Spray painting is a process that uses devices called spray paint guns to atomise a stream of paint exuding the fluid nozzle and convey that paint onto the surface of the item to be painted. This is a short post discussing a few of the different types of paint spray guns available.
It is essential when spray painting to wear safety glasses, a face breathing mask to filter out harmful fumes and particles, protective gloves to protect the skin from chemicals and appropriate workwear to also protect the entire body from contact with potentially harmful solvents and paints.
Typical paint spray gun equipment involves a spray gun designed to be held in the hand, more often than not an air compressor and a paint vessel either attached to the spray gun directly or connected to the spray gun via hoses.
Paint is delivered to the spray gun via the directly attached container or through the attached hoses and paint is atomised with streams of compressed air directed into the paint exuding the gun, or in the case of airless paint spray guns the paint is atomised by the velocity of the paint stream as it hits the atmosphere on exiting the airless spray gun.
Other types of air spray paint guns such as high-volume low-pressure, HVLP or low-volume low-pressure, LVLP are essentially the same as conventional air paint spray gun equipment that use different amounts of air pressure and compressed air volume to enhance paint transfer efficiency.
One of the simplest types of spray painting equipment that almost everyone will be familiar with is the compact pressurised aerosol spray pack which can be typically purchased from supermarkets and almost all hardware stores.
Many artists and hobby enthusiasts use smaller paint spray gun equipment and even paint, airbrushes to apply paint in fine detail to smaller areas.
