Restore polyurethane (PU) coating to like-new condition with Seam Grip TF. Previously known as Tent Sure, this clear sealant makes tent waterproofing hassle-free with its built-in foam applicator brush. Over time, the protective waterproofing on a tent floor, rain fly, or tarp wears out and begins to flake off. Easily apply Seam Grip TF to the fabric and treat up to 85 sq ft of material to prevent gear from leaking with only one 4 fl oz bottle. When a rainfly gets sticky or backpacks start delaminating, make them perform again with Seam Grip TF Tent Fabric Sealant.
