Interior paint is not formulated for exterior use and will not last long outside, typically fading, cracking, or peeling within a year or two. Exterior paints are specifically designed to withstand the elements, like UV light, rain, and temperature changes. For lasting results on the exterior of a house, it’s crucial to use exterior-grade paint. This can provide a durable finish that protects your home and looks great for 5 to 10 years depending on weather conditions and the quality of paint used.
