The interior shell of your refrigerator is the component responsible for holding in the cold air that keeps your perishable items fresh. Damage to this shell causes the cool air to escape. When the temperature inside of the refrigerator rises, the unit kicks on and uses more electricity to cool the refrigerator more often. Repairing this damage immediately keeps your food cooler, your electric bill lower and extends the life of your appliance.

Unplug your refrigerator, remove all of the contents of the refrigerator and leave the door open to let the inner compartment warm to room temperature. Wipe out the refrigerator with a damp rag.

Mix the epoxy resin and the hardening agent as per the directions on the package. Apply the mixture to the damaged area of the refrigerator with your putty knife. Allow 24 hours for the epoxy to cure. Gently sand the area smooth with small, circular motions of the sandpaper.

Apply a second coat of epoxy thickly over the first patch. Press a piece of fibreglass cloth to the wet epoxy, and apply a top coat of the mixture over the cloth. Hold the top edge of the cloth, and rake the flat of your putty knife blade down the cloth to pull out air bubbles and excess epoxy. Allow 24 hours curing time, and sand the dried patch.

Spread a final coat of epoxy on the patch. Let the epoxy cure for 24 hours and sand smooth with small, circular strokes.

Wipe dust and debris out of the refrigerator with a damp rag. Plug in your refrigerator and let it cool completely before restocking it with perishables.
