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.
According to Craftsman National Estimator, "High time difficulty factors for surface preparation and painting. Painting takes longer when heights exceed 8' above the floor. Productivity is lower when an application requires a roller pole or wand on a spray gun or when work is done from a ladder or scaffold. When painting above 8', apply the following factors: Thornton Home Painting
Rotten wood and siding material are nearly worthless to paint, as they will do nothing but to continue to deteriorate. You have a couple of options. Replace the siding or wood trim with new components, or in the case of small areas, use a wood hardener and match with an exterior filler product, such as a wood filler. Be sure to prep and sand either one prior to painting.
Wood is probably the most time-consuming when it comes to preparing it for paint. It has to be scraped and sanded until there isn’t a single chip or bit of loose paint in sight. Any wood siding or trim with wood rot will need to be replaced, and all cracks and holes need to be filled with epoxy filler. Brush painting and roll painting wood siding costs $43 per 100 sq. ft., and spray painting costs $34 per 100 sq. ft. Thornton House Painters
Lap marks are those ugly stripes caused by uneven layers of paint buildup. They occur when you roll over paint that’s already partly dry. (In warm, dry conditions, latex paint can begin to stiffen in less than a minute!) The key to avoiding lap marks when doing DIY wall painting is to maintain a “wet edge,” so each stroke of your roller overlaps the previous stroke before the paint can begin to dry.

As you remove the loose paint from your home by sanding and scraping, you'll likely notice individual areas that have become damaged. The damage might be from weather wear and tear, or possibly from animal or insect activity. Regardless of the cause, this is the perfect time to make repairs. This Family Handyman article on exterior paint prep reviews a number of the possible types of damage and how to address them. Once the repairs are done, you can clean off the surface. Sanding dust and debris will come off with a quick wipe down or air spray. But if part of the home is especially dirty — especially from road dirt kicked up by traffic — you may need to scrub the siding, either by hand or with a power washer. If you do opt for power washing, be careful not to spray upward. Always direct the sprayer so that the force of the washer moves in the same direction as rainfall. Your siding was designed to shed rainfall, not protect from water coming at it from below. See How to Pressure Wash a House for more details. Thornton Home Painting
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs. Thornton House Painting
In addition, paint features such as mold and mildew resistance are important cost factors. Many mold-inhibiting bathroom paints, for instance, cost substantially more than ordinary latex-acrylic paint—sometimes close to twice the cost. Also, paints that come with warranties from the manufacturer may be more expensive depending on the length of the warranty. (A two-year warranty is standard.) Thornton House Painting
Aside from the size and the material of your home, there are several factors that affect how much it costs to paint your home. If you paint the home yourself you’ll almost certainly spend less than you would if you hired professional painters. If you’re doing a cost comparison, remember to include the cost of painting equipment when you’re tallying the cost of a DIY paint job. You’ll need a ladder, brushes and buckets in addition to the paint itself. For an interior job, you’ll probably want tape and a drop cloth. Thornton House Painting
When home blogger Traci and husband Cy were tasked with the job of reviving a home exterior in Nashville, they knew the first order of business was to brighten up the brick. They began with the Sherwin-Williams color Balanced Beige (SW7037) and had a local Lowe's store shade it down to a darker, friendlier beige color. The turquoise door (Sherwin-Williams Reflecting Pool) in semi-gloss plays well with the beige paint and the dark natural wood shutters.
If less than half the old paint is left, however, it may be worth stripping it all off. Guertin gets rid of stubborn remnants using shrouded grinders (like the PaintShaver), infrared paint strippers (such as the Speedheater), or chemical strippers (like Multi-Strip), then smooths the wood with a course or two of sanding. When siding (or bank accounts) can't take the shock of a total strip job, Rich O'Neil, of Masterwork Painting in Bedford, Massachusetts, has successfully hidden rough, well-adhered paint under Peel Bond, a thick primer.
The real bulk of the work in exterior paint prep is surface prep. And make sure to avoid these missteps. The most difficult part of that prep is sanding and scraping. If you're working on an unpainted surface, you can give it a quick prep and move on. But most previously painted surfaces will need to have loose and flaking paint scraped off and the edges sanded flush. This is a tedious and tiring process, but it's an incredibly important part of the process. Painting over flaking paint will only result in new paint that flakes off, and skipping the sanding process will leave large, unsightly "divot" areas on your home. Power sanders can help speed the work, but be sure to use proper respiration and dust control. See this article on painting preparation for more tips on the critical steps of sanding and scraping.
