Seam Grip SLI Silicone Tent Sealant

Seam sealing with Seam Grip SIL is an easy and effective way to keep moisture out of your silnylon (silicone-nylon) tent. Formerly known as SilNet, this clear sealant dries into a flexible, rubber-like finish that bonds perfectly with silicone-treated fabrics. It’s ideal not only for silnylon tents, but also for nylon tarps and ultralight backpacks that need reliable waterproofing.

A single 28g tube can seal up to 7.3 meters of seams, making it quick, efficient, and simple to apply. It’s also great for fixing pinholes and small tears, helping extend the life of your gear with minimal effort. Because silicone only sticks to silicone, a true silicone sealant is essential when waterproofing silnylon and Seam Grip SIL is designed specifically for that purpose. It creates a strong, waterproof seal that won’t peel or crack, stays flexible as your gear moves, and holds up in both extreme heat and cold. Seal out the weather and take care of your gear with confidence using Seam Grip SIL.
