How To Seal Seams On A Tent

How to Waterproof and Seam Seal a Tent

The feeling of being snug inside your tent, listening to the crickets and cicadas sing you to sleep, is second to none—that is, until you wake up soaking wet from a leak that had gone undetected for several hours. It’s critical to waterproof and seam seal your tent to ensure that you don’t wake up in a puddle or that your camping gear isn’t ruined on your next camping excursions. When tenting in the great outdoors, there are four primary categories of challenges that tent dwellers are likely to encounter:

  • There is water leaking through the seams, which has to be fixed
  • Infiltration of water via the rainfly, which requires a water resistant coating
  • Wetness seeping into tent floor, indicating that the polyurethane covering is beginning to peel away
  • Condensation accumulates as you sleep, necessitating the need to unzip the zipper to enable more air to flow through

It doesn’t matter what kind of tent you have or what kind of leak-proofing you require; Stuff AID will assist you in keeping your gear watertight and you dry. Whether you’re camping in Yosemite or pitching up a tent in your own garden, you should prevent leaks from occurring in the first instance. Find out how to make quick and easy repairs to your tents and tarps that will last for years, so you can confidently return to sleeping quietly in the great outdoors. A puddle is hardly a place you’d like to sleep—so if you discover a bothersome loose or damaged seam in your tent, fix it as soon as you possibly can.

The most important step in completing this do-it-yourself job successfully is to choose the proper sealant for your type of fabric as well as the location and size of the treatment area.

  • A bowl of cold water
  • A sponge that is not rough
  • Revivex Pro Cleaner or light liquid soap
  • Seam Grip WP, Seam Grip FC, or Seam Grip SILWaterproof Sealant
  • Revivex Pro Cleaner or mild liquid soap

Time Estimated: Approximately 30 minutes 20 minutes are allotted for application. Duration of cure: 2–12 hours, depending on the sealant used. Steps:

  1. Set up your tent in the garage or backyard if you have one. The rainfly should be laid down flat with the underside facing up while it is being sealed. Combine 1 fluid ounce of Revivex Pro Cleaner in a basin of cold water
  2. Set aside. Preparation: Wipe down the seams you intend to seal with a moist cloth or sponge saturated with your solution
  3. Then, using the provided brush, apply a thin coating to the exterior seams of the house using the appropriate Seam Gripseam sealer. In order to seal a silnylon tent or tarp (see the chart below for reference), use a silicone-based sealer. Maintain level and allow to cure according to the directions on the container (about 2-8 hours)

Pro Tip: After the Seam Grip WP has been cured, sprinkle baby powder over the seams to keep them from sticking together. Even while a rainfly is intended to provide an additional layer of protection between your sleeping bag and Mother Nature, they can become prone to wear and tear over time as well. Fortunately, with a combination of Seam Grip and Revivex, sealing nylon from top to bottom is a straightforward process. You may now sleep easily in your entirely secure and dry tent once you’ve finished sealing any loose seams using Revivex Instant, a spray-on water repellent, and completing the reproofing procedure.

  • A bowl of cold water
  • A sponge that is not rough
  • Revivex Pro Cleaner or mild liquid soap
  • Revivex Instant Water Repellent
  • Revivex Pro Cleaner or light liquid soap

10-15 minutes is the time estimate. Steps:

  1. Lay your rainfly flat on the ground with the top side facing up in a well-ventilated place. Pour 0.5 fl oz of Pro Cleaner into a basin of cold water and stir well. Wet your sponge with the solution and use it to clean the rainfly from top to bottom. After the cloth has been thoroughly cleaned, spray it with Revex Instant Water Repellent. Make certain that the cloth is totally dry before storing it to avoid the formation of mold or mildew.

Water does not necessarily enter your tent at the top; it can also enter through the bottom of your tent and seep up through the floor. It’s a circumstance that will undoubtedly cause you to awaken from your lovely slumber fast (and painfully). Use Seam Grip TF to repair the polyurethane (PU) protective coating on the bottom of your tent to prevent water from seeping up through the bottom of your tent.

  • Isopropyl alcohol, Revivex Pro Cleaner or mild liquid detergent, Seam Grip TF Tent Fabric Sealant, and a dry brush are all recommended.

Time Estimated: Approximately 30 minutes 15 to 30 minutes for application Cure time is 8-12 hours. Steps:

  1. Using a dry brush and isopropyl alcohol, remove the old, damaged PU coating from the surface. Alternatively, you may soak the tent in a solution of water, Revivex Pro Cleaner or mild detergent, and an isopropyl alcohol combination to remove the previous PU covering. Following cleaning and drying the area, shake Seam Grip TF and push the sponge down while pinching to saturate the applicator with product. Apply a thin, uniform coat of paint to the fabric of the tent’s inside. It is recommended to use a single coat. After four hours, check the tent for dryness and wait 24 hours before storing it away.

When the factory PU coating starts to peel and flake off, it’s time to replace it, according to our experts.

It may also grow sticky or emit a terrible stench as time passes.

Tent Seam Sealers 101

It is a type of application (usually tape or glue) that is used to seal the leaky seams of a tent to prevent water from leaking in. When the tent fabric is sewn together along the wall and the floor, this is known as a tent seam. These seams are infamous for leaking when there is a lot of rain, dew, or water runoff, among other things. In a tent, water will leak in via stitching that has either 1) not been properly sealed in the first place or 2) has become worn out over time. During the production process, the majority of firms waterproof the seams.

Step 1: Make Sure You Need Seam Sealant

If there is no tape on the seams, or if the tape is coming off, you should consider sealing the seams with an additional layer of sealant to ensure that they are completely watertight. TAPING THE SEAMS:Taping the seams is a typical practice in the construction of most retail tents. It is a thin, flexible tape that acts as a physical barrier between the user and the rain. Because most tents have their seams taped during the production process, you shouldn’t have to worry about tape sealing them immediately out of the box when they arrive.

Tents that have been correctly taped will have a layer of transparent tape incorporated into all of the seams, including those around the walls as well as along the floor of the tent.

B) SEAM Sealer: A waterproof substance, such as glue or goo, that permeates into the tent fabric and repels water is used as a seam sealant.

It is physically brushed onto a seam in order to guarantee that it penetrates the holes created by the sewing process.

Step 2: Select Sealant Based on Tent Fabric

Different types of seam sealants are required for different types of tent materials and textiles. As a result, you must identify the sort of tent cloth that you have. If you are unsure of the material of your tent or tarp, you can always look it up on the manufacturer’s website or get in touch with them. A) SILICONE COATED Textiles: Silicone coated fabrics are frequently used in ultralight tents and tarps. As previously stated, silicone-based sealants are required to be used on these textiles since silicone is the only substance that will cling to the silicone in these fabrics.

To make your own DIY silicone sealer, use one part 100 percent pure silicone with one part mineral spirits in a one to one ratio.

B) POLYURETHANE COATED FABRICS: Polyurethane coated tent fabrics, like silicone tents, can only be treated with a urethane-based sealer, similar to the silicone tents. A silicone sealant will not work in this situation. The best urethane sealants are as follows:

  • Gear Aid Seam Grip FC (Flexible Gear Aid Seam Grip FC) (formerly Seam Sure). Seam Grip FC is a water-based sealant that dries in as little as two hours and is ideal for use in tight spaces. Gear Aid Seam Grip FC is suggested above Gear Aid Seam Grip WP unless you want a thick coating of waterproofing. This is because it is easier to work with than Seam Grip WP. Gear Aid Seam Grip WP is a water-based product that penetrates into the fabric of the tent and is easy to clean (formerly Seam Grip). Unlike other urethanes, Seam Grip WP is a thermoset compound that goes on thicker and requires longer to cure. It’s so thick that you can use WP as a glue to hold things together. Because it is so thick, Seam Grip WP necessitates the application of more elbow grease in order to fully penetrate the fabric.

ColemanandCoghlans also manufactures water-based seam sealers that are quick to dry and come with applicator pads to make application a simple task. Simply tip the bottle and use the applicator included inside the bottle to brush on the sealer. DYNEEMA (CUBEN FIBER) FABRIC (COLOR: C): It is not necessary to seam seal Dyneema tents in most situations. Alternatively, if you want that extra layer of protection, you may use the lightweight Gear Aid Seam Grip FC or a comparable water-based sealer.

Step 3: Apply the Seam Sealer

A few simple items, an hour of your time, and a few days of drying time are all that are required to repair a leaky tent. PREP: Look for a day with low humidity and temperatures ranging from 50 to 70 degrees (F), so that it can dry quickly. Make certain that you cover every seam and that you seal the seams from both the inside and the exterior. The tent must be set up in the manner in which it would typically be used for this purpose. MATERIALS: Before you begin, you’ll need to gather the materials listed below.

  • Cloth: for cleaning the seams that are already there
  • Cleaning existing seams with rubbing alcohol is recommended. Make sure you use the suitable seam sealer for your tent fabric. Seam Sealer: For applying the sealant, a brush (about an inch broad) is recommended. Some sealants are packaged with a brush
  • However, this is not always the case.

HOW TO APPLY: 1. Set up a tent in your yard. In order for you to see all of the seams on your tent, set it up outside in a dry, sunny area or in a brilliantly lighted room. Put the fly on from the inside out so that the seams are visible. 2. Remove any sealant tape that has been damaged. Check for any loose or broken tape that may have come loose during the process. Try to keep the pieces that haven’t been harmed intact while gently removing those components. 3. Seams that are free of debris.

  1. Using a damp cloth and rubbing alcohol, clean it well.
  2. 4.
  3. Utilizing your brush, dip it into the sealant mixture and apply it to the inside seams of your home or business.
  4. Excess should be wiped away as needed.
  5. Some individuals choose to cover zippers and other sensitive places using painter’s tape rather than using a glue stick.
  6. Seal the outside seams with a sealant.
  7. 6.
  8. Allow for 12 to 24 hours of air drying time for the tent.
  9. 7.
  10. Spray your tent with a garden hose and inspect it for leaks to ensure that your task is done correctly.

  • Prevention of Leaks: If rain does not bead up on the walls of your tent, you should consider treating it with a fresh coat of long-lasting, water repellent (DWR). This coating is excellent for treating the tent’s exterior as well as the rainfly’s exterior. As a waxy coating, it prevents water from being absorbed through the walls of the building. Preventing Seaping Using the Following Methods: Make use of a groundsheet (tent footprint) underneath your tent to prevent it from absorbing water runoff and moisture from the soil. In order to avoid holes, choose your tent site wisely and clear away any rocks or sticks to avoid coming into contact with any potentially abrasive surfaces. In the case of small holes, tenacious tape can be used to repair them. It is a super strong tape that is designed to be lightweight, flexible, and rugged so that it can be used outdoors.

Tents 101: Seam Taping vs. Seam Sealing

It’s never pleasure dealing with leaking seams, especially when it’s raining in the middle of the afternoon. However, the seams of a tent are also its most vulnerable area when it comes to stray and persistent water. Manufacturers of tents have three alternatives for preventing infiltration: using seam tape, using seam sealing, or building a robust seam construction from the ground up. Because you’re reading this, it’s likely that you’re inquisitive about the differences between these two options.

  1. Let’s get started.
  2. Seam tape does exactly what it says on the package.
  3. The tape has the effect of a dam.
  4. Tent manufactures are normally certified to use seam tape in their products.
  5. When used in tents, the approach is same, but the manner in which it is implemented differs.
  6. What exactly is seam sealing?
  7. The tents, such as some MSR tents, are seam sealed from the factory, whereas others are not.

If the remainder of your tent is still in excellent condition, seam sealing is a fantastic option to keep it in good condition rather than having to purchase a new tent.

When the sealant is put on, it seeps into the stitching holes and forms a watertight barrier around the area.

Let’s start with a question: Have you ever had a tent with flaking seams that you didn’t like?

Some applications benefit greatly from the use of seam tape, whilst others do not.

This is due to the fact that the tape sticks to certain textiles extremely effectively, providing long-term protection.

When used on thinner tent materials, the tape simply fades more quickly.

Depending on how well you take care of your tent, this might take several years, or it could happen rather rapidly if you don’t.

Furthermore, once the tape is removed, your seams are rendered unprotected.

In the presence of moisture, heat, and humidity for an extended period of time, seam tape can begin to break down and flake away from lightweight tent fabrics.

However, as tent materials have become lighter in weight, we have discovered that even the finest seam tape does not match our requirements for long-term performance.

The introduction of our new Xtreme Shield waterproof covering, which includes precision-stitched, factory-sealed seams, is something we’re delighted to announce for 2019.

Is it necessary to seam seal my tent?

In addition to providing a waterproof barrier, seam sealing will also help to increase the life of your tent.

As in the case of MSR’s Hubbaseries, if your seams are sewn and factory sealed, but wear has exposed regions to leaks over time, seam sealing is significantly easier to do.

Apply the sealer on the fabric’s underside/inside (or glossy side) using a sponge or a brush.

We’re gearheads, and we’ve put the various seam sealants on the market to the test.

ChooseSeam Grip +WP if you want the most explosive one.

It does need a small amount of work and a lengthier drying time than other options.

Sometimes simply caulking the areas where you’ve detected drips is enough to prevent further damage.

However, a little tender loving care may go a long way toward preserving its quality. Now, enough with the technical jargon. We believe that this technology can be used in tents and should be used in tents! Posts related to this one:

How to Seam Seal a Tent

Whatever the weather conditions are—dew, rain, or a sudden downpour—water has the ability to seep into any shelter through needle holes in the seams or an unintentional pinhole or rip. You may need to treat your shelter at some point, whether it is seam-sealed and completely waterproof, factory-taped, or otherwise untreated. This will keep the elements at bay while also maintaining the structural integrity of your shelter. Fortunately, the seam-sealing procedure is quick and rather straightforward.

Always adhere to the manufacturer’s recommendations as well as the manufacturer’s guidelines for your seam sealant.

The following McNett items are highly recommended by several tent companies:

  • Designed for use on shelters made of nylon or other synthetic materials, as well as natural textiles, waterproof laminates (such as leather), and vinyl, SeamGrip is a great addition to your shelter arsenal. It can also be used to permanently fix pinholes and tiny rips
  • However, this is not recommended.
  • SilNet is intended for use on shelters constructed of silicone-coated textiles, such as silnylon. It may also be used for simple on-the-job repairs in the field.

Application of the two is nearly same in terms of procedure (follow the directions for your sealant).

Preparation

The first step in seam sealing is to start with a clean, dry tent. Tent floor, fly, and bottom of tent body seams and connection points are the most vulnerable to water intrusion, therefore pay close attention to these areas and the tent’s attachment points. There is no need to seam seal any of the mesh. Because extended exposure to seam sealant without appropriate ventilation can be hazardous to your health, you’ll want to complete this task outside if possible. Also, choose a warm, dry day to complete the project because it will take some time for the sealant to properly cure.

  1. Clean your tent and rain fly as thoroughly as possible. Using water and, if required, a very mild, non-detergent soap, thoroughly clean the tent (check with your manufacturer for their recommendation). It is not recommended to use detergents, bleach, dishwashing liquid, stain removers, or strong soaps, since they can eat through the fabric of your tent and any coatings it may have. Rinse well. Allow for complete drying of your tent, which should be erected or strung on a line in a shaded location. Never dry your tent using a machine. Once your tent is clean, dry, and tautly erected, you may go on to the next step: seam sealing.

The Seam Sealing Process

When applying sealant to the tent and fly, make careful to pull them taut as much as possible. Now comes the step when you have to put the sealant on the joints. You should seal all of the seams of your shelter at once if you’re sealing your shelter for the first time and not in reaction to a specific leak. This will help to guarantee that your tent doesn’t break while you’re in the middle of a rainstorm days away from a repair. Pay close attention to the tent’s most exposed seams, which include the tent floor, fly, and bottom of the tent body, as well as the webbing connection points, which are the most probable places for water to enter.

The maker of your shelter may advise you on which seams to seal and which ones to leave open.

  1. Apply painter’s masking tape to the inner walls 1/4 of an inch from both sides of the seam on both sides of the wall. This will make it easier to apply the sealant and will prevent the sealant from spreading out too much during the application process. It will also offer your job a more professional appearance
  2. Sealant should be applied to the inside wall seams of your tent, with the lowest half receiving the most attention. Continue around the perimeter, leaving a thin coating of sealant that extends roughly 1/4 of an inch over the edges of the seams. Pay close attention to making sure that all of the needle holes are filled in. Mesh portions do not require sealant, however it will add added strength to the stitching by keeping it together more tenaciously. Take care not to get sealant in the zippers. Make use of the same amount and breadth of sealant for sealing any seams on the tent floor. Make sure that all of the tent’s seams are taut before closing the tent’s opening and applying another coat to the exterior of the tent. Many tents are delivered with seams that have been factory taped. The exterior seams of these tents may be sealed in order to provide optimum waterproofing. It is possible to use sealant like glue to close a seam and then reapply the tape in the event that it begins to peel. Allow the tent to air dry
  3. When it comes to one-piece tents, the sealing is complete. When using a tent with a rain fly, it is best to place the rain fly on upside down so that the interior seams are visible. Continue using the same procedure as described before in order to seal the fly’s seams.

Afterward

  1. You may seal both sides of the rain fly here if you want to provide even more protection. Make sure that the tent is left tight to dry and that the rain flap is securely fastened to the tent. Allow for complete drying of both parts for 12 to 24 hours, or overnight if the weather permits
  2. Applying seam sealant to the other side of your rain fly and tent bottom will provide an additional layer of protection. After all of the seams have dried, it’s time to get creative. Establish a routine for setting up the tent, then put on the sprinklers for an hour or so. Climb inside and take in the beauty of your creation. Examine the sealant for any leaks or cracks in the sealant. Testing the seams thoroughly now will guarantee that there are no surprises out on the trail later on in the trip. Allow your tent to dry completely before repeating the seam sealing technique on any troublesome places if necessary. Once your tent has been completely cured and dried, keep it in a loose manner away from direct sunlight and outside of its stuff pouch. Your shelter is now complete and ready to be used

Questions and Considerations

Pay great attention to the tie-down points in the corners, as these are particularly vulnerable. Is it true that my tent’s seams are factory taped and hence seam sealed? No. Tents that are more recent in design frequently have factory-taped seams. This signifies that a waterproof material has been doubly sewn between the tent’s seams to keep the elements out. However, while a factory-taped seam is normally fairly water-resistant, and it should stand up well in compared to not sealing the seam at all, it is not the same as totally waterproof seam sealing.

  1. I’ve just spent a significant amount of money.
  2. Some tent manufacturers seal the seams of their products.
  3. You may find that seam sealing your shelter yourself is far less expensive.
  4. Shelters constructed with silicone-treated nylon are not factory-taped, as seam tape does not adhere to the material when it is wet.

Is it necessary for me to seam seal my new tent? First and foremost, always check with the manufacturer of your tent, since most have their own recommendations for how and where to apply sealant based on the materials used and the form of the shelter.

  • If your tent’s seams are not sealed or factory-taped, you will need to seal them yourself after purchasing it. Make sure to start on a warm, dry day before heading out on the trails. If your tent’s seams have been factory-taped, there is no need to seal it. Even though your tent should be very water-resistant, you may wish to check its waterproofness under a sprinkler before venturing into the bush. If your tent will be used frequently, especially in damp weather, consider sealing the seams. An additional coat of sealant will provide your shelter with additional protection as well as optimal waterproofing
  • If your tent is already seam-sealed, there is no need to seal the seams immediately after purchase. However, you may wish to test its waterproofing under a sprinkler to make sure it is enough. Even with seam sealing, frequent inspections and maintenance are still necessary, especially when the system is subjected to a lot of abuse.

There are several different seam sealant products available on the market. Is it okay to apply any kind of sealer on my tent? No. Various sealants are developed for the treatment of specific textiles. Check to see what kind of materials were used to construct your tent (nylon versus silnylon, for example), as well as what the manufacturer recommends. The seam sealer you pick should be suitable for the fabric of your tent, and it should be easy to apply. When should I seam seal or spot treat my tent and how often should I do so?

  1. If you are a backpacker or camper who uses your equipment frequently, you may wish to apply a coating twice a year to protect it.
  2. Apply another layer of sealant if any of the sealant is missing, leaking, or fractured in parts.
  3. What should I do in this situation?
  4. The floor was seam-sealed by myself.
  5. The majority of the time, it is suggested.
  6. In order to prevent water from funneling below the tent, make sure the ground fabric is smaller all around than the tent and does not protrude from underneath.
  7. Keep in mind that the manufacturer’s cleaning, maintenance, and repair instructions should always be followed.

Seam-sealing

Tents made with silicone-coated nylon (silnylon) cannot be machine seam-taped since silicone is an inorganic compound that does not accept polyurethane (PU) seam tape. Instead, silicone-coated nylon tents must be hand-painted. Seam sealing prevents water from entering the tent through the seam holes that are generated during the sewing process. The good news is that the silicone is quite long-lasting, so you will only have to seal your tent once throughout its lifetime. We do not include the expense of this process in our standard price, however we do sell seam-sealing kits for $6-8.

  1. Continue reading for a video on “How to Seam-Seal a Bag.” Permatex Flowable Silicone Windshield and Glass Sealer, which is a commercially available premixed solution that performs rather well, is a good example of this.
  2. Additionally, we provide a seam-sealing service for $35.
  3. It’s less difficult than it appears to be to seam seal your own tent!
  4. Depending on the outdoor temperature and humidity, the seam sealer will dry in 3-4 hours.

After the sealant has dried, you may “check your work” by spraying the sealed shelter with a hose and checking the seams to see whether any water has gotten in through them.

Seam Sealing (Guide) Any Tent or Tarp

It may be necessary to seam seal your tent or tarp in certain situations. Usually after using your shelter for a long length of time (dozens of nights) or if you intend on camping in a particularly damp environment, it is necessary to replace it. In most cases, seam sealer is required where the needle punctured the cloth during the manufacturing process. The sewing machine made scores of little holes in the cloth as it worked its way through it. As the material ages, tension in the material causes those microscopic holes to grow a little bit wider.

Even though this is true for practically all tents, we’ve seen that almost no one takes the time to educate their consumers on this critical step.

Learn Your Tent Fly Fabric

Remember to check with the manufacturer of your tent to find out what kind of sealing agent they recommend using. This is really crucial! Luxe Hiking Gear tents, for example, are made of a fabric that necessitates the use of a silicone-based sealant (approved for PU coated fabrics). In our store, we provide silicone-based seam sealants.

Preparing the Fabric for Sealer

It is critical that you thoroughly clean the tent fabric in the places where you will be sealing it. Set up your tent outside, at a location where you will be able to leave it for an extended amount of time and where the weather prediction is favorable. To ensure a lovely smooth seal, the tent should be taught and wrinkle-free when it is assembled. When it comes to washing the cloth, we like to use isopropyl rubbing alcohol. This substance is easily accessible and quickly evaporates. You may get some from any drugstore.

Don’t Make a Mess

It may be quite simple to get seam sealer on the tent fabric in places where you don’t want for it to be. Applying masking tape beforehand and removing the tape after 30 minutes of drying time are some suggestions for avoiding this situation. Alternatively, you may pre-cut a narrow rectangular stencil from thick paper or card that you already have and just move your stencil about the room while painting strips of seam as you go. Keep the amount of sealer you use to a minimum; you just need enough to fill the stitching holes.

Seam Sealing Your Tent

You are now prepared to apply seam sealant to the seams of your tent. Apply the sealer with a little brush to ensure that it reaches all of the small thread holes. Most of the time, you will want to apply sealant on the outer tent rain fly where it has been stitched. Pay particular attention to the peak of the tent and the regions where the guyline loops pull; because the fabric is under stress in these locations, these are the areas that should receive the most attention if you just have a little amount of seam sealer.

The only part of the tent that requires seam sealer is the exterior of the tent. Seam sealing bathtubs and inner tent floors, when the fabric is near to the ground, is something some people do. This will help to keep your region dry during strong rainstorms and thunderstorms.

After the Seams are Sealed

Leave your tent up for 12 to 24 hours, or until the next day, depending on the weather. Examine and visually examine the region to ensure that you did not overlook any potential problems. In some instances, it may be required to submit a new application. Even after it has dried, seam sealant remains tacky (sticky) to the touch until it is removed. Baby powder or cornstarch can be used afterwards to prevent the sticky sensation, but bear in mind that it will leave a delicate white look on all of your seams.

There’s a good chance that you overapplied.

How to Seam Seal a Tent or Tarp

August 24, 2021 Frequently Asked Questions Seam Sealing a Tent or Tarp When you buy a tent or tarp made with silnylon, it’s best to seal the seams usingGear Aid Silnet Silicone Seam Sealerin order to make them waterproof in the rain. While many manufacturers offer this as an add-on service, but you can also do it yourself. Tents that are waterproofed with polyurethane or polyethylene (abbreviated as SilPU, PU, or SilPE) are usually factory seam-taped and are often sold that way out of the box.

You need:

  • A brush that you don’t mind tossing away when you’ve finished with it
  • A tin can or other container to mix things up in
  • A little piece of card, or a very steady hand are all you’ll need. Cloth that has been dampened
  • Gear Aid Silnet Silicone Seam Sealer, which is sticky and dirty stuff
  • Gear Aid Silnet Silicone Seam Sealer (which is sticky and messy stuff)
  • Thinner for paint

Start by combining 3 parts paint thinner to 1 part Silnet in a tin until you get a workable viscous paste that can be applied easily with a brush to the seams. The main objective is to get it to soak into the stitching so that water may seep in via the openings. If you apply the Silnet without first thinning it, it will cure too thick and will flake off, giving the surface a cluttered appearance. If you dilute Silnet with paint thinner as mentioned above, one 1.5 oz container of Silnet will typically be plenty for a 1-person tent in most cases.

  • Usually, one coat is sufficient.
  • Pitch the shelter in fine weather or in the garage: anywhere where it will be able to dry for the better part of the day.
  • If the item has an odd form that makes it hard to seal all of the seams at the same time, seal them one at a time on a subsequent day and repeat the process.
  • A little goes a long way in this case.
  • After drying, the thinned mixture will soak in and take on a tidy appearance.
  • We may (but not always) get a small portion of any sales made using the links provided above.

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 far more convenient, but you may wind up squandering 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.

Volume

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.
