Paint finishes refer to the final appearance and texture of a painted surface, which can significantly affect the overall look of a room or object. Common types of paint finishes include matte, eggshell, satin, semi-gloss, and gloss. Each finish has unique characteristics, such as sheen level and durability, making them suitable for different applications. Matte finishes have a flat appearance and are great for hiding imperfections, while gloss finishes are shiny and easy to clean, ideal for high-traffic areas. Choosing the right paint finish depends on the desired aesthetic and the specific needs of the surface being painted.
