The origins of spray paint can be traced back to the early 1880s, when Joseph Binks, a maintenance supervisor at a Marshall Field store in Chicago, rigged a cold-water-operated hand pump to whitewash the basement walls of the store. In 1893, Binks used his new spray system to paint the buildings at the World’s Columbian Exposition in Chicago. Known as the White City, the buildings took far less time to whitewash with Binks’s contraption than they would have with rollers or brushes. In 1949 an aerosol spray paint can was invented. Today’s aerosol spray paint cans contain compressed air that propels paint out of a spray nozzle. It’s important to use a quality nozzle—or cap, as some makers call it—so you can properly control your paint flow and get the right spray pattern. Browse our selection of the best ones below.
