How to Choose the Best Tent Waterproofing Spray

When selecting a tent waterproofing spray, there are several factors to consider to ensure you make the right choice for your specific camping needs. Here’s a comprehensive buying guide to help you navigate through the options:

Compatibility with Tent Material

Ensure that the waterproofing spray is compatible with the material of your tent. Tents are made from various fabrics such as nylon, polyester, or canvas, and different sprays may work better on specific materials. Check the product specifications or label to confirm compatibility.

Type of Coating

Consider the type of coating your tent has. Tents often come with different coatings like polyurethane (PU) or silicone. Some waterproofing sprays are designed to work better with certain coatings, so choose a product that complements the existing coating on your tent for optimal performance.

Ease of Application

Look for a tent waterproofing spray that is easy to apply. Most sprays come in a convenient spray bottle, but some may require additional steps like brushing or rubbing. Choose a product that fits your comfort level and the time you’re willing to invest in the application process.

Drying Time

Consider the drying time of the waterproofing spray. Some products require a longer drying period, which may not be ideal if you’re in a hurry. Others offer quick-drying solutions and allow you to apply the spray and pack your tent shortly after.

Longevity and Durability

Assess the longevity of the waterproofing effect. A high-quality spray should provide long-lasting protection against the elements. Check customer reviews and product specifications to gauge the durability of the spray in different weather conditions.

Odor and Environmental Impact

Consider any potential odor associated with the waterproofing spray. Some products may have a strong smell during application, so if you’re sensitive to odors, choose a spray with minimal or no scent. Additionally, opt for environmentally friendly options if that is a priority for you.

Packaging Size

Evaluate the size of the waterproofing spray container. Depending on the size of your tent and the frequency of use, you may need a larger or smaller quantity. Compact and travel-friendly options are convenient for backpackers and those with limited storage space.


Which tents can I waterproof?

Tents are usually made of polyester, nylon or cotton. All three materials are absorbent textile fabrics. This means they absorb water when it rains, and at the same time, offer the waterproofing agent enough hold on their surface. That is why every tent benefits from a waterproofing spray.

How environmentally friendly is tent waterproofing spray?

Today, waterproofing sprays are more environmentally friendly. They are CFC-free. Many manufacturers also do without the use of PFOA and PFOS. Nevertheless, some sprays contain solvents or substances that can accumulate in the human body. That’s why you should only use tent waterproofing sprays outdoors or in well-ventilated rooms and follow the instructions on the packaging.

Does waterproofing spray affect the breathability of my tent?

No, not at all! A breathable fabric loses this property when it gets wet. The water closes the small holes in the fabric. Waterproofing spray makes the fabric water-repellent, and the fabric stays dry. So breathability can even be improved.

How often do you have to waterproof a tent?

If you use your tent frequently and set it up several times a year, you should re-waterproof the tent about every 2 years. If it is rarely used, waterproofing every 3 years is sufficient.

How long does the waterproofing effect last?

The longevity of the waterproofing effect depends on factors such as weather conditions, frequency of use, and the quality of the spray. Generally, it’s recommended to reapply the spray every season or after several uses for optimal protection.

Can I use tent waterproofing spray on other outdoor gear?

Yes, many tent waterproofing sprays can be used on other outdoor gear, such as backpacks, boots, and jackets. Check the product label to confirm its suitability for various materials.


When selecting a tent waterproofing spray, it is essential to consider factors such as ease of application, coverage, durability, and compatibility with your specific tent material. Remember to follow the instructions provided by the manufacturer when applying any waterproofing spray to ensure optimal results.
