Waterproof and Seal Seams Fast

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 the rain ruin an outdoor experience. Seal and waterproof tent seams in no time with Seam Sure FC and stop leaks before they happen.

Features:

• Long-lasting  – Water-based urethane sealant is unaffected by extreme temperatures and keeps moisture out all year long

• Fast Acting   – Formula cures in just two hours for an application on tent seams that’s quick and easy

• Waterproof   – Provides a water-tight seal that won’t peel or crack over time, keeping adventurers warm and dry

• Flexible   –   Dries to a clear sealant that flexes with fabric and stays intact without flaking off

• All-purpose  – Seals nylon, polyester, vinyl, canvas, and other outdoor fabrics

Note: Seam Grip FC will not work on silicone-treated fabrics or sil-nylon. Check out Seam Grip SIL Silicone Tent Sealant here .
