SEAM SURE Water Based Seam Sealer is a fast-drying, water-based urethane formula designed for sealing sewn seams on synthetic fabrics and breathable laminates. SEAMSURE dries to a clear, flexible, long-lasting film with a nearly invisible non-gloss finish. Ideal for waterproofing tents, packs, rainwear, garments, tarps, and more.

SEAMSURE flexes with the fabric ensuring waterproofing even in cold temperatures and high wind conditions.

Our unique brush applicator allows the user to easily apply SEAMSURE into needle holes, sewn joints, corners, and under lap-felled and folded seams.
