Use Seam Grip TF as a tent sealer to restore the polyurethane coating (PU) on a tent floor. Over time, tent waterproofing wears out and begins to flake off. Previously known as Tent Sure, a 4 fl oz bottle of Seam Grip TF restores tent floors to like-new condition and treats up to 85 sq. ft. of material. With its built-in foam applicator brush and non-toxic formula, seam sealing is safe and hassle-free. Easily apply it to any synthetic fabric you want to waterproof such as a rain fly, rain gear, awning or boat cover. When tent flies get sticky or seams start peeling, make them waterproof again with Seam Grip TF Tent Fabric Sealant.
