How To Waterproof A Tent — Tips To Keep You Dry In The Great Outdoors

There’s always a chance of rain when you’re camping outdoors. And you’ve probably experienced for yourself or heard of someone who’s camping trip got ruined when their tent failed to keep the water out. Most modern tents come with some waterproofing. Even so, the waterproofing will need to be renewed after a while. Learning how to waterproof a tent will work in your favor. It’s a simple skill, and greatly beneficial for campers. Let’s get started!

Precaution Is Better Than Cure — Caring For Your Tent

Before you go around mending the waterproofing of your tent, it’s worth knowing how to take care of your tent. Here are a few tips to make your tent’s waterproofing last longer.

No Machine Wash Or Detergents

Washing machines are torture for your tent, and dryers are worst. Conventional cloth cleaning supplies like bleach, detergent, spot removers, or pre-soak products should never be used on tents. These things will damage your tent’s waterproofing. They can also weaken the fabric and the seams, considerably reducing your tent’s expected lifespan.

A better way to clean your tent is to use a clean, damp cloth or sponge, You can use a non-detergent soap to scrub areas that are soiled.

Storing Your Tent

Ensure your tent is completely dry before you store it. The tent must be stored in a cool, dry place, away from direct sunlight. This will keep your tent mold-free. It’s also recommended not to keep your tent in their tight packaging for long periods.

Place A Tarp Under Your Tent When Setting It Up

A damaged floor will let moisture from the ground and plants into your tents. Waking up to water droplets inside your tent isn’t going to be as admirable as morning due. To protect the flooring of your tent, consider placing a tarp whenever you set it up. This protects the tent floor and can mitigate moisture in case the floor (eventually) develops a hole.

Avoid Setting Up Your Tent In The Sun

A lot of sun exposure isn’t good news for your tent and its waterproofing. Whenever possible, try to set up your tent in a shaded area. UV rays hasten up the degradation of your tent’s (or rainfly’s fabric), eventually causing leaks.

Use A Rainfly

A rainfly will protect your tent’s fabric from the rain and the sun. Most tents are sold with a rainfly, or you could buy one separately. In case you can’t find a suitable rainfly for your tent, buy a tarp in the right size. It’s better than leaving your tent unprotected!

How To Waterproof A Nylon Or Polyester Tent

Most tents these days are made from nylon or polyester. Both these materials are derived from plastic and are water-resistant to some degree, but they’re not unquestionably waterproof. Tents usually employ a coating to stay waterproof.

With time, this coating will degrade and require fixing to keep the tent waterproof. Here are some waterproofing methods to keep your tent going. Avoid using any homemade waterproofing spray for your tent, or taking the DIY route to sealants. More often than not, this approach causes more problems than it solves in waterproofing the tent.

Sealing A Tent’s Seams

If you notice a deterioration of sealant on the seams of your tent, it’s time to give the seams a boost. Seams are a very vulnerable area for water leaks, so keep an eye out for potential degradation.

If your tent has a seam tape that is coming loose, gently remove any peeling areas while keeping the intact sections undisturbed. Clean the area with rubbing alcohol and then apply the seam sealer. You can use something like a paintbrush to spread the sealer evenly.

Once done, let the sealer dry. It can take as much as 24 hours, so be patient and let it take its time. Also, be sure that you’re using the right seam sealer. Silicone-treated fabrics need a different sealer than polyurethane treated fabrics.

While you’re at it, apply some sealer at the points where the wall and floor of your tent meet. It’s a good precautionary measure and can be fairly useful.

Fixing A Leak On The Tent Wall By Refreshing/Repairing The Urethane Coating

In some cases, the tent wall (or floor) can develop leaks as well. A common symptom here is the appearance of flakes on the affected area. If you see flakes, it’s time to get to work.

Use rubbing alcohol and a sponge to wipe off the flakes and clean the area. Don’t be aggressive with scrubbing – you only want the flaked areas to be removed.

After this, apply a thin and even coating of sealant on the affected area. Once the process is done, let your tent dry for at least 24 hours.

Refreshing The Tent’s DWR For Effective Waterproofing

Another water repellent treatment is refreshing the DWR of your tent. A fresh rainfly beads water and sends it off to its merry path. Over time, the DWR (durable water repellency) may need some refreshing.

The best way to refresh the DWR is to first set up the tent. Once you’ve set up the tent, spray the DWR coating all over the tent or rainfly. After a few minutes, use a damp cloth to wipe off any excess coating. Let the spray dry for about 24 hours, and the DWR will be good as new!

Waterproofing A Canvas Tent

Cotton canvas is naturally waterproof and doesn’t require regular intervention from the user to stay that way. However, if you have a new canvas tent, or are using the tent after a long time, it’s better to let it go through “seasoning”.

For seasoning a canvas tent, simply set it up and let it absorb some water. The fabric and fibers in the tent will swell as they absorb water, and as they dry, they will seal the tent. It’s better not to take a hose to the tent, and let the process be at least comparable to natural soaking in the rain.

A simple way is to let your tent sit under sprinklers. A better way is to set it up and let your canvas tank soak in the rain. Check the weather forecast, and simply let your canvas tent soak up the rain for hours. It’s okay for the tent to stay in the rain for a couple of days. Once it dries, it will be waterproof and ready for your camping trip.
