Painting is estimated by the square yard, no deductions being made for openings such as doors and windows. Railings, grills, etc., are figured as if solid.

A gallon of paint will cover approximately 250 to 300 sq. ft. of old work and 350 ft. of new work. A painter should cover 150 sq. ft., 1st. coat, per hour, and 90 sq. ft., 2nd coat.

Cost factors may be easily determined from the above statements, and costs easily estimated for ordinary work.
