The Gear Aid Seam Grip SIL is designed for sealing any kind of gear that has a silicone finish on it. That includes tents, backpacks, tarps, anything silicone treated, to be honest. It’s also very light once it cures so if you’re into shaving ounces off your gear, this might be the sealer for you.
The tube gives you 1.5 ounces of sealant that will cover up to 24 ft of seams if you use it appropriately. Using it is a little tricky due to the thickness of the liquid but once it’s applied correctly you’ll end up with a windproof, waterproof seal that can pretty much handle anything.

Coleman’s Seam Sealer is designed for use with tents, tarps, backpacks, and more. It is just a seams sealer though and is not great for patching up a gear, so it’s not an all gear puncture repair kit like some of the others.

The seal will be able to handle being washed and even dry cleaned, so no matter how you clean your gear, the seams will remain sealed.

Only applied, it takes 4 hours to cure but 24 hours to dry. It can be used on the trail with ease but be careful if you’re changing camp after the 4 hour period. Once it’s dry it’ll be waterproof, flexible, and last a long time.

As you can see from all the tent seam sealers in the review, they are all effective over certain materials. Make sure to buy a sealer that matches the material of your tent so that it can be as effective as possible. The sealers in the review cover nylon, polyester, canvas, silicone-coated fabrics, and more, so they should have you covered.
The thicker the sealer the harder it is to apply but the coating is usually a bit more robust, so the choice here is up to you. Thinner sealers are much easier to apply but they can begin to drip while you’re applying them at height. Either way, you’ll most likely end up having to get used to whatever thickness you end up choosing so I wouldn’t worry about it too much.
Seam sealer is usually applied in one of two ways, either painting, foam applicating, or spraying. Most of the sealers in the review are paint-on sealers that allow you to get detail orientated about but it does take some time. Spray-on sealers are a lot easier to use but you may end up wasting some in the process. Foam applicators are pretty much pain brushes but a little easier as you’re rubbing instead of painting.
Think about how much tent seam sealer you’re going to need and buy the appropriate amount so you don’t run out halfway through. It’s always worth buying an extra one or two as they are not very expensive. If you have a small tent then one small tube will probably be fine but if you’re doing a big tent make sure to get a bottle that is atleast 4 ounces.
The best tent seam sealer, if you’re on a budget, is the Coleman Seam Sealer. It’s an all-purpose, water-based, eco-friendly seam sealer that dries in just 2 hours.

The all-round best tent seam sealer is the Gear Aid Seam Grip FC. It’s designed for use on canvas, polyester, and nylon so it’ll work on pretty much any tent you need it to. It’s also reasonably affordable, cures quickly, and is well worth keeping in your backpack for use on the trail.
The best tent seam sealer is the Texsport Polyurethane Waterproof Seam Sealer. This seam sealer does everything you could ask from a sealer.
