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. 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. Covers 38-60 ft per sausage Streamlines preparation by eliminating the need for joint reinforcing tapes. Silane functional polymer provides superior long term adhesion, crack filling and weathering characteristics. Bonds to most common building materials without priming.
