For a cleaner look, opt for a caulk with a smooth finish rather than a textured one. Some brands also offer a “no-sag” formula, which is helpful when applying to vertical surfaces near the ceiling. Just make sure the caulk is rated for indoor use and has a long shelf life. If you’re painting over it later, choose a caulk that’s compatible with your paint type to avoid any adhesion issues. A little patience with the tool and a steady hand will give you a professional finish.
