Sticking things together can be a pain sometimes, especially if you are using inferior adhesives. If your goal is to do precision gluing, than this product may not be for you (You should be looking at high end super glues, or some brush on adhesives). However, if you want to cover large areas with a product that does not fail you, and can be used on a number of materials, than Super 77 is the answer!

The beautiful thing about Super 77 is that it is relatively cheap ($5-$10 depending on your area) and can be found almost anywhere. It can adhere most products, such as paper, fabric, films, plastics, wood and foam.

This multipurpose spray adhesive is a great, fix all product, that generally is cheaper and better that many specialty adhesives for things like photo mounting! When properly used Super 77 normally does not distort or bleed into your material, which is one of the main reasons I choose this product over other adhesives. That being said, always test the product on a scrap piece to make sure it will work for you!

Step 1: DISTANCE DISTANCE DISTANCE!

Picture of DISTANCE DISTANCE DISTANCE!
One of the key things to using Super 77 spray adhesive is distance. This distance i am referring to is the distance from the spray cap of the can to you material. 3M advises that this distance should be between 6-8 inches. An obvious happy medium is 7 inches. This is really more of a guideline than anything however. You don't ever want to get closer than 6 inches, because it will accumulate too much adhesive on your project, which will ruin it, but you can spray from a farther away distance. There are times that I spray from a 10 to even 15 inch distance. This help spray out a very light adhesive layer that can result in a much cleaner (and slightly less strong) adhesion.

Another good point to make is to not build up the adhesive layer on your material. Spray adhesive works very similarly to spray paint. If you spray to much, it will not dry properly, and it will do weird things. One light pass over you material should do it, if you need, another pass will be OK! The goal is for the sprayed area to have an even, light spray layer, and to not have any sort of buildup or irregular texture.

I have a small 4 oz. can of Elmers Craft Bond Spray Adhesive. It says " for Permanent Bonds, join surfaces within 15 seconds while adhesive is still tacky, Allow to set at east one hour " I am guessing this is similar stuff! I am doing a test to see if I can glue some camo material to a wood sheath. Gurkha knife makeover. Thanks.

Very interesting, and very cool.

I genuinely want to know how that works out for you. I am always on the lookout for other useful product. I assume this object may get some wear and tear, lets see how it holds up!
The smaller cans of 77 are not commonly seen and have a similar appearance to silly string. Do NOT make this mistake. It is not stringy and rarely silly.

Yes, one of the most important things to remember is to let the adhesive get tacky. It is basically spray-on Contact Cement.

For super strong bonds, you can spray both components, and allow them to get tacky, then stick the both together.... BAM!
