Understand the Tent Fabrics

Tent fabrics and their coatings determine how waterproof and robust the tent is.


The natural fiber offers a number of advantages: Cotton is breathable, which ensures a pleasant tent climate. Well-waterproof cotton is almost waterproof and very UV-resistant. However, cotton is very heavy and will rot if stored damp.


Polyester tents are comparatively light and are very tear and abrasion resistant. Polyester does not rot, is reasonably resistant to UV radiation, and does not stretch when wet.


Nylon is even lighter than polyester and doesn’t rot either. It is tear and abrasion resistant. However, it is less resistant to UV rays and stretches when wet. That is why nylon tent has to be tightened from time to time when it rains.

PU coatings

A polyurethane coating is absolutely waterproof and offers a high water column. However, it becomes brittle over time due to UV radiation, so the water protection decreases if the tent is often left in the sun.

A PU coating is found on most polyester tents.

SI coatings

Silicone coatings are lighter than PU coatings. In addition significantly more resistant to UV radiation. The water column is not that high with SI-coated tents but is usually absolutely sufficient.

Nylon tents are often coated with silicone.


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, there are sprays that 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.


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.
