The brush is the one tool where quality is easy to feel. A good brush holds more paint, releases it smoothly and does not shed bristles into your finish. Brush shape matters too: angled brushes give control along edges, flat brushes cover broad trim surfaces.

Bristle type matters. In general, nylon or nylon-polyester blends are favored for water-based paint, while natural bristle is traditionally used with oil-based paint. Check the label on the brush and the paint can.

Angled brushes for cutting in

Who it is for: anyone painting walls next to ceilings, trim or corners.

An angled sash brush is the single most useful brush for wall painting.

Flat and general-purpose brushes

Foam brushes and small jobs

Disposable foam brushes leave a smooth finish and need no cleaning.

Edge tools

Who it is for: people who struggle to cut in freehand.

Edgers are no substitute for technique, but some find them helpful.

Brush care
