Best Budget: Coghlan’s Seam Sealer
- Most affordable tent seam sealer on the market
- Colorless and flexible; can be mashed after it dries

Whenever I’m looking for new camping gear, I always try to find the most affordable option, and that’s how I came across Cohglan’s. I’ll be honest, from the design of the bottle to the fast cure times, this sealer is incredibly similar to the next one on the list, and it’s a heck of a lot cheaper!

Hands down the best fast-curing seam sealer on the market, this option from GEAR AID has been a lifesaver if it’s the last minute and I haven’t done my waterproofing ahead of time. Even though I mentioned Coghlan’s sealer above being similar, I think the GEAR AID option does perform slightly better.

Considering GEAR AID has 3 of the 5 spots on this list, I guess you really can’t go wrong with any of the options from them!
What Do Tent Seam Sealers Do?
As the name suggests, tent seam sealers are designed to seal the sewn seams on your tent. Whether the seams have already started coming apart or you’re just being proactive and adding an extra layer of protection, a seam sealant will waterproof these areas and make sure nothing can leak inside.
Due to the material that the sealant is made from, it will bond with the fabric of your tent, providing a completely waterproof seal. When the sealant dries, it remains flexible so that it can move and stretch with your tent as you set it up, tear it down, store it, and more.
Since they’re so versatile and easy to apply, seam sealant is also ideal for waterproofing any rips or tears that you’ve recently repaired. A tent patch or repair kit will only do so much, but adding seam sealant will make sure it’s completely fixed and waterproof.
Are Tent Seam Sealers Worth It?
When it comes to your camping gear, taking care of it is the best way to get the most life out of it. Few things are worse during a camping trip than water leaking in through the seams on your tent, and applying seam sealer is a cheap and easy way to protect yourself from getting wet during your next camping trip.
In short, tent seam sealer is absolutely worth it and is something everyone should add to their camping checklist.
That said, applying seam sealant is just one of the three main ways to waterproof your tent, along with applying waterproofing sprays and refreshing the tent’s urethane coating.
