Nikwax is a great product brand, and it ticks off almost all of the boxes, which is why it’s our pick for best tent waterproofing spray. Nikwax products do double-duty as waterproofing products that protect from harmful UV rays.

Treat your tent with Nixwax, and it won’t fade over time, a massive bonus if you’re looking to save some money on your camping gear.

Another excellent quality of Nikwax is that it can be applied to both dry and wet fabrics with equal effectiveness. You could even use Nixwax during a rainstorm, and it would still be useful, although we recommend thinking ahead and putting it on before you hit the road with your tent.

Although Nikwax doesn’t have the versatility of some of the other waterproofing tent sprays, and should only be applied to synthetic fabrics, it’s still the best on the market for all of its other great qualities. What’s more, Nikwax products are relatively affordable, and you can tuck them right inside your camping bag.

Bottom line: Nikwax products are reliable options that you can use to waterproof your tent or protect it from the sun. They’re a legacy brand that campers have relied on for years, and they always deliver quality.

Part of having fun in the great outdoors is avoiding some of the less pleasant parts of nature, i.e. inclement weather. Torrential downpours can do more than put a damper on your fun; they can get all of your equipment wet and wind up, costing you tons of money in the long run. 

If you want to have a great time camping without worrying about the rain spoiling your trip, you need to learn how to waterproof a tent. You also need to find out which waterproofing sprays for tents are best for you. We’ve broken down the pros and cons of some of the most popular products on the market so you can choose the best waterproofing spray for tents to prevent your next camping trip being a soggy one.

How To Choose The Best Hydrophobic Spray for Your Tent

As with anything else, what makes a great waterproofing spray for tent fabrics is mostly up to a matter of personal preference, and what works for your lifestyle. Before you begin the process, ask yourself a few fundamental questions.

  • What sort of conditions will I be camping in?
  • How important is budget to me?
  • What kind of tent do I own?

There are some reasonably universal qualities that great waterproof sprays have, and many of the contenders on our list share these traits.

It Offers Sun Protection

A waterproofing spray will undoubtedly keep the rain out, but will it take care of the sun’s harmful rays as well? Over time, the sun can fade or weaken your tent, so many people opt for a fabric waterproofing spray that does double-duty as a water-repellant and sun-screen for your valuable tent. Many of the best sprays on the market offer UV protection, which protect the fabric of your tent, rain, or shine!

If you’re wondering how to waterproof a tent and protect it, rain or shine, simply clean it thoroughly and make sure all of the seams are completely secured. Then, apply the water proofing spray in a fluid, even coating paying particular attention to any zipper areas. If you use a waterproofing spray with sun protection, you can be assured that no parts will fade with time and that you’ll always be completely snug and dry during a thunderstorm.

Rapid Dry Time

If you’re in a hurry, or just impatient, you’ll want a product that has a very quick dry time. Many waterproofing sprays take several hours to fully dry, but there are a few products on the market that will allow you to spray them on and plunge your tent into the ocean within a matter of minutes.

While we seriously do not advise that you plunge your tent into the ocean under any circumstances, we are not exaggerating about the rapid dry time. There are a few products on the market that you can spray on and immediately reap the benefits of a few minutes later. If you are in a hurry or find yourself out camping with the sudden realization that you failed to waterproof your tent, these products could be a total godsend.

Budget

As with any other type of product, the budget is always top-of-mind. Some of the best spray on waterproofing options come in a whole range of different budgetary options, so you don’t need to break the bank in order to get a reliable product that will last you for years.

Identify your budget from the get-go and look for products that fall within your particular parameters. Once you’ve done this, you’ll feel much more comfortable selecting the product that works for you. A great pro-tip is to look for a smaller size of a high-quality product that will work remarkably for a single-use application. Sometimes smaller sizes are suitable for just one or two uses, but you can certainly maximize this by selecting a spray that does double-duty as a sun blocker and applying it to at the beginning of the season.

Versatility

Depending on what kind of shelter you have, you might want to find a spray that is versatile enough to be applied to all different types of products. This is especially true if your tent has several different fabrics on it. There are plenty of great products out there that work with synthetic and natural materials, and protect them both equally.

Selecting a versatile waterproofing tent spray is an excellent idea if you have a lot of different kinds of tents that you need to treat, or if you anticipate buying a new tent shortly. If you have room in your budget, it might be a good idea to purchase a waterproofing tent spray that goes on all different kinds of fabrics, as well as one that you will use on your primary shelter. These sprays rarely expire, so it’s a good investment.
