Tips for Keeping Your Tent Waterproof
It doesn’t matter how waterproof your tent is if you don’t pitch it correctly. If the fly touches the tent inner, it will eventually leak. Keeping the fly tight and taut is really important. As soon as you touch the fly from the inside, you break the surface tension. Which will allow the water molecules to soak through the tent.
On a similar note to pitching correctly, ventilation is key to staying dry inside your tent when it’s raining. When it is raining, condensation from your breath inside the tent can build up and start to drip.
Most of the time, your tent isn’t leaking. You just need more ventilation. Keep the vent open and make sure there is a gap between the mesh and the rain fly.
Dry Thoroughly Between Uses
Rinsing your tent and then letting it dry thoroughly before packing it away will prevent mildew and prolong the life the of the tent.
Difference Between Seam Sealing and Waterproofing Spray
Before you go with waterproof spray you need to be sure the leak is not coming from a puncture or seam. Punctures are easy to spot, but leaks along the seam of your tent might be harder to identify. Check the seams of your tent to see if your seam tape is beginning to peel.
How To Waterproof Your Tent
Before you begin waterproofing your tent, you will need to wash it to get all the dirt and grime off. Spraying waterproofing on top of dirt and grime will lead to a bad seal and it won’t work correctly.
Once your tent is clean and dry you may begin to spray the tent down. Make sure to spray every square foot that you can. Do so as evenly as possible and give extra attention to waterproofing the seams.
When you are done with the waterproofing spray, all you have to do is let it dry. Cure the tent for the length of time the instructions tell you before you pack it up or use it.
