How to Re-caulk Your Bathroom

Re-caulking your bathroom is an essential maintenance task that enhances its appearance and prevents potential water damage. Over time, old caulk can become moldy, cracked, or start to peel away, leaving your bathroom vulnerable to moisture. Here’s a simple guide on effectively re-caulking your bathroom to ensure a watertight seal. 

STEP 1: Remove the old caulk

First, remove the old caulk around your bathtub, shower, sink, and toilet base. Use a caulk removal tool or a utility knife to cut through and peel away the old material while being careful not to scratch the surfaces. After removal, clean the area thoroughly with a mold-killing cleaner or a solution of bleach and water to remove any mold and residue. Allow the area to dry completely, as moisture can prevent new caulk from adhering properly. 

STEP 2: Tape the area

For a clean, professional finish, apply painter’s tape along the edges where you will apply the new caulk. This ensures straight lines and prevents the caulk from spreading onto adjacent surfaces.

STEP 3: Apply the new caulk

Choose a silicone-based caulk for bathrooms due to its mold-resistant and waterproof properties. Cut the tip of the caulk tube at a 45-degree angle. Using a caulking gun, apply the caulk smoothly and evenly along the seam. Smooth the caulk line with a caulking tool or your finger dipped in soapy water to press the caulk into the joint.

STEP 4: Remove the tape

Once the caulk is applied and smoothed, promptly remove the painter’s tape before the caulk starts to dry to ensure sharp lines.

STEP 5: Let the caulk dry

Follow the manufacturer’s instructions regarding drying time before using the shower or bath. Typically, it takes about 24 hours for the caulk to cure completely.
