According to general guidelines, to paint a house with an area of 3000 square feet, you will generally need approximately 12 to 15 gallons or 45 to 57 liters of exterior paint and 4 gallons of paint for exterior molding for approximately two coats. For a larger house (around 3000 square feet), 25 to 30 gallons will be needed and 5 to 7 gallons for accented molding. A one-gallon can of paint will cover up to 400 square feet, which is enough to cover a small room, such as a bathroom. Anyone who has done their first interior painting project has been left in the paint aisle wondering how many cans they need to take home.
When you're very close to the finish line, you'll have a clearer idea of what a house painter should really do.
