Mixing interior and exterior paint for outdoor use is not recommended. Exterior paints are formulated to resist weathering, UV rays, and mildew, whereas interior paints lack these protective properties. Using interior paint outside can lead to premature fading, peeling, and other durability issues. For best results and longevity of your outdoor projects, use exterior paint as it's specifically designed to withstand the elements and protect surfaces exposed to outdoor conditions.
