Spray paint is an aerosol paint supplied in a pressurised tin-plated steel or aluminium canister. The canister is small enough to be handheld for single hand operation. Spray paint can be used without electrical or air based application tools.
Spray paint is incredibly easy to use. All you need to do is remove the lid on the canister and compress the nozzle at the top. Paint will spray from the nozzle as a fine mist. You must always read the instructions for each specific type of paint as application distance varies on paint viscosity and drying time.
Not all spray paints require a primer, but primers can help prepare the surface you want to paint. A primer can smooth the surface so the spray paint will adhere to it more easily as well as giving an even colour base for better coverage with the final paint finish. When using metal paint, primers offer resistance against rust and corrosion. For wood, primers can stop spray paint from penetrating into the surface and causing an uneven coating.
Spray paint is a relatively safe product, but there are some precautions that you can take to minimise risks. You must always use spray paint in a well-ventilated environment and wear suitable PPE (Personal Protective Equipment). Spray paint is flammable and must be kept away from sources of heat and naked flames.
