Ice chests and coolers are useful for keeping food and drinks cold, but when they are cracked they can leak and be ineffective. You can fix a cracked cooler, depending on where the crack is located—the inner lining or the exterior—and what type of material the cooler is made of. Fix a plastic cooler with plastic repair kits, which are available on the Internet or in home repair stores.
Things You'll Need
Plastic repair kit, such as Plast-aid
Stir stick or any other small stick
Wash hands and make sure that the cracked surface of the cooler is clean and dry.
Set the cooler on a flat surface with the crack face up so that the plastic repair mixture won't drip.
Put on a pair of gloves and mix the powder and liquid portions of the plastic repair kit according to the manufacturer's instructions.
Apply the plastic repair mixture to the crack. Use a stir stick or gloved finger to quickly fill in the crack before the mixture hardens.
Allow the mixture to fully cure, according the manufacturer's instructions.
For a quick, temporary fix, seal the crack with duct tape.
