Bridge sheathing and penetration gaps up to 1" and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components. Suitable for all climates, Joint & Seam Filler bonds directly to damp or dry surfaces and cures under a variety of weather conditions. Dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners. May be fully exposed to UV and weather for up to 12 months. Solvent-free. Isocyanate-free. Phthalate-free. Passes ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials. LEED, Living Building Challenge and Cal Green Ready. This item contains 4 single sausages Joint & Seam Filler is a gun-grade crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, silyl-terminated polymer (STP) is easy to gun, spread and tool. Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge larger gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components. Suitable for all climates, Joint & Seam Filler bonds directly to damp or dry surfaces and cures under a variety of weather conditions. It dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners. Use Joint & Seam Filler as part of a continuous, building-wide air barrier system, or to prepare surfaces for conventional waterproofing or air barrier components.
