| Applicator |
A nozzle, gun, or wand utilizes the Venturi
effect to coat a surface. The tools are meant to be handheld or used
in an automated paint spraying system. These dictate the pattern,
droplet size, angle, and intensity of the spray. Some spray systems
support multiple applicators. |
| Power source | A powered paint sprayer is supplied by either a gas-powered or electric motor, whose operational strength is rated in horsepower. |
| Pressure source | An air compressor or pump feeds the surface coating through the painting system. This contributes to the flow rate of the paint and pressure is represented in PSI. Turbines are also commonplace. |
| Media | A variety of surface finishing liquids can be applied by a spray system, though latex or oil-based paint is most common. Other agents may require thinning to be used in spray systems. |
| Reservoir | The system's integrated basin for paint awaiting application. These range in size from small cups to paint drums. |
| Handling equipment | Large, heavy-duty paint spraying systems, or systems meant to paint outdoor terrain, often require a truck or cart for transportation or operation. |
| Application enclosures | Since between 20 to 40 percent of the spray can be lost due to overspray and droplet drift, spray booths keep wayward particles within an enclosure. These range in size from cabinets to garage-like environments to accommodate a variety of components. |
| Ventilation equipment | Due to the airborne concentration of minuscule paint droplets, respirators and ventilation equipment are often legally-required components in the spray painting process. Spray booths often incorporate a blower or overhead hood. |
| Electrode | An electrode is immersed in the reservoir, attached to the applicator, or used to create an electrostatic field. This charges the paint, and the component to be sprayed is oppositely charged or grounded. The paint is attracted to the component to greatly increase coating efficiency. |
| Curing units | Convection and infrared ovens are used to expedite the drying process of certain paints and surface coatings. |
| Spinning bell/disc | A spinning bell or disc is used to atomize and electrically charge the paint particles via centrifugal forces. An airstream directs the paint towards the part, which has been charged or grounded. |
| Part feeder | In high volume spray applications it can be beneficial to have a conveyor or part placement system to assist in moving unfinished and finished components between processes. |

Generally speaking, there are four methods
utilized to produce droplet-sized particles and impart direction
upon the spray agent. This technology in conjunction with the
applicator determines if the spray pattern and intensity.
Airless: Paint spraying or application system using
high fluid pressure to atomize paint by forcing it through a small
orifice. Paint under high pressure is passed through a nozzle and
broken down into droplets, or "atomized," where it enters the lower
pressure region outside the gun tip. (Less air is used than in
conventional air spraying so that the problems of dry spray and
paint bounce-back is reduced.)
Airless (air-assisted):
Air-assisted airless spray process is used to alter the spray fan
shape pattern, but not to atomize the paint.
Air atomized: Paint
application system wherein paint is atomized by combination with
compressed air. System of applying paint in the form of tiny
droplets in air, i.e., paint is broken down into droplets, or
"atomized," by a spray gun as a result of being forced into a high
velocity air stream. Shape and paint density of the resulting
droplet cloud can be controlled by air pressure, paint viscosity,
and gun tip geometry.
Rotary cup/disc: Rotary spray
guns or applicators use a rapidly spinning cup/bell or flat disc to
project powders or atomize paint. Rotary cup or bell rotary
applicators produce a fan pattern, which is closer to a nozzle spray
gun. A rotating head is shaped to deliver paint forward in a
circular pattern. The bell may be directed at any angle and be moved
on robots or reciprocators, just as nozzle spray guns are. Disc
rotary applicators spin the coating media out radially. Rotating
heads that deliver paint horizontally 360° around the head are
useful on omega loop conveyor finishing lines. A disk is usually
mounted horizontally on a vertical reciprocator. Disc rotary spray
guns are also useful for internal or ID coating applications.
In an effort to reduce energy and material consumption, many spray
painting operations systems utilize high volume, low pressure (HVLP)
or low volume, low pressure (LVLP) systems to spray coat items with
large surface areas. These spray techniques are often driven by
turbines, not compressors.

Did You
Know? Sydney Harbour Bridge gets a fresh coat of paint — again Daily Telegraph 3 January 2015 SYDNEY Harbour Bridge has an annual $20 million maintenance budget, with its exposed surfaces needing to be repainted every five years, while other parts of the structure last 30 years without a new coat. IT’S one of Sydney’s great urban myths — when the painters on the Sydney Harbour Bridge get to the end, they go back to the beginning and start all over again. Wrong. The reality is that there are sections of the 52,000-tonne structure that have not felt the tickle of a paint brush for up to 30 years. ![]() Justin Buhs, a senior painter on the Sydney Harbour Bridge, paints rivets by hand.

Picture: Chris McKeen (Source: Daily Telegraph) With close to 500,000sq m of steelwork to be painted and kept free of rust, a crew of 15 workers is needed to help what its builder John Bradfield called the “blue arch of Heaven” looking her best. The bridge’s owners, Roads and Maritime Services, even use two robots to blast away the old lead paint from internal sections of the Bridge. Sydney Harbour Bridge works manager, Waruna Kaluarachchi, in charge of the bridge’s annual $20 million maintenance budget, said its exposed surfaces need to be repainted every five years while others last 30 years without a new coat. “We can’t start at one end of the Bridge and start painting until we get to the other end,” Mr Kaluarachchi said. “It doesn’t work like that.” It would take about 30,000 litres of the traditional “Sydney Harbour Bridge Grey” paint to do just one coat. The paint is a registered trademark colour and not for sale on the open market. ![]() Support beams under the Sydney Harbour Bridge, on the northern approach.

Did You Know? Air spraying. Using atomization, air sprayers apply color through a fine mist or spray. They also gives a smoother finish compared to other methods. Airless sprayers. These sprayers use higher blowing pressure, so they're more efficient for covering large areas. However, they also require the user to wear personal protective equipment (PPE). Spray painting equipment refers to the collection of devices used to apply a surface coating to objects by the means of atomized liquids that are propelled through the air, usually by compressed air. It also refers to a series of devices used to optimize the coating application. A paint, stain, ink, varnish, lacquer, or polyurethane is pressurized and forced into droplets or aerosol by a high-velocity airstream that also serves to distribute the coating on a surface. The spray is patterned onto the workpiece by an applicator, and cleaning and curing equipment helps perfect the paint's adhesion. (Source: GlobalSpec) |
Vehicle Painters prepare surfaces of vehicles, match and mix colours
and and apply primer and finishing coats of paint. They may paint
new or damaged cars or apply designs or signs.
Spray painters
prepare surfaces of vehicles, match and mix colours, and apply
primer and finishing coats of paint. Powder coaters apply paint and
other industrial coatings to vehicles and a range of other
manufactured items. They inspect the vehicle or surface they will be
painting, clean and prepare it, remove rough spots and sand or treat
the surface, apply an undercoat to the surface, and mix and prepare
the paint for application. They may use computerised paint mixing
technology to do this. They spray-paint or powder coat the vehicle
or article, check the quality and depth of their paintwork and
polish the finished product.

Working conditions
Powder coaters either work in automotive body repair shops and panel beaters, or in industrial workshops, factories and paint shops. Conditions may be noisy, and they may be on their feet for extended periods. Some Powder coaters may travel to perform their work on-site. They work regular hours but may be required to work overtime depending on their workload. They are exposed to paint in particle form, which can be highly toxic, and requires that they wear protective gear such protective clothing and face masks.

Manual Dexterity Is Important in Auto Painting Careers
As most of the work is done by hand, good manual dexterity is an
important trait in auto painting careers.
A steady grip and good hand-eye coordination will go a long way.
Being in good physical shape is important as well, as auto painting
can require long periods of standing, crouching, bending, or
kneeling.

Apprenticeships R US)
Tools and technologies
Powder coaters use a range of different paints and spray guns, including powder-coat and electrostatic spray guns and metal arc spraying equipment. They also use sanding and grit-blasting machines, cleaning and rinsing materials, pre-treatment tanks and a range of chemicals. They are usually required to wear protective clothing including masks. Some spray painters may be required to drive fork-lifts, cranes and trucks to travel to jobs or reach areas to be painted.
Education and training/entrance requirements
You can work as a Vehicle Painter without formal qualifications if you are able to demonstrate your technical competency to employers. However, a certificate III in Automotive Refinishing Technology or another relevant vehicle painting course is usually required. This course is often completed as part of an apprenticeship.
To become a spray painter you usually have to complete a VET
qualification in Automotive Refinishing Technology or Surface
Preparation and Coating Application. You may need to be employed as
an apprentice or trainee in vehicle or industrial spray painting to
undertake these courses. Employers generally require junior
secondary school certificate or equivalent.
Vehicle spray painters may need to be certified, have a motor
vehicle repair licence, or work under the supervision of a licensed
repairer.
You can also undertake a traineeship in surface preparation and
coatings application. The traineeship usually takes 36 months to
complete.
To work as a powder coater within the motor vehicle industry you
usually need to undertake a vehicle painting apprenticeship. The
apprenticeship usually takes 42 to 48 months to complete and is
available as a school-based apprenticeship.
To work as a powder coater in the motor vehicle industry in
Australia, you will need to obtain a Motor Vehicle Repairer's
Certificate. An Australian Police Certificate is required to gain a
Motor Vehicle Repairer's Certificate.
To work as a vehicle painter in NSW, you must be certified by NSW Fair Trading. To work as a vehicle painter in the ACT, you must have a motor vehicle repair licence, or work under the supervision of a licensed repairer.
Employment Opportunities
Overall employment of spray painters is projected to grow slower
than the average for all occupations.
A number of international companies in the vehicle manufacturing
industry are in the process of closing their Australian operations.
However, as with many skilled manufacturing jobs, employers often
report difficulty finding qualified workers. Therefore, job
opportunities should be good for those with industrial spray
painting experience.
Vehicle painters work for crash repair firms and motor vehicle manufacturers. Some are self-employed, usually in partnership with panel beaters. Experienced vehicle painters may become representatives for paint manufacturers or assessors with insurance companies.
Did You
Know?![]() To be a great automotive painter, you need to have a great eye for colour. If you can tell the difference between subtle differences in tint, then automotive painting might be for you. Car companies have put out vehicles in tens of thousands of colours over the years, and even cars painted the same colour on the factory floor might look different after a decade or more of varying conditions, so painters need to have a keen eye to be able to accurately identify and replicate every colour they see. Blending and matching is a big part of the job, and this is where a lot of the creativity and artistry comes in, particularly for custom or specialized paint jobs.

Metal surface finishers work in metal
fabrication and engineering production operations. Electroplaters
control plating processes and maintain solutions used to coat metal
articles and other parts with non-ferrous metals.
They finish metal products by cleaning, polishing, filing or
bathing them in acid solutions. They also apply protective and
decorative coatings.

Electroplaters (metal platers) coat metal plates and objects, such as
car bodies, with a protective layer of metal to prevent rust or
create a decorative finish. They start by cleaning the item to be
plated and covering areas not to be plated with resistant wax or
tape. Then they dip the item into or brush it with a plating
solution, pass electric currents through the plating solution to
oxidise the item, and finally remove and dry the freshly-plated
item.
