BOSS® Universal Foam is a ready-to-use polyurethane foam that is designed to expand to three times its volume when in contact with air. This polyurethane foam is ready-to-use straight out of the box and is extremely versatile. Its ability to expand fills holes, cracks, and gaps more efficiently than standard caulks, and its unparalleled insulating properties and adhesion make it ideal for all building materials.
This product is available in champagne.
Available in a 750 ml aerosol can.
