## Overview

GEAR AID Seam Grip SIL is a premium 1.5 oz silicone sealant designed to waterproof and repair silicone-treated silnylon gear. It seals up to 24 feet of seams with a flexible, durable, and weather-resistant bond that won’t crack or peel, making it ideal for tents, tarps, backpacks, and rainwear. Trusted by outdoor pros, it ensures your lightweight gear stays dry and protected through all seasons.

## Description

When you need to waterproof a silnylon tent only a silicone sealant will work. Seam sealing with Seam Grip SIL is the best way to keep moisture out. This clear sealant dries to a silicone rubber that works on all silicone-treated gear such as a silnylon tarp or backpack. One tube seals up to 24’ of seams. Fast and easy to use, it’s also handy for repairing pinholes and small tears. Remember: only silicone will adhere to silicone, so treat your gear right with Seam Grip SIL.

Review: This proved useless for fixing cuts in silicone. It does not bind with the silicone, and so didn't serve the purpose I got it for, fixing a leak in a water bladder. However, it's useful for everything else. I've used it to apply a protective coating around a screw under my table that was brushing against my leg, and to add drops to a bag's shoulder handle, making the handle grippier on my shoulder.
Review: I used this to seal my tent. Worked perfectly but it definitely took a awhile. I think it was worth the savings instead of having the manufacturer seal the tent for me. I also didn't have any issue with the seams sticking to each other once I put the tent back in its stuff sack. No leaks so far after a year of use (4 trips). I would also recommend a few dots of this on the bottom of a sleeping pad to prevent sliding on the tent floor.

## Questions & Answers

**Q: do you have to apply on both sides of the seam or just one side? also if it's one side, is it the inside or outside? thanks!**
A: Hello,

Thank you for the question. For the best seal I would recommend applying to both sides. Apply one side allow it to dry and then apply the opposite side. 


Please let us know if we can further help in any way. 

Thank you,

**Q: How many tubes would be needed to seal a 2-person sil nylon tarp? It has a ridge seam and two "gable end" seams.**
A: One tube should do the job, unless you really goop it on thick and heavy.  I have been working on a rainfly for a 4-person tent.  It has many seams so I had to get a second tube.  A two-person, simple tarp should pose no problems to cover with a single tube, IMHO.

**Q: Will this work on an older tent to seal the seams?**
A: Hello Buzz,

This sealant is designed to seal up seams coated in silicone which occurs on most tents. I would double check that your tent has silicone treated seams but it most likely would work without any issues.

Please let us know if we can further help in any way. 

Thank you,

**Q: Can I use this to adhere screen mesh to patch a 4 inch hole in the mesh portion of a lightweight tent?**
A: I think it would work fine. Down side is that there is not as much surface area for the adhesive to bond to.  I personally would hand stitch the patch to the screen and then go over the stitching and the overlapping portion (border) of the patch with the Seam Grip.
