Some brands offer an eggshell finish. It looks almost identical to a flat paint, but if you touch it, you can feel a slight sheen. It's the most popular paint surface, particularly for households with children or pets. Both can be very hard on paint surfaces. Eggshell is nearly as washable as a semigloss surface and is ideal for living rooms, dining rooms and bedrooms.
Some people use it in bathroom and kitchens.
You'll see them most often in bathrooms and kitchens. They're ideal for situations where you want a paint that cleans up easily but doesn't have the shininess of a glossy surface. Semigloss paints are durable and very scrubbable, so they're ideal for trim around windows and doors. Semigloss used to be a popular surface for kitchens. But lifestyle changes in recent decades have seen a decline in the greasy cooking that made this surface invaluable.
