Kiwi Camp Dry

Kiwi Camp Dry Heavy Duty Water Repellent, 2 - 10.5 oz cans

Kiwi Camp Dry is a silicone-based waterproofing spray that bonds the fabric of your tent together to form a tough waterproof layer. It can be used on all your outdoor gear (bar performance fabrics), so if your tent is polyester, this spray will be fine, but it works best on nylon.

The spray doesn’t contain any harmful substances that could impair your health like fluorocarbons or VOC’s but it does contain isobutene and propane which aren’t very eco-friendly.

Applying it is easy, just spray it on your tent. You will have to do two coats for it to be 100% effective and the drying smell isn’t very nice, it smells a bit like paint. The good news is that once dry it is odor-free, so as long as you dry it out, you’ll be able to camp without any toxic smells.

Once applied it does soften the tent fabric and it retains breathability so you can rest assured you’re not going to start overheating in the night.

Pros

  • It maintains the breathability of your fabrics
  • Doesn't contain harmful substances like VOCs or fluorocarbons
  • When applied it softens the fabric
  • It's silicone-based and will work with PU coated and silnylon tents too
  • Once it's dry it is odor-free for your next trip

Cons

  • There is a strong pain smell while drying
  • You'll need two coats of this
  • Uses non-eco-friendly isobutene and propane for the aerosol

Product Information

  • Weight: 0.6 lbs
  • For: Tents, backpacks, jackets, and shoes
  • Breathable: Yes
  • Best Use: Nylon

Scotchgard Heavy Duty Water Shield, Repels Water, Ideal For Outerwear, Tents, Backpacks, Canvas, Polyester And Nylon, 13 Ounces

The Scotchgard Heavy Duty Water Shield is an excellent choice if you want a long-lasting waterproof barrier but you’re going to have to sacrifice your eco-friendliness to get it and wait for a lingering chemical smell to pass before using your tent.

You can use this spray on pretty much any tent, from nylon to polyester but its best application is for canvas tents. it also works great on backpacks, umbrellas, outdoor furniture, and more.

Applying it is easy, just spray it on. You only need one coat of this stuff but you will experience a chemical smell that lingers and you won’t want to camp in that. It’s best to let it dry out until the smell is 100% gone.

Best On A Budget

Sof Sole Silicone Waterproofer Spray

Sof Sole unisex-adult Silicone Waterproofer Spray for Boots, Tents and Outdoor Gear, 12-ounce, Black, 3

Sof Sole Silicone Waterproofer Spray is one of the most affordable waterproofing sprays in the review and it works on any material that isn’t breathable.

In case you’re wondering, your rainfly, whether it’s polyester or nylon is not breathable in order to keep the rain out, but your inner tent is breathable, so do not apply it there.

The spray contains a 12% silicone formula that creates a durable and long-lasting waterproof bond. Not only does it repel water, but also oils and dirt to keep your rainfly clean.

Applying it is easy, just spray away but you will need to do 2 coats to ensure it’s effective. While applying, you’ll want to cover your mouth and nose so as not to breathe in the intense odors, plus we’d recommend drying it outside and make sure the odor has gone before your next camping trip.

It doesn’t retain breathability, so make sure you don’t use it on any performance gear like Gore-Tex or it will ruin its valuable properties.

Pros

  • Durable and long-lasting thanks to the use of silicone
  • Easy to apply, just spray it on
  • Repels oils, dirt, and stains as well as water
  • It's the most affordable but only by a few dollars
  • Great for use across any outdoor gear that is not breathable

Cons

  • You'll need to use more than one coat
  • it doesn't retain breathability so don't use it on performance gear
  • It has a horrid smell

Product Information

  • Weight: 0.7 lbs
  • For: Tens, outdoor gear, boots
  • Breathable: No
  • Best Use: Anything that is not meant to breathable

What To Look For In A Tent Waterproofing Spray

There are quite a few things to consider when buying a tent waterproofing spray and you’re going to need to get them all right to be a happy camper in the end.

As you can see from the products above, no two sprays are exactly the same and you’ll need to match your materials and personal preferences to the right spray for you.

What Material Is Your Tent Made From?

Some sprays work on all materials, whether they are breathable or not. Other sprays work just on nylon and others on anything that is not breathable.

The first thing you need to do is confirm what your rainfly is made of. Is it nylon, polyester, or canvas and is it breathable or not?

Once you know the answer to these questions you can narrow down the search to a few different sprays.

Eco-friendly or Not?

Some Tent Waterproofing Sprays are eco-friendly and bio-degrade, others contain harmful substances for the environment and as they shed off your tent over time, will go into the soil and water table. This is of course a personal choice to make, but if being ECO is important to you, there is only one choice, Nikwax Softshell Proof Waterproofing Spay.

Odors, Coats, Drying Time

Some of the Tent Waterproofing Sprays in the review are odor-less while applying and others are odor-less once dried. Make sure to read the reviews carefully and always make sure that any odors are fully gone before you go on your next camping trip, as some will be harmful to your health.

Some of the sprays will also require two coats to be fully effective and some dry faster than others, these are all personal choices that you need to make decisions around before you buy.

Versatility

When we talk about the versatility of Tent Waterproofing Sprays, we mean two things. Does it just repel water or more? And, how many fabrics does it work on?

Some sprays in the review just repel water, others repel water, dirt, and oils, and some even more than that. It;’s worth opting for one that repels more than just water because why wouldn’t you?

You should also think about what else you might want to waterproof like your Gore-Tex jacket, boots, or backpack. Some of the sprays are so versatile that they almost work on everything. If you’re looking for a waterproofing spray that works on pretty much every material out there and repels dirt, oils, UV, and fungus, then the Atsko Sno-Seal Water-Guard is the one for you.
