Most painting jobs can be done with a few quality tools. Purchase two or three premium brushes, a sturdy paint pan that can be attached to a stepladder, a supply of disposable pan liners, and a variety of roller covers. With proper care, high-quality brushes will last for years.
Brushes made of hog or ox bristles should be used only with alkyd-base paints. All-purpose brushes blend polyester, nylon, and sometimes animal bristles. Choose a straight-edged 3" wall brush, a 2" straight-edged trim brush, and a tapered sash brush.
A quality brush (left), has a shaped hardwood handle and a sturdy reinforced ferrule made of noncorrosive metal. Multiple spacer plugs separate the bristles. A quality brush has flagged (split) bristles and a chiseled end for precise edging. A cheaper brush (right) will have a blunt end, unflagged bristles, and a cardboard spacer plug that may soften when wet.
A 3" straight-edged brush (top) is a good choice for cutting paint lines at ceilings and in corners. For painting woodwork, a 2" trim brush (middle) works well. Choose brushes with chiseled tips for painting in corners. A tapered sash brush (bottom) can help when painting corners on window sashes.
