Bond Styrofoam with Great Stuff foam sealant

We often make interior signs, displays and props from extruded polystyrene foam, often called Styrofoam. We laminate it to the thickness we need and join panels together, then rout and shape it. This display for a vacation bible school program is a good example.

Recently we learned that you can use the expanding foam insulation that comes in a spray can, such as Great Stuff foam sealant, to bond this foam material together. It works great. We spray the foam on one surface, squeeze the panels together, then put a weight on them until the Great Stuff dries.
