1 Gear Aid Seam Grip SIL Silicone Sealant for Silnylon Tents and Tarps
To start off, let’s take a look at the Gear Aid Seam Grip SIL. This is a silicone sealant that is designed for silnylon tents, tarps, and backpacks.
Only silicone will adhere to silicone…
Silnylon is nylon that has been treated with liquid silicone from both sides to increase its strength. Consequently, it is a common material for lightweight camping equipment. If you are using camping gear made out of silnylon, it is important to use a silicone based seam sealer. Keep moisture out with this tough, permanent silicone rubber adhesive.
In addition, this seam grip becomes elastic once it has cured. As a result, you will have both durable and flexible seals.
Can handle all types of weather…
Another benefit of using silicone tent seam sealer is the extreme temperatures it can withstand. Often, serious campers will find that they need a waterproof tent in both very hot and cold climates. Gear Aid Seam Grip SIL is weather-resistant for wetness protection in all conditions.
But that’s not all…
This seam sealer has the added benefit of being able to repair damaged gear for the ultimate waterproof camping experience. For example, you can use it to fill pinholes and small tears.
More bang for your buck…
Although this seam sealer comes in a relatively small 1.5 oz tube, it can seal up to 24’ of tent seams. As a result, one tube should seal all critical seams on most two-person tents.

Best Tent Seam Sealer Buying Guide
Now that you have decided to waterproof your camping gear, how do you decide on which is the best tent seam sealer for you?
We have put together a guide to show you what you need to consider before making your purchase. There are many things to keep in mind when choosing which sealant to buy. However, here are some of the most important…
First, it is important to think about what material you would like to seal. If you are trying to seal anything silicone based, you will need to use silicone sealant for a permanent bond. Other sealants will do the job in a pinch. However, they will need to be replaced at some point.
If your fabric has not been treated with silicone, you have more sealant options. Water-based formulas can be very long-lasting and are often non-toxic. In addition, many water-based sealants are environmentally friendly as well.
- Bottle Size
Do you wish to seal the seams of a large tent? Or maybe you have several items of gear you wish to treat. If that’s the case, you will want to make sure you purchase enough sealant for the job.
Most of the products we have looked at come in a big enough bottle to seal one tent. However, some of the sealants come in larger bottles that are more budget friendly. If you are looking to waterproof many pieces of gear, a larger bottle is probably the way to go.
Finally, how confident are you in your sealant application skills? Some tent seam sealers come in bottles designed for convenient application.
If you are a beginner, you may find it easier to use a sealer with a brush attached. On the other hand, more experienced campers may find they prefer a tube without an applicator.
Tent seam sealers today are engineered to be durable and long-lasting. No matter the formula, you are sure to have success waterproofing your camping gear. Most importantly, you will stay dry even in the wettest conditions.
