No home improvement project revives, beautifies, and protects a house as quickly, effectively, and affordably as exterior painting. A new coat of paint can completely transform the look of your home. And while painting a house can be a big job, it’s a project that can be completed in a week or two.
If you hire a professional painter, expect to pay from $3,000 to $10,000 or more, depending on the size and condition of your house, according to Home Advisor. You can save on labor by making it a do-it-yourself project, typically accounting for more than half of the cost. But know that painting your home will take some serious effort.
Whether you hire a professional or take on the work yourself, you’ll want this project done right so you don’t have to repeat it in a few years. Here are ten exterior house painting rules you should never break.
Pay for top-quality paint, primer, and caulking compound. Top-quality color lasts longer, flows more easily, and covers better than poor-quality paint. Buy paint with a lifetime warranty against defects in the finish. You get what you pay for with most house paint; the best ingredients are expensive. High-quality exterior paint typically costs $ 40.00 to $50.00 per gallon, and specialty paint can cost $100.00 per gallon or more. Be sure to choose 100% acrylic paint.
Top-performing exterior paint brands include Behr Premium Plus Ultra, Clark + Kensington, Sherwin-Williams Duration, and Benjamin Moore Aura. Flat finishes are preferred for siding and do an excellent job of hiding defects and irregularities. Satin and semi-gloss enamels are more durable and easier to wash.
For paint to adhere well, it must be applied to a clean, dry surface that is not flaking or peeling. Depending on the condition of the existing siding and trim, this often means considerable scraping and sanding before you can paint.
Begin by washing the surfaces. You can use a hose with a scrub brush, a detergent, or a pressure washer. If you use a pressure washer, be careful not to drive water deeply into the joints between the siding or erode the wood's surface with the high-pressure spray.
To remove loose, flaking paint, you’ll need a scraper. Then, a 5-inch disc power sander or a random-orbit sander will work well to draw more challenging paint and smooth the surface. Start with 60-grit sandpaper and follow up with 100-grit sandpaper.
The idea isn’t to remove all the paint—to remove loose paint and smooth the surface. Use a putty knife and wood filler to fill cracks and holes. Let the filler dry, and then sand these areas again. Brush off the dust, caulk the joints, and allow the caulk to dry before applying primer.
Although today’s house paint does not contain lead, paint applied before 1978 will likely contain lead. The U.S. Environmental Protection Agency warns that any home improvement work involving lead paint can create a cloud of lead dust or chips that can be hazardous to the health of children and adults. For lead testing and removal, the EPA recommends contacting a local lead-safe certified renovation contractor, which can be found on the EPA’s website.
Begin with a high-quality alkyd primer as your base coat if you’re painting over bare wood or metal, as specified on the paint label, to help keep the paint from bleeding. Some painters tint the primer toward the final paint color to minimize the need for two finish coats. Others prefer to tint the primer with a contrasting color, highlighting any spots the final coats haven’t completely covered. After the primer, apply the first finish coat. After it becomes tacky, apply a second topcoat.
Use a high-quality brush, roller, and, for some houses, an airless sprayer that can be rented at most home improvement centers or tool rental outlets. The easiest way to apply primer and paint to textured surfaces is to spray them with an airless sprayer, then back-roll by hand with a roller to ensure adhesion. If you have never used an airless sprayer, pay close attention to the directions, and gain a little experience by first painting a less-conspicuous side of the house. Work from a 5-gallon paint bucket, and use a paint strainer so the paint doesn’t clog the sprayer.
Don’t paint your house yourself unless you have the time, tools, skills, and stamina to do the work. Depending on the size and height of your home and the condition of the existing siding, preparing and painting a house yourself can be a tedious, demanding job.
Don’t paint on hot days, in the rain, or during windy weather. Ideal temperatures for painting are between 50 and 90 degrees Fahrenheit. Like the direct sun, hot weather causes the paint to dry too quickly. When possible, wait for the shade. Temperatures below 50º may prevent the color from adhering correctly to the surface. Dampness or dew can bubble surfaces.
Protect decks, shrubs, gardens, patios, and walkways from paint spills and splatters with drop cloths or plastic sheeting. This will save you from big cleanup problems later. If you use an airless paint sprayer, masking and covering are imperative – overspray can even coat your neighbors’ cars.
You can find lots of free information online, including videos by experts that break techniques down into steps. Work from the top down, starting with overhangs so fresh paint won’t drip on newly painted surfaces. Paint the siding, then, when dry, tape around the windows and doors and paint the trim. Remove the painter’s or masking tape to avoid residue as soon as you finish painting the frame. After the paint has dried, touch up areas where the dye hasn’t fully covered the surface.
Request detailed bids from three painting contractors and ask them for satisfied customers’ names and phone numbers. Call two or three of those customers or, if possible, visit their homes to inspect the craft. Networks like Angie’s, Home Advisor, and even Google and Yelp can help you find local professionals and see reviews from previous customers.
