Things to Consider Before Buying the Tent Seam Sealers

Now that you’ve read the detailed reviews of the best tent seam sealers, the next step is to identify the most critical factors to help you get the best product for your camping adventures.

Here are some of the essential factors to make sure your money doesn’t go to waste.


The tent seam sealer may be suitable for a particular fabric but not for the other. That is why you must find out the fabric coating of your tent before buying the sealer.

  • Dyneema/Cuben Fiber: These fabrics don’t require you to use a seam sealer.
  • Silpoly Coated Fabric: This fabric has a urethane coating on one side and silicone on the other. You should know which side is silicone before applying the sealant.
  • Silicone Coated Fabric: Since this fabric is coated with silicon, you will only need a silicone-based seam sealer.
  • Polyurethane Coated Fabric: You will need to buy a urethane seam sealer for this type of fabric.


The second thing to consider when buying a tent seam sealer is the quantity of sealant you need. A small tube or bottle would be sufficient for a two-person tent. For a larger tent, you will probably need multiple bottles. However, you will be able to save money if you buy a bigger bottle.

Moreover, you will need to buy the sealant in large quantities if you regularly go camping.


Tent seam sealers come with varying thicknesses, so you’ll be able to find both thin and thick tent sealants in the market. However, both have their pros and cons, which is why you’ll need to carefully consider the one you want to get for yourself.

  • Thick Tent Seam Sealer

A thick seam sealer is helpful if you want to attach a specific part of the tent or fabric. This will prevent you from wasting the seam as the sealant doesn’t run along with the material. Most silicone-coated fabric tents are thick, but you can add mineral spirits to make them thinner.

  • Thin Tent Seam Sealer

Thin seam sealers are primarily used among campers. That’s because they’re easy to apply and also flexible since they run along with the fabric.


When buying tent seam sealers, you will find different options of applications. These include paint-on, spray-on, nozzle, and built-in applicators. Here’s a quick rundown of how each applicator is used:

  • Paint-on: You can find two types of this applicator. One is with a brush at the end, while the other is where you paint the tent using a paintbrush.
  • Spray-on: As the name suggests, you can use this to spray the sealer on the seams directly. This is by far the most convenient form of application.
  • Nozzle: Most of the time, the tube or bottle of the seam sealer comes with a nozzle. You can directly apply the sealant from the bottle onto the fabric.
  • Built-in Applicator: Another convenient form of applying sealer is via a built-in applicator available as both brush and foam.

Why Do You Need to Seal Tent Seams?

Sealing the tent seams can offer you more advantages than you can think of. Here’s how the seam sealers prove to be helpful to you while camping.


Tents seem to wear out and lose their original quality over time. Thus, seam sealers help maintain and repair the tents to avoid any problem when camping in the wilderness.


The primary purpose of sealers is to protect the tent seams. Nowadays, several tents have sealed edges, while others come as simply stitched. Stitched tents are usually watertight, but using sealers will add more waterproofing and strength to protect against any chance of leakage.

Frequently Asked Questions (FAQs)

Is duct tape effective in sealing the tent?

Duct tapes are water-resistant but not waterproof. However, Gorilla Tape can offer more water resistance than standard tapes. Still, they tend to lose their effectiveness over time.

How long does it take for a Seam Sealer to dry?

Typically, it takes about three to four hours for seam sealers to dry. This time can vary as per the weather conditions. In areas like Arizona, the drying process is much faster compared to more humid and moist areas.

What waterproof level do you need to have in your camping tent?

A waterproof rating higher than 3,000 mm hydrostatic head is considered good, although the ideal range is from 1,000mm to 10,000 mm. This means a tent with a 1,000 mm rating can only sustain a water funnel of 1,000mm before it begins to leak.

Final Thoughts

A tent seam sealer is a necessity for an exciting and comfortable experience while traveling outdoors. The last thing you need is for unexpected weather conditions to ruin your trip. Therefore, you must be prepared in advance to tackle such situations.

If you have already found your suitable sealer, all you need is apply it to your tent and wait for it to dry. After drying, you should first test whether the tent effectively protects from leaks or not. You can do this by sprinkling some water on the sides to see if the seals are properly secured.

After that, you’re set to go and experience new adventures where rain or other extreme weather conditions can’t interrupt your trip!
