PROSOCO Joint & Seam Filler - High-Performance Fiber-Reinforced Sealant for Concrete & Masonry (4 Pack) | Ideal for Crack Repair, Waterproofing & Construction Projects

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.
