Selecting paint brushes and paint rollers requires an understanding of product features. Paint brushes differ in terms of bristle materials, handle materials, size, brush angle, and applications. Choices for bristle material include polyester, nylon and other synthetic products as well as natural materials such as goat hair, horse hair, and camel hair. Paint brush handles are usually made of wooden, metal, or plastic. Paint rollers are equipped with either a center-mounted handle or a side-mounted handle with threads for mounting on an extension pole. Roll covers are graded and may include a spatter shield. Typically, roller cover nap is specified in inches or fractions of inches. Paint rollers with smoother naps are used to apply paints to plaster, drywall, metal and other smooth surfaces. Refill rollers with rougher naps are used to apply flat paints to brick, concrete, stucco, and other textured surfaces. Paint trays are common accessories for paint brushes and paint rollers.

Art brushes for sign making, decorative, and other types of painting may be designed for use with acrylics, alkyds, fired glazes, oils, or watercolors.
