Exterior painting is a process of applying paint or a protective coating to the outer surfaces of a building, such as walls, doors, windows, and trim. It serves multiple purposes, including enhancing the aesthetic appeal of the property, protecting the surfaces from weather elements like rain, sun, and wind, and increasing the durability and longevity of the materials. Exterior painting involves several steps, including surface preparation, such as cleaning and removing any loose paint or debris, applying primer to improve adhesion, and finally, applying the desired paint color or coating using brushes, rollers, or spray equipment. It requires careful attention to detail, proper choice of materials, and skilled application techniques to achieve a high-quality and long-lasting finish.
