## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by B***N on May 16, 2025*

Worked great, was easy to apply. Great product.

### ⭐⭐⭐⭐⭐ If you tent is leaking at the seams you need this.
*by C***  on July 28, 2025*

My 2 man 2015 tent had starting leaking and I notice that the water drops were coming from the seams of the fly. After checking reviews and you tube videos I purchased a tube of Seam Grip. I used a syringe with small tip to apply it on the seams and then spread it with the little tool the sealer came with. I sealed all the seams on the rain fly of the tent. It worked PERFECT! It dries clear. I now have a tent that I trust again in the rain.Carmen

### ⭐⭐⭐⭐⭐ 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.
