After you have your perfect product you will need to choose the perfect sheen. Sheen refers to the how shiny the finish will look. When deciding on sheen you will want to consider whether that area is high/low traffic and the condition of the wall.
The look of a flat or matte provides great depth of color that is also ideal for less-than-perfect surfaces. Flat is typically used for ceilings and low traffic areas.
The slight sheens of eggshell and satin reveal color with a softly polished glow with an easy-to-clean surface that's great for all high-traffic areas including living rooms and hallways. This is also a great product for colored ceilings to help reflect some light onto the color.
Semi-gloss is particularly durable and stands up well to repeated cleanings. It is often recommended for moldings and trim.
Today, many super-premium products, such as Benjamin Moore's Aura® paint, offer the same durability
and washability in all sheens, so the selection of the finish is more of a personal preference.
TIP: The higher the gloss of your wall paint, the more it will show imperfections. If you own an older
home in which the walls have been patched multiple times, or a home that has a lot of high walls with a
lot of natural light, you may want to use a flat or matte paint. This is also true for the exterior of your
home.
