1 gallon of paint will cover up to 400 sq. ft. (372 sq. meters) per U.S. gallon (3.78 Liters) on primed, smooth, nonporous surfaces. Coverage figures do not include material loss due to application. Some colors, drastic color changes, or porous surfaces may require more than one coat to achieve uniform finish.
