R-Guard - Joint & Seam Filler

Joint & Seam Filler

Fiber reinforced fill coat and seam treatment

Joint & Seam Filler is part of the family of PROSOCO R-GUARD products developed to prevent the unwanted movement of water and air through building envelopes. Utilize Joint & Seam Filler to prepare open joints, seams and cracks before installing R-GUARD FastFlash; any R-GUARD Primary Air & Water-Resistive Barrier; or other waterproofing and air barrier components in new or existing wall assemblies.

Joint & Seam Filler is a high modulus, 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-Poly-Ether (STPE) is easy to gun, spread and tool.

Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge 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 building wide PROSOCO R-GUARD Air & Water Resistive Barrier system, or to prepare surfaces for conventional waterproofing or air barrier components.

Appropriate for vertical or horizontal, above-grade applications to concrete, masonry, natural stone, structural sheathing, architectural metals, painted metals, glass, PVC, FRP, EPDM and most other building materials.
