8 best waterproffing for tents

With the arrival of the summer months, you may be planning your first outdoor excursion in a long time – and you’ll want to be sure there are no unpleasant surprises waiting for you when you arrive at your campground.


The good news is that most tents have a waterproof membrane or have been treated with a waterproofing compound to prevent rain from soaking through the fabric.


However, this coating will wear away over time and will need to be replaced with tent waterproofing spray — if you don’t, you and your belongings may wake up soaked after a rainfall!

Fabric Types

Some of the items on this list are silicone-based, while others are water-based. Water-based treatments are often preferable for fabrics that already have glue or adhesive, as well as fabrics that have been “laminated” or “coated.” This is due to the fact that the product will not remove the glue or additional coating applied to cover your tent.

However, the silicone product can have a detrimental impact and should only be used on 100% polyester, canvas, or nylon textiles.

1) Star Brite Waterproofing Spray.

Star Brite Waterproofing Spray comes in three sizes, however if you have a tent with more than two people, I recommend going with the larger two.

Star Brite is a highly effective waterproofing treatment that also protects your tent from harmful UV rays on hot days.

It’ll work great on polyester, nylon, cotton, or canvas tents because it’s a silicone-based spray.


  1. 3 different sizes to choose from
  2. Also protects against UV Rays
  3. Dries odorless and colorless
  4. Can dilute with mineral spirits


  1. Only works for cotton, polyester, nylon, and canvas

2) Nikwax Tent And Gear Protection

2) Nikwax Tent And Gear Protection

Another tent waterproofing product is Niwax Tent and Gear Protection Spray, which keeps water from leaking into your tent and protects it from UV rays.

Nikwax is a water-based, biodegradable spray that you may use to cover your entire tent without worrying about dangerous chemicals. Because you must manually pump the trigger spray instead of using an aerosol, it involves more physical effort to waterproof your tent, but it is a wonderful waterproofing solution for camping outdoors during rainy weather.


  1. Protects against UV Rays
  2. Water based and biodegradable
  3. Choice of 2 different sizes


  1. Trigger spray nozzle

3) Kiwi Camp Dry Heavy Duty Water Repellent


Kiwi has a long history of producing tent waterproofing treatments, and the Camp Dry Water Repellent is an excellent choice for spraying down your canvas to prevent leaks.

After that, it’s easy sailing in the great outdoors because you won’t have to worry about rain spoiling a relaxing weekend in the woods.



  1. Comes with two cans
  2. Provides excellent waterproofing
  3. Good for polyester, nylon, cotton


  1. Gives off bad odor until dry

4) Scotchgard Heavy Duty Water Shield


The Scotchgard Heavy Duty Water Shield, which comes in sizes ranging from 13oz to 64oz, will give enough spray to waterproof your entire tent. Simply press down on the spray nozzle in the desired direction to completely cover the surface of the material with Scotchgard.

You can use it on almost any surface, including polyester, nylon, and cotton. I would get one of the larger sizes to guarantee you have enough waterproofing tent spray to cover the entire tent because each can covers roughly 10-20 square feet. Using the Scotchgard Water Shield, you can feel a little safer outside during a rainstorm.


  1. You can buy different sizes
  2. Can use for cotton, nylon, and polyester
  3. Dries odorless


  1. 10-20 sq ft of use per can

5) Sof Sole Silicone Waterproofer Spray

The Sof Sole is a silicone formula with a 12 percent silicone content that may be used on a variety of outdoor materials such as polyester or nylon, but it works best on fabrics that are already waterproof, such as canopies or tents. The aerosol can makes it easier to apply because the spray is evenly distributed, but you may need more than one can to completely cover your tent.


  1. 12% silicone formula
  2. Good for polyester or nylon
  3. Easy to apply


  1. Can cause discoloration on wrong fabrics

6) NeverWet 11-Ounce Outdoor Fabric Spray

Although the NeverWet Outdoor Fabric Spray isn’t as well-known as some other brands of outdoor water protection, there’s no doubting that it’s a reliable tent waterproofing solution. Although using a trigger spray nozzle requires more effort than using an aerosol, the result is the same even coverage.


You can use it on polyester, cotton, and canvas, and each bottle covers at least 20 square feet, but you’ll probably need many bottles to cover your entire tent. The NeverWet will keep you dry outside if you’re seeking for a solid option to protect your tent from rainy weather.


  1. Can use for polyester, cotton, and canvas
  2. 20 sq ft of coverage



  1. Trigger spray nozzle

7) Better Boat Waterproofing Spray Fabric Protector

When sprayed on your tent, the Better Boat Waterproofing Spray is a very flexible solution that will provide complete protection from rainy weather. Any tent material should be able to work with the Better Boat because it works well on canvas, polyester, and nylon.


Although it is one of the larger bottles on this list, the pricing is comparable to some of the smaller bottles. The Better Boat brand is most known for protecting boat canvas and maritime materials, but it will keep you dry in any weather if put on your tent.


  1. Works well with canvas, polyester, and nylon
  2. Very versatile product
  3. Bigger sized bottle
  4. Great price for size


  1. Used more for boat canvas

8) Atsko Silicone Water-Guard

The Atsko Silicone Water-Guard is not as well-known as some of the other names in tent waterproofing materials, but it is just as effective as any of the other options on this list. It’s also one of the most affordable waterproofing options available.


The aerosol spray makes treating your tent incredibly simple without creating a mess or requiring a lot of hand pumping. The Atsko may be used on a variety of materials, including polyester, nylon, canvas, and others. It takes a while to dry, but once it does, you’ll be amazed at how effective it is when compared to other, more well-known brands.


  1. Very affordable
  2. Aerosol spray nozzle for easy application
  3. Can use on polyester, nylon, canvas and more


  1. Long time to dry
