Seam Grip SIL is the ultimate solution for keeping moisture out of your silnylon tents. Formerly known as SilNet, this clear sealant dries into a flexible rubber, perfect for all silicone-treated gear like nylon tarps and ultralight backpacks. A single 1.5 oz tube can seal up to 24 ft of seams. It's fast, easy to use, and great for fixing pinholes and small tears. Only a silicone sealant can waterproof a silnylon tent as silicone adheres only to silicone. So, protect your gear and keep the weather out with Seam Grip SIL. This self-leveling, silicone-based sealer is ideal for silicone-treated products and silnylon fabrics. It's washable and can withstand extreme temperatures. Ideal for ultralight tents, tarps, packs, and garments, a 42g tube can seal the critical seams of most ultralight two-person tents. It has a 3 - 6 hour cure time. Note that Seam Grip + SIL won't bond well with non-silicone-treated fabrics. It's made in the USA.


Using Seam Grip SIL is a breeze. First, make sure the surface of your silnylon tent or gear is clean and dry. Squeeze the sealant from the 42g tube along the seams you want to seal. It's self - leveling, so it will spread out evenly on its own. For pinhole repairs or small tears, just apply a small amount directly to the damaged area. Keep in mind that it won't bond properly to non - silicone - treated fabrics, so avoid using it on those. After application, let it cure for 3 - 6 hours. This sealant can withstand extreme cold and heat and is washable, but try to avoid washing it immediately after it has cured. To maintain your gear, you can re - apply the sealant every season or as needed to keep the waterproofing at its best. This product is made in the USA, so you can trust its quality.
