We have completed our 2nd job using the Harmony line (non VOC paint) of paints from Sherwin Williams. After 24 gallons we can say….WOW!  we used the flat for ceilings which I feel had too much sheen for a flat paint. We also used the eggshell for the walls.  We really put it to the test. After having a great feel for it in a bathroom, we cut in a room at the top and bottom of each wall, left for an hour, then painted the walls. When the paint dried, we had no flashing, no marks, no streaks, and no sign of where we started or ended. When the walls dried, the sheen was perfect, not too shiny as with most eggshells, it was more of a low luster look, with a great washability.

For homeowners, this would be a great one coat paint coverage.
