Spraypaint

Spray paint is a type of paint dispensed as a fine aerosol from a pressurized can. It typically contains pigment, binder, solvent, a propellant, and various additives. The nozzle releases the contents as a mist, allowing even coverage over irregular surfaces. Spray paints are used for decorative finishes as well as protective coatings across art, automotive, construction, and industrial applications.

There are solvent-based and water-based spray paints. Solvent-based products generally offer faster drying and tougher finishes, but emit more VOCs and require venting. Water-based paints have lower odor and environmental impact but may require longer drying times. Finishes range from matte and satin to gloss and metallic, and spray caps control spray width and pattern for different effects.

In art and graffiti, spray paint is valued for rapid coverage and flexibility on vertical surfaces. In industry and automotive work, spray coatings provide uniform protection against corrosion and wear.

The development of aerosol spray technology began in the 20th century and gained mainstream use in the mid- to late-20th century, with spray paints becoming widely available to consumers in the decades that followed.

Safety and environmental considerations include flammability, inhalation hazards, and VOC emissions. Proper ventilation, personal protective equipment, and adherence to local disposal regulations are advised. Many regions regulate spray can emissions and require recycling of empty containers.
