Inspect the gap to ensure it’s clean and dry. For small gaps, use acrylic caulk which is flexible and paintable. Apply a continuous bead along the gap, then smooth it with a caulk finishing tool or your finger. For larger gaps, use backer rod (foam rope) to fill most of the space first, then cover with caulk. Allow the caulk to dry fully before painting if desired. This ensures a neat and finished look.
