What To Look For In A Tent Seam Sealer

As you can see from the comparison of all of the tent seam sealers in this study, they are all effective on particular types of fabrics and materials. Make sure to get a sealer that is compatible with the fabric of your tent in order for it to be as effective as possible. They should be able to seal nylon, polyester, canvas, silicone-coated textiles and other types of materials, so they should be able to fulfill your needs.

How Thick Is The Sealer?

The thicker the sealer, the more difficult it is to apply, but the coating is typically a little more durable, so the decision is up to you in this situation. Thinner sealers are considerably simpler to apply, but they can drip if you’re working at a height and you’re not paying attention. In any case, you’ll most likely end up having to get used to whatever thickness you wind up picking, so I wouldn’t stress too much about it.

How To Apply The Sealer?

Seam sealer is often applied in one of two ways: by painting, using foam, or spraying the sealant. The majority of the sealers in this study are paint-on sealers, which allow you to be more precise with your application, although it does take some time. The use of spray-on sealers is much more convenient, but you may end up wasting some of the product in the process. Foam applicators are similar to paint brushes, but they’re a bit easier to use because you’re rubbing rather than painting.


Consider how much tent seam sealer you’ll use and get the suitable amount so that you don’t run out in the middle of the project or halfway through. Because they are not particularly costly, it is usually a good idea to get an additional one or two. If you’re setting up a tiny tent, one little tube should enough, but if you’re setting up a large tent, make sure to obtain a bottle that holds at least 4 ounces.

Choosing The Right Tent Seam Sealer

When it comes to choosing a tent seam sealer, there are a number of factors to take into consideration. I understand that choosing one from so many options may be intimidating, especially for newcomers who are unfamiliar with the market. As a result, I prepared this tutorial to assist you.


When looking for a seam sealer, the first thing to consider is the type of material that your tent is constructed from. The majority of synthetic textiles, such as nylon and polyester, may be treated with any of the items mentioned here with no problems. A silicone – coated fabric should be sealed using a silicone – based seam sealer, such as the Gear Aid SilnetSilicone Seam Sealer, if the fabric is composed of silicone. Most likely, you will not need to seal it at all if it is constructed of Cuben Fiber, which is also known as Dyneema in some circles.

This is why thoroughly studying the material from which your tent is constructed is essential before spending your hard-earned money on a tent sealant.

Look over your instruction manual to see if there are any recommendations for you.


The thickness and viscosity of a sealer will differ from one product to the next depending on the manufacturer. Different levels of thickness will each have their own set of advantages and disadvantages, so you should make your decision carefully based on your requirements. Thick sealers are more difficult to apply, but they are more effective in coating seams because of their thickness. The same can be said with thin sealers; they are more convenient to apply, but if they run, you will wind up squandering portion of the product.

It’s important to note that the thickness of a sealer isn’t set in stone. Alternatively, if your sealer is too thick, simply thin it down with mineral spirits and you’ll be ready to go.


Although it may seem self-explanatory, seam sealer should only be used on the seams of a tent – or, in certain situations, on an area where the tent has been damaged – as the name indicates. Using a tent waterproofing spray in conjunction with a tent seam sealer will provide you with a completely waterproof coating for your whole tent. There are a variety of methods for applying seam sealer, however the most of them are personal taste. The most prevalent variety is known as paint-on, and it is exactly what it sounds like: it is painted on.

The Coleman, for example, comes with a foam applicator pad, which makes it much simpler to apply everything to the seams in a uniform and consistent manner.


The size of your tent should be used to determine how much volume you will require. One tube should be more than plenty for sealing all the seams of your little tent if you’re planning on camping in it. Naturally, a larger tent will require a greater quantity of product. Make a note of how many feet of seams the seam sealer you choose will be able to seal, and use that information to calculate how many tubes, cans, or bottles you’ll need for your tent.


Of course, while selecting a certain piece of camping equipment, you should consider the price, just as you would with any other purchase. Sealant is an investment, and although you don’t want to spend too much money on it, you also don’t want to use a low-quality product that will crack and peel once it’s dry. Because internet stores have lower overhead than brick-and-mortar stores, purchasing items online is typically less expensive than purchasing them in person. Just make sure that you always prioritize product quality above pricing in order to get the greatest possible outcomes.

Our Verdict

I hope that this advice has made it simpler for you to make an informed decision about which tent seam sealant is the most appropriate for your needs. All of the alternatives we’ve provided you are of the highest caliber. However, if you want my professional recommendation, I’d have to say that the Seam Grip Seam Sealer from Gear Aid is the best option available. Its adaptability and level of waterproofing are unmatched by any other product on the market, making it an excellent choice for many applications.

In addition, because of the sealer’s flexibility, it will roll with the blows rather than shattering at the first hint of movement or impact.

All of this combines to make it the finest tent seam sealer available on the market today. Just keep in mind that one tube will cover a distance of 12 feet, so if your tent is very large, you may want to get two or three tubes instead. Have a great time camping!

How to Determine if You Need Tent Seam Sealant

  • Before you begin resealing seams, it’s important to evaluate if you actually need to do so. However, if your tent’s fabric has unsealed seams, you should apply a seam sealer
  • However, if your model has taped seams, you may not need to use one if the tent has been in use for less than two years. Check the seams on the rain fly and the floor to see if the seam tape is still shiny, smooth, and flat. If not, replace it with new seam tape. Over time, seam sealing tape may become loose and may need to be reapplied. As previously stated, this is especially true in high-stress regions such as the seam connecting the tent floor to the canopy, on corners, and around any zippers. You’ll need to double-check whether the seam sealing solution you’ve chosen should be placed on the inside or outside of the seam once you’ve verified that your tent requires assistance. It is possible that this is dependent on whether side of the original seam seal tape or DWR seal was applied. Simply squirt some water on the seam to seal it. If the droplets clump together, the seal is on the other side of the container. As long as the droplets do not bead up or roll away, you are most likely on the correct side of the original seal. You can proceed to remove the original seal once you’ve determined which side it’s on, if the sealant in question is a DWR coated goop-type sealer. A toothbrush or other tiny, dense brush will be useful
  • If your tent has taped seams, it is recommended to try to keep the original seam sealing tape in place as much as possible, only applying sealant to replace the seam tape where it may have lifted during the cleaning process. Following the completion of this phase, you may proceed to set up the tent and apply the sealant. Even though the majority of seam sealer products are applied in the same way, there may be subtle changes in their lifetime and drying time, as well as their application technique. When utilizing a product, always double-check the manufacturer’s directions before proceeding.


Here are some frequently asked questions that we receive from our readers:

How Long Does Seam Sealer Take to Dry?

Tent seam sealer takes around 3-4 hours to cure completely, depending on the brand. In addition, keep an eye on the weather. When compared to damp and humid locations, the heat of dry arid Arizona speeds the drying process.

How Waterproof Should a Tent Be?

A “excellent” waterproof tent has a hydrostatic head rating more than 3,000mm. The majority of waterproof rating systems use millimeters as their unit of measurement (mm). In an ideal world, a truly waterproof tent would have a water resistance of between 1000mm and 10,000mm. As you can see, there is a tremendous variety. That is, a 1,000mm waterproof rating can withstand a 1,000mm funnel of straight water before it begins to leak, according to the official definition. An umbrella, for example, is often certified at 400mm in diameter, although it does not typically withstand the same kind of water abrasion that a bathtub floor or the floor of a tent could.

A waterproof jacket, on the other hand, is often 1,500mm or more in length.

Yes, but duct tape is officially “water-resistant” rather than “waterproof,” although there is duct tape specifically engineered for water resistance, such as Gorilla tape.

Duct tape and gorilla tape will both lose their efficacy over time. There is little doubt that it will not be visually appealing, but who cares if you are dry?

Final Seam: Finding the Best Seam Sealer for Tents

Once you’ve settled on a sealant, applied it to your tent, and allowed it to cure completely, you should put the tent through its paces before heading out on your camping trip. The most straightforward method of accomplishing this is to set a sprinkler near the tent to simulate rain. Make an effort to direct the sprinkler so that the waterfalls fall on all four corners of the tent. You’ll want to put the tent through its paces for a long length of time (about 2 to 3 hours) to make sure the seals are completely secure.

Instead, check your tent every hour or two to ensure that it is still leak-free.

Bottom Line: If you are still undecided, I would personally recommend the Gear Aid Seam Grip Seam Sealer, which is available here.

How to Choose the Right Waterproof Sealer

Before you choose a seam sealer, you need first determine whether or not you require one in the first place. There are four scenarios that might apply to you:

  1. It is necessary to use a seam sealer (and maybe some type of waterproof coating) if your tent leaks. If you purchase a brand-new tent that does not have taped seams, you may want to take the precautionary step of sealing your seams. If the seams on your brand-new tent are taped, you probably won’t need to seal your seams at all. For those who have a used tent and the taped seams are starting to come apart, you’ll probably want to invest in a seam sealer.

Consequently, the most pressing question at this time is how to select an excellent tent seam sealer from among the countless options available on the market. As a starting point, you should be aware that there are two different types of seam sealers available: tape and adhesive. Tape binds two surfaces together (the tape and the tent), whereas adhesive creates more of a waterproof seal by filling in pinpoint holes in a surface, such as a window.

Is one of them superior than the other? This is not always the case. Both are effective, but you may prefer one over the other in certain situations. We’ll get to it in a minute or two, though.

Tape Seam Sealer

Manufacturing companies typically tape seams because the tape they use requires a specific method to secure it properly. Not all tents are taped, but the ones that are utilize a high-quality adhesive that will last a long time are the ones that are worth buying. Over time, the tape may begin to break down and flake off, but if you take good care of your tent, this will not happen anytime soon. Tent seam sealant tapes are available for purchase and usage by the customer themselves. If you want a watertight seal, you must be certain that the tools you use are specifically designed for seam sealing.

Great-quality cassettes that are well-known for their effectiveness are recommended in the following section.

Adhesive Tent Seam Seal

Manufacturers seldom, if ever, apply adhesive tent seam sealers in advance of the tent’s arrival. In comparison to tape, this form of tent seam sealer may be a little more difficult to deal with. It is necessary to brush it on all around your tent, and it will take between 2-48 hours to dry. You must be extremely careful not to paint over mesh panels or pockets, and you may even need to use painter’s tape to prevent this from happening. However, when used properly, a high-quality adhesive seam sealer may provide an airtight, watertight seal that is unmatched by tape sealers in terms of performance.

Two Types of Adhesive Sealer

There are two distinct types of adhesive waterproof seam sealers available, each of which is designed for a different type of tent fabric.

  • The first kind is a silicone-based sealer, which is only suited for materials that have been silicone-coated. These coatings are often seen on lightweight tents
  • The second kind is a urethane-based (or water-based) sealer that is used on heavier tents. Polyurethane-coated textiles are the subject of this kind, which is similar to the preceding category. Polyurethane is used to cover the majority of tents. It is critical, however, not to make educated guesses. Because these sealers are not interchangeable, you must be aware of the type of coating your tent is constructed out of.

The Time it Takes to Dry

As previously said, it can take anything from 2-48 hours for an adhesive sealer to completely dry, or cure, as it is frequently referred as. You should think about whether or not you want to apply a tent seam sealer. Are you employing it as a prophylactic precaution before going on your camping vacation with your family? If this is the case, you may almost certainly utilize one that takes any amount of time because you can prepare ahead of time. Are you using it to fix a leak in the middle of your camping vacation since it happened unexpectedly?

Keep in mind that when using fast-drying adhesives, you will almost certainly have to sacrifice some quality in the process.

The Outside Temperature

If you’re prepping your tent in advance of your trip, you’ll have a little more leeway in deciding what temps you want to seal your seams in. If a sealer requires a specified temperature to cure, this is a greater worry while you’re out camping and need a speedy fix. Using a sealer that requires room temperature to cure will not be appropriate if you are camping in snowy conditions. The temperature at which you’ll be working with your sealer might make the difference between employing a sealing tape and an adhesive for your project.


Let the cost of sealers influence your decision-making process just somewhat. You may be tempted to get something inexpensive in order to save money, or you may decide to purchase the most costly sealer because you believe it is the finest. However, neither of these suggestions is a good one. This is due to the fact that the cost of sealers vary depending on factors more than just quality. It might be due to the size, color, material used, brand name, and a variety of other factors. When it comes to budgeting, we realize that you want to keep costs as low as possible.

We set out to locate the finest seam sealers available on the market based on the criteria listed above.

We were able to come up with five that were suitable. With regard to overall performance, we’ve listed the top five options in the following area, along with the advantages and disadvantages of each.

The Best Waterproof Sealant for Tent Seam Sealing Reviewed

Gear Aid is a corporation that specializes in the production of “gear aid” for use in outdoor environments. As a result, they are much more than just a firm that manufactures sealers among hundreds of other products. This implies that they understand what it takes to manufacture a great sealer since they specialize in it, and the quality of their goods reflects this knowledge. I’m quite pleased with this silicone seam sealer. It is true that it is difficult to deal with, but a small amount (only a few drops) of mineral spirits may make it a bit simpler to distribute.

tube is enough to cover a tiny two-person tent.

This sealer cures about 6 to 8 hours if it is applied in the appropriate manner.

  • Made in the United States
  • Includes a brush. After curing, it becomes flexible, allowing for high-performance applications. Dries to a transparent color
  • It will not heal properly if it is too chilly outside. Moreover, it is incredibly thick and difficult to distribute

Summary: If you are not going to be distributing in a chilly area, this is a fantastic sealer to use.

Coghlan’s Seam Seal

Coghlan’s tent seam sealer is a low-cost seam sealer that does a respectable job overall. It’s a water-based sealer for polyurethane-coated fabrics that’s simple to use and to clean up after. Because of the consistency of the product and the brush that comes with it, you should be able to cover at least a small, two-person tent effectively without wasting any of it. One particularly advantageous characteristic of this product is that, unlike the Gear Aid Sealer, it may be used in cold weather without compromising performance.

Bottom Line: If you’re looking for a low-cost sealer that you can use for casual camping, this is a fine selection.

Coleman Seam Tape

Because Coleman is one of the most well-known and established outdoor goods firms in the country, we’ve included this cassette in our collection. This Coleman tape is a fantastic product that adheres to most synthetic textiles with an acceptable amount of sticky adhesion. Despite the fact that we don’t advocate using it for your entire tent, it is excellent for rapid and/or emergency repairs. It may be utilized in almost every scenario, with the exception of rain. The tape is 3 in. x 18.5 in.

It is most effective on synthetic textiles.

When working with heavier fabrics, such as those with at least 70 deniers or more, we recommend that you use seam sealing tape.

  • Excellent for last-minute repairs
  • It’s a transparent color. It is simple to use

Bottom Line: While we would not recommend using this to pre-treat an open seam, it is an excellent alternative for rapid patches, emergency repairs, and strengthening.

Gear Aid Seam Grip FC

Gear Aid seam sealant (urethane-based) is yet another product we’ve included in this kit. This waterproof seam sealer, like the silicone-based Gear Aid waterproof seam sealer, is of exceptional quality and is suited for the majority of tents (since most tents are coated with polyurethane).

These are the two reasons why we have ranked it as the best sealer out of the five on our shortlist. When you apply this sealer, you will have a long-lasting seal. If you take good care of your seam, you’ll have a beautiful, water-resistant seam that will last a long time.

  • A pair of mending and sealing brushes are included in the package. It produces a permanent seal. It has self-leveling properties, allowing for even application.
  • It takes a long time to dry (it has to be dried overnight). Because it must be stored in a freezer, it is not ideal for use in emergency situations when camping.

Overall, this seam sealer performs the best of the five tested products. You will be pleased you took the effort to pre-seal your seams before going camping, even though the process is a little lengthy and the need to put it in the freezer is inconvenient.

Gear Aid Tenacious Seam Sealant Tape

Gear Aid has provided me with a third product since their products are fantastic. This is one of the strongest sealing tapes on the market, and it is available in a variety of colors as well. The nylon tape in the colors black, yellow, and red is used. The ripstop tape in gray and green (sage) is used for this project. You also have transparent tape, which is usually your best pick for tents unless you’re only interested in colorful tape, in which case colored tape is your best bet. It is available in two sizes: a 3′′ × 20′′ strip and a 1.5′′ x 60′′ roll.

The application of this tape is uncomplicated.

One thing we don’t like about the product is that the business claims that you may wash your cloth within 24 hours and that the tape will remain in place, but this isn’t exactly accurate.

Using it in a tent, on the other hand, will most certainly eliminate the need for this concern altogether.

  • It is available in a variety of hues. It has an extremely strong adhesive on the back
  • It may be used on fabrics such as GORE-TEX.
  • The clear color is only available in rolls
  • No other options are available. Despite the fact that it purports to be washable, it falls off after the first wash.

Overall, this is a fantastic tent sealer that has excellent hold and is very easy to work with. You won’t have to be concerned about it pulling off until it has dried completely.
