  1. Disconnect the toilet from the water supply

    Turn off the water supply to your toilet before beginning. Switch off the shutoff valve located behind the toilet and then flush the toilet. This drains the remaining water from the toilet. Use your adjustable crescent wrench to disconnect the water supply line from the toilet tank.

  2. Dry the toilet parts off

    Use your towels and sponges to thoroughly dry off all of the individual pieces of the toilet. This includes water inside the tank. If you have a handheld hair dryer, you may also want to use this to make sure the toilet is completely dry. If there are any water droplets left over, the epoxy will not be as effective.

  3. Apply the epoxy

    Put your tube of epoxy inside of the caulking gun. Using a firm grip and applying pressure evenly, pull the trigger of the caulking gun and spread the epoxy onto all of the cracks. Once the epoxy is down, gently smooth it out over the cracks with your putty knife.

  4. Let the epoxy dry

    Wait for about 24 hours to give the epoxy time to dry. If you notice additional cracks during this time, apply epoxy to them as well.
