Feathering is a term which means using a brush to paint around borders and corners. When used well this technique will produce a smooth transition between the brushed parts and the larger rolled surfaces. Some painters suggest that when you feather a ceiling, for instance, you should only cut in the border a few feet ahead of where you will roll. In other words, the best way to paint a ceiling is to have one person cut (feather) in and have a second person with a paint roller come up behind. This will insure that the paint dries smoothly.
Batteries will keep their charge longer if they’re kept cool. Warmer temperatures will shorten their life. Always recharge a battery right after it is used. Never store an uncharged battery and recharge unused batteries every two months.
