Just finished the base color on that side of the house a few hours ago. I hadn't measured before, but just measured and it's right at 1000 square feet of surface area. It required approximately 2.7 gallons of paint and a little more than a quart of primer for my spot-priming efforts. I may or may not do a second coat next spring. I put a second coat on a small area and it sure seemed like the second coat went much faster.

Anyone have any rough guess re: how much a pro painter would charge to paint 1000 square feet of standard lap siding? Tell me a big number so I feel good about doing this myself! :-)
