Joint & Seam Filler - Fiber Reinforced Fill Coat and Seam Treatment

Joint & Seam Filler is designed 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.

Features

• Streamlines preparation by eliminating the need for joint reinforcing tapes.
• Solvent-free. Isocyanate-free. Phthalate-free. Complies with all VOC regulations.
• Bonds and cures in wet weather and on damp substrates. Tolerates rain immediately after application.
• Silane functional polymer provides superior long-term adhesion, crack filling and weathering characteristics.

OVERVIEW

R-Guard 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.

Joint & Seam Filler may also be used to repair cracks or fill voids after the primary R-Guard air barrier has been applied.
