Seam Grip SIL is a silicone-based seam sealer designed to waterproof silicone-treated products and silnylon fabrics. It forms a durable waterproof seal on ultralight tents, tarps, packs, and garments with a single application. The self-leveling formula remains effective under extreme temperatures and is washable. It also repairs moderate rips and tears. A 1.5 oz tube can seal the critical seams of most ultralight two-person tents. It requires a 3-6 hour cure time and is made in the USA. Note: It will not bond to non-silicone-treated fabrics.
