Things to Consider Before Buying Tent Waterproofing Spray

Waterproofing sprays are helpful for more than just protecting your tent from leaks. They shield the tent from sun damage, extend its life, and maintain its original quality. Therefore, you must purchase the best tent waterproofing spray that can provide you with the above features.

That is why we created this buying guide to highlight some of the most important factors to consider when purchasing tent waterproofing sprays.

Types of Waterproofing Sprays

When it comes to waterproof sprays, you only have three options. These include tent fabric, non-silicone vs. silicone sprays, and spray vs. aerosol bottles.

  • Tent Fabric

Canvas, Polyester, and Nylon are the three most popular fabric types used to make tents. As a result, silicone-based sprays can be used on these fabric forms because they are safe. If the tent is laminated or coated, you can even use a water-based spray.

  • Non-Silicone vs Silicone Sprays

Silicone-based sprays are best for waterproofing sinks and bathrooms to prevent water leakage. Moreover, the spray can penetrate entirely in the fabric so that it won’t peel away compared to acrylic or PU coating.

  • Spray vs Aerosol Bottles

Spray bottles have a trigger that allows you to spray manually. As a result, you have more control over the spray. The only disadvantage is that the solution could spread unevenly over the tent’s surface.

On the other hand, aerosol sprays allow for easy application with just one click of a button. They penetrate well into the fabric, but they may be harmful to the environment.

Environmental Impact

The water-based sprays are made with biodegradable ingredients which are gentle on fabrics as well as the environment.

No matter what waterproofing spray you use, it won’t remain on the tent’s surface for a lifetime. When chemicals meet the water sources, they gradually wash out the spray. So, if you want to reduce the environmental effects of chemical spills, water-based sprays are the way to go.

Water-based sprays make use of biodegradable additives, which are gentle on fabrics and the environment.

Breathability and Scent

When it’s rainy outside, no one likes to feel suffocated inside the tent. Waterproof sprays do not reduce the fabric’s breathability but rather maintain it. So make sure your waterproof spray doesn’t make you feel like you’re trapped inside a suffocating room with no windows.

In addition, the waterproof sprays on this list do not have a strong odor. You should make sure you purchase a waterproof tent that will be odorless as soon as it dries.





Frequently Asked Questions

1. How many times should you apply waterproofing spray on your tent?

During reapplication, you should reapply the waterproofing spray to the inner coating and seams as you deem necessary. You can pour water on the seam sealers to see if there is any leakage.

Rain guards tend to lose their effectiveness quickly, so keep an eye on the seams and reapply the spray if needed. In general, the spray can be used twice, once in the middle of summer and once in the spring.

2. How to apply waterproofing sprays on the tent?

Applying waterproof sprays to the tent is not as easy as it seems. To get an equal coat of spray all over the tent’s surface, you must follow the directions carefully. Here’s how to go about it:

  • Read the directions carefully to see whether the rain fly needs to be dry or damp to start the process.
  • Then coat the floor exterior and fly with an even and thin layer.
  • Next, let the coating sit for a while as directed on the spray bottle.
  • After that, you can wipe away any excess spray and let it dry for the time specified in the instructions.

3. Is it possible to make homemade waterproof spray?

Though making a waterproof spray for tents at home is not recommended, it is certainly possible. For this purpose, you need a consistent 1:1 solution of mineral spirits and silicone. However, if you make silicone-based spray at home, it won’t turn out gentle and will probably wash away in no time.

4. Do you need to waterproof your newly purchased tent?

The answer to this question depends on the quality and market price of the tent. Some of the high-quality tents are already waterproof, while the less expensive tents are not. If you don’t want leaks to ruin your camping trip, you’ll need to waterproof the less expensive tent.
