How To Use DAP Contact Cement
You might think DAP Contact Cement is glue, like Elmer's or super glue. That's not quite the case, however. When you used Elmer's glue in elementary school, you put it onto one of the things you're gluing, stuck that to the other thing, and waited until it dried. DAP works differently.
DAP is a contact cement. What that means is that, when two surfaces spread with DAP come in contact with each other, they cement together and are very difficult to pull apart.
But DAP isn't just a cement; it's a cement in a liquid medium. That liquid medium is what keeps DAP from just being a block of hardened cement in the can. It's also what lets you spread it on your surface.
Once DAP has been spread on a surface, the liquid starts evaporating, allowing the cement to start bonding to itself and the surface it's on. The more that liquid evaporates, the better it's able to make its bonds. Once it's dry, there's nothing left keeping it from bonding to itself. That's when you bring the second surface, also treated with a dry application of DAP, in contact with the first. It'll bond with the cement on the other surface instantly. Fast like you better have your aim right on the first shot; you may not have time to correct it before it's stuck. You know it's dry enough to stick to itself when, if you touch the surfaces, it doesn't feel sticky or wet or tacky to you (unless there's DAP on your skin... then it'll stick to that!).
I've found that it takes the liquid about 20-30 minutes to evaporate, depending on weather and ambient temperature. I've gotten lucky with 15 minutes on a hot, sunny, dry day.
So, that said, how do you use DAP?
And voila! You now know how to use DAP Contact Cement. Now, go build your sword!
