Exterior paint averages $25-$40 a gallon, and a 3,000-square-foot home takes 15 or more gallons of paint, or $375-$600 just for the paint. However, really premium paint can cost $50-$100 a gallon, or $750-$1,500 for that large home. Doing it yourself also requires renting a pressure washer or sprayer for $50-$100 a day; extra-long ladders or scaffolding at $20-$75 daily; and a power sprayer for $50-$100 daily, plus masking tape, drop cloths and other supplies. However, it's possible to paint a large, two-story house for materials-only costs of $400-$600. Thornton House Painting

Once you have the approximate square footage that you’ll need to paint, remember that a gallon of paint generally covers between 250 and 400 square feet. You’ll need more if you’re painting a rough, porous material, or if you want to paint a dark house a much lighter color. Depending on your color choice, you may need a more expensive tinted primer to help with the color transition. Thornton House Painters
