Waterproofing a tent

A. Dear Soggy Sir, there could be a couple of different things going on that could make your tent so leaky.

First, if you fail to properly stake out your rainfly, it’ll just collect the rainwater and conveniently channel it inside your tent. So always keep the rainfly tight with the guy lines taut.

Another good idea would be to re-waterproof your fly. With wear and tear and time, all tents eventually lose their ability to repel water.

Luckily it’s easy — and cheap! — to rejuvenate it. Start with a tube of Seam Grip (about $7). Put your rainfly on top of your tent inside out and carefully reseal all the seams. While you’re at it, apply Seam Grip along the inside perimeter of your tent’s floor, too. Then flip your rainfly over, pitch it properly and spray it with a silicone waterproofer like McNett’s Thunder Shield (also about $7). Do all this and you’ll be Dry Dan from here on out.
