How to Glue Styrofoam to Wood

Glue styrofoam to wood and clamp it while the glue bonds.

Styrofoam is also a nonporous material, which means that it will not absorb adhesive. Select a strong adhesive and give it ample time to set before you test the bond.

1. Apply a thin layer of glue to the wood where you wish to attach the Styrofoam. Spread the glue out into a thin coat with a paintbrush, if necessary.

2. Affix the Styrofoam piece onto the wood over the glue. Adjust the Styrofoam on the wood until you have it in the position you desire.

3. Attach the c-clamp over the Styrofoam and wood to hold the two items together securely. Use more than one c-clamp if the pieces are large. Space the clamps six to eight inches apart and tighten them enough to hold the Styrofoam in place without marring the surfaces of the Styrofoam or the wood.

4. Leave the c-clamps in place while the glue sets--at least two hours for best results. Remove the c-clamps after the glue dries completely.

5. Tug gently on the Styrofoam to ensure that the bond is secure.

Tip

Duct tape makes an effective clamp for holding Styrofoam and wood together during the bonding period if you do not have c-clamps. Wrap the duct tape tightly around the glued pieces and leave it in place for two hours. Alternatively, hot glue is also effective for gluing Styrofoam to wood. Apply the hot glue to the wood surface and allow it to cool for two to three seconds before pressing the Styrofoam into place on the wood.
