Things to Know Before You Buy a Tent Waterproofing Product

When provided with several options, choosing the best product with high performance can seem a little daunting. Hence it is necessary to prioritize your needs and choose the product accordingly. 

Below is a guide that can help you choose the products that can serve you best and prioritize your needs. 

Understanding the Fabric of Your Tent

Before purchasing waterproofing spray, it is necessary to start with what kind of tent you need it for. There are a variety of synthetic materials such as polyester and nylon and natural fabrics such as duck cloth tents and cotton available. 

Your choice of spray is greatly dependent on the material of tents. 

Synthetic materials

Nylon and Polyester are suitable materials due to their quick-drying properties and lightweight. However, they are not very breathable and can deteriorate with prolonged sun exposure and harsh climate. 


Fabrics such as cotton are usually coated with UV and water resistance, and they can vary from manufacturer to manufacturer. 

They are comparatively more breathable but cost a lot more than synthetic materials. Additionally, they are heavier and require more maintenance compared to synthetic materials.

There are many mixtures of the materials available in the market which bring their own set of pros and cons. If you are camping outside in the summer months, the waterproofing sprays with insulating properties would definitely be worth the money. It is necessary to know about the details of your tent before purchasing the waterproofing spray. 

Constituents of the Sprays

Checking the constituents of the formula is necessary and is often ignored when purchasing the waterproofing spray. In an outdoor industry, considering the environmentally friendly materials in sprays is a moral duty. 

Many waterproofing materials contain harmful substances like Fluorocarbon (PFC) and VOC, which are toxic for humans and the environment and take a long time to break down.

Spraying the tents with these materials would also expose you to the substance. 

Ideally, the best waterproofing spray would be the one without any toxic materials such as PFC and VOCs.

Sprays, Nozzle, or Tubes

When picking the sprays, considering this would be a good idea. A regular spray nozzle is easy to use and gives greater control. 

Aerosol, on the other hand, spreads the product evenly but can be damaging for the environment and expose you to harmful substances. 

The tube carries an adhesive and is usually preferred to fix seals and cracks in the tent. Seam sealing a tent is a necessary part of waterproofing. They act as a sealant between the outer and inner environments.

Your choice should be dependent on the purpose and ease of use. Usually, the reviews suggest that the nozzle works best for an outdoor space tent proofing. 

How to Waterproof Your Tent?

To never get caught off-guard by rain, it’s good to know how to waterproof your tent. Keeping a waterproofing spray handy is essential but knowing how to successfully waterproof is equally necessary.

First, make sure your tent is free of any dirt and grime.  

The best practice would be to go in an open space before waterproofing your tent, this makes sure you don’t expose yourself to harmful substances. Make sure there are minimal wind and sun exposure for efficiency. 

Spray generously to the exposed surfaces. Apply a second coat if necessary. Bear in mind, not to overspray. If you see it building and dripping, you must realize that you have over-sprayed. 

Let the spray dry completely for a few hours before packing. 

Storing your tent correctly is equally important. Make sure to store in a dark, dry space and dry it thoroughly between uses.

The Bottom Line

Although waterproofing is an excellent method of protection against rainy days, it should not be your only option. Sometimes, old worn off tents give up against nature, and updating your gear becomes a necessary option.

Using the best tent waterproofing spray can come in handy and is a way cheaper alternative. If you follow our guide and read through reviews thoroughly, you can find the best waterproof tent spray for your tent and gear. 

Just make sure to check the weather app, waterproof your tent before leaving, and make the best out of a rainy day.
