Sanding not only feathers out chipped paint but also provides "tooth" for the next coat of paint. For glossy trim, use a sanding sponge rather than sandpaper. Sponges mold to the shape of the trim and last longer than paper. When applying latex over alkyd paint or when he is not sure of the original finish, Brian Doherty, a painter in Richmond, Virginia, follows the hand-sanding with liquid sandpaper to make sure the surface is completely deglossed to prevent incompatibility problems. "I've seen homes where latex was used on oil-painted trim, and the paint started to peel in less than a year," says Doherty.

Most pros don't bother cleaning brushes and rollers if they are going to use them the next day on the same job. "Latex paint dries slowly in cold temperatures," says Maceyunas. For two-day jobs, he wraps the rollers and brushes in plastic grocery bags and sticks them in the refrigerator. "Just allow the roller to return to room temperature before reusing it," he says. Roller covers are almost impossible to clean thoroughly. Most pros buy new covers for each job.
