Seam Grip WP Waterproof Sealant & Adhesive (28g)

Gear Aid Seam Grip WP is a waterproof urethane seam sealant and repair adhesive for polyurethane-coated outdoor fabrics — the correct choice for standard nylon tents, canvas tarps, awnings, vinyl, and polyester gear. One 28g tube seals up to 3.66 metres of seams, cures to a clear, flexible rubber bond, and doubles as a repair adhesive for holes, tears, and fabric failures across a wide range of outdoor equipment.

• Urethane formula for PU-coated fabrics — Seam Grip WP is specifically formulated for polyurethane-coated fabrics including standard nylon tents, canvas, vinyl, and polyester; it bonds permanently to PU-coated surfaces where silicone-based sealants will not adhere effectively.
• Seals up to 3.66 metres per 28g tube — sufficient for sealing the key seams on most standard tents, tarps, awnings, and camping shelters; also available as a 7g two-pack for smaller repair jobs.
• Waterproof and permanent — provides a water-tight seal that resists peeling and cracking over time; maintains its integrity through sustained rain, UV exposure, and temperature variation.
• Cures to a flexible rubber seal — the cured sealant stretches and moves with the fabric rather than cracking under tension; essential for shelters that are pitched, packed, and repitched across a season.
• Repair adhesive for holes and tears — in addition to seam sealing, Seam Grip WP bonds fabric panels and patches together and can be used to repair tears, holes, and delamination in nylon, vinyl, leather, canvas, and polyester gear.
• Abrasion resistant — the cured bond withstands scrapes and surface wear, making repairs hold up in high-friction areas of tents, awnings, and outdoor equipment.
• Bonds to PVC plastic — suitable for use on PVC plastic components as well as fabric, covering a broader range of gear repair applications.
• Dries clear — cures to a transparent finish without visible smears or discolouration.

Important: Seam Grip WP is designed for polyurethane-coated fabrics. For silicone-treated (silnylon) tents, tarps, and ultralight packs, use Seam Grip SIL — silicone coatings will only bond to silicone-based sealants.
