Which sprayed finish category is delivered from a pressurized can?

• A. Aerosol
• B. Air
• C. Airless
• D. Spray Gun

Answer: (A)

The sprayed finish category delivered from a pressurized can is aerosol. In an aerosol system, the finish sits with a propellant inside a sealed can. When you press the valve, the propellant pushes the liquid out through a small orifice, atomizing it into a fine spray right from the can itself. This self-contained setup means you don’t need external equipment to spray the finish.

The other methods rely on separate devices or mechanisms. A spray gun uses an external source of compressed air or a pump to atomize the finish at the nozzle, not from a can. Air spray relies on compressed air to break up the liquid into droplets, again requiring an air source. Airless systems force the liquid through a small orifice under high pressure without using air to atomize it, typically via a pump in a spray tool.
