Seam Grip WP is a urethane seam sealer that goes a step further than most: it does not just seal seams, it also works as a flexible repair adhesive. One 28 g (1 oz) tube seals up to 3.5 metres (12 ft) of seams on tents, tarps and awnings. Once cured it forms a permanent waterproof seal that flexes with the fabric and does not peel or crack over time.
The same tube patches holes and tears in almost any outdoor fabric: nylon, polyester, vinyl, canvas, leather and even PVC. So take it along on your next trip and you are ready when something rips, leaks or falls apart. Even a spot where up to 3 cm² of material is missing can be filled with Seam Grip.
What Seam Grip WP does
- Durable: tough urethane formula that bonds permanently to tents, awnings, campers and PVC plastic
- Waterproof: a watertight seal that will not peel or crack
- Flexible: cures to a thin rubber layer that moves with your gear
- Abrasion resistant: repairs that survive scrapes and scratches
- Multipurpose: bonds with nylon, vinyl, leather, polyester and more
What can you repair with it?
Cracks and holes in backpacks, tents, clothing, footwear, air mattresses, leather, tarps and groundsheets. Seam Grip stays elastic, does not dry out and is not porous, so the repair lasts.
Tip: want to keep an opened tube for later? Put it in the freezer. It stays usable for months that way, so you do not throw away half a tube after one repair.
