## Description

desertcart.com : GEAR AID Seam Grip SIL Silicone Sealant for Silnylon Tents and Tarps, Clear, 1.5 oz : Camping And Hiking Equipment : Sports & Outdoors

Review: Easy Application, No Leaks - 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.
Review: Worked well for seam-sealing a one-man nylon tent - Easy to use, applied it to my one-man nylon tent, which has not let any water since the application in three backpacking trips, one which involved some heavy nights of rain in the high mountains. Reasonably priced. Not sure if there would be enough product to do a two-man or larger tent. There was was a little more than I needed for a one-man tent. Recommend.

## 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.

### ⭐⭐⭐⭐⭐ Worked well on SilNylon tent
*by R***S on April 26, 2024*

I used this to reseal the seams on an older Tarptent Rainbow tent - Note I am referring to the silicone coated nylon model of the tent. This is a great tent that I have used on both the Appalachian trail and the Pacific Crest Trail. I diluted the silicone sealant to a 50/50 mix with mineral spirits before applying it with a foam brush. It applied smoothly and evenly along the seams. There are YouTube videos that will demonstrate how to mix and apply this type sealant. This tube provided more than enough sealant to reseal my tent. I am very happy with the results.
