GEAR AID Seam Grip WP Waterproof Seam Sealant & Adhesive, 1 oz Tube 2-Pack — Flexible, Durable Repair for Tents and Tarps

Seam Grip WP is a flexible, waterproof urethane adhesive that permanently seals seams and repairs rips on tents, tarps, awnings, and outdoor fabrics.

Stopped-up seams, tiny punctures and worn-out waterproof coatings don’t have to end your trip. GEAR AID Seam Grip WP is a compact repair tube designed to restore water resistance and structural integrity to fabrics like nylon, polyester, canvas and vinyl. This 1 oz tube treats up to 12 feet of seam or patching work and cures into a durable rubber seal that moves with the material.

How does Seam Grip WP mend torn fabric and leaking seams?

Seam Grip WP bonds to synthetic and natural fibers and fills gaps with a waterproof urethane that remains flexible after curing. The adhesive forms a continuous rubberized layer that bridges holes, seals needle perforations and reinforces stitched seams.

• Applies smoothly to nylon, polyester, canvas, vinyl, leather and coated fabrics.
• Cures into a flexible, waterproof seal that resists cracking and peeling.
• Includes an applicator brush for precise placement and neat repairs.

How much area will one 1 oz tube cover and when should I choose the 8 oz size?

One 1 oz tube is engineered to seal up to about 12 feet of stitched seams or to patch several small tears. For larger tarps, full seam reproofing or multiple gear repairs, the larger 8 oz size is more economical and reduces the need for frequent reorders.

• 1 oz treats approximately 12 feet of seam depending on seam width and thickness.
• 8 oz recommended for bigger tents, tarps, RV awnings or fleet gear maintenance.
• Buy a 2-pack of 1 oz tubes for field backups or multiple quick fixes.

Can I use Seam Grip WP in the field and how easy is it to apply?

The tube and included applicator brush make field repairs practical and clean, even in damp conditions. Surface prep is simple—clean and dry the area as much as possible—then apply an even bead, smooth it to cover the damaged area, and allow it to cure per instructions.

• Compact 1 oz tube fits in repair kits and packs for on-trail fixes.
• Applicator brush enables controlled application on seams and patches.
• No specialized tools required; follow cure time on the label for best results.

What materials and gear are compatible with this sealant?

• Bonds to nylon and polyester fabrics common in tents and rainflies.
