Nothing is more discouraging when you've finished painting than to peel tape off the woodwork and discover the paint bled through. To avoid the pain-in-the-neck chore of scraping off the paint, do a thorough job of adhering the tape before you start. "Apply tape over the wood, then run a putty knife over the top to press down the tape for a good seal," a painter with more than 16 years of experience says. "That'll stop any paint bleeds."
Lastly, chose a sheen to match the needs of the space. Flat finishes hide imperfections well and absorb light which can make the paint look darker. Eggshells and satins are tough enough to be used in family rooms, kids' rooms, and hallways but don’t hide surface imperfection well. Semi-Gloss and high-gloss finishes are primarily used for trim because they accentuate woodwork details and clean up easily.
A good paintbrush is key to a professional-looking finish. "A quality brush costs $15 to $25, but you'll discover that pros aren't as talented as you thought," says Doherty. "The equipment has a lot to do with their success." Most of our pros prefer natural-bristle brushes for oil-based paints, but they recommend synthetics for all-around use. When choosing a brush, pay attention to the bristles. Synthetic brushes are made of nylon or polyester, or a combination of the two. Poly bristles are stiffer, which makes them good for exterior or textured work, but for fine interior work, Doherty uses softer nylon brushes. Look also for tapered bristles, which can help you work to an edge, and flagged tips, which help spread the finish smoothly and evenly. Brushes are available in 1- to 4-inch widths. Most painters keep an arsenal on hand to match the job. "Use common sense," says Maceyunas. "A smaller brush gives you more control, but no one wants to paint a door with a 1-inch-wide brush." Doherty recommends starting with a 2- or 2-1/2-inch sash brush. The angled brush makes it easier to cut to a line and puts more bristles on the work than a square-tipped brush.
