How to Choose the Best Tent Waterproofing Spray

Below you will find our buying guide, which will help you narrow down our top picks to the one you will want to purchase. Look over each category because they will help you narrow down our products.


There are a few different types of ways that tent waterproof spray can be applied. The three major ones on the market are spray bottles, aerosol, and brush applicator waterproofer. You will need to decide which application type you prefer. In my reviews above, I have reviewed each type so take a closer look to see which one you think will look better.

Aerosol sprays are usually in a tin can and cover a surface very smoothly without a whole lot of waste like some spray bottles do. The mist from the spray bottle covers things like tents more evenly. The brush application method is another way to apply a waterproofer smoothly to a surface.

Silicone Spray

There are lots of different tent waterproof sprays, and the most common ones use a silicone spray to make products waterproof. You may have seen silicone on lots of products before. They work really well at protecting items from heats and well as making things waterproof. When used on tents, it makes a really nice water blocking barrier.

Different Tent Fabrics

Tents are made in all sorts of different types of fabrics. It is important to know which tent fabrics won’t well with the waterproofing spray.

Manmade fabrics such as nylons and silnylon almost have a plastic feel to it. These are man made materials that have been turned into fibers. The silnylon actually has silicone weaved into it, and when it is combined with the waterproofing spray, it makes a really strong barrier to water.

Polyester Is another material that is manmade, but it is more expensive and overall better quality than the nylon. Polyester has sort of a natural water repellant, so when it is combined with the waterproof spray, they work together quite nicely.


When dealing with chemical sprays, you typically think it will have a strong chemical smell. Some products certainly have a smell, but some of the ones I have reviewed above do not have an odor when used. Many people have sensitivities to smell, so having products that don’t smell bad or chemically is a great option. Take time looking through the reviews above to see which ones do not have a smell.


Price is another factor that determines all. You want a product that is going to be affordable as well as high quality. All of the products that are in our review are truly the best tent waterproofing sprays on the market with the best quality.

Decide on just how much you want to spend on a product and as well as how much of the waterproof spray you might need. There are some really inexpensive products on our list, as well as higher priced.

Tent Waterproofing Spray FAQ

Below you will find a few common questions and their answers.

Q: What is the best Waterproofing Spray for Tents?

A: There are so many great options in our best tent waterproof spray review, but If I had to pick one, I would pick the KIWI Water Repellent for Tents. This spray doesn’t have to be used just for tents; it can be used on other products too, such as boots, tarps, and other outdoor gear. This product comes as an aerosol spray to cover products more evenly and applies a silicone-based waterproofer.

Q: How Long Does Tent Waterproofing Spray Last?

A: Over time the waterproof spray will essentially wear off. I can’t give you an exact amount of time your waterproofing spray will last because this will all depend on how often you use the tent and how often it is exposed to the elements.

If you start to see your tent absorb some water or that it hasn’t been rolling off like it used to, then it might be time to reapply a coat to the tent. Even if you notice some tent’s flakiness, it might be time to get some more waterproof spray or reapply some more coats.

Q: How to Tell If Waterproofing Spray is Dry on Tent?

A: After you spray the tent, you want to let It dry for many hours before using it. To ensure the coat of waterproofing fully dries and cures, it will need at least four to six hours for a smaller tent and up to a day on a larger tent.

Q: How Often Should You Waterproof a Tent?

A: You should only have to apply the waterproof spray once or twice a year, but again, if you are using your tent and it is exposed to the elements more, you might have to reapply more waterproofing spray more than twice a year.

Q: Do Tents Leak When It Rains?

A: Yes, if you just have a regular tent, then they can leak and absorb rain when it gets wet. That is why it is very important to get a waterproof tent as well as use a tent waterproof spray that you can find above.

Q: How Long Does Tent Waterproofing Take to Dry?

A: After applying the spray or even the brushed-on version, you will need to let it lay out to dry for a little while as well as to cure. The curing process ensures that it has had enough time to fully seal and dry the silicone to prevent water from coming in. The curing process can take up to a day, but sometimes you can get away with just letting it dry between four and six hours.

Q: Do Waterproofing Spays Smell?

A: This is both a yes and no answer because some waterproofing products do have a chemically smell. Some products in our review above do not have a very strong odor smell and are more water based. That is perfect for people who have aversions to chemical smells. Make sure if you are using a waterproof spray with a smell that you let it dry and cure properly because then a lot of that smell goes away.


Many people don’t realize just how easy you can transform your tent into a waterproof one. Instead of buying a brand new waterproof tent, you can make it yourself at a fraction of the cost. I hope my review of the best tent waterproof spray helped you realize just how easy it is to do this. Please let us know which one you decided to go with.
