How to Fix a Pinhole in a Coleman Air Mattress

Outdoor camping gear maker Coleman produces a series of self-inflating or pump-inflating airbeds and mattresses. While these air mattresses are built to be stout and puncture-resistant, small leaks or pinhole punctures do occur. To keep the sealed chambers working, the pinhole leak needs patching. Part of the problem with small leaks is finding the source. Once found, the patch process is a quick and straightforward task.

Things You'll Need

Instructions

    • 1

      Dip the sponge into the warm soapy water. Wipe over the surface of the Coleman air mattress, looking for air and soap bubbles coming off the surface, indicating the location of the pinhole leak.

    • 2

      Circle the pinhole leak with a marker. Dry off the mattress, and deflate it completely.

    • 3

      Cut out a small patch in the shape of a circle. Hold the ends of the cut piece under a flame, to melt the nylon strings -- keeping the patch free of frays.

      Apply a drop of the clean super-adhesive to the pinhole. Smear a light coat of the adhesive all over one side of the patch. Push the adhesive side of the patch onto the mattress, with the pinhole in the center of the patch.

      Hold a heat gun on the low setting -- or a hairdryer on the high setting -- over the patch for 30 to 45 seconds, to heat and melt the glue into the patch and mattress. Let the patch dry and cool for at least 1 hour.
