Getting Started
    Painting the exterior of your house is a huge job. But the rewards are great too. With a minimum investment in tools and materials, you’ll save thousands of dollars, extend the life of your siding and increase the value of your home. Best of all, you’ll make it look like new again. While you may spend less than $1,000 on painting tools and materials, the same job done by a pro(专业人员) could easily cost $5,000 to $10,000 or more. The savings come at a cost, though. A good paint job requires countless hours of careful preparation. Plan to devote an entire summer to prepare and paint even a medium-size house.
    Completing a top-quality exterior paint job requires more than patience and perseverance. You’ll need a sharp eye, a steady hand and a bit of practice to paint straight lines. In addition, you’ll need the strength to move and set up tall ladders, and the confidence to work from them once they’re in place.
    Applying topcoats (the final coats of paint) doesn’t require much equipment beyond what you’ve already accumulated for scraping and priming. We recommend buying at least two top-quality synthetic-bristle brushes for applying the latex paint(乳胶漆): one brush ($15 to $20) for large areas and a brush ($9 to $12) for detail work.
    For applying paint to large areas of shingles(屋顶板), stucco(涂饰墙壁的灰泥) or brick, buy a roller(滚筒).
Paint Stores Can Help With Colors and Quantities
    Choosing exterior paint colors that complement(与……相配) the architectural details of your house and fit the character of your neighborhood is the first step to a great paint job. Check out bookstores and libraries for books on the subject. You’ll find brochures(小册子) at the paint store with collections of historic colors. Many paint stores have designers who can help you choose colors, or you could hire a designer or architect.
    Buy a quart(夸脱) of each color you’ve chosen and paint the entire color scheme on a small area of your house before committing to gallons(大量使用).
    If you don’t like the results, change the colors and try again.
    Next take rough measurements of your house, noting the type of surface. Count the doors and windows. With this information, paint store employees can help you calculate the amount of paint you’ll need.
    Buy the best paint you can afford. Good-quality paint is easier to apply, covers better and lasts longer. We recommend buying paint with a slight sheen, either satin or eggshell. It’s more fade resistant(不易退色) and easier to clean than flat paint.
Check the Weather
    Avoid painting in direct sunlight. The heat dries the paint too fast, making it nearly impossible to avoid blistering(起泡) and peeling(剥落).
    Avoid painting on very windy days. The wind causes the paint to dry too fast and can blow dirt into wet paint.
    Don’t apply latex paint when the temperature is below 50 degrees ℉ unless it’s formulated for cold-weather application. Read the label to be sure.
    Don’t paint when there’s a chance of rain.
Plan a Strategy for the Most Efficiency
    In general, work from the top down. Paint large areas first and details last. Where two colors meet, allow time for the first color to dry before returning to apply the second color. For example, paint the window sash(the movable part) early in the day and return to paint the frame around the sash.
Avoid These Common Problems
    Brush marks left at the beginning and end of a brush stroke are a common problem that’s easy to avoid. Start every brush stroke in an unfinished area, at an edge, or against door or window trim. Then brush toward the finished area and sweep the brush up and off the work in the same movement. If you stop the brush and then lift it off or set the brush down on a finished area to start the stroke, it will leave extra paint, which shows up as a brush mark or darker spot.
    Runs(油漆刷得过厚引起的挂流) are best avoided by constant vigilance(观察). Check back on your work as you go, paying special attention to inside comers and edges where paint is likely to build up and run. If the paint hasn’t begun to dry, brush out the run. Otherwise, allow the run to dry completely. Then sand it off with grit paper(砂纸)and touch up the spot with fresh paint.
Paint Like a Pro With These Techniques
    You can improve your painting skills by understanding the strategy pros use. They break down the painting process into two steps.
    The goal of the first step, called "laying on" the paint, is to get the paint onto the surface in the quickest, most efficient way possible. Don’t worry about smoothing it out yet. Use a brush, roller or sprayer(喷漆器) for this step and apply enough paint to cover the surface without creating runs. Cover an area just large enough to allow you to go back and smooth it before the paint starts to dry. Since heat, humidity and the type of paint you’re using all influence drying time, you’ll have to experiment as you start to paint to get a feel for how large an area you can safely cover before returning to smooth it out. The most common mistake beginning painters make is spending too much time and effort laying on the paint. A few quick strokes is all that’s needed. Then reload the brush and cover the next area.
    Once you’ve got a small area covered, you’re ready for step two, laying off the paint. First use your brush to spread the paint evenly over the surface and then finish up with long, continuous brush strokes. The goal is to completely cover(but not necessarily hide) the previous layer of paint with a smooth, even layer of paint. This step must be done immediately after the paint is laid on and before the paint starts to dry.
    You may be wondering how to tell if you’re applying enough paint. Unfortunately, there’s no exact formula. In general, you’ll have better success applying two thin coats than struggling to apply one thick coat of paint. Thin coats dry more thoroughly and don’t cause problems like runs, sags and paint buildup that are associated with heavy layers of paint. Your goal is to get enough paint on the surface to allow the brush to glide smoothly, but not leave so much that it forms runs.
