A paste brush is a type of brush used for applying paint or similar substances to an area. It is generally used for large surfaces or areas, rather than small details. The bristles are made from soft material such as nylon, and are designed to spread the paste evenly over the surface.
Paste brushes are available in a variety of sizes, with different numbers of rows of bristles.
The term Pasting brush can be defined as, or has a description of “Used for applying wallpaper paste to large areas.”
