Satin finish offers a soft sheen between eggshell and semi-gloss, with better cleanability than the lower sheens. It holds up well in high-traffic interior spaces like hallways, living rooms, and kitchens, where walls get touched more often.
Its middle position makes satin the safe all-around choice when one finish has to cover a whole house. It cleans like a higher sheen but still forgives minor wall flaws, so it works in rooms flat finishes struggle with.
