Seal Silnylon Tent Seams and Stay Dry
Seam sealing with Seam Grip SIL is the best way to keep moisture out when using a silnylon (silicone-nylon) tent. Previously known as SilNet, this clear sealant dries to a flexible rubber that works on all silicone-treated gear, including nylon tarps and ultralight backpacks. A single 1.5oz tube can seal up to 24 ft of seams. Fast and easy to use, it’s also handy for pinhole repairs and small tears.
When you need to waterproof a silnylon tent, only a silicone sealant will work because silicone will only adhere to silicone. So, treat gear right and seal out the weather with Seam Grip SIL.
Features:
• Compatible – Bonds to silicone-treated fabrics to prevent water from seeping through seams
• Waterproof – Provides a water-tight seal that won’t peel or crack over time, keeping you warm and dry
• Long-lasting – Rubber sealant seals seams and patches pinhole leaks for repairs that last for years
• Flexible – Cures to an elastic, rubber seal that flexes and stretches with high- performance gear
• Weather-resistant – Tough formula is not affected by extreme heat or cold
