Rated 5 out of 5 by from Works Great 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.

Rated 4 out of 5 by from Seam sealer 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from This does exactly what it says it will. 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.

Rated 5 out of 5 by from Sil Net application 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.

Rated 3 out of 5 by from O.K. for small repairs I have used this product for two things 1; I sealed the bottom of a siliconed nylon stuffsack tu use it as a water carrier this worked pretty well 2; Tryed to repair multiple tiers in my backback patching it with nysil this worked o.k At first it was very messy getting it on the patch inside the pack. it then took overnight to get tack free and proberbly 3-4 days to reach full strenth. even with 2" overlaps the patches did not hold well they did for afew trips but when they were asked to take a real load they pulled apart.

Rated 5 out of 5 by from Durable seam sealer for silnylon 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.

Can this adhesive be used for patching silicone nylon, ala Aquaseal? I'd like to adhere a light-duty handle to a silicone/nylon stuffsack and hoping Silnet will fit the bill. Thank you!

Asked by: ajax
This seam sealer is a great choice for waterproof silnylon or silicone-treated fabrics.
