nozzles from empty cans to use as replacements.
Avoid bubbles.
A good way to help eliminate trapped bubbles when gluing surfaces is to apply pressure starting from the center of the material and then carefully working outward.
Purge the can.
To extend the life of the can of 3M™ Super 77™ Multipurpose Adhesive, turn it upside down when the project is complete. Spray into a safe location (like an empty box) until the glue
Removing overspray.
Adhesive overspray is always better prevented than removed. But several common solvents can help clean it off, including mineral spirits, turpentine, citrus-based cleaners or 3M™ Adhesive Remover. Be sure to follow proper precautionary measures when using solvents!
On hands, apply baby oil, cooking or vegetable oil, followed by soap and water.
On furniture, use a furniture polish.
On fabrics and carpet, first remove as much glue as possible with masking tape. Then dab the surface with a cloth dampened with one of the solvents listed above.
Or spraythe surface directly with 3M™ Adhesive Remover or a citrus-based cleaner.
Always test solvents and cleaners on inconspicuous areas of fabric or carpet first.
When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer's precautions and directions for use.
