Gear Aid Seam Grip SIL, Silicone Tent Sealant – Model 10440

No one wants to sleep in a puddle. But if you own a silnylon tent, you could end up in one—if you don’t treat the seams first. That’s because ultralight silnylon tents aren’t typically sealed at the factory.

Luckily, there’s Seam Grip SIL, a silicone seam sealer previously known as Sil Net. It’s fast and easy to use. The silicone adhesive in Seam Grip SIL waterproofs silicone tent seams with just one application. The exclusive formula is not affected by extreme heat or cold. Plus, it comes in handy for repairs on moderate rips and tears.

When you need to waterproof silnylon or silicone-treated fabrics, only a silicone sealant will work. Seam sealing with Seam Grip is the best way to keep the elements outside—where they belong.
