Paint brushes are the most common method for applying paint and other liquids or coatings to a surface.
General types of paint brushes;
- Cutting in brushes are designed to cut straight lines in smaller areas such as window frames and door frames. Cutting in paint brushes are usually assembled with more taper in the bristle to aid cutting in.
- Wall brushes are designed with a higher bristle content to help with picking paint up and holding the coating until contact is made with the surface to spread the paint evenly. The taper on wall and broad area brushes is usually less than with cutting in paint brushes.
- Natural or synthetic fibre is used in manufacturing paint brushes. The most common natural fibre used is hog bristle while synthetic paint brushes are usually nylon filaments that vary in shape or diameter and many have the tips treated to imitate the way natural hog bristle splits from the ends.
- Paint brush handles can be the long and round cutting in style, wall handles, varnish handles and more.
- Even when using a roller a paint brush is usually required to cut in the corners and edges where a roller cannot reach or finish evenly. The paint brush is handy for wiping any leftover paint from the roller tray back into the original paint container.
- Common paint brush widths used by painters are 25, 38, 50, 63, 75 and 100mm
- A ferrule is used to fasten the bristles which are usually held together in epoxy to the handle. A paint brush ferrule is usually made from copper or plated ferrous ferrule.
