How To Re Waterproof A Tent In The Best Possible Way

Posted On July 25, 2020

A lot of us must be planning to have a little outdoor getaway into the woods. But these days one can never trust the weather. The sun might be shining bright upon us with a clear sky at one minute, but before you know it, there could be heavy rainfall. So having your tent waterproofed is necessary to make sure that you’re prepared for any sudden changes in the weather such as rain.

Most of the tents these days are already covered with some kind of waterproofing agent. To make sure that your camping experience doesn’t get ruined due to rain . But, these waterproofing agents can wear out over a period of time which could cause the water-repellent coating to tear up. These tiny little leaks wouldn’t catch an eye until the water comes pouring through it during a rainstorm. The best way to make sure that your tent is waterproofed is to apply a water spray on it. If there are parts in your tent where the water pours through, then you should get it waterproofed. You can apply a water spray from either side (from inside or outside) of the tent and it will give you the same results. Lets check out the best way to waterproof a tent

There are three places a tent leaks- through the seams, fabric and Rain Fly. The following aspects needs to be taken care of to make sure that your tent stays waterproofed throughout your trip:

  • Seal the seams.
  • Refresh the DWR (Durable Water Repellent) coating.
  • Refresh the urethane coating.

Well you must be wondering about how to do all these things. So here is a detailed guide to make sure that you waterproof your tent properly before leaving for a camping adventure!


Most of the tents these days have seals already seamed. So if you have recently bought a tent you have nothing to worry about. Yet, the lamination cover on these seams will wear off over the period of time which will allow the water to pour in during the rain. Thus, it is necessary to make sure that the seams are sealed properly.

Seams are the points at which two pieces of fabric are stitched together. It is the easiest way for the water to enter inside the tent. Sealing the seams is rather an easy task and it shouldn’t take more than 25-30 minutes. It’s the part where you have to let the tent dry which consumes most of the time. One must let the tent dry for not less than 7 to 8 hours.

You’ll need the following things to seal the seams:

  • An old or tattered cloth

A sealant which is suitable for the fabric of your tent. (Different types of fabric need different types of sealant and it is necessary to choose the right type of sealant for your fabric. Make sure that your fabric doesn’t get damaged in the process. Most tents these days come with polyurethane-coated fabric. If you’re not sure about the type of the fabric that was used in the making of your tent, then you must contact your tent manufacturer before buying a sealant.)

  • Rubbing alcohol

A small paintbrush (Usually all the sealants these days come with an applicator but if it’s missing, you can use a paintbrush to apply it.

  • Safety gloves

Once you gather everything you need, you should find a nice spot where you can easily let the tent dry for hours. Waterproofing the tent indoors is better but it can only be done if you have enough space. But, waterproofing it outside is also not an issue. You just have to make sure that the tent can be left out to dry for hours once the process is completed.

Just follow these simple steps:

  • Set up your tent in a room with enough lights or a dry, sunny spot outside which provides enough light to examine all the seams properly.
  • If any of the seams are tearing apart, then you must apply a tape on the reverse side to hold the seams together. You cannot seal the seams until you apply the tape on the reverse side of the torn part or the seams. If the tear is severe, apply a second layer of sealant to make it durable.
  • The seams will be sealed in the inner part of the tent body and on the underside of the fly. So, to get easier access to the seams, turn the fly sheet inside out.
  • Now if there are any seal bits that are peeling off, remove them.
  • Gently clean the seams by applying rubbing alcohol and a tattered cloth.
  • Let the seams dry off properly before applying the sealant.
  • Once the seams are cleaned and dried properly, apply the sealant using an applicator or the paintbrush.
