Once you decide on the perfect color, the next step is choosing your sheen. There are five to six standard finishes offered by most paint companies. The main differences between the sheens are luster (or shine) and washability.
Flat and matte paints are ideal for lower traffic areas as they are typically harder to clean. As the sheen increases, the easier the washability, since the “shinier” finishes contain higher levels of resin. Choosing the right sheen can help bring the room to life visually but is also a practical decision, since it can extend the life of your paint job.
