How to Waterpoof a Tent

Prepare your camping gear for unpredictable weather, including rain. Camping tents often come waterproof from the store but may need constant re-applying of sealant to restore their ability to repel water, especially if used heavily. Waterproof your tent at home before venturing out into the wild to make sure you get the most protection from your shelter.

      Assemble your tent fully by following the manufacturer's instructions. Set it up on flat and even ground.

      Put on disposable gloves and apply seam sealant to all the seams on the outside and inside of your tent and rain fly. Apply a generous amount directly to the seams, including all corners of your tent.

      Spray the outside of your rain fly with the waterproof solution by applying even, overlapping strokes. Make sure to cover all surfaces of the rain fly.
