White glue is a safe option for styrofoam.
Trailers and RVs sometimes have a layer of Styrofoam between the aluminum roof and ceiling fabric. In the event of damage, you may opt to replace the ceiling yourself by gluing a new layer of foam to the ceiling. Avoid using glues that contain any type of solvent as this dissolves the Styrofoam. Dow Chemical, the company that makes Styrofoam, recommends using white glue or a low-temperature glue gun.
Instructions
Cold Glue
1. Squeeze the glue onto the side of the Styrofoam that will attach to the ceiling.
2. Spread out the glue over the entire surface with a glue roller to ensure even coverage.
3. Press the Styrofoam to the aluminum ceiling and hold it in place until it sticks.
4. Smooth your hand gently across the surface of the Styrofoam to ensure the entire surface is in contact with the ceiling.
Hot Glue
5. Apply the hot glue directly to the metal and spread around with a glue roller. Hot glue can melt Styrofoam if applied directly to it.
6. Line up the Styrofoam piece with the glue on the ceiling.
7. Press the Styrofoam onto the ceiling and smooth over the surface lightly with your hand.
8. Hold the Styrofoam in place until it sticks without falling.
