Gear Aid Seam Grip + SIL Silicone Tent Sealant

Seam Grip + SIL Silicone Sealant is the go-to solution for maintaining and waterproofing silnylon tents, tarps, and ultralight gear. Specifically formulated for silicone-treated fabrics, this clear sealant creates a strong, flexible rubber barrier that keeps moisture out even in extreme weather conditions. Ideal for sealing seams, repairing pinholes, and patching small tears, a single 42 g tube can cover up to 24 feet (7.3 metres) of seams—making it an essential item for hikers, campers, and anyone who relies on lightweight silicone-coated gear.

Formerly known as SilNet, Seam Grip + SIL is easy to apply and provides a long-lasting, weatherproof finish that remains flexible from -29 °C to 82 °C. Because silicone only adheres to silicone, this specialised sealant is the only effective choice for silnylon materials. Whether you’re preparing a new ultralight shelter or maintaining your trusted silnylon tent, Seam Grip + SIL ensures your gear stays watertight and ready for adventure, no matter the conditions.

PLEASE NOTE: Seam Grip SIL Silicone Tent Sealant will only work on silicone-treated fabrics or sil-nylon.
