The difference between gloss, satin-wood and eggshell finish on metal and wood paints is the amount of light they reflect.
Paint with a gloss finish will reflect lots of light while an eggshell finish reflects low levels of light (as shiny as an egg shell). Satin paint sits in the middle and is ideal for doors and trims.
When it comes to choosing the finish on your interior wood or metal paint, consider how you want it to impact the lightness of your space. Interior wood paint is perfect for refreshing the wooden furniture or trim, while interior metal paint can be a great way to jazz up radiators, gates or other metal accessories.
