Accidentally dropping the tank lid to your toilet and helplessly watching as it cracks in half is frustrating. Many toilets are made of porcelain, which is quite durable, but unfortunately not immune to chips and breaks. With small chips and cracks that are not located on a critical part of the toilet, repair is possible with glue. This can save substantial money, as replacing a toilet can be costly.
Clean the area between the breakage or crack with a solution of dish soap and water to remove any grease or dirt.
Spread a line of craft bond cement or super glue along one side of the crack or break.
Press the two sections of the toilet together and hold until the pieces bond. This should take several seconds.
Wipe away any excess glue that may have oozed from the crack.
Allow the glue adequate drying time based on the specific instructions on the package.
Fumes from the glue may be quite strong, so open your bathroom window or turn on a vent before using.
