    • Identify that the cord being repaired still works, then make sure both ends are unplugged and free to be worked on.

    • This method is best for when the insulation is damaged, but the wires are still intact as shown in this photo.

    • Measure out a piece of heat shrink to be at least 1/2 inch (12.7mm) longer than the damaged length of the cord. Then cut that piece to size.

    • For a better fit on the cord try to use the smallest size heat shrink possible.

    • Note that you can cut the heat shrink using scissors, a box cutter, or any kind of knife.

    • Be careful with sharp objects.

    • Slide cord through heat shrink to check the heat shrink covers all of the damaged area.

    • It is easiest to slide through at the smaller end of the cord.

    • Then, keep the heat shrink on the cord but away from the damaged area for the next steps.

    • Glue Gun Method: Prepare the hot glue gun by plugging it in and allowing it to fully heat up.

    • Glue Stick Method: Prepare the glue stick by cutting off small pieces to use.

    • Note that you can cut the glue stick using scissors, a box cutter, or any kind of knife.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

    • Be careful with sharp objects.

    • Glue Gun Cont. : Apply hot glue in excess over the damaged area and then slide the heat shrink over that area.

    • Glue Stick Cont. : Without applying any hot glue, slide the heath shrink over the damaged area of the cord.

    • Feel free to be generous with the glue. Most effective repair will occur when the heat shrink is near-full of glue for either option.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

    • Glue Gun Cont. : Completely fill the heat shrink with glue by placing the glue gun nozzle into the opening and fill the remaining space.

    • Glue Stick Cont. : Fill drop the small pieces of glue stick into the heat shrink. Firmly press the pieces in until they are tightly packed and the heat shrink is full.

    • Maintain even spacing between the walls of the heat shrink and the cord when applying glue.

    • Be careful with the glue gun, temperatures get hot enough to burn skin.

    • When enough glue has been added, apply heat from the lighter or other heat sources onto the heat shrink.

    • Be sure to apply heat in a back and forth motion. Alternative heating option can be hair dryer or heat gun.

    • Glue oozing out the sides is a good sign that you’ve applied enough.

    • Warning! Open Flame. Do not hold the heat source to one spot of the heat shrink or you will risk burning and damaging the cord.
