Scotchgard Heavy Duty Water Shield

Scotchgard Heavy Duty Water Shield
Applications: outerwear, rain gear, umbrellas, patio furniture, outdoor gear, backpacks, luggage, canvas tarps, boat cover | Volume (fluid ounces): 21 fluid ounces | Price: $15.99

While all of the sprays mentioned here are excellent, they do have one major flaw:

Almost all of them focus only on waterproofing nylon and polyester tents – and can’t do anything for canvas tents.

Luckily, this spray made by Scotchgard is the answer to every canvas camper’s prayers.

On the plus side, it’s affordable, non-toxic, and can waterproof both nylon and canvas tents. It’s also completely safe to use on your outdoor patio furniture, boots, jackets, and a lot of other outdoor gear.

On the downside, Scotchgard claims that one canister can provide 20 square feet of water resistance on heavier fabrics. This means you could end up using two or more cans just to waterproof one tent.


  • Budget price makes it a great choice for frequent campers.
  • The coated fabric maintains its breathability, so there is no chance of inhaling dangerous chemicals.
  • Versatile – you can use it to waterproof your tent, yes, but also your outdoor furniture, backpacks, boots, and the rest of your camping gear.
  • Zero long-term smell – you might feel something for the first few hours, but the smell should be gone completely afterwards.


  • It might take two or more cans to completely waterproof your canvas tent, so be sure to buy enough.

Best for: campers who want to waterproof their canvas tents.

Choosing A Tent Waterproofing Spray: A Buying Guide

When it comes to choosing the best waterproofing spray, your choice really comes down to three important things:

  1. Aerosol vs spray bottles
  2. Silicone vs non-silicone sprays
  3. Type of tent fabric it’s meant for

Don’t worry if this feels too overwhelming – I’m going to break it down for you so you’ll know exactly which spray to choose and why.

Let’s dive in, shall we?

Aerosol Vs Spray Bottles

The first thing you need to decide is whether or not to use aerosol or spray bottles – both come with their pros and cons.

 Aerosol BottlesSpray Bottles
ApplicationClick and sprayPull the trigger and spray
ProsEasy to use, penetrates the fabric betterBetter control using the spray
ConsBad for the environment, must use several cansMight end up spraying your tent unevenly

Aerosol sprays are easy to apply – just click the button and spray away. They also penetrate the fabric a bit better. On the downside, they are not really great for the environment and you might end up using a lot more spray than you planned on.

Spray bottles work like a spritzer – you have to manually pull the trigger and the spray comes out. On the plus side, you get much better control over how much spray you’re using. On the downside, you might end up spraying your tent unevenly.

Silicone Vs Non-Silicone Based Sprays

I’ll make this simple – you want to use silicone-based sprays.

While waterproofing sprays tend to come in many different shapes and sizes, silicone is by far the best.

Silicone is used to seal bathtubs, sinks, and in other circumstances where no water is allowed to leak through. Compared to PU or acrylic coating, it completely penetrates the tent fabric and it can’t peel off.

All in all, when it comes to durability, safety, and waterproofness, you can’t go wrong by choosing silicone-based sprays.

Type Of Tent Fabric

Finally, we have the choice of tent fabrics.

Generally speaking, most tents on the market today are made out of three main fabric types:

  • Nylon
  • Polyester
  • Canvas

This is another reason you should use silicone-based spray since it’s completely safe to use on all the above-mentioned types.

If your tent is already coated or laminated, then you want to opt for a water-based spray – they won’t mess your tent up.

How to Waterproof Your Tent

You’ve got the waterproof spray, now what?

Well, waterproofing a tent is a pretty simple task.

It’s a simple 3-step process that goes like this:

  1. Wash your tent first
  2. Spray the tent
  3. Let it dry

Before you begin, you have to do some prep work.

Start by washing your tent to get dirt and grime off of it. If you place the spray on top of dirt and grime, it will lead to a bad seal and will not work correctly.

Once your tent is clean, set up the tent (if you haven’t already) and begin to spray the tent down. Make sure to spray every square foot that you can. Do so as evenly as possible and pay extra attention to waterproofing the seams. After a few minutes, wipe the excess off and now all you have to do is let it dry. Cure the tent for the length of time the instructions tell you before you pack it up or use it.

At this point, you may want to consider an additional layer (or sealant) to protect your seams, but that’s not always necessary.

Congratulations – your tent is now waterproof!

How to Make Your Waterproofing Last

Now that you’ve waterproofed your tent, you want to make sure it lasts. You don’t want to have to go through this whole process every time you want to use your shiny new waterproof tent. So, once you have let it dry and cure properly, make sure to store it properly.

Keep your tent in a cool, dark place, like a closet. Avoid leaving it out in direct sunlight. And if you go a long time without using it, make sure to check it regularly for mold.

To really care for your tent, never put it in the washing machine. Make sure you repair any damage to the waterproofing as soon as it happens before things get worse. Keep track of your tent’s condition, and your waterproofing will last.

It’s also a good idea to keep a spare can of waterproofing spray on hand at all times, so you won’t have anything to worry about!

Since I wrote this article, I’ve received a bunch of emails asking me about the specifics of the tent waterproofing.

A lot of the same questions pop up repeatedly, so I wanted to add this FAQ section to answer the most common ones.

Does a new tent even need to be waterproofed?

The short answer?

It depends.

While most tents that were made in the past few years are supposed to be waterproof right out of the gate, some cheaper ones are not.

When you combine that with the fact that these sprays are really cheap and easy to apply, you don’t really lose a lot by waterproofing your tent with them.

How often should you waterproof your tent?

Again, it all depends.

If you’re living in rainy parts of the country like PNW and you’re camping frequently (every month or so) you might need to do it on an annual basis.

On the other hand, if you’re a casual camper who camps several times per year in fair weather conditions, then you should be able to make your waterproofing last several years at least.

What’s the difference between seam sealing and waterproofing?

It’s quite simple:

You use tent waterproofing as a preventive measure before you go camping.

You use seam sealing to close a leak that already exists. A seam sealer is a glue-like substance that is absorbed into tent fabric and improves its water repellency.

Our Verdict

Make sure you’re never caught off guard in the rain again with the best tent waterproofing spray: Nikwax Tent & Gear Waterproofing Spray. It does a great job at waterproofing a variety of materials including tents, tarps, shoes, jackets, and much more.

Imagine never having to worry about getting wet while camping again. Sounds great to me!

Be proactive and use this waterproofing spray before you leave and keep an extra can on hand at all times for emergencies.
