A painter's tool is an essential part of any painting job. The most common tools used by painters are a ROLLER, a SPRAYER, a SCRAPER, and a spraygun. A ROLLER is a cylindrical tool with a handle that is used to spread paint evenly over a surface. A SPRAYER is a device that sprays a fine mist of paint onto a surface. A SCRAPER is a tool used to remove paint from a surface. A spraygun is a device that uses compressed air to atomize paint into a fine mist for spraying onto a surface.
