What are the differences in sheens and how do they wear differently?

Flat – This has a dull finish with low durability. It is not washable, and stains easily. Flat finish is primarily used for interior ceilings.
Matte – This has a dull finish and has medium to low durability. Matte finish can be used on interior walls and ceilings.
Eggshell – This has some sheen that makes it washable. This is the paint finish that we recommend most people use for interior walls.
Satin – This has a shinier appearance that gives it better protection from the elements, is durable and washable. This is the sheen we recommend for all of our exterior paint jobs.
Semi-gloss – This has a reflective appearance, is easy to clean, and is resistant to dirt and stains. This is recommended for interior trim, doors, bathroom and kitchen walls.
Gloss – This is very shiny and is highly durable. This can be used on cabinets and interior trim.
