GEAR AID Seam Grip FC Fast Cure Sealant for Sealing Seams on Tents, Rainflies, Shelters, Awnings, Tarps and Pop-ups Made of Nylon, Vinyl, Clear, 2 fl oz

This stuff works great and holds. I find this to be very easy to apply and dries fairly quickly. Great value

Great for shoring up fabric seams that leak in rain or weather, to far seems to work well and easy to apply

I used this on the seams of our canopy to waterproof it for our camping trips. The application process was messy...the bottle leaked, a lot, when rubbing the brush along the seams...however, the seal was extremely effective. It rained twice on our trip and everything under the canopy stayed perfectly dry. So you'll need patience in using this applicator, but the result is worth it!

I got caught in a torrential downpour in Hawaii, and my 20 year old Sierra Designs tent that had never leaked let a puddle accumulate. I used this on the fly and the base of the tent, and it stayed dry with a solid hose test and in a fairly strong (but brief) rain last weekend camping. In all fairness, I also re-coated the fabric, so I'm not sure which had the leak to begin with. The other reviews really trashed the applicator, so I wanted to say my piece on that. I felt like it worked ok. Not great, but ok. If you want your seams to look perfect, maybe use a small sponge applicator (maybe from the paint section at your hardware store or something from an art store). For a garment, this may be too messy. For a tent, it was fine. I just used a moist rag to clean up a few drips and runs. It wasn't factory-perfect, but it was good enough for a tent. Instead of ripping off the seal on the bottle, try puncturing it finely. I ripped it off and felt like the applicator tip was fine, but the flow of liquid was too fast, leading to drips. If I could have slowed it down, it would have been much better. Also, use a strong headlamp. The more light you have, the easier it will be to see what you're doing. I did this in a carport on a fairly dark day. I was ok doing the rain fly, but when I went inside the tent, it was too dark. When I added more light, I found it was a lot easier to get the right amount of liquid on. In the dark, I was over-applying, and it was messier. Note that the bottle has some scary health messages about this, so use caution. I put on safety glasses and rubber gloves to apply.

I was honestly skeptical and this did create insane amount of mess but.. ... I've never seen a tent condensate so much and I attribute a lot of that to the fact that when I sealed these seams..... They were freaking sealed

So, I have used this product before to seal seams for anything from my tent to my kids' leaky bouncy house, which I have included pictures of both. I have used both the Fast Cure Gear Aid and the Gear Aid WP. When it comes to preference and performance, I am going to say it depends on the job. I'll explain: First, there are no two ways about it, this stuff takes some patience and practice to cleanly apply. I've learned that there are no easy shortcuts to the process itself, only sloppy and properly prepared with right expectation. Second, the amount if time spent applying and allowing to cure should vary by the need of the project. With my kids' leaky bounce house, I took no more than 5 minutes to run over the seams with the Gear Aid FC, and then maybe another hour to allow it to dry outside. The job wasn't pretty, but it didn't need to be and it got the job done. No more air leaks, and no more whining kids. Win win situation. For my tent and camping gear, though, I took about an hour or so to prepare and apply the FC seam sealer to the inside of my tent and both sides of my rain fly (a bit overboard on the double side of the rain fly, yeah, probably, but if you have ever slept in a wet tent before you understand the OCD overkill). The job came out beautiful (pic included of inside seam of my tent and outside seam of my rain fly in a torrential downpour... a downpour that lastd for seven very, very long wet days; however, inside my tent, it was dry as a bone. I'd take 10 hours to do the job right with this stuff to get those kind results. I'll explain my steps on the tent seam application for those interested, but first let's go over the quick list of pros and cons for those not so interested. Pros are, 1) this stuff works, when applied properly 2) can be done quickly, though more messy, for those kind of jobs where messy is okay 3) little goes a long way, so you can make it last if applied with some care and preparation 4) can be used on multiple types of projects 5) not overly expensive, especially if it keeps you from waking up in a soaked sleeping bag with a puddle of soon-to-be-pond rain or ground water filling the corner of your tent 6) good to use on multiple types of fabric Cons are, 1) messy to use, especially the first few times of learning how to apply 2) not as heavy duty a sealant as the Gear Aid WP version (which is urethane based sealent designed to act as an adhesive and permanent water sealant solution; FC is a water-based sealant that applies thinner, quicker, without adhesive qualty) 3) will not seal seams that already have too large a gap or tear. If that's all you wanted to know, then cheers! And best of luck with your project. If you are interested in how I went about sealing my tent, I will make it quick, but read on! Tent preparation and application steps, 1) I set up my tent and hung my rain fly out seperatly, stretched tight, so I could access both sides of the tent and fly 2) I applied a healthy application of Scotchgard Heavy Duty Waterproofing spray and let dry for 30 minutes (may need longer time to dry if in more humid or cold environment); love that stuff, and I have written a review on that product as well if interested in that type of product (note: pic of tent in rain included is my rain fly with both the Scotchgard and Gear Aid application 2) lay out material as flat as possible in a dry space and be sure cornors are stretched tight and secured (I used some twine to loop through the cornors and a few tent stakes to tie off to) 2) I ran blue painters tape alongside existing manufacturers seam sealant to create clean, straight lines because I have some serious make "my eye sort of twitch" issues when it comes to straight lines and clean work for the type of projects that matter to me...and I am totally okay with that 😁 3) I poured the Gear Aid FC into a disposable container, like other users have suggested, and applied to seams using a 1/2 inch wide brush 4) I let it sit for about 3 hours (an hour over recomended cure time) And the result...could not be more happy! I love the FC because it is quick to apply, does not have any tendency to peel off as WP formula does, due to FC being a water-based formula, and because it works. No matter the seam sealer or waterproof spray or weather resistant application you apply, you will always have to reapply it at some point in the future -- we try, but people never win against Mother Nature given time and circumstance. Good luck on your project and purchase decision. Cheers!

Sealant appears to be of a fair quality. The applicator is horrible. There is a lingering after product use Smell that seems to linger for a very long time after application to my tents which is very anoying, even after ample ventilation post application. Because of the smell, I'd look for another product.

I have not got to “field test“ it yet but from the application it looks like it should work just fine. The seam grip is super easy to apply but prep work it is a little bit of a process, removing all of the failing seam tape (which in my case was the entire rain fly and tent bottom), cleaning the seams with rubbing alcohol, and them letting treated seams dry completely before moving to another seam. The seam grip spread very easily and definitely seemed to penetrate the seems.

Très efficace attention une seule petite bouteille à la livraison pas deux comme sur la photo avec une j'ai fait toute ma tante avant l'application j'avais des fuites partout après l'application plus de fuite petit tuyau ne vous en mettez pas sur les mains vous allez avoir une pellicule de caoutchouc

Works as stated.

Logró sellar gran parte de la costura del sobre toldo de la tienda y no goteó para nada

Habe damit die Nähte meines Event Shelters bearbeitet mit den Maßen 4,5m x 4,5m und einigen Querstreben, also 20m locker und das Fläschchen ist noch mindestens halb voll. Der Pinsel hat sich super gemacht, die Tinktur ist sehr schnell eingezogen.

Llego bien. Todavía no lo hemos usado
