Board Seam Filler WB 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,

Board Seam Filler WB 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.
