Eggshell paint has a slight shine, similar to a fresh egg’s shell. Eggshell paint does reflect some light, which means that it may also show some major wall imperfections. The particular manufacturer determines how washable it will be. All eggshell finishes are able to be washed, and some can be scrubbed. Traditionally, eggshell paint has been recommended for kitchens, bathrooms, laundry rooms, mud rooms and trim work.
Semi-gloss paint is a step up from eggshell and has a much more noticeable gloss finish. Semi-gloss lasts longer than eggshell and dries harder. On the down side, semi-gloss also reflects more of the wall’s surface imperfections than eggshell and will notably reflect light off of the wall.
If your kitchen experiences light to moderate use, eggshell would be a sufficient finish on the walls. Any homeowner that considers her kitchen more of a social hub and less of a cooking room can safely use eggshell and not worry about the life of the paint or how washable it is.
If you constantly use your kitchen for cooking meals and find yourself with plenty of messes on the walls and countertops, then semi-gloss is a great choice for your kitchen. Semi-gloss can be scrubbed as needed to remove any messes on the walls and will last longer under rough conditions than eggshell. If you have young children, semi-gloss is a good choice for easy cleanup of finger paint, crayons, baby food and anything else your little one can use to decorate the walls.
