Be sure to pre-tension prior to applying

I used this to seal the seams of a Big Agnes Copper Spur 2 rainfly. I have yet to put it to the test in rainy conditions; time will tell how well it actually seals. Based on visual inspection, it dries flat and bonds well once it has had sufficient cure time. As noted by other reviewers, it can be messy to apply and begins to set quickly; you may want to buy extra brushes. It helps if you work fast with one small bead at a time on the brush rather than trying to squeeze a large glob from the tube directly on a seam and then brush it into place. Another tip is to use that blue masking tape that peals off easily to mask your seams. It makes for a much cleaner and more even application. Lastly, when sealing anything flexible, pull it taught prior to applying the Silnet. This way the Silnet is applied to the item when it is under its greatest tension. If you apply the Silnet without doing this step, then when you go to tension the item in actual use you will either (a) be unable to tension the item to its intended configuration because of the resistance of the Silnet or (b) tear the Silnet and/or a seam. For example, I set up my rainfly over the tent poles just as if I was setting up the tent for real-world use. Then I applied the Silnet. Even with this extra precaution, my rainfly is now even more difficult to pull into position over the ends of the central cross-member due to the extra resistance of the Silnet. Had I not pre-tensioned it prior to applying the Silnet, I probably wouldn't have been able to get the rainfly to fit over the pole ends at all or it would have torn trying to do so.

Need a larger tube size!

Seems like a good product; won't be sure until next time we use the tent. However the tube size is really too small to fully seam seal even our modest size two person tent. I ended up needing to buy two rather pricey tubes. Suggest a larger tube size that is 2 1/2 oz. or more as being more realistic for a full seam sealing job.

Excellent Product

One 1.5oz tube sealed all factory sewn seams on a Marmot Limelight 2P tent rainfly when applied moderately. Simply pitch the tent, install rainfly inside out, and apply.

Works: wish I'd followed different instructions

8 years ago

This stuff does work well and cures quickly. However, not the easiest thing to work with. The included brush isn't the best tool. I found a stiff cheap craft brush from Michael's did a better job getting it into the seams. It sets up quickly. If you squeeze this out into another container you will waste product because it gets too thick to work with. Squeeze a tiny bit at a time onto brush. I was sealing a single wall tent and when doing bathtub seams from inside tent I was quite high on the fumes from this stuff. It took me a couple of hours to completely seal the fly and tub of my solo tent following the instructions on the package. I later found out that this can go much quicker, use less product and look neater if you dilute the product with mineral spirits and apply with a syringe or a foam brush. Oh well, it's done. Live and learn,

Works Great

16 years ago

I used this to seal the seams on my pack cover,and it worked great. 2 days of wet snow while backpacking on the NCT and my osprey stayed dry. Perfect for use on tents as well. TIP: you may want to buy a couple of extra brushes(available at any hardware store) and work quickly. This stuff sets up fast and starts to solidify on the brush making it difficult to work with.

Seam sealer

15 years ago

Awesome stuff. Sealed a stuff sack and decided to put some on my boots just to see what would happen. It's now pretty much bonded to the boot rubber. Only issue is that it is messy, even with included applicator brushes but even with that it's not too bad. It's not sticking to the surrounding stuff sack fabric but is stuck to the seam threads. Also, needs a couple days to dry properly as it stays tacky for a while.

Sil Net application

10 years ago

Applying Sil Net requires following written directions. Use the syringe applicator and a brush. Some reviewers here complain about messy, pull apart results, and long dry/cure times. This is poor application. Be careful. Read and follow the directions. if you do this it is a great product. I have used it for major whitewater raft gear, major Himalayan trip gear, and numerous silnyl (sp?) products. Go for it, folks.

This does exactly what it says it will.

11 years ago

This product does exactly what it says. It takes a while to apply, but it is worth it. I stayed up late one night waterproofing a bivy, and now it is basically a fort knox when it comes to keeping weater out. The only issue was that the brush gummed up pretty fast, but that was not even a problem.

Durable seam sealer for silnylon

8 years ago

I use this to seal ridge seams on my DIY tarps for hammock camping. This is such an important seam to keep water out as it is directly above me, and gearaid seam sealer has never let a drop in. It has held up in the worst downpours and strongest winds I've ever camped in even after 3 years of heavy use. It has also been used to patch a small hole in my tarp, again with no leaks whatsoever. It's easy to apply, just be patient.

Keeps boot seams from failing

6 years ago

Although this is tent seam sealant, I use it to protect the seams on my boots. It keeps rocks and other debris we walk through from damaging the stitching on the boots so the seams don't fail. I run a thin bead over the outside of each of the seams on the boot. Work great.
