The only downside of this spray is that it only works on nylon tents, so be sure to check your tent material before you buy it.
Kiwi Camp Dry is a silicone-based waterproofing spray that bonds the fabric of your tent together to form a tough waterproof layer. It can be used on all your outdoor gear (bar performance fabrics), so if your tent is polyester, this spray will be fine, but it works best on nylon.

Applying it is easy, just spray it on your tent. You will have to do two coats for it to be 100% effective and the drying smell isn’t very nice, it smells a bit like paint. The good news is that once dry it is odor-free, so as long as you dry it out, you’ll be able to camp without any toxic smells.

Once applied it retains breathability and is pretty long-lasting as far as waterproofing sprays go. It does contain some nasty petroleum substances, so by using it you’re not helping the environment very much.
The Nikwax Softshell Proof Waterproofing Spay is one of the best choices for versatility and the environment. It contains no harmful substances, is odor-free and it’s biodegradable too, so as it washes off your tent, it’s not harming the ground it lands on.
Applying it should be easy as it’s a spray-on, but the nozzle is a little tricky and does need to getting used to. Make sure you work it out before applying it so you don’t waste any.

Sof Sole Silicone Waterproofer Spray is one of the most affordable waterproofing sprays in the review and it works on any material that isn’t breathable.
In case you’re wondering, your rainfly, whether it’s polyester or nylon is not breathable in order to keep the rain out, but your inner tent is breathable, so do not apply it there.
The spray contains a 12% silicone formula that creates a durable and long-lasting waterproof bond. Not only does it repel water, but also oils and dirt to keep your rainfly clean.
Applying it is easy, just spray away but you will need to do 2 coats to ensure it’s effective. While applying, you’ll want to cover your mouth and nose so as not to breathe in the intense odors, plus we’d recommend drying it outside and make sure the odor has gone before your next camping trip.
It doesn’t retain breathability, so make sure you don’t use it on any performance gear like Gore-Tex or it will ruin its valuable properties.
Atsko Sno-Seal Water-Guard is simply one of the best tent waterproofing sprays around. It’s so versatile that you can pretty much spray it on anything from Gore-Tex to nylon, polyester, and canvas.

It comes as a spray but not an aerosol, so you can avoid being fogged while applying it. The application is easy, just be sure to wear a protective face coating.
Once applied and dried fully, which takes 6-12 hours, it provides an excellent water-repellent coating that also repels dirt, oils, fungus, and protects from UV damage too.
While it is powerful, it’s not good for you or the planet, so bear that in mind. It is also pretty expensive compared to the others.
