Gear Aid Seam Grip WP Waterproof Sealant and Adhesive

Keeping a shelter watertight through a Canadian camping season takes more than a good tent. Seams weaken, fabric shifts, and small leaks have a way of becoming big problems at the worst possible time. Seam Grip WP is a thermoset urethane sealant and adhesive that handles both seam sealing and fabric repair in one product, giving you a genuine fix rather than a temporary patch.

A single 1 oz tube covers up to 12 feet of seams on tents, tarps, and awnings, and the permanent bond holds through washing, abrasion, and sustained exposure to the elements. The clear formula cures to a thin, flexible rubber seal that moves with the fabric rather than stiffening it, which matters on shelters that get packed and unpacked repeatedly through a season. It bonds to nylon, vinyl, canvas, polyester, leather, and PVC, making it useful well beyond tent seams for awnings, camper repairs, and general outdoor gear maintenance.

Cure time runs 8 to 12 hours with humidity as the activator, so plan applications for the night before you need the gear. Store the tube in a freezer between uses to extend shelf life. Available in 0.25 oz, 1 oz, and 8 oz sizes to suit everything from a compact field kit to a full seasonal maintenance session. Made in the USA.
