## Overview

GEAR AID Seam Grip TF is a 4 fl oz water-based polyurethane tent fabric sealer designed to restore and waterproof nylon tent floors, rainflies, and tarps. Covering up to 85 sq. ft. per bottle, it dries to a flexible, nearly invisible coating that prevents leaks and extends gear life. Featuring a built-in foam applicator, it offers easy, precise application for durable, long-lasting protection against the elements.

## Description

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.

Review: This stuff was easy to use and apply. Our tent was starting to leak and we applied it to the inside of the sides and the floor plus the inside of the fly. We have a big 6 person tent and went through about 6 bottles (don't be fooled by the label saying you need way less). It is a bit of a pain in the butt to apply this to a large tent but did it ever make a difference. Totally worth it. You can barely tell it has been applied. It didn't leave a weird coating on the tent or anything. Make sure you have enough time to do the whole thing in one or two sittings and you track what part you've already done because it is hard to tell where you've already been once it starts to dry (which is quick) so you need to have a system to track that. I definitely did at least one section twice because of this. It helps to have a second person who can hold up a board or something on the outside of the tent while you "paint" on the product if using it on the sides. The floor is easy to do and I suggest you take the fly off and lie it down on clean groud before you do that. I followed instructions on the REI website on how to re-waterproof a tent and started by cleaning it in my bathtub first. Glad we will only have to redo this every few years.
Review: I was extremely hesitant to buy this, based on the multitude of reviews that claimed it was very difficult to apply, and Gear Aid's coverage claims are a lie. But I figured I'd give it a try before buying a new tent. Gear aid is correct. It covers an incredible amount of surface area. It is easy to apply. I used a single bottle to refresh an entire tent. I did the floor in about 40 minutes. I did the rain fly of a tent in about an hour. There's still a little bit left in the bottle. The best strategy is to use short 4-6 inch strokes, pushing the bottle away from you. Just keep moving over inch by inch, and cover the area, then back up and do the same thing again. You'll see the surface gets slightly damp that you've treated. It starts to dry relatively quickly, and sometimes can be hard to see where it's already been treated because of that. I haven't yet sprayed down the tent to see efficacy, but the old coating was still mostly effective so that won't be definitive. And from the small amount of liquid on my fingers, which dried into a polyurethane coating, seems pretty clear it works. Buy it, treat your gear, and enjoy. It's slightly tedious, but not hard. All you're doing is getting the surface slightly damp. You have to make sure to keep pressing the bottle down and squeezing a little bit during your strokes. Occasionally, stop, press down hard, and squeeze, to resaturate the sponge fully. Easy, not super time consuming, and a very inexpensive way to rehab a tent. You're painting on an extremely thin layer which closes the pores of the fabric and makes it waterproof. You are not putting down a multi-millimeter layer of polyurethane. Those people who claim it uses seven bottles, or four bottles, and that you need a paint brush, don't understand how DWR works. Think about the last waterproof jacket you bought, or your tent when it was brand new - it did not have a multi-millimeter thick layer of polyurethane on it. It looked and felt like fabric, and invisibly had a DWR coating on it. That's what you're restoring. That's what this does. And the sponge applicator allows out exactly the right amount of liquid.

## Questions & Answers

**Q: Is this a good product for resurfacing a tent floor? If so, should I do the whole floor or just the areas where it's clearly peeling?**
A: Yes, it can reseal a tent floor, but my experience is that the product directions do not yield good results. I recommend first washing the tent floor (bathtub and dishsoap), rinsing well, and thoroughly drying. Next, wipe the floor with a rag dampened with alcohol (do not use rubbing alcohol which contains oils), and remove all old sealant that is peeling. The alcohol will turn areas that are not sealed dark, note these areas. Apply the Tent Sure with a clean microfiber cloth wiping it on as thin as possible, working in small areas. Let dry 24 hours, then recoat with very thin applications using the cloth. Multiple thin coats are far better than one thick coat. I've had excellent results with tent floor and fly using this application method. Using the built in applicator to apply the product results in a thick, sticky mess with less than advertised coverage. It is possible to apply Tent Sure just to spot areas, but my experience has been it is better to completely reseal the entire surface. Hope this helps.

**Q: Can this be used to restore the inner coating in backpacks?**
A: Absolutely!  This water-based product is a wonderful sealant traditionally designed to be used on tents ... but it works wonderfully well on many other fabrics to include the inner fabric of a backpacks!  In fact, I recently used this product on one of my old backpacks.  Of course to work its best, you must first remove any deteriorated waterproofing that may exist from your backpack inner fabric.  Once the material is clean and dry, you may apply the Tent Sure product on the fabric.  For added waterproofing of your backpack fabric ... I also recommend applying a spray type waterproofing to the outer fabric too!   There are many types of spray waterproofing available either online or at good camping supply stores.  I hope this helps you!  Happy New Year!  K.C.L.

**Q: can this be used on old jackets?**
A: Sure, anything that is no longer keeping water out.

**Q: Kelty customer service recommended this for my tent bottom.  Do I apply inside or outside, or both?**
A: Thank you for your question. The directions on the bottle recommend you apply it to the inside of your tent.
