In the plumbing industry, there is a longstanding debate about whether or not to caulk around a toilet base. Some plumbers say it’s not necessary, while others believe it can be beneficial and even required by codes.
If you're ever caught in this controversy, don't worry. This blog will provide all the necessary information to make an informed decision about caulking your toilet base.
Since bathrooms are prone to moisture, choosing a caulk that resists mildew is crucial. Hercules® Plumbers Caulk provides a flexible, durable seal that is mildew- and UV-resistant, making it ideal for bathroom use.
Color Options: Caulk comes in various colors, including clear, white, and even hues that match your toilet or floor. Clear caulk is a popular choice because it becomes nearly invisible once it cures, providing a clean look.
Before you start, you’ll need the caulk tube itself, a caulk gun (optional), silicone or siliconized acrylic-latex caulk, a utility knife, a damp cloth, and painter’s tape.
Clean the toilet base and the floor thoroughly to ensure the caulk adheres properly. Use the utility knife to remove any old caulk or debris. Apply painter’s tape around the base of the toilet to create clean lines and prevent excess caulk from spreading.
Cut the tip of the caulk tube at a 45-degree angle and load it into the caulk gun. Apply a steady bead of caulk around the base of the toilet, making sure to fill any gaps. Hold the caulk gun at a consistent angle and move it smoothly around the base for best results.
Use a damp cloth or your finger to smooth the caulk bead, ensuring it fills the gaps evenly. This process is known as tooling and helps create a watertight seal. Remove the painter’s tape immediately after tooling to avoid pulling up the caulk.
Follow the manufacturer's instructions for curing time, usually around 24 hours. To ensure the caulk sets properly, avoid using the toilet during this time.
Some plumbers recommend leaving a small gap at the back of the toilet to allow for potential leaks to escape. However, this approach is not foolproof, as water will most likely follow the path of least resistance. This is often down the toilet flange pipe rather than towards the back of the toilet. As a result, caulking the entire base is recommended as it provides a complete and reliable seal.
