Fixing a Toilet Overflow That Leaks Through the Floor
- 1). Remove any old cracked or damaged caulk around the base of the toilet, if present. Apply a caulk remover to soften the caulk and then pry it up carefully with a putty knife, being careful not to damage the porcelain.
- 2). Pour a little bleach over a toothbrush and scrub the base of the toilet, where it meets the floor. Scrub all the way around the base, getting rid of any debris there.
- 3). Wet a sponge with bleach and wipe all around the base, taking up any dirt and debris that was loosened by the toothbrush.
- 4). Load your caulk tube into the caulk gun, back end first. Cut off the tip of the tube with your razor knife, making a diagonal cut with a hole of about ¼ inch across.
- 5). Push a long nail into the hole to break the seal inside. Squeeze the caulk gun trigger until the caulk rises to the tip. Press the release latch at the back of the gun to stop the caulk flow.
- 6). Hold the tip of the tube against the joint where the toilet base meets the floor. Hold the gun at about 45 degrees to the floor, tilted forward. Compress the trigger to push caulk out the tip.
- 7). Pull the gun along the base of the toilet as the caulk comes out, pressing the tip to the joint at the floor. Follow the shape of the base all the way around, sealing off the joint at the floor.
- 8). Wet your thumb and run it lightly around the whole caulk line, flattening the line against the base and the floor.
