Tent Waterproofing
Yes, you can learn to do tent waterproofing yourself!
We all know the best way to get a truly waterproof tent is to buy one that's been coated with water resistant substances at the factory. However, there comes a time in the lifespan of every tent where the existing waterproofing fails. That's when you'll need to look into tent waterproofing methods to revive your old camping gear.
If you have a tent that needs waterproofing, it can be a good idea to dedicate one day a year to properly waterproofing it. There are lots of products on the market that'll do the trick, from solvent based ones to water based applications. Look for one that will do the job, and won't emit too many toxins. Let's take a look at the ins and outs of waterproofing your tent.
Do You Need To Waterproof?
Some tents may never need to be waterproofed. If you have a commercial nylon or other tent that's never shown signs of a leak, you probably shouldn't mess with a good thing. Likewise, many canvas tents (such as those used by historical reenactors) are made either from a pre-waterproofed fabric, or natural cotton canvas. This material is surprisingly waterproof without any treatment at all.
Conventional waterproofing can destroy the breathability of your canvas, which is one of the factors that balances out its greater weight. So, think twice before you get out the chemicals. They might be unnecessary, and they can even have an adverse effect on your tent.
Coat The Seams
Once you've decided that your tent needs waterproofing, there's one thing you'll need to pay attention to. All the tent designs out there have seams. They need attention with the sealer - don't miss any. You'll also probably have to waterproof the rain fly. In general, the easiest method of tent waterproofing that lets you be sure you've got it all is setting the tent up before you start. That way, you'll be sure of what you have and haven't coated, and the waterproofing will be more even.
Follow The Instructions
If the container tells you to use the product in a well ventilated area, do so. Apply tent waterproofing outside if possible, and wear a chemical respirator if you can't. Pay attention to the recommended distance instructions when using sprayable waterproofing, too. If you hold the can too close or too far away, you'll have trouble getting the right coating. Use gloves to protect your hands, and if heating the material is required for absorption, remember to apply it. Be careful, since some synthetic tents can melt or burn easily.
