Full Fill GP is a one component, straw dispensed expanding polyurethane foam specifically designed for use in gaps, cracks, voids, and crevices in both interior and exterior applications. Full Fill GP is specifically designed to form an airtight and moisture resistant barrier which increases energy efficiency while preventing heat loss and the unwanted infiltration of moisture, air, rodents, and insects. Full Fill GP possesses excellent adhesion to a wide array of construction materials such as wood, metal, masonry, glass, and more. Designed to withstand the elements, Full Fill GP ensures gaps & cracks stay sealed during climate changes. Tack free in as little as 10 minutes. High yield formulation reduces material costs, while easy point-and-shoot installation reduces labor costs.
