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.  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 dry surfaces.  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.
