How to Fix a Tent's Rain Fly

The rain fly is the primary barrier between the camper and the elements. The main tent typically includes breathable fabrics that are not effective against moisture and weak points in the rain fly allow water to enter the sleeping area. Making repairs to the rain fly is accomplished by patching holes and reinforcing weak points in the fabric. Making the repairs is simple but may be time consuming if the damage is extensive. Tears in the fabric must be repaired as soon as possible to avoid making the tear an excessively large hole.

Instructions

  1. Seam Sealing

    • 1

      Remove the entire tent from the storage bag and set it up outside. Choose a sunny day to encourage quick curing of the seam sealant.

    • 2

      Locate the seams on the outside of the rain fly. Fill a plastic syringe with seam sealant and apply a thin layer of the sealant to the seams. Cover the entire seam to prevent leaks and repair weak points. Leave the tent in the sun until the seam sealer is smooth and hardened.

    • 3

      Remove the rain fly from the tent and turn it inside-out. Place the fly on the tent with the inside exposed to the sun. Apply a thin layer of seam sealant to the inside of the seams and leave the rain fly in the sun until it is cured.

    Patching Holes

    • 4

      Lay the rain fly flat on the ground with the inside facing the sky. Examine the fabric for tears and circle the areas with a black pen. Cut a waterproof nylon patch to twice the diameter of each torn area.

    • 5

      Align the fabric to match the torn area into the original shape. Cover the bottom of the patch with seam sealer and place the patch on the torn area.

    • 6

      Place a piece of paper on the patch and place a heavy book on the top of the paper. The pressure ensures the seam sealant spreads and cures without adjustments. Leave the book on the patch for six hours before inspection.

    • 7

      Remove the book and peel the paper off the patch. Check to ensure the seam sealant has cured before packing the rain fly into the tent bag.
