Spray painting is a method of applying paint using a spray gun or aerosol can. This technique allows for an even coat of paint over surfaces, making it popular for both artistic projects and industrial applications. It can be used on various materials, including wood, metal, and plastic. The process involves mixing paint with a propellant, which creates a fine mist when sprayed. Spray paint is available in many colors and finishes, such as matte or glossy. Proper ventilation and protective gear are essential during spray painting to avoid inhaling fumes and to ensure safety.
