Eggshell paint is a type of paint finish that has a slight sheen, resembling the surface of an eggshell. It is often used for interior walls and ceilings because it offers a balance between a matte and glossy finish. This makes it easier to clean than flat paint while still providing a soft, elegant look. The durability of eggshell paint makes it suitable for high-traffic areas, such as hallways and living rooms. It is also commonly used in home improvement projects due to its ability to hide imperfections on surfaces while reflecting light, enhancing the overall appearance of a room.
