The best glues to use on Styrofoam are the actual Styrofoam glues such as UHU Styrofoam glue, Weldbond and 3M 77. Styrofoam glue comes in both tubes and spray. The adhesive spray, like 3M 77, makes creating projects easier and without the mess. With 3M 77, the glue dries fast and provides permanent bonding.
