BOSS 333 is a ready-to-use, multi-purpose polyurethane foam that expands to three times its original volume on contact with air. The expanding action fills holes, cracks and gaps more completely than standard caulks. BOSS 333 has excellent insulating properties and superb adhesion to virtually all building materials.
