Eggshell & satin finish

These images show the light reflecting properties of Eggshell or satin wall paint. (Satin and eggshell are virtually identical sheens.  They are both one full sheen above flat)

Why we recommend satin sheen on siding

Satin finish fights moisture while flat absorbs it.  Pigments are smaller and more tightly packed together in paints with the satin finish, making it harder for moisture to penetrate.
