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.
