About this product

When you need to waterproof a silnylon tent only a silicone sealant will work. Seam sealing with Seam Grip SIL is the best way to keep moisture out. This clear sealant dries to a silicone rubber that works on all silicone-treated gear such as a silnylon tarp or backpack. One tube seals up to 24’ of seams. Fast and easy to use, it’s also handy for repairing pinholes and small tears. Remember: only silicone will adhere to silicone, so treat your gear right with Seam Grip SIL.

• Durable – Tough silicone rubber adhesive bonds permanently to silicone-treated fabrics 

• Flexible – Once cured, it's an elastic seal that flexes and stretches with gear

• Waterproof – Provides a water-tight seal that won’t peel or crack over time

• Long-Lasting – Restore seam seals and make repairs that stay intact for years

• Weather-Resistant – Formula is not affected by extreme heat or cold
