In the context of painting and the trade industry, a "brush" refers to a hand-held tool used to apply paint, varnish, stain, or other finishes to surfaces. It typically consists of a handle (made of wood or plastic), a ferrule (metal band that holds the bristles), and bristles (natural or synthetic fibers) that hold and spread the paint.
Brushes come in various shapes and sizes, such as flat, angled (cutting-in brush), or round, and are chosen based on the type of paint being used and the surface being painted. In professional painting, brushes are essential for detailed work, cutting in edges, and achieving a high-quality finish, especially in areas where rollers or spray equipment can't reach.
In summary, a brush is a fundamental tool in the painting trade, valued for its precision and control.
