OSI GS121 Gutter & Seam Sealant

OSI GS121 Gutter and Seam Sealant White, 5 fl oz

• Permanently flexible
• Water resistant seal
• Seals most common gutter and downspout materials
• Expands and contracts with temperature changes

The OSI Gutter & Seam Sealant is specifically designed for use on gutters and downspouts. When applied, a tough, flexible, and rubbery seal is made to allow for movement during the seasons. This feature can prevent cracking that can happen with other sealants that are exposed to a cold winter and a hot summer. This sealant is best for aluminum, galvanized, and vinyl clad gutter and downspout systems.
