Spray paint is a liquid paint that can be dispensed via a spray nozzle, commonly found in cheap and easily transportable aerosol cans. It is used for various painting applications, including graffiti. Airbrushes and spray guns are also forms of spray paint. However, all forms carry potential health risks and should be used in well-ventilated areas with protective gear.
Spray paint is a liquid paint that can be dispensed onto a surface via a spray nozzle. The term is usually applied to paints of various colors that are available in cheap and easily transportable aerosol cans. The paints used in airbrushes and spray guns are also forms of spray paint, but in common usage, the term “spray paint” is synonymous with the form of the spray can, also called “spray paint.” The paint can be used anywhere paint is used, but is particularly connected to municipal signage and the underground art form called graffiti.
Spray paint is available in a wide variety of colors from any store that carries paint or hardware supplies. The cans are easily stored and transported and are popular for a wide variety of painting applications. The pressurized gas pushes the paint out of the can in an even stream, usually eliminating the need for brushes or rollers to spread the paint across the surface. Most cans include a ball inside to mix the paint, resulting in a clinking sound when the can is shaken.
Spray paint can be used to create marks and symbols quickly and neatly, often by applying a stencil that blocks paint from all but the desired area. This process also lends itself to graffiti, the practice of painting messages or artwork onto buildings, bridges, sidewalks, or any other surface, often illegally. Many cities have laws governing the sale of this paint and other materials because of graffiti. While often identified with vandalism, not all graffiti is illegal; some owners see it as an art form and allow or even commission it.
Airbrush and spray gun paints are also forms of spray paint. An airbrush is a tool that uses compressed air to concentrate paint in a very specific area. They are often used for detail-oriented work, such as retouching photographs, because of this accuracy. Spray guns work on a similar principle, but often employ wide nozzles to cover a larger area. They are used in industrial applications such as the mass production of automobiles, building materials and houses.
All forms of spray paint carry potential health risks, because they release tiny particles of paint into the air. While most of this goes onto the painted surface, some is lost to the surrounding air as overspray. Unprotected painters can inhale the overspray into their lungs, where it can cause immediate or long-term health problems. The propellants in aerosol cans can pose similar dangers. The United States Environmental Protection Agency recommends spray painting in well-ventilated areas and the use of respirators, gloves, and protective clothing to prevent exposure to chemicals.
