Like matte, eggshell is a lower-reflectivity sheen and can be used for similar applications while still providing the same elegant, smooth sheen. It’s easier to clean. Eggshell finishes have a slight gloss of about 10 to 25 percent, and are slightly more durable than flat finishes. However, they are not as durable as satin, semi-gloss or high-gloss paints.

• When Should You Use Eggshell Paint? Like a flat finish, eggshell is best utilized for areas with low traffic and not susceptible to dirt. In addition, if you have pets or children, cleaning is not as easy with an eggshell paint. If you plan on using eggshell, consider the texture of your walls. Because of the lower reflectivity, eggshell offers a better ability to hide imperfections on your walls. 
• Where Should You Use Eggshell Paint? Ideally, eggshell paint is also best suited for areas such as ceilings, bedrooms, dining rooms and living areas where there is not a lot of dirt build up or traffic. In addition, its medium-level durability provides added protection a flat finish does not. For areas such as walls, eggshell works best and is easier to clean. It would not be suited for a kitchen or bathroom space.
