Ensure good ventilation and protect surrounding areas with plastic sheeting.

Let the caulk dry per manufacturer instructions—usually 4–6 hours. Avoid water contact during this time. Once dry, trim excess caulk with a utility knife for a neat edge. Wipe away residue with a damp cloth. Allow full cure for 24–48 hours before fully using the shower. For optimal results, inspect monthly and re-caulk if needed to maintain a watertight seal.
