Help keep your tarps, rainwear, and family-sized tents free from troublesome leaks and drips with the Gear Aid Seam Sure Liquid Seam Sealer. This water-based urethane seam sealer is ideal for polyurethane coated fabrics. It has a flexible, odorless, and long-lasting formula with a nearly invisible non-gloss finish. At room temperature, the fast-drying formula cures in just 2 hours (longer if colder). The unique applicator brush makes it easy to cover large surfaces, and the 2 oz. tube seals seams about 288" in a 1/2" bead - the average amount for the critical seams on an average 3 to 4 person tent.
