A satin finish is slightly shinier than an eggshell finish. Eggshell, low-lustre and satin paints are not as shiny as semi-gloss paints and are shinier than flat paints. They have warmer tones and lend an appearance of depth to the painted area.
Paints with higher sheen or gloss help brighten dark spaces, are easier to clean and resist dirt better than low-sheen paints. High sheen paints are good choices for bathrooms and children's rooms because they are durable. High sheen paints also draw attention to the surface and can highlight any flaws, so they may not be the best choice for an area with visible damage.
