Latex caulk is usually used on the interior of your home to fill gaps between walls, ceilings, trim, windows, and doors because it adheres to wood and drywall well. Latex caulk is often referred to as “painters caulk” or “acrylic caulk” because it can be painted to match wherever you are using it. It guards against water penetration but is known to shrink and distort over time. Latex caulk is easy to use and cleans up well. In fact, it’s easier to remove when it needs to be replaced than other types of caulk.
