Begin by cleaning the area thoroughly—remove old caulk, scrub with rubbing alcohol, and dry completely. Identify the exact seams, corners, and edges where moisture accumulates, as these are key areas needing attention. Ensure the surface is dry and free of debris before applying new caulk.

Squeeze a continuous, steady bead of caulk into the joint using the caulk gun, maintaining even pressure. Smooth it with your finger or a caulk smoothing tool for a clean finish. Hold the gun at a 45-degree angle and avoid over-pressurizing, which can squeeze air bubbles. Let the caulk cure for 24 hours without moisture exposure to ensure a strong, watertight seal.
