How to Glue Styrofoam Foam
Use a glue for non-porous materials, such as styrofoam. (styrofoam business image by robert mobley from

Styrofoam, manufactured by the Dow Chemical Corporation, is a brand name of a lightweight plastic foam product made from extruded polystyrene. Many people use the word 'styrofoam' to refer to plastic foam products made by other companies. Therefore, there are a large number of formulas used to produce this type of foam. Because of this, some types of glue may not be suitable for all of them. The foam is used in crafts, insulation, packaging and many other applications.

Things you need

  • White craft glue or other glue for non-porous material

  1. 1

    Use white craft glue. This is the glue that will work on most foam brands. Any glue you use should be for a non-porous material. Avoid any glue that contains a solvent because it will melt the foam and may release toxic fumes.

  2. 2

    Insert toothpicks or wooden or bamboo skewers into the separate pieces of styrofoam you are gluing to hold it together until the glue dries. Allow the glue to dry completely before carving or painting the styrofoam.

  3. 3

    Hot glue other materials to styrofoam by applying the hot glue to the other item first and allowing it to cool slightly before placing it on the styrofoam. Do not put the hot glue directly on the foam.

Tips and warnings

  • Buy a glue that is made specifically for styrofoam. You can find these types of glues at a craft supply store or at an online craft retailer.
  • Stay away from using high-temperature hot glue guns because the glue can melt the styrofoam, forming a small depression. Some foams may release toxic fumes if they are melted. However, low-temperatures glue guns are acceptable.
  • If you are gluing two pieces of foam, rub them together before you apply the glue.
