Seasoned campers already know the importance of waterproofing everything, but for the uninitiated, this is something that is, unfortunately, often forgotten.

Camping in rain and storm is not only uncomfortable (imagine being huddled in a flooded tent while you’re soaked to the bone), it can also be dangerous!

For example,

there’s the possibility of landslides or hypothermia should you find yourself stuck in a tent not meant to hold up against the elements.

We’ve already talked about the importance of waterproof tents–you can check out our article Here

But your preparations should not really stop from buying one.

In this article, we will talk about the importance of waterproofing your home away from home and give you a rundown of the best waterproofing spray for tents in the market.

What is waterproofing Tents and Why Should You Do It?

Best Waterproofing Spray For TentsContrary to what many think, waterproofing is something you should always do to your camping gear, whether they have a waterproof seal or not.

For starters, some tents are not 100 percent ready against water when you pull it out of the box, so it’s better if you quickly proof it before going out on a camp.

Moreover, waterproofing is also something you should routinely do on your gear since mother nature has a way of chipping away materials, regardless of how high-quality they are.

How often you should do this will depend on the number of times you use your tent, but just to be sure, it’s best if you test your gear before every trip by hosing it down on your backyard first.

How Do You Waterproof a Tent?

Waterproofing is something that can be easily done now thanks to handy waterproof tent sprays readily available in the market.

The whole process is generally divided into three basic steps:

Best Waterproofing Spray For Tents1. Sealing the seams

The seams are one of the most sensitive parts of your tent. Waterproof tents usually have these areas sealed to keep water from entering,

but these can weaken over time. To refresh the seal, you only need a seam sealer, some rubbing alcohol, and a rag.

Use the rag to dab rubbing alcohol on the spots that need attention to prep it before applying your seam sealer.

You can leave your tent in a sunny area to let it dry afterwards.

2. Re-applying the urethane coating

The urethane coating of your tent is one of the layers that makes it waterproof.

You’ll know that you need to refresh it once you notice the surface of your gear flaking and peeling.

To redo it, grab a slightly abrasive brush with alcohol and use it to gently scrub off the coating. Make sure that the surface is clean before re-applying your urethane sealant and leave it to dry.

When applying a fresh coat, give extra attention to the rainfly and floors since these are the surfaces that get the most contact with water.

Do note that the sealant of your choice will depend on the material of your tent. Fabric that has been treated with silicone will need a different kind than those sealed with polyurethane.

3. Refreshing the water repellant coating

This last step will keep your tent sealed and safe from rain. To refresh the durable water repellent coating of your tent, grab the best tent waterproofing spray that you have and spray the surface with it.

If there’s any excess coating, pat the surface dry using a damp cloth. Let it dry before packing away.

Some Tips to Prolong Your Waterproofing

Refreshing your tent’s protective layer is important, but it is just as essential to follow precautions that can extend its waterproofing.

Below are some helpful tips that will keep you from having to re-proof your tent every now and then.

1. Avoid sunlightBest Waterproofing Spray For Tents

Now, we know that this isn’t always possible, but it would be better if you can put up your tent in a spot away from direct sunlight whenever you can.

Besides from rain beating down on your tent’s waterproof layer, sunlight can also cause it to break down.

You can always go for a tent with a UV protection feature, but we suggest you also buy a waterproof spray that can add an extra layer of protection like some of the options in our list.

2. Store your tent properly

Did you know that the way to store your tent also affects the longevity of its waterproofing ?

Just like when you use it, the elements that it is exposed to when packed away can also chip away at its protective barrier.

When storing it, keep it away from a spot exposed to direct sunlight and do not leave it rolled up tightly for extended periods of time.

The reason for the latter is that doing so can cause dampness, which, in return, may lead to molds.

If you’re a little short on space, you can prime and apply a waterproof tent spray on it that can also protect it from mold buildups.

We have pretty good options in our list above.

3. Don’t machine wash your tent

Dryers and washing machines can affect the protective layer of your tent in many ways.

The continuous whirring can break down the polymers providing protection on the surface while heat can add damage to the fabric.

In addition, constant machine washing can also stretch your tent’s fabric.

This may make it more difficult for waterproof tent sprays to bond fibers together.

When washing your tent, it is suggested that you use cold water and non-detergent soap instead.

You can easily use a sponge to gently buff away and clean its surface without aggravating its waterproof layering.
