The Wooster 2-1/2" Acme Chip Brush is a versatile tool intended for applying various coatings, including paint and glue, to surfaces. Its 2-1/2 inch width determines its coverage capabilities and makes it suitable for a wide range of painting tasks, such as staining, varnishing, and touch-ups in hard-to-reach areas. The use of "Acme" in the name typically indicates that the brush handle follows a standard thread size, enabling compatibility with standard extension poles or handles. These chip brushes are typically made from natural bristles like china bristle or hog hair, or from synthetic bristles. They are known for their adaptability, affordability, and ability to work effectively with different types of coatings.
