Some wood floor sheens are shiny and some are not. Is one type of sheen better than the other?
It really is a matter of preference. If you choose to install a site-finished floor, you can choose any sheen that you like. Gloss finishes offer the most shine, and will reflect the most light. Semi-gloss finishes offer some shine, and will reflect some light. Satin or matte finishes offer the least shine, and will reflect the least light.
Generally speaking, the less sheen, the less you will notice small scratches and other wear that is normal with wood floors. If you choose to install a factory-finished floor, you will be limited to the sheen available for the material you select. All sheens will offer the same protection for your floor, so it truly is a matter of which look you like best.
