Top 5 Best Tent Seam Sealers Reviews

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.

Finally, this sealant is fully cured in just three to six hours. One quick application will provide a waterproof seal that is ready to last a lifetime.

2 Coleman 2000016520 Seam Sealer

Most serious campers like to waterproof their gear every season as a preventative measure. Similarly, tents and tarps alike need to have their seams sealed when they are first purchased.

Tent waterproofer…

If you are looking to waterproof seams and corners, the Coleman Seam Sealer may be the best tent seam sealer for you. It is a water-based urethane sealant that dries to clear in several hours.

Rather than acting as an adhesive, this sealant fills in small holes to prevent water from seeping through. But, it cannot be used to make gear repairs.

Beginner friendly…

The Coleman Seam Sealer has a simple design that even beginners will enjoy using. It comes in a bottle with an attached foam applicator pad. Therefore, all you need to do is remove the top and apply the pad directly to the seams.

However, there is a catch. Instead of simply coating the seams, this formula needs to be worked into the fabric to reach its full waterproofing potential.

Lastly, this sealant comes in a two ounce bottle. As a result, it can be used for multiple applications or several pieces of gear. Although sealing seams can be a daunting task, this sealant is sure to get the job done.

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…

  • Formula

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.

  • Application

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.
