How long does Gorilla Glue Original Polyurethane Adhesive take to cure on Foam Insulation (EPS / XPS)?

Gorilla Glue Original Polyurethane Adhesive takes 24 hours to fully cure on Foam Insulation (EPS / XPS) at 70°F and 50% RH. Temperature and humidity significantly affect this — use the calculator on this page for an adjusted estimate at your actual conditions.

How do I prepare Foam Insulation (EPS / XPS) before applying Gorilla Glue Original Polyurethane Adhesive?

CRITICAL: Never use solvent-based adhesives on EPS or XPS — they will dissolve the foam instantly. Use only water-based or foam-safe adhesives. Check the label specifically for EPS/XPS compatibility.
