How Can I Make My Tent Waterproof?

Great question, isn't it. Your out in the woods or at the beach, and you think you have the best waterproof tent until the rains hit. You have leaking in the seams, water at the door, and rain through the zippers. Your waterproof tent is no longer living up to your expectations. Your entire family camping trip is on the line.

What can I do to Waterproof my tent? You can take many precautions before your camping trip to make the best waterproof tent. Apply Seam Sealer to all seam and zipper covers. Add beeswax to zipper to weatherproof them and make them more weather resistant. Also, Add a tarp above your waterproof tent to help your rainfly shed water. Finally, pay attention to your tent's location regarding low lying areas in your campsite so that a stream doesn't flood your tent.

As you can see, some of these items will help you improve your waterproof tent by considering the location and shelter offered to your waterproof tent. You can do other things by adding sealants and products to help your family tent shed water and keep the water from penetrating the interior of your tent.

Will Waterproofing the Tent Seam with Seam Sealants Keep Me Dry?

First, when you get that new Family Tent, don't just assume that it is the best waterproof tent. At a minimum, I always advise that you should apply a suitable quality seam sealant to all of the seams and zipper covers in this new tent.

These are usually the weakest location on your new waterproof tent that will leak. Direct rain will penetrate the stitching and eventually leak. Sometimes this issue is even due to heavy rains.

Applying seam sealer to all seams on your tent and rainfly will significantly improve your odds of staying dry, even in driving rains. Also, don't forget those zipper covers. They will also leak over time and cause dripping into the tent's interior. The majority of these products are liquid-based, that you can squirt on the seams and zipper covers.

These products can be found under many names, but familiar names include Coleman and Kenyon Seam Sealer. These products are readily available, and my advice is always to be sure to have a bottle handy on every camping trip. You never know when you will need this product to help keep you dry.

Should I Apply Sealant To My Entire Tent?

My gut response is "yes." First, I consider the addition of spray sealant extra protection. Yes, the rainfly is designed to keep the tent dry. However, even the rainfly can leak. Also, in driving rain and wind, the rain may penetrate the interior of your tent under the rainfly.

My advice is to take the time before your first camping trip with your new family tent and spray the tent and rainfly down thoroughly with a water repellent. There are many on the market. Names like Scotchgard, KIWI, and Gear Aid can provide you with quality water-repellant products to keep you dry.

Some of these products will be sprayed onto your tent and fly with an aerosol, while others use pump action. Regardless, they offer you the products to keep you dry. You need to apply these products to the rainfly, tent exterior, and even the floor of your tent. Also, pay special attention to the corners, as these areas can also be a weak spot in your new family tent.

After spraying the sealant to your tent and rainfly, you will need to let it dry as most of these are Polyurethane based waterproof sprays. Once completely dry, you are ready to roll your tent and head for the campsite.

Again, just as with the seam sealer, it's always a good idea to have a can of this waterproofing agent on hand. You never know what the weather will bring to your family vacation or family camping trip.

Other than Sealers, How else can I Keep My Tent Dry?

There are other precautions you can take to keep your tent interior dry in wet weather. First, I would suggest bringing two tarps with you on your family camping trip. You will place the first tarp under the tent so that the tent is not in contact with the wet ground. The Second tarp you will put above your rainfly to help keep water from overpowering your rainfly.

This simple application of the two tarps gives you the additional coverage and confidence to handle whatever the weather throws at you.

Location is another critical part of keeping your tent interior dry. It would help if you were sure that you are not setting up in a stream or at your campsite's low point.

This issue sounds simple, but I've seen a family set up a site in the low area and have the water from a hard rain flow through their children's tent in the middle of the night. Now, everything they own is soaked, and everyone is miserable.

If your entire campsite is low or if you have any question if water can penetrate your tent, you need to dig a trench around your tent. Yes, like days of old, you're creating a mote. This bank and ditch will help to divert the water around your tent, keeping your dry. This little extra effort will ensure that no matter the weather, the interior of your tent will not have a river running through it.
