Yes, exterior latex paint often needs a primer to ensure better adhesion and durability. Primer helps to cover imperfections, provide a uniform surface, and block stains or previous colors from bleeding through. In some cases, paint-and-primer-in-one products are available, but using a separate primer generally offers the best results, especially on raw, patched, or high-contrast surfaces.
