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!
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.
Step 2: Something Smells Funny...
Another thing you can do is to spray outdoors. If the weather is nice, this can be a viable option. In the photo of the outside scene, I have demonstrated what you want to avoid with accumulating too much spray on your material.
As a note, it is always good to use protection! However, some of us like to live on the wild side, and if it is a quick job, you should be fine. Of course, what I am referring to are gloves and a respirator. In terms of gloves, iif the spray gets on you, it wont kill you with, but getting adhesive on your hands can be a pain. My own general rule is that if i am spraying for more than 2 minutes, i put on gloves because it i will make cleanup (of my own hands) easier. Now, to address respiration. When i have one or two quick sprays to do, I normally just hold my breath when I am spraying. However, whenever i am doing multiple sprays for an extended period of time, I use a respirator. A simple dust filter should suffice.
*As a note, some people can be allergic to the chemicals in Super 77. It is always best to use this, and really any other chemical heavy product in an area where human exposure is minimal
Step 3: Some People Like It Tacky!
That is it! Now you just stick your pieces together, and let them adhere. It is advisable to put some weight on things, but you don't have to clamp it together. It a few minutes, the piece will be moveable.
