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. Broomfield House Painting

Interior and exterior paints need to stand up to entirely different menaces. Paint on the interior of your home will need to be cleaned or even scrubbed, while exterior paints need to be weather and sun-damage resistant. Both exterior and interior paints are a combination of pigment, solvent, resins, and additives. The solvent in paint keeps it liquid and spreadable until it dries on your wall or trim. Latex paint dries more quickly because its solvent is water, while the solvent in oil-based paints is mineral spirits, which takes more time to evaporate. Once the paint is applied, the solvent evaporates, and the resin allows the paint to adhere to the surface. Various additives in paint give it desirable characteristics, like moisture and scrub resistance. Home Painters Broomfield CO
Prep work should include removing all loose paint, either with a pressure washer or by scraping; removing any trace of mildew using bleach and water or a commercial solution, and sealing or covering dark stains; caulking all seams, corners and around windows or trim; applying epoxy filler to repair serious woodwork problems; covering dark stains; sanding all rough surfaces, and priming the bare wood with a bonding primer.

The lower end of this estimate is based on using a single colour with minimal prep and trim work. For a more difficult job that requires multiple colours, gloss architraves and a separate colour for the ceiling trim, a quote might be $30 or more per square metre. Expect to pay even more for special finishes like wallpapering, or to achieve crackle or sponged effects. House Painter Broomfield Colorado
