You must use this product in a well-ventilated area – the smell can pack quite a punch and you don’t want to inhale the fumes. The smell completely dissipates after drying.

best waterproofing spray for shoes

This silicone-based water guard dries in 24 hours and is fully cured in 72 hours. Available for purchase in a single- or two-pack 10.5-ounce canister.

The Verdict

Atsko’s water-guard spray restores your belongings to factory waterproofing. This spray is unbeatable for shoes – leather, canvas, and even suede! Your shoes will be protected from water while the material is still breathable.

One of the best features – your shoes will even be protected in the snow!

The spray works for other items, but you will really need to be aware of the lingering odor.

In Summary...

Atsko created a product that will keep your feet dry and shoes protected in all sorts of weather and environments. If you like dry socks, you will be satisfied with this water repellent.

How to Waterproof Boots & Shoes

Waterproofing shoes with a spray is actually quite easy and will save you a lot of wet socks when you're out hiking in the rain. This process may be different though depending on what kind of boots you have.

Step 1: Cleaning 

First, make sure that your boots are completely clean. This means removing the laces and using a brush to get rid of any dirt or grime. You can even soak the boots to remove any dirt caked on the bottom. Just let them dry before you start your waterproofing.

Fabric Boots

If you have fabric, make sure that it’s completely clean first. You can spray fabric boots while they’re wet or dry, but many people like to make sure they’re dry and leave them out overnight to dry. This takes longer, but you’ll be able to see if you got all the spots.

Leather Boots

Start with clean leather shoes and use a hairdryer to heat the boots up. This lets the boots absorb the wax better. All you do from there is rub the wax over the boots, let it dry for about an hour, and get moving.

This waterproofing spray comes in a 10.5, 16.9, or 33.8 fluid ounce size bottle. It comes in a trigger spray.

The Verdict

Nikwax TX Direct is ideal for outdoor clothing. It is especially useful for restoring waterproof properties to older or improperly cared for clothing and bags. If you want extra protection, put on some gloves and rub more product directly onto high use areas.

Like the other products, use this in a well-ventilated area. This product produces bigger droplets due to the trigger spray bottle, so be extra careful when applying it around pets and children too.

In Summary...

This is the quintessential waterproof spray for all your clothing needs. A classic choice for hiking, fishing, and other outdoor adventures or even spraying a college student's backpack for those rainy days around campus.

Revivex vs. Nikwax

The best eco-friendly water-based brands when it comes to waterproofing spray are definitely Nikwax and Revivex. Nikwax provides a solid waterproof coating while remaining breathable, although you should only use this spray on tents, backpacks, and camera bags.

This makes it perfect for when you’re camping and want to keep your items safe, especially since this spray is meant to be “solarproof” too. This means that you’ll be protected both from water and from UV rays that can damage your fabrics. Just apply the spray using the applicator and let the fabric dry.

If you want to waterproof more types of items, you may want to try Revivex instead. There’s even more breathability with Revivex that allows you to use it on a wider range of applications. All you have to do is spray the aerosol can for easy application and a good coating. Make sure that your fabric is flat and let it dry properly, whether you’re using the spray on a tent or a waterproof shell. There’s no odd smell to this spray either, unlike Nikwax.

No matter which spray you use though, since both of them are water-based, so as long as the fabric is clean, these sprays can be applied whether the fabric is dry or wet.

best all round waterproofing spray


Star Brite’s Waterproofing Spray is available in a 22oz trigger bottle or a hefty 128oz free-pouring bottle. The 22oz bottle is good for 80sq feet of coverage and the gallon bottle should manage well over 450sq feet.

The Verdict

Your tent needs special protection since it is open to all the elements. This is the best choice since it is will protect your tent in sunny, rainy, or snowy weather.

The trigger spray bottle can be tiresome to use if you have a large tent. You can wear gloves and apply it by hand or purchase the bigger size bottle and use a continuous one-hand pressure sprayer.

In Summary...

If your tent is often exposed to the weather, this is the best choice to protect it and you from the elements!

​Is polyester waterproof?

Well, nothing is completely waterproof. But polyester is actually water-resistant, which is quite different than waterproof.

Basically, polyester is able to protect you from most everyday situations, like if you step out in the rain or the snow. It won’t remain dry or protect you from water if it’s underwater for a prolonged period of time though.

This because any polyester item isn’t necessarily woven together to be waterproof, even if the individual threads are. Polyester clothing also has zippers and openings to let the water in. But polyester is water resistant, meaning that it’s extremely dense and it will take much more time for any water to seep in. Polyester may not be a natural waterproof fabric, but the waterproof resistance is still perfect for camping or for a drizzle.

How to waterproof fabric

You have a waterproof spray in your hands and want to waterproof your fabric. So… what do you do? Well, instead of waiting for your fabric to dry or trying desperately to keep it out of the rain, try waterproofing your fabric first.

It should only take a few minutes to apply, and a few more hours for the fabric to dry fully. When you’re done, the water should roll right off rather than soaking in.

Using a waterproofing spray

When you’re using a spray, first start by laying out your fabric over a piece of cardboard. Lightly spray the surface of the fabric while holding the can about 6 inches away. Go over the entire piece of fabric without applying it too heavily. So, the fabric should not be completely saturated with spray.

Usually, you’ll want to put on a second coat after you let the fabric dry for about four hours. After that dries, then you’ll be good to go and ready to test it out.

With Wax

You also have the option to use wax to seal the waterproofing quality into your fabric. This is a more labor-intensive option, but if you have the items, you can use this method instead. You’ll first need to melt the paraffin wax using a double boiler while your fabric goes into the dryer to warm it up. This makes applying the wax easier.

From there, apply the hot wax to the fabric with a small paintbrush, working over the fabric one section at a time. Dry the wax by aiming a hair dryer on high at the fabric, letting the wax melt into the fabric.

How to waterproof a backpack

There’s nothing worse than hiking in the rain and realizing that your backpack and everything inside it is now wet. Use your waterproofing spray to protect it.

Alternatively, a rain cover is always an option. They won’t keep all the water out, and it will be hard to get your items, but they’ll provide extra protection.

Leather Waterproofing

Leather is different than other materials. It’s very porous, so it won’t ever be completely waterproof, but you can protect it from water by waterproofing it yourself. Apply a spray like normal, or use the waxing method we talked about for leather boots.
