Pick the size of the paint pad according to the size of the area you intend to cover. Use a 3- by 5-inch pad for large surfaces and window and door frames, for example. Use a 1- by 2-inch pad for narrow areas on windows or railings.
Select the paint pad material for the type of job. Foam pads cover flat areas well. Mohair pads paint tough surfaces such as stucco.
Pour the paint into a tray. The tray is more convenient and neater than painting directly from a can, especially since a pad holds less than a roller. With the tray, you can wipe off any excess before painting.
Paint with long strokes, all in the same direction, to produce a smooth appearance.
Feather the paint to disguise the line between strokes.
Clean washable pads with detergent and water as soon as possible after you have finished.
