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.

Carter T. ★★★★★

Sealed the seams on my silnylon tent last weekend and the silicone went on thin and clear, no messy globs. Rained hard two nights later and not a single drip came through. Wish I'd done this before my last trip.

William ★★★★★

I put off sealing my silnylon tent for way too long, and this stuff was honestly painless to apply along the seams. Let it cure overnight and stayed completely dry through a soggy weekend. Should've done this the day I bought the tent.

Leo L. ★★★★★

Weathered three straight rainy nights on the PCT and woke up bone-dry every morning after treating the seams once. The brush applicator makes it easy to get a thin, even coat without the mess I’ve dealt with other sealants.
