Tent Seam Sealer & Waterproofing – Seam Grip FC Gear Aid
Seam Grip FC by Gear Aid is an easy-to-use, fast-drying water-based seam sealer designed for waterproofing tent seams and outdoor shelters. Formerly known as Seam Sure, Seam Grip FC provides long-lasting, flexible, and reliable seam sealing for year-round tents and canopies.
The 60 ml bottle is enough to seal up to 30 meters of seams, making it an efficient solution for tent maintenance, tarp waterproofing, and shelter repairs. Once cured, the sealant dries clear and forms a durable, flexible, waterproof barrier that resists cracking and peeling.
