Wow, I never knew this!

To execute this repair method, you'll need a few basic materials: a tube of silicone caulk (preferably in a color that matches your existing caulking), a caulk smoothing tool or a plastic spoon, a utility knife, rubbing alcohol, a clean cloth, and painter's tape. These items are readily available at most hardware stores and are essential for ensuring a smooth and long-lasting repair.

Begin by cleaning the cracked area with rubbing alcohol and a clean cloth to remove any dirt or soap residue. This ensures that the new caulk will adhere properly.

Next, use painter's tape to mask off the areas adjacent to the crack to create clean lines and prevent excess caulk from spreading.

Carefully apply a thin bead of silicone caulk over the crack, ensuring it fills the gap completely.

Use a caulk smoothing tool or the back of a plastic spoon to smooth the caulk and remove any excess.

Allow the caulk to cure for at least 24 hours before exposing it to water.

This method is effective because it addresses the problem directly without the need for complete removal of the old caulk. By applying a fresh layer of silicone caulk over the existing cracks, you create a new, watertight seal that prevents moisture from penetrating the surface. Silicone caulk is highly flexible and durable, making it ideal for areas that experience frequent temperature changes and moisture exposure. This approach not only saves time but also extends the life of your bathroom caulking.

When applying the new caulk, ensure that the bathroom is well-ventilated to allow the caulk to cure properly. It's also important to choose a high-quality silicone caulk to ensure a long-lasting repair. If the cracks are extensive or the old caulk is severely degraded, it may be necessary to remove the old caulk entirely before applying the new layer. Always follow the manufacturer's instructions on the caulk packaging for the best results.
