Mixing interior and exterior paint is not recommended. Each type of paint is formulated for specific conditions; interior paints are designed to be washable and resistant to scuffing, with additives for low odor and better air quality inside homes, while exterior paints contain additives for UV protection and resistance to weather conditions, such as rain and temperature fluctuations. Mixing them could result in poor performance, compromised durability, and a finish that is neither fully resistant to indoor wear and tear nor adequately protective against outdoor elements.
