Seam Grip FC is a fast-curing, water-based tent seam sealer. Previously known as Seam Sure, this waterproofing sealant comes in a 2 fl oz bottle and seals up to 60 ft of seams or fabric. The liquid formula is perfect for family-sized tents, tarps and pop-ups made of nylon. Just apply a thin film to the inside seams and allow to dry to a clear, flexible seal. Don’t let rain ruin an outdoor experience. Seal and waterproof tent seams in no time with Seam Sure FC and stop leaks before they happen.
