Learn how to fix if your tent's zipper doesn't lock together or it's getting stuck.
The zipper teeth don't lock together
If the teeth on your zipper are coming loose, you can try gently squeezing each side of the zipper's slider with pliers. This will help create more pressure when you zip it up.
The zipper keeps catching
If your zipper is getting stuck and not moving smoothly, try using some lubricant to make it glide better. Silicone Spray works best, but if you don't have it, you can also use soap, a candle, or a lead pencil. Just rub any of these along the zipper to make it easier to zip up.
