Scotchgard Heavy Duty Water Shield

However, while all of the sprays discussed here are wonderful, they do have one significant flaw: almost all of them are designed just for the waterproofing of nylon and polyester tents, and they are unable to provide any protection for canvas tents.

Choosing A Tent Waterproofing Spray: A Buying Guide

When it comes to selecting the best waterproofing spray, there are three crucial considerations to keep in mind:

  1. Aerosols vs. spray bottles
  2. Silicone vs. non-silicone sprays
  3. The type of tent fabric it’s intended for
  4. And other considerations.

Aerosols vs. spray bottles; silicone vs. non-silicone sprays; the type of tent fabric it’s intended for; and other considerations are discussed.

Aerosol Vs Spray Bottles

The first thing you must determine is whether or not to utilize aerosols or spray bottles – both have advantages and disadvantages that must be considered.

Aerosol Bottles Spray Bottles
Application Click and spray Pull the trigger and spray
Pros Easy to use, penetrate the fabric better Better control using the spray
Cons Bad for the environment, must use several cans Might end up spraying your tent unevenly

Aerosol sprays are simple to use — all you have to do is press a button and spray away. They also permeate the cloth a little better than the previous version. On the negative, they are not very kind to the environment, and you may find yourself applying far more spray than you intended. Spray bottles function similarly to spritzers in that you must manually pull the trigger before the spray will come out. On the bright side, you have considerably greater control over the amount of spray you use than before.

Silicone Vs Non-Silicone Based Sprays

I’ll keep it simple: you want to utilize silicone-based sprays for this project. While waterproofing sprays are available in a variety of forms and sizes, silicone is the most effective. silicone is used to seal bathtubs, sinks, and other areas where it is necessary to prevent water from leaking through.

When compared to a PU or acrylic coating, it penetrates the tent fabric entirely and does not rip off like the latter. To summarize, choosing silicone-based sprays is a no-brainer when it comes to long-term durability, safety, and waterproofness.

Type Of Tent Fabric

Finally, we have a selection of tent fabrics to choose from. Generally speaking, the majority of tents on the market today are constructed of one of three types of fabric: Another reason why you should choose silicone-based spray is because it is perfectly safe to use on all of the types of paint indicated above. If your tent has previously been coated or laminated, you should use a water-based spray to protect it because it will not damage the coating or lamination.

How to Waterproof Your Tent

What do you do now that you’ve obtained the waterproof spray? A tent’s watertightness may be achieved with relative ease. It’s a straightforward three-step procedure that goes as follows: You must complete some preliminary work before you can begin. Start by cleaning your tent to remove any dirt and grime that has accumulated on it. If you apply the spray on top of filth and grime, it will result in a poor seal and will not function properly as a result. Once your tent is clean, set it up (if you haven’t already) and start spraying it down with a water-based cleaner.

Make sure to distribute the water as evenly as possible, and pay special care to waterproofing the seams.

Cure the tent for the specified amount of time specified in the directions before packing it up or using it.

Congratulations, your tent is now completely watertight!

How to Make Your Waterproofing Last

After you’ve waterproofed your tent, you’ll want to make sure it lasts as long as possible. We understand that you don’t want to have to go through this entire process every time you want to use your brand new water-resistant camping tent. Once you have let it to dry and cure properly, make sure to keep it in a safe location. Storage in a cool, dark location, such as a closet, is recommended. Keep it out of direct sunlight if at all possible. If you don’t use it for an extended period of time, make sure to inspect it for mold on a regular basis.

Make careful to fix any damage to the waterproofing as soon as it occurs to avoid the situation becoming worse later on.

Another smart tip is to always have a backup can of waterproofing spray on available, just in case something happens to the first can.


Since publishing this post, I’ve gotten a flurry of letters from readers who have inquired about the intricacies of tent waterproofing. Because many of the same questions are asked over and over again, I decided to create this FAQ section to address the most often asked topics.

Does a new tent even need to be waterproofed?

The quick answer is: it depends. It is dependent on the situation. While most tents manufactured in the last several years are expected to be waterproof from the factory, some of the lower-cost models are not guaranteed to be so.

When you factor in the fact that these sprays are quite inexpensive and simple to use, you’ll find that you’re not losing anything by waterproofing your tent with them.

How often should you waterproof your tent?

It all depends, yet again. If you live in a wet region of the nation, such as the Pacific Northwest, and you go camping regularly (every month or so), you may need to renew your camping license on a yearly basis. As a casual camper who camps many times each year in fair weather circumstances, on the other hand, you should be able to extend the life of your waterproofing for several years at a minimum.

What’s the difference between seam sealing and waterproofing?

Depending on the situation, once again. Camping in a wet region of the country (like the Pacific Northwest) on a regular basis (every month or so) may necessitate doing it on an annual basis. As a casual camper who camps many times each year in fair weather circumstances, on the other hand, you should be able to extend the life of your waterproofing for several years at a minimum.

Our Verdict

Nikwax TentGear Waterproofing Spray is the best tent waterproofing spray on the market, and it will ensure that you are never caught off guard in the rain again. A wide range of textiles, such as tents, tarps, shoes, coats, and many others, are effectively waterproofed using this product. Consider how liberating it would be to never have to worry about getting wet when camping again. This sounds fantastic to me! Take the initiative and use this waterproofing spray before you depart, and keep an additional can on hand in case of an unexpected leak or leakage.

How to Waterproof a Tent

The product has had 274 reviews, with an average rating of 4.4 out of 5 stars The sound of water trickling into your tent is one of the sounds of nature you don’t want to hear while you’re camping in the outdoors. If you’ve been through it, it’s time to reinforce the waterproofing of your shelter’s foundation. There are three different methods for waterproofing your tent:

  • Seal the seams: Using a seam sealant can help prevent moisture from leaking through the seams. The urethane coating on the interior of your rainfly and the floor of your tent are the principal barriers against moisture
  • Thus, it is important to keep them in good condition. Refresh the DWR: A durable water repellent (DWR) coating helps your rainfly drain water
  • Nevertheless, it can become brittle with time.

Video: How to Waterproof a Tent

A lot of tents are sold with seams that are sealed, but the sealant can wear out with time, allowing water to seep through the seams. If you discover a leaking seam, you’ll need the following supplies:

  • A rag, rubbing alcohol, seam sealant (be sure you acquire the proper type for your tent), and a pair of scissors are all needed. Cloth that has been silicone treated requires a different sealer than fabric that has been polyurethane coated. However, if you’re not sure what sort of fabric your tent is made of, you should check with the tent manufacturer.)
  • The majority of tents are made of polyurethane-coated textiles, but if you’re not sure, check with the tent manufacturer. Optional: a drop cloth to collect spillage

The following are the steps to seal seams:

  1. Set up your tent in a dry, sunny location or a well-lit room so that you can readily inspect all of the seams and gussets. Sew the underside of the fly and the inside of the tent body together to create a watertight seal. It is beneficial to put the fly on inside out so that you can get to the seams more easily. Remove any peeling parts of seam tape from the underneath of the fly, but leave the sections that are still in place if you locate any loose seam tape on the underside of the fly. Prepare the seams by carefully cleaning them with a cloth and rubbing alcohol before sewing them together. Then, using the new seam sealant, seal the seams. If one seam is beginning to break, it’s possible that the rest may follow suit soon after, therefore it’s a good idea to apply seam sealer to all of them. Allow the seam sealer to dry completely before using it.

Refreshing the Urethane Coating on a Tent

If you’ve observed anything peeling off of the interior of your rainfly or on the floor of your tent, it’s time to apply a fresh layer of urethane coating to the surface. Here’s everything you’ll need to get started:

  • The following items are required: a sponge with an abrasive side
  • Rubbing alcohol
  • Tightening agent (again, be certain to use the correct type for your tent). Cloth that has been silicone treated requires a different sealer than fabric that has been polyurethane coated. However, if you’re not sure what sort of fabric your tent is made of, you should check with the tent manufacturer.)
  • The majority of tents are made of polyurethane-coated textiles, but if you’re not sure, check with the tent manufacturer.

The following is the procedure for applying tent sealant:

  1. With rubbing alcohol and a sponge, carefully clean the peeling coating off your rainfly and/or tent floor. Follow the directions on the container of tent sealant to apply a thin coat of the new tent sealer to the whole fly or tent floor
  2. Allow at least 24 hours for the new coating to cure before removing your tent from the ground. To eliminate any residue from sealant and coated tent materials, wash your hands well.

Refreshing the DWR on a Tent

If the rain is no longer beading up on your fly, you may reapply the durable water resistant (DWR) coating. Here’s everything you’ll need to get started:

  • A water-repellent substance that may be sprayed on
  • Water
  • A clean, moist cloth
  • A clean, damp cloth

The following is the procedure for applying the waterproof spray:

  1. Assemble the tent and clean the rainfly (if you just washed your tent, you don’t need to wait for it to dry before adding a fresh DWR coating)
  2. Spray the outside of the rainfly with the waterproofing spray, ensuring that it is uniformly coated. After a couple of minutes, use a moist towel and wipe away any extra coating that has accumulated. Prior to packing up the tent, allow it to thoroughly dry out.

Water-Repellent Treatments are available for purchase.

Best Waterproof Tent Sprays

We utilize affiliate links, and we may gain a small profit if you make a purchase via one of them. More information about us may be found here. When I was a child, we used to spray our hunting boots with waterproofing to ensure that they lasted as long as possible. To be honest, I’m not confident we used the proper sprays or applied them correctly, but Dad claims it was beneficial. Later in life, I began guiding hiking excursions, and we used similar sprays to keep our tents and equipment watertight.

Do not worry, I will not allow you to become lost in the maze of options available to you.

By the end of this essay, you should have a better understanding of what to look for and what to keep in mind when purchasing.

I’m also going to get right into it and recommend a few of the best waterproof tent sprays you can use to rejuvenate your tent or increase its water resistance without wasting any time.

Our Top Waterproof Tent Sprays 2022

We have chosen this as our top selection for the finest waterproof tent sprays available in our review. It’s readily accessible at your local shop or online, and it’s dependable, economical, and simple to operate. When it comes to waterproofing sprays, it doesn’t get much better than this in terms of effectiveness.

  • Silicone-based protection in a 10.5-ounce aerosol container that is widely accessible.

The Kiwi Camp spray may be found in the outdoor area of your local supermarket, and while some of the brands on our list are new or obscure (which does not imply that they are ineffective), the vast majority of you will be familiar with it. As a result, hikers on lengthy excursions or thorough hikers who arrive in town with tents that are beginning to leak should be able to get this identical product with a fast trip to the local store. Fortunately, it’s also the most widely used waterproofing spray on our list, which is a bonus.

In addition, it is advised for use on shoes, tent materials, and other outdoor gear, so if you have any extra, go ahead and put it to good use!

2.Scotchgard Heavy Duty Water Shield

It is a 3M product, and that business is well-versed in the production of revolutionary home chemicals like Scotchgard. They are the ones who gave us our fondness for sticky notes and scotch tape. After all, it seems to reason that they would be able to produce some excellent waterproofing, right? Maybe.

  • Cans are either 13 ounces or 10.5 ounces in size
  • One coat application
  • Tents and outdoor textiles benefit from this product.

When I first started looking into this waterproofing spray, I came across a lot of conflicting information. Some users expressed dissatisfaction and lowered the overall rating, while others gushed about how well it worked. So I wondered how it could work so well for some people while failing so miserably for others. Further investigation revealed that customers who were unsatisfied had attempted to use the product to waterproof an outdoor cushion, among other things. Of fact, spraying a pillow may make the exterior fabric more resistant to water, but it will not prevent the interior fibers from becoming saturated in the process!

With a single application, the spray may efficiently restore waterproof protection on thin nylon and polyester textiles such as tents, making it an excellent solution for use on thin nylon and polyester fabrics.

More information is available at Amazon.

3.Atsko Silicone Water-Guard

Over the years, I’ve worked for a number of different guiding firms, and fixing equipment has always been a part of the job.

However, I’ll be the first to say that I’d never heard of Atsko until I began conducting extensive study on the subject. Now I wish I’d known about it years ago when I first started looking!

  • Protection against water based on silicone
  • Effective on all current outdoor textiles
  • 10.5 ounce aerosol spray bottle

In a similar vein to the issue with the Scotchgard, I had to do some investigating before I discovered that many of the negative reviews for this product are the result of individuals who have used it incorrectly. It is not a magical waterproofer, and it will not make items waterproof that were not intended to be waterproof in the first place, as previously stated. Having said that, it is ideal for our purposes! Based on our buyer’s guide, you should already be familiar with the procedure for checking and repairing seam sealant damage.

You should allow 72 hours for this spray to cure completely, so leave the tent built in a sheltered place for three full days before putting it up.

More information is available at Amazon.

4.Gear Aid Revivex Instant Waterproofing Spray

McNett is a fantastic brand, and their seam sealing solutions are some of my favorite to use. Consequently, you’d expect them to produce an excellent waterproofing spray as well, wouldn’t you? Let’s have a look and see!

  • Silicone and PFOA are not present
  • The product may be used on paper maps. 5 ounce aerosol spray bottle

I’ll confess that I’m apprehensive about any waterproofing that isn’t silicone-based on outdoor materials. However, this does not rule out the possibility of success. Furthermore, because of the moderate waterproofing compounds in this spray, you may even put it on paper maps to make them water resistant! As a last remark, make certain that you get enough of these cans to protect bigger tents and structures. The 5 ounce bottle isn’t going to be able to cover a large amount of ground. To be quite honest, having such a tiny quantity in a can seems a little wasteful.

This product is best suited for tiny tents or outdoor materials that require waterproofing replenishment.

5.Atsko Sno-Seal Water-Guard Extreme Repellent

Last but not least, we have another Atsko spray, but this time it comes with a few extra punches that we haven’t seen in any of the other sprays we’ve tried so far. If you’re concerned about your budget, you’ll be surprised to learn that it’s still pretty reasonable and comparable to the other sprays on our list.

  • 10.5 ounce aerosol with no silicone
  • Sun and mildew resistant
  • Non-silicone-based

Is there yet another silicone-free waterproofing spray on our shopping list? Gasp! But, more importantly, does it truly work? Yes! Atsko appears to hit the mark almost every time with their waterproofing solutions, and this particular one is great for the additional protection it provides. It has been precisely developed to not only restore waterproofing, but also to defend against UV rays and fungal growth. Tent materials such as nylon and polyester get discolored and degraded over time as a result of ultraviolet radiation and mildew.

It is recommended that you apply this product once a year to protect your tent against water, sunlight, and mildew buildup. More information is available at Amazon.

How to Choose the Best Waterproof Tent Spray for You

If you’re looking for a waterproof tent spray, there are typically two techniques of application to choose from. Sprays are available in two forms: pressurized aerosol bottles and spritzer bottles, which are used to apply the product with your hands. Aerosol bottles are often made of metal cans that have been pre-pressurized with a gas of some kind before being used. Fortunately, today’s industries are more conscientious about the sorts of materials that are used to pressurize these bottles, but in the past (and to some extent still today), aerosols were notorious for being pressured with harsh chemicals.

The spray bottle is a traditional home cleaner container with a little hand spray lever on the side.

The drawback of hand spray bottles as compared to aerosols is that aerosol applications may be tailored to generate a considerably finer mist of particles than hand spray bottles.

Silicone Based Sprays

In fact, as we’ll discuss later, silicone compounds are the most effective waterproofing agents for tent materials. In the home, silicone is a soft, water-resistant substance that is utilized in a variety of products – including oven mitts! While there are many other types of waterproofing sprays available, the majority of the finest ones for use on tents are silicone-based products. Caution should be exercised to avoid unintentionally purchasing a “stain resistant” spray intended for use on clothing.

For the most part, tent waterproofing or boot waterproofing sprays provide a considerably thicker, heavier coating of waterproofing material than sprays intended for stain prevention on garments.

Understanding Tent Fabrics

The quality of your waterproof tent spray will be strongly influenced by the quality of the materials you choose to make it. There are various different varieties of tent fabric, and knowing what each one is can help you understand what you’re getting yourself into when you go camping. Nylon and silnylon are man-made textiles that are very similar to the same material that is used in the production of plastic bags. Upon processing, this material is transformed into fibers that may be woven together to form nylon fabric in a variety of thicknesses.

  1. This silicone is a critical component of the fabric’s waterproofing properties.
  2. It is less elastic than nylon when subjected to loads and when damp.
  3. Both silnylon and silpoly create excellent tent bodies, but the quality of the fabric and the silicone impregnation are critical components of the overall image that are frequently difficult to discern.
  4. A less common but still essential tent fabric called asDyneema CompositeorCuben Fiberis even more waterproof than either silpoly or silnylon, and it is used in military and commercial applications.

This lightweight fabric is likewise quite pricey, but it is comprised of a totally waterproof impermeable sandwich of plastic mylar and dyneema fibers that is completely waterproof and impermeable. Cuben fiber does not require the use of waterproofing spray.

Duck Cloth Tents

The following is a warning to those of you who may be utilizing old military surplus equipment, such as the old duck fabric tents. There is no way to make your tent watertight with one of these waterproof sprays. Waterproof sprays such as this one function by depositing a coating of waterproof substance on the surface of the cloth that has been chemically bonded. This is particularly effective on very tightly woven textiles such as contemporary nylon and polyester. Comparing cotton and duck cloth canvas to nylon and polyester, the space between each fiber is huge on textiles with larger weaves, such as cotton or duck cloth canvas.

Difference Between Seam Sealing and Waterproofing Spray

You’re most likely looking for waterproof tent sprays because you’ve discovered that your tent is leaking water. Will waterproof tent spray, on the other hand, genuinely be of assistance? Before using waterproofing spray, make certain that the leak is not originating from a puncture or a rip in the fabric. Punctures are simple to detect and can be caused by a variety of objects such as twigs, branches, tent poles, or stumbling. It is possible that leaks around the seam of your tent are more difficult to detect.

Even if you don’t use the tent, this tape will eventually lose its stickiness and begin to pull away after a number of seasons.

Silicone seam sealing may be performed at home or in a manufacturing setting, and the results are often far more satisfactory.

The following procedure can be used to repair old seam tape that has begun to tear away.

How to Apply Waterproof Tent Spray

There are a few basic actions you can take to ensure that your waterproof tent spray gives you the best results possible.

  1. Make a temporary home for your tent outside in the sun for a few hours until it is entirely dry. Bring your tent into the garage or another covered place where it will receive the least amount of wind and sun exposure (direct sunlight can be harmful to the waterproofing chemicals)
  2. Brush on in broad, even strokes, overlapping each pass by an inch
  3. Don’t go overboard with the spray! Drips and runs should be avoided at all costs. You could move your spray quicker or back off a few inches if you observe a buildup of surplus spray on the fabric. Please allow your tent to dry overnight before tearing it down and removing its contents

It is also OK to use more than one coat of waterproof spray on the surface. As many times as necessary, if you believe your tent need additional waterproofing or if one layer does not provide adequate protection, repeat the process.

Can I Waterproof a Tent That Wasn’t Already Waterproof?

The short and simple answer is no. If you purchase a shoddy tent that is not constructed of high-quality waterproof materials, no amount of waterproofing spray will be effective against the elements. Even if your tent was originally waterproof and is only needing a little help getting back on track, waterproof spray should be able to help it last a few more seasons. Make certain that the manufacturer’s statements are supported by evidence in order to prevent this situation.

If you are looking to purchase a tent and the manufacturer does not specify what type of waterproof fabric the tent is made of, then you should pass on the purchase. It’s possible that it’s garbage.


Unfortunately, the solution is both lengthy and convoluted. It is essential that the outer layer of nylon or polyester remains dry in order for breathable materials to function correctly (or at least not saturated). The water resistance of waterproof and breathable clothes on the upper layer may diminish with time, causing them to “wet out.” Once this occurs, the garment will retain its waterproofing properties but will lose its breathability. It’s better to use a DWR treatment that can be applied after the fact to restore breathability.

Do these sprays smell bad?

That’s a good question. Yes and no, is the answer. When they are initially sprayed on, the majority of them have a faint odor. During the 24-72-hour period when they are curing, the odor should nearly completely gone. All of the sprays on our list should have a faint or non-existent fragrance once they have been dried. Depending on how quickly you spray your tent and then pack it up before the spray has had a chance to properly dry, the tent may continue to smell for some time.

How many coats of spray should I use?

For the majority of the high duty silicone based sprays on our list, one thick application should be sufficient protection. Adjust your spray distance and speed to apply a beautiful thick coating of paint, but avoid getting the cloth so wet that you get drips and runs on the surface. Using a heavy application method such as this should produce in satisfactory results after only one pass over the whole tent fly surface.


When it comes down to it, it’s generally preferable to invest in a new tent that includes a high-quality rain fly to ensure that you stay dry. However, that is too expensive, and the majority of us are unwilling to fork up the cash! Waterproof tent spray is available for as little as $5, and it may be able to extend the life of your tent for another season. It’s possible to restore the quality of your rain fly if you follow our buyer’s guide and read the reviews to choose the finest waterproof tent spray for your equipment.

However, if you understand the limits of waterproof tent spray and utilize it as a preventative measure, you may assist to extend the life of your gear significantly.

Tent Waterproofing: Top Tips on How to Waterproof a Tent

It may seem bizarre to have to waterproof tents since one of its primary functions is to keep the rain out, but tent waterproofing is a necessary evil.

Even the highest-quality camping tents, however, can degrade with time and lose their ability to protect the user from the elements. In order to give your wilderness home a little TLC, you’ll need to know what you’re doing and how to waterproof a tent when the occasion arises.

Why do you need to waterproof a tent

The majority of half decent tents are waterproof when you purchase them; nevertheless, there are some low-grade tents on the market that simply pretend to be water-resistant when purchased. These tents are not waterproof in any way, and they will begin to melt as soon as there is even a slight suggestion of moisture in the air. Not nearly, to be honest. However, when the wind picks up and the rain starts pouring, they will almost likely be insufficient protection. In this case, applying a tent waterproofing treatment will not make the tent impermeable, but it will increase its water resistance.

Sun damage

Just as dangerous ultraviolet (UV) rays may cause irreparable damage to human skin, so too can continuous exposure to the sun cause irreversible damage to textiles and other materials. Even a couple of weeks of camping in the hot summer heat may do severe damage to your tent’s fly sheet, limiting its ability to withstand heavy rain and other elements. One of the most effective strategies to extend the life of your tent is to keep it out of the sun as much as possible. If you want to camp in sunny areas, continue reading to learn how to do it safely.

Use and age

It is inevitable that fabric that is continuously beaten by the weather, that is coated in filth and dust, that is left to dry out in the sun, and that is then folded up in a bag and left for months, will degrade. As a result of the weather and dirt, water gets absorbed into the fabric, making it less efficient against rain and wind protection. Tent waterproofing treatments, such as DWR coatings, assist to extend the life of tent fabrics by covering the surface of the fabric with a water-repellent coating.

Damaged seams

The strength of the tent seams will be compromised as a result of time and exposure to the environment. When you purchase a tent, the majority of them will have fully sealed seams. However, seals can become compromised with time, resulting in leaks at the seams. This issue can be resolved by using a seam sealer.

Identify the problem

Consider this: before you spend a lot of money treating the entire tent and all of its seams with pricey tent waterproofing treatments, figure out which section of your tent is not performing properly. Examine your tent during the next downpour, or put it up in your backyard and spray it down with water to check for the following things: Have you ensured that it is correctly installed? Tents that are improperly set up will not perform as well as they should. Take care to ensure that all of the guylines are properly staked out.

  1. In order to maintain a proper separation between the inner and outer fly, make sure the outer fly is staked out well.
  2. Is there any evidence of water leaking through the seams?
  3. If there is water dripping through the seams, you will need to reseal them using a seam sealer to prevent further water damage.
  4. It is necessary to pitch your tent on damp ground and then sit in your tent for a period of time in order to thoroughly test this.

Is there any evidence of water leaking through the main fabric of the tent fly? This is most often caused by use, age, and/or UV damage, and necessitates the use of a waterproof tent spray to remedy the situation. The tent appears to be missing a tarp.

How to waterproof a tent

Some individuals waterproof their tent after every few uses, while others do it on a more regular basis. Others may only do tent waterproofing once over the lifetime of their tents! Your tent’s waterproofing frequency is determined by the amount of time you spend in it, how well you care for it, and under what conditions you use it. We recommend that you do this at least once a year, at the start of the camping season.

01 Clean your tent

It is necessary to thoroughly clean your tent before using a tent waterproofing solution, seam sealer, or tent repair tape.

  • Set up your tent as soon as possible. Toss some mild detergent or a tech wash into a pail of warm water and set it aside. Clean it with a gentle sponge until it is completely clean, giving special care to the seams. Before drying the tent, spray it with a tent waterproofing agent.

TOP SUGGESTION: Do not wash your tent in the washing machine!

02 Apply a tent waterproofing treatment

  • Set up your tent as soon as possible. Make certain that the tent is clean and moist
  • Using a spray, brush, or sponge, apply the treatment to the tent fly from top to bottom. Any surplus product should be cleaned up with a wet towel. Allow it to dry completely before putting it away.

03 Seal the seams

  • Make sure your tent is clean and dry before you begin. Lay the tent out on a clean, level surface with the inside of the seams facing up
  • This will ensure that the tent stays dry. Apply a tiny amount of rubbing alcohol on a dry towel and wipe the seam to remove any remaining stains from the fabric
  • Remove any portions that are flaking away with care. Apply the seam sealer using a tiny brush in accordance with the manufacturer’s directions. Allow it to dry completely before putting it away.

The best waterproof tent sprays

Tent waterproofing solutions are available in a variety of various formulations. Some people choose to wash their tents in addition to treating them with waterproofing. Others include ultraviolet (UV) protection. Here are a few of the greatest alternatives:

Nikwax Tent and Gear Solarproof

  • One of the most effective techniques of tent waterproofing is really a preventive measure. As a result of the Solarproof treatment, the fabric is strengthened and protected against UV damage, in addition to providing water repellency and strengthening the fabric. Use of your tent should be preceded by the application of this product.

Kiwi Camp Dry Heavy Duty Water Repellent

  • In contrast to the Nikwax products, this Kiwi Camp treatment has a high concentration of chemicals. It is recommended to apply two applications for the optimum effects, and it may be used on objects other than tents.

Nikwax Tech Wash

  • Nikwax Tech Wash is generally used as a washing treatment for technical textiles, but it also has the added benefit of revitalizing breathability and water repellency. It is a good idea to include some waterproofing as a preventative measure

Star Brite Waterproofing Spray, Stain Repellent + UV Protection

  • In the same way as Nikwax Solarwash protects your tent before you use it, this product protects your tent before you use it. However, it should only be used after the tent is completely dry, and it may be used on a variety of various goods.

Scotchgard Outdoor Water Shield

  • Waterproof tent spray that is simple to apply and can be applied in a single application
  • It may also be used to provide water repellency to other items of outdoor gear.

Canvas waterproofing

Cotton canvas is used to construct some of the most comfortable and long-lasting tents for camping and glamping. Bell tents and teepee tents, for example, function exceptionally well in inclement weather. This high level of performance may be attributed to both the structural design and the durability of the canvas fabric. Camping enthusiasts have relied on cotton canvas for generations because of the inherent qualities of the fibers to make a highly waterproof fabric that has proven to be durable and long-lasting.

This is not due to the fact that they are defective, but rather due to the fact that the waterproofness of cotton canvas actually increases when it is wet.

Preventing your tent from becoming wet first can save you money on a time-consuming and expensive canvas waterproofing treatment.

It will become more waterproof when it has been allowed to dry.

Tent waterproofing with a tarp

It’s always possible to add a waterproof tarp to your camping set up if the notion of treating your tent with a chemical-based treatment isn’t appealing to you or if you’ve put off tent waterproofing until the last minute. Build a tarp over your tent in the same manner as you would normally, making sure that your entire tent is completely covered. Consider where the water from the tarp will be draining to, and make sure this area is free of gear, shoes, and other items of clothing. Tent waterproofing may appear to be a time-consuming task, but it will help to extend the life of your tent by many years.
