A Guide to Commercial Paint Spraying

Today we take the notion of spray painting for granted and it is a process used in all of our cars, trucks, even aeroplanes. Spray painting with compressed air has been around since the 1880’s, when it was generally used for spraying whitewash onto walls, which was significantly faster than doing it in the more conventional manner with brushes. It was only after the Second World War though, that aerosol paint was introduced to the market, which has never looked back since. Spray painting involves paint being applied through the use of an air pressurised spray gun, which when triggered mixes the paint with the pressurised air and is released as a fine spray. The process is very flexible and a number of different paint consistencies can be achieved through the use of varying size and shaped nozzles. The two types of air gun spraying processes either employ a skilled operator who applies the paint from 6-10 inches from the object in a back and forth motion to ensure a continuous coat, while in an automated process, the gun delivers the stream of paint from a mounted position.

Different Options and Technologies

Spray painting has far more complexities that just firing paint and compressed air out of a spray gun though, with differing levels of air pressure and paint volume being used, to allow a higher volume of paint to be applied to the surface. Additionally, there are also powder booths to think about and the different types of filtering that needs to be done. This reduces material consumption and any excess paint in the air, which can cause what is known as overspray, as it lands on unwanted areas. Electrostatic paint spraying was discovered in the late 1940’s and works by electrically charging the paint particles and applying an opposite charge to the surface to be painted. The paint is then attracted to the surface, which produces a more even coat, reaches hard to get to places, reduces the amount of paint required and is often used on car panels and motorbike frames. Heavy duty industry sometimes uses an airless spray gun, where the paint itself is pressurised and provides for the use of less thinners, which reduces drying time, allows for thicker coats to be applied, reducing the amount of coats required and gets into every nook and cranny. Extreme caution should be used with this type of spraying as there is the potential for serious injury, given the high pressure at which the paint is expelled.

Despite proper precautions, accidents tend to be inevitable sometimes, giving serious injury to the painting personnel. If the worker is self-employed, he might have to take care of his own medical expenses. However, if he is employed by someone, he might need to consult a lawyer similar to a Portsmouth workers compensation lawyer to secure his rights, if ever such a situation arises. A lawyer would help file the claim and would ensure that the worker receives his fair compensation. It would help the worker financially as well as mentally, as he would be able to focus on the process of healing without being worried about the medical expenses.

Moreover, most vehicles like cars, motorbikes, and superbikes get the surface paint done either as a part of the modification or because their vehicle was in an accident. In that case, if the owner had a motorbike or superbike insurance, they may have to only spend a few bucks on repair and paint jobs. Paint shops that provide such services may have available options for such incidents, so to ensure you don’t have to take up all the burden of repair, you can always invest in affordable and beneficial vehicle insurance.

The Spray Booth

Found in pretty much every decent car repair shop, the spray paint booth is a pressure controlled, closed environment, which is able to deliver the perfect working conditions for paint delivery. It gives the precise humidity, air flow and temperature, and removes through an exhaust system toxic solvents and excess paint, generally after filtering and treatment to prevent outside air pollution. They are equipped with purpose designed ventilation and sometimes with burners, to heat the air and speed up the drying process. Additional systems are often utilised to assist in the extraction of excess paint in the air.

Spray booth manufacturers today are able to provide highly technologically advanced units, which can provide the optimum working environment, maximise workspace and improve drying times remarkably, and can be installed either inside or outside your working premises.
