Best Tent Waterproofing Spray: Star Brite Waterproofing Spray

Star Brite Waterproofing spray comes in different size options but I would recommend going for the larger two if you have a tent bigger than 2 people. The smaller option covers 80 sq ft which is enough for most 4-person tents but will be cutting it close for 6-person+ tents.

Star Brite is highly effective and not only acts as a waterproofing agent but will also protect your tent from UV Rays on hot days. When applied, it dries with no odor or color and will protect your tent from leaking around corners and through the seams.

Because it’s a silicone based spray it will be perfect for your polyester, nylon, cotton, or canvas tents. If you are worried about the solution being too strong for your tent fabric you do have the option to dilute it with mineral spirits and you’ll get more bang for your buck.

Pros
  • 3 different sizes to choose from
  • Also protects against UV Rays
  • Dries odorless and colorless
  • Can dilute with mineral spirits
Cons
  • Only works for cotton, polyester, nylon, and canvas

Best Runner Up: Nikwax Tent and Gear Protection

The Niwax Tent and Gear Protection spray is another tent waterproofing product that will keep water from leaking inside your tent and it will protect your tent from UV Rays. You also get a choice of two different sizes depending on the size of your tent. The Nikwax is a water based and biodegradable spray so you can feel comfortable covering your entire tent without any harmful chemicals. The trigger spray requires some more physical work to waterproof your tent because of the need to hand pump as opposed to an aerosol option but the product is a great waterproofing agent for camping outdoors during rainy weather

Pros
  • Protects against UV Rays
  • Water based and biodegradable
  • Choice of 2 different sizes
Cons
  • Trigger spray nozzle

Best Tent Waterproofing Nozzle: Kiwi Camp Dry Heavy Duty Water Repellent

Kiwi is no stranger to tent waterproofing products and the Camp Dry Water Repellent is a perfect choice for spraying down your tent to prevent any leaks. It actually comes with two cans and works like a charm if used properly. Once applied you will want to let your tent sit outside anywhere from 4-24 hours because it will give off a chemical odor that isn’t very pleasant. After that it’s smooth sailing in the outdoors because you don’t have to worry about rain ruining a nice, nature-filled weekend. There are few other options as highly touted and recommended as the Kiwi Camp Dry. 

Pros
  • Comes with two cans
  • Provides excellent waterproofing
  • Good for polyester, nylon, cotton
Cons
  • Gives off bad odor until dry

Scotchgard Heavy Duty Water Shield

With a choice from 13oz to 64oz the Scotchgard Heavy Duty Water Shield will provide enough spray to make sure your entire tent is waterproofed. All you have to do is easily press down on the spray nozzle in the direction you want and completely cover the surface of the material in Scotchgard. And you can use it on practically any surface like polyester, nylon, or cotton. To ensure you have enough waterproofing tent spray to cover your entire tent I would purchase one of the larger sizes because you will get about 10-20 sq ft for each can. You can feel a little more secure in the outdoors during a rainstorm using the Scotchgard Water Shield.

Pros
  • You can buy different sizes
  • Can use for cotton, nylon, and polyester
  • Dries odorless
Cons
  • 10-20 sq ft of use per can

Sof Sole Silicone Waterproofer Spray

The Sof Sole is a 12% silicone formula that can be used for a number of outdoor materials like polyester or nylon but works best for materials that are already waterproof like canopies or tents. The aerosol can make it easy to apply because the spray will come out evenly but you might have to buy more than one can in order to fully cover your tent. And I wouldn’t use it on just any fabric because it can cause some discoloration or diminish the functionality for materials like gore tex or athletic shoes. But if you plan on using it for your tent then you can rely on it to protect you from water leaking through the seams while you’re sleeping.

Pros
  • 12% silicone formula
  • Good for polyester or nylon
  • Easy to apply
Cons
  • Can cause discoloration on wrong fabrics

NeverWet 11-Ounce Outdoor Fabric Spray

The NeverWet Outdoor Fabric Spray is not as well known as some other brands of outdoor water protection but there’s no denying its an effective tent waterproofing product. The trigger spray nozzle is more work than an aerosol option but you still get the same even coating. You can use it for polyester, cotton, and canvas and you get at least 20 sq ft of coverage per bottle but you’ll probably have to get a couple of bottles to cover your entire tent. If you’re looking for a reliable choice to protect your tent from rainy weather then the NeverWet will keep you dry outside.

Pros
  • Can use for polyester, cotton, and canvas
  • 20 sq ft of coverage
Cons
  • Trigger spray nozzle

Better Boat Waterproofing Spray Fabric Protector

The Better Boat Waterproofing Spray is a very versatile product that when used for your tent will ensure full protection from wet weather. It works well on canvas, polyester, and nylon so any tent material should be able to work with the Better Boat. It’s one of the bigger sized bottles on this list but the price still competes with some of the other, smaller bottles. The Better Boat brand is more well known for protecting boat canvas or marine materials but if used on your tent it will keep you dry in any weather.

Pros
  • Works well with canvas, polyester, and nylon
  • Very versatile product
  • Bigger sized bottle
  • Great price for size
Cons
  • Used more for boat canvas

Atsko Silicone Water-Guard

Not as well known as some of the other brands in tent waterproofing products the Atsko Silicone Water-Guard is still as effective as any other options on this list. And it’s also one of the cheapest waterproofing products that you will find. The aerosol spray makes it incredibly easy to treat your tent without making a mess or requiring lots of hand pumping. You can use the Atsko on several different types of fabrics like polyester, nylon, canvas, and others. It can take some time to dry but once it does you’ll be surprised at how effective it is compared to other, more well known brands. 

Pros
  • Very affordable
  • Aerosol spray nozzle for easy application
  • Can use on polyester, nylon, canvas and more
Cons
  • Long time to dry

What Makes A Great Tent Waterproofing Product

Application

The two types of application you’ll find on the list below are the trigger spray and aerosol spray nozzles. 

The trigger spray is the more conventional method and acts like a water bottle spray where you hand pump the trigger.

You’ll get an even spray using the trigger mechanism and more control over how much you are using to cover your tent. Downside is you might wear out your index finger trying to cover your whole tent.

The aerosol nozzle is much easier to apply because all you need to do is point the nozzle in the direction you want to spray and push down. You have a steady stream of waterproofing solution covering your entire tent.

Waste is a concern when using the aerosol option because of the lack of control. Purchase an extra can or two before you start.

Cure Time

Every waterproofing product for tents needs time to dry in order to fully protect you from rainy weather. But if you don’t allow your product to fully dry you could run into issues with retaining a chemical odor or discoloration.

Some products only require a few hours to dry but others will require a few days. Make sure you know how long your product is going to take to cure before taking it outdoors so you can give yourself plenty of time to set everything up. 

Type of Fabric

Some of the products on this list are water based and some are silicone based. The water based products will typically be better for fabrics that already have glue with adhesive or for “laminated” or “coated” fabrics. This is because the product won’t dissolve any of the glue or extra coating used to cover your tent.

But the silicone product can have a negative effect and should only be used for fabrics that are 100% polyester, canvas, or nylon. 

If your tent is built for rainy weather and you apply a waterproofing spray you’ll be fully protected from a storm of any severity.

Summary

My choice for the best tent waterproofing product is the Star brite Waterproofing Spray for its large sq ft coverage and versatile protection. You get UV protection included in your waterproofing product and it fully protects polyester, nylon, or canvas materials. And the 80 sq ft coverage is the largest on the list. If you want to make sure you’re going to stay dry in the outdoors and you want the best option in the market then the Star Brite will deliver.
