Buyer’s Guide to Buying the Best Tent Waterproofing Spray

Picking between different tent waterproofing sprays can seem a bit difficult. At first glance there isn’t a whole lot to separate one product from another. Once you dig a little deeper though you’ll see that there are actually several key factors to keep in mind.

Price and Capacity

The good news with tent waterproofing sprays is that they aren’t that expensive. You can get a high-quality spray in a good sized bottle for between $10 to $20.

Depending on the size of your tent you’ll probably need about a 12 to 16 oz bottle to properly coat the rain cover.

Aerosol or Spray Bottles

You have two applicator options when picking out the best tent waterproofing spray, aerosol or hand spray bottles. Aerosol sprays come in metal cans, a lot like hair or bug spray.

They’re great for producing a really fine, consistent mist pattern and give you a very smooth application process. The problem comes with how they work. They contain both the waterproofing agent and a propellant.

This gives you a pressurized system that produces the fine aerosol mist. Some of these propellants are less than stellar for your health and the environment. If you’re looking for a more natural method you might consider a hand spray waterproofing agent.

These come in bottles a lot like your standard window cleaner. They have a small hand pump that produces the mist or directed stream. They require no propellent and so are additive free, but they don’t produce quite as consistent or fine a mist.

PFC and VOC free

When you’re considering any tent waterproofing spray you need to look at what chemicals it contains. Perfluorinated Compounds (PFCs) and Volatile Organic Compounds (VOCs) are the two most important to keep your eye out for.

These are chemicals that were once common in solvents and other industrial applications but that have now been discovered to have potentially harmful effects. VOCs in particular have been found to cause skin and eye irritation, headaches, nausea, and potentially long-term damage to the renal system and liver.

PFCs have been used for decades as a highly effective waterproofing agent. Unfortunately, the same properties that make them so useful for protecting against water and oil can lead to potentially nasty human effects.

Check the labeling of your tent waterproofing spray to be sure it doesn’t contain either of these substances.

Choosing the Correct Spray for Your Tent’s Fabric

Before you purchase a tent waterproofing spray make sure that you find out what type of material your tent is made of. The two most common are silicone-coated fabrics and polyurethane-coated fabrics.

These act as a physical barrier to prevent water from penetrating into the tent.

Most tents also have what’s known as a Durable Water Repellent (DWR) coating. This causes water to bead up on the outside layer of the tent or rain cover and prevent it from saturating the fabric.

Check your tents manual to find out what kind of coating it has and what you’ll need to refresh it.

UV Protection

Depending on where in the world you’re camping it can be a good idea to add UV protection alongside waterproofing. If you’re frequently out in the sun your bright and beautiful tent will start to fade over the years.

Depending on the type of material your tent is made from it can also weaken the structure. Choosing a tent waterproofing spray that also offers UV protection can help slow this process and protect your gear from wearing out prematurely.
