How can I effectively apply caulking around my tub to prevent water leakage and maintain a secure seal?

To effectively apply caulking around your tub, follow these steps:

1. Clean the area thoroughly to remove any old caulking and dirt.
2. Use a caulking gun to apply a continuous bead of caulk along the joint between the tub and the wall.
3. Smooth the caulk with a wet finger or caulk tool to create a neat finish.
4. Allow the caulk to dry completely before using the tub.
5. Regularly inspect and replace caulking as needed to maintain a secure seal and prevent water leakage.
