GEAR AID Seam Grip WP Waterproof Sealant and Adhesive for Jackets, Tents, Sleeping Pads and Outdoor Fabric | Repairs Rips, Seals Seams on Nylon, Canvas and Vinyl

I will buy this again

I used this to seal the seams on my boots, it dries quickly and makes a industrial level seal where every it is applied!

Works amazing I usually use gorilla glue for the stitching on the insides of backpack as well as the water proofing material but usually it has flaked off after awhile, but this definitely works better as it forms a silicone layer instead of a plastic like material, used it on the flaked patches of water proofing material inside my backpack and it looks and works good as new. Only complaint the tube of sealant I was using did have a small puncture form after a few minutes of using “could’ve been my fault some how” wasn’t a big deal as I just left it there to dry and the sealant just sealed itself lol. Also it comes with one brush for the two pack and it’s basically impossible to clean as no amount of alcohol or water can easily take off the sealant to reuse the brush.

Seems to have sealed up my 104 degree hottub cover seams very well, BUT will see how it performs as the Arizona heat reaches up to 120 and the hottub temp reaches 112 (before I cool it down).

My 20 yr old camping tent was leaking and I removed all seam tape and applied this on the seams and after curing not a single drop of water came through. Be sure to wear gloves when using this as it is difficult to remove from hands. You can get it completely off once it’s cured.

Nothing else like it!

People are drama queens or just cannot follow instructions. I've used this product and other GearAid products like Aquaseal on tents and breathable fishing waders, and I've even repaired holes in jackets with this product. I've also done emergency repairs on two tents damaged in a tropical storm. This can be a bit of a challenge to apply, moreso because of the space needed to hit all the seams in a tent or rainfly, and the time it takes to cure.One, use this product on a CLEAN garment or item. Really. Clean the fabric with Nikwax Tech Wash or at minimum, alcohol prep pads. Make sure it's DRY before applying.Two, take your time with this application. Put a thin coat on over the stitching or seam joints.Three, if you're using this as a patch in conjunction with Tenacious Tape, you need to have an overlap of at least 1/2 to 3/4" on any side of the defect/hole/tear so there's some healthy material that the patch can seal onto. The Tenacious Tape instructions are very clear about this. Cut the tape to fit around the shape of the defect.Four, plan for leaving the garment/item in place and not moving it until the curing process is done for 8+ hours. For a large tent, rainfly or waders, this will likely mean that you will need to do the seam sealing in stages. Otherwise, the newly painted seams will stick to each other or your item's non-seamly bits and make a HUGE mess, possibly destroying the item entirely. Still, I'd recommend putting a light dusting of some talc/baby powder on the seams/repair prior to stowing the garment/item so you don't have any sticking together.Lastly, once this product is opened and exposed to the moisture in the air, the countdown to it becoming hard and unusable starts. Get as much use as you can from the brush/applicator. Once the sealer dries, , it will harden and not be very useful. I wipe the threads clean to keep the cap from getting jammed, then put the tube of seam sealer in a ziplock and stow it in the freezer. Run it under a hot water tap for about a minute or two and the product should still be flexible and able to be used. I may get a season or two use out of a tube, but the applicators are pretty much done after one use. After that, I use popsicle sticks to smooth the product on. You can even reapply over a previous patch to re-seal an edge. They claim these types of products have a 4 year shelf life but that really depends upon the storage conditions.

I followed the steps outlined on the Gear Aid YouTube tutorial. To start with, gloves are a must! They suggest taking off the existing seam tape if it’s in rough shape. Mine was practically new, so I tried the seam sealer over it — and it turned out mediocre at best. The sealant is extremely sticky to the touch, and it is like a magnet for sticking to itself, so if you don’t already have talc at home go ahead and add some to your cart. If you don’t use talc you are guaranteed that your new seams are going to stick to themselves, and if you left the seam tape on, it’s going to undo all of your hard work. We will see how it foes at keeping the rain out this weekend on my rainy backpacking trip. I had about a half a tube left after sealing my poncho. The instructions say to put the remainder in the freezer, but there’s no mention of how to clean the brushes after.
