KIWI Camp Dry Heavy Duty Water Repellent

KIWI Camp Dry Heavy Duty Water Repellant (Pack of 2)
  • KIWI Camp Dry Heavy Duty Water Protect provides a tough, long lasting and breathable...
  • Ideal for tents, tarps, boots, hunting apparel, outdoor gear, boat covers and patio...
  • Treated material stays odor free after drying
  • Keeps water out while still allowing article to breathe
  • Silicone bonds to leather/fabric to create an extremely tough water barrier

Several other sprays are available to protect your tent, but Kiwi Camp is one of our favorites. For starters, its silicone-based protection will keep you dry, and it is a widely available product.

Not only is the Kiwi Camp waterproof spray reliable and easy to use, it’s affordable too.

If you need a quality silicone-based tent waterproofing product, this is an excellent option. Users rave about its effectiveness and how it can cover an entire large-sized tent with two thick coats of spray.

This 10 or 12-ounce bottle comes in handy for other outdoor gear as well, so go ahead and use any leftover up before buying another.

The mist applicator works really well and helps reduce any drips while coating the fabric.

Kiwi’s spray works great, but it takes a while to set. Therefore, you should wait the full time before testing if water is still beading on your tent for best results.

Before applying this product, do a spot test on your fabric to check if any staining occurs.

PROS

Material is odor-free after drying
Silicone-based
Use on a variety of materials

CONS

Not resistant to abrasion

Star Brite Waterproofing Spray

  • Does not change the breathabilty, color, or feel of fabric

  • 22 oz covers – 80 square feet coverage (Coverage may vary slightly depending upon...

Waterproofing your tent can be a pain, but the reward is worth it. Star Brite Waterproofing Spray is a great choice.

When appropriately applied, Star Brite will not only protect your tent from leaks but also UV rays. In addition, it dries odorless and colorless with no residue on the fabric of your tent. You can use your tent immediately after application.

Star Brite comes in a 22-ounce spray bottle, all the way up to a 128-ounce jug. If you have a tent larger than a 2-person tent, I recommend purchasing a bigger size. The 22-ounce bottle covers up to 80 square feet.

The large 128-ounce bottle covers up to 200 sq ft which is enough for most 4-6 person tents but may not be enough for a tent bigger than that.

It’s made with silicone and can protect your polyester, nylon, cotton, or canvas tents. One nice thing about this solution is that you can dilute it with mineral spirits to get the proper strength no matter what fabric or material you are working with.

PROS

Available in multiple sizes
Offers water and UV protection
Great for new fabrics

CONS

Gallon jug doesn’t come with a spray applicator

Gear Aid Tent Waterproofing Spray allows you to protect your gear in just a few minutes. The aerosol formula is silicone-free and PFOA(Perfluorooctanoic acid)-free, maximizing the breathability of tents.

Its small size makes it easy to pack everywhere so you can be prepared. You can even use it on things like topo maps. In addition, it is both silicone and PFOA-free, meaning it is not a harsh chemical. Just because it’s not silicone-based doesn’t mean it won’t work.

Gear Aid’s tent waterproofing spray kit allows you to maintain your outdoor equipment. The product is designed for tents but can also be used on a variety of fabrics. It is a great product to use when you want your outdoor gear, like tents and backpacks, waterproofed.

GEAR AID Tent Waterproofing Spray is a water-repellant concentrate that does a good job of preserving the waterproofing on waterproof and water-resistant material. The downside is that it is barely enough for one 2 person tent, let alone a larger family or cabin tent.

PROS

Silicone and PFOA free
Use on a variety of materials
Materials remain breathable

CONS

Might need more than one can depending on the size of your tent

Who doesn’t love scotch tape and sticky notes? 3M is the company to thank for these household staples. They are also responsible for waterproofing your tent with their product Scotchgard.

Scotchgard Heavy Duty Water Shield answers the call for many canvas tent owners. Scotchgard is affordable and safe to use on your outdoor gear, furniture, tents, patio umbrellas, etc. It can also waterproof both nylon and canvas tents.

On the downside, it’s not as effective as other brands because one container doesn’t go very far. Depending on the size of your tent, you could end up using two or more cans to spray your tent and protect it from the rain.

When you spray, it will make the material look wet. You need to soak the fabric on your tent in order for this product to fully work. This means you can’t just give your tent a light dusting. Hold the aerosol can about 6 inches away and apply a consistent amount of spray throughout all parts of your tent.

This stuff works well, but buy more than you think you will need to cover your tent. Worst case, you will have some leftover for another application down the road.

PROS

Works on a variety of materials
Leaves fabric breathable
Dries fast and odorless

CONS

One can doesn’t go very far

Atsko Silicone Water-Guard

Sale
Atsko Silicone Water-Guard 10.5 oz
  • Restores factory waterproofing
  • Suitable for use on footwear and clothing
  • Fully cures in 72 hours
  • Suitable for outerwear, foot- wear, tents, sleeping bags and suede for all types
  • Allows material to breathe

Atsko Silicone Water-Guard is great for restoring factory waterproofing. But, unfortunately, you can’t use this on any old tent and expect it to be waterproof.

This stuff works best when used sparingly. Soaking the fabric with this waterproofing spray is unnecessary and wasteful, so try to be smart about using it.

To avoid inhaling harmful chemicals while you spray, wear gloves and a mask and spray outside. If possible, give the tent a couple of days to dry out thoroughly. You should also be aware of an unpleasant smell that will go away in about hours.

The Atsko spray dries clear, so don’t worry about over-spraying and people making fun of your mistakes. It’s great if you are on a budget since one can go a long way and rarely need a second coat.

This waterproofing spray is excellent for your camping gear. It doesn’t have a bad smell like other sprays and dries clear. It works great on shoes, tents, rain flies, umbrellas—and any more apparel or equipment that needs protection from rainy weather.

PROS

Suitable for different materials
Handy 10.5 ounce can
Easy to apply

CONS

Takes 72 hours to cure

Sof Sole Waterproofer is a 12% silicone solution that provides a durable, long-lasting waterproof bond to repel water. Its easy application is ideal for use on hiking or work boots, tents, and outdoor gear.

Sof Sole should not be used with breathable technical fibers such as gore-tex or athletic shoes because they could discolor over time. It works best on tents and other fabrics that are already waterproof.

The Sof Sole Tent Waterproofer Spray is versatile and durable. It can be sprayed onto hiking boots, tents, or other gear made of nylon or polyester to repel water as well as dirt and oils. However, the silicone in this spray may discolor some fibers like gore-tex, so it’s not recommended for these uses.

It’s easy to apply with the aerosol can, but you might have to buy more than one can for your tent. The spray comes out evenly and protects against water leaking through seams which can help you sleep easily.

However, Sof Sol can cause discoloration and potentially decrease the functionality of materials like gore-tex or athletic shoes. So take a little bit of caution before you go around spraying all your gear.

PROS

Great for outdoor gear

CONS

Not recommended for breathable technical fabrics

How to choose the best tent waterproofing spray

Tent waterproofing spray can be an excellent way for you to protect your tent from the elements. Whether it is rain, wind, or humidity that worries you, there are plenty of options on the market to choose from. The key will be finding one that suits your needs and budget.

Tents have factory-sealed seams, which can wear off over time, letting water through. Or you might notice some material flaking off your rainfly, which indicates it’s time to reapply your waterproofing agent.

Here are some things to keep in mind as you search for the best waterproofing spray.

What type of fabric is your tent made of?

Understanding what your tent is made of will help determine which spray or sealer is right for you. Most tents on the market are either canvas, polyester, or nylon.

The type of material your tent is made of can play a role in how effective your tent spray is. If you don’t know what material your tent is made of, it’s best to contact the manufacturer and see what type of spray they recommend.

Silicone vs. non-silicone tent spray

It’s important to get the right kind of spray for your tent. For example, if your tent is made from polyurethane-coated fabric, you will need a different product than silicone-treated fabric. Fortunately, most tents are poly-coated, but if you don’t know, check with the manufacturer.

A waterproofing spray that uses silicone effectively protects your tent fabric from water and staining liquids.

Many waterproofing sprays are created with silicone, which delivers a few benefits to tents. It prevents water from touching the fabric and repels any oil-based or staining liquids that may otherwise damage your tent.

Silicone can impact color, so always test on an inconspicuous area before using it.

Spray bottle vs. aerosol

We are all familiar with aerosol cans, from hair spray to sunblock. It’s so easy to use an aerosol spray to waterproof your tent. You get a pretty even coating without much effort.

You simply spray on the product, let it dry, and you are done. The key will be to make sure your tent is clean before applying any spray or sealer to it.

One downside to aerosol cans is that you can end up using a lot more products than you anticipated.

Some people prefer sprays in a bottle because they can control how much is being sprayed onto their gear. However, instead of using an aerosol can, you need to make sure the liquid is not too thick, or it won’t dry up all the way.

This may lead to a bit of residue, which will need to be cleaned off later.

Seam sealing vs. waterproofing

Although many tents come with sealed seams, the sealant can wear out over time, letting water leak through.

A seam sealer is a glue that absorbs into tent fabric and improves its water repellency. You use it to close leaks in the material of your camping gear, like tents or sleeping bags.

Before you go with waterproof spray, make sure you note where the leak is coming from. The two common types of leaks are punctures and seams; both can easily be identified if you look closely enough.

Punctures happen when sharp objects pierce your tent’s material while it’s being used, like sticks, branches, rocks, etc. On the other hand, seams might need some more attention because they can deteriorate over time due to extended exposure to weather conditions.

You can use a seam sealer to seal these areas if you find holes forming. Seam sealer is a solution that you brush onto the area to penetrate and fix the holes.

A waterproof spray can be a great preventive measure, but if you have bigger problems, you may not get what you expect out of waterproofing spray alone.

How to waterproof your tent

Waterproofing your tent is not super difficult but does require some work. The best way to waterproof your tent is to follow the steps on the product you bought.

Here are some general tips to make your tent water repellent:

First, clean your tent before coating it with any type of spray, especially if there is already any existing dirt or grime. Some waterproof sprays are applied while the tent is wet, so it’s important to read the instructions before you begin.

In other cases, you need to make sure the fabric is completely dry before using your waterproofing sprays. Otherwise, the water-resistant properties will not work to full effectiveness.

Read the instructions carefully and make sure you apply the waterproofing spray in a well-ventilated area.

What about a rainfly?

The rainfly is your first line of defense when it comes to staying dry in your tent. Therefore, it should be as waterproof as possible. If you have a rainfly, make sure you are sealing that separately from the rest of your tent.

The rainfly can take a beating from the rain, wind, sun, etc., so you need to make sure it’s also in good condition. If your tent does not come with a rainfly, contact your manufacturer and see if you can buy one from them.

You can also set up a tarp over the top of your tent to prevent any water from seeping in.

Camping in wet conditions

I have camped in rainy, wet conditions more times than I care to count. Sometimes the rain is expected and other times not so much. I have slept in crappy old tents that barely passed as a tent. I have woken up in a soaking wet sleeping bag in several inches of water.

Some tents are better than others, and you can’t just take any crappy old tent and magically make it waterproof. It is also important to pay attention to where the leaks are and address the source of the problem.

You can spray a tent to get an overall protective layer, but sometimes you might not know there is a bigger problem.

Waterproofing and sealing a tent (and rainfly) are a good defense against waking up soaking wet.

Conclusion

When it comes to the best tent waterproofing spray, you must know what type of material your tent is made out of. The most common types of sprays are aerosol cans or bottles, but they’re a variety of different factors when considering which one will work for you.

Whether your goal is simply trying to prevent leaks from happening in the first place or if you want something more heavy-duty like a seam sealer, you should know what will work best for your needs and own preferences.
