the upper plastic sheet is bendable and the lower sheet is rigid. I need some type of glue that I could brush on easily to stick them together.. Since I may need alot of that glue, are there cheaper options for me?
Not knowing what type of plastic it is, the only two glues that may work are; Superglue; if it doesn't work, then try; PVC plumbers glue. Both can be purchased at a Big Box home Improvement Store for cheapest prices, or your local hardware store. Vapors from the PVC glue are flammable and toxic, so use in a well ventilated area only. Work safe, be safe. Good Luck with the project.
A spray adhesive will be your best bet. It will be the fastest and easiest and most cost effective considering the large quantity of items that you will be gluing. You will need an empty box to be your spray box so that you have a space to confine the over spray, and news papers to place in the bottom, enough to have on hand to put down on top of each other as a new clean surface after doing a few. I can suggest a brand called Super 77 Spray Adhesive or Elmer's Spray Adhesive. ***The Elmer's costs way less than the Super 77 (the Supper 77 is industrial strength stuff) Spray adhesives can be purchased at any home improvement stores, hardware stores, craft hobby stores as well as Walmart. I use spray adhesive all the time on a multitude of home crafting projects and it works on just about all surfaces. The only thing that it will do harm to is certain kinds of styrofoam, it will sometimes chemically melt that. But plastic surfaces will be just fine. I hope this helps you with your project! Good Luck!
