Wash the pan in warm water and several drops of dish soap to clean off any food debris or stains. Dry the pan thoroughly with a clean rag.
Rub the crack with 120 grit sandpaper to sand down the crack and roughen the texture so it responds more effectively to the repair. Wipe away any loose sand from the pan with the rag once sanding is complete.
Mix an epoxy adhesive according to package instructions and apply it to the crack using a toothpick. This helps ensure the adhesive gets into the crack. Wipe away any excess once the crack is filled. Allow the repair 24 hours to dry.
