Tent Waterproof Sprays Buyer's Guide

Each waterproofing spray is made from a slightly different formula to make it effective. There are several characteristics of a waterproofing spray to consider before making a final purchase. 

Consider what kinds of material you want to use it on first, then think through these three aspects.

Here are 3 things to think about before you buy a tent waterproofing spray.

Silicone based

Many of the waterproofing sprays that are available on the market are manufactured with silicone, such as the Sof Sol Tent Waterproofer Spray. Silicone does a great job at thoroughly protecting from and repelling any water away from your tent fabric. It is also good at stopping oils and other staining liquids to have an impact.

Silicone-based waterproofing sprays often come with a percentage of silicone in them and the amount that is best depends on what you want to use. Silicone also can impact the color of certain fabrics, so you should always spot test with these sprays.

The downside to silicone-based products is that they are not biodegradable and can be quite damaging to the environment. That makes products like Grangers Tent + Gear Repel and Nikwax Tent & Gear SolarProof spray better if you want to protect the environment with your purchases.

Packaging type

There are only two primary types of packaging that a bottle of sprayable waterproofing spray comes in, aerosol and hand sprayers.

Capacity

The capacity of a spray bottle will mean that you either have enough for your project or need to buy more bottles. Consider that while you consider the price of each bottle and shipping. Some of the products, such as Gear Aid Tent Waterproofing Spray, only comes in small 5 ounce bottles.

Others come in options of over 100 ounces. Pick something that will get the job done and don’t go overboard in case it loses potency over time.

FAQ

How often do I need to apply the waterproofing layer?

Often, for the best effect, you should reapply the waterproofing layer at the beginning of every season. That is especially true if you use your material consistently. Apply it to your tent and the rest of the gear that should be waterproof, like your rain gear and backpack.

How many waterproof coats do I need?

If you are reapplying or supporting an older waterproof coating, you should only need one waterproof coat on top of it. If you are starting a new layer entire, then try to waterproof it at least twice.

Can I use the waterproofing spray on cloth tents?

Most waterproofing sprays are safe to use on a wide variety of fabric materials, not only nylon and polyester. Always do a spot test before applying the spray to the entire object since some formulas can affect the color and texture of the material.
