@paintcrewnotes: The spread rate on the can is per coat. Bid it like one coat and you're short half the paint. Even paint-and-primer in one: Benjamin Moore's data sheet for Regal Select recommends two coats for full color. One coat dries to 1.3-1.5 mils, and the 400-450 sq ft per gallon is per coat. Bid math: sq ft x coats / spread rate = gallons. 12x12 room, 8 ft walls: 384 sq ft x 2 coats = 768 sq ft. 768 / 400-450 = 1.7-1.9, so 2 gallons, not 1 (walls only, before doors and windows). Bid one coat and that second gallon comes out of your margin. Do you bid by coats or by gallons?
