How To Spray Paint

As an alternative to using a pressure pot in conjunction with spray painting, many manufacturers offer a range of double diaphragm pumps that basically perform the same task.

Although a double diaphragm pump has many more moving parts and is much more complex than a simple pressure pot there are several benefits which may make the additional cost of a double diaphragm pump viable in certain spray painting environments.

Before undertaking any type of spray painting is essential to ensure that safety issues are addressed. While not all encompassing here are a few basic spray painting safety suggestions to consider maintaining.

Most air compressors have a maximum static air pressure of between 100 to 120 PSI, 689.5 to 827.4 Kpa, at which point the air compressor pump turns off. This amount of air pressure is way too high for spray painting with an air spray gun so an air pressure regulator is used.

Spray painting with HVLP turbines as with any type of spray painting system has advantages and limitations. One of the most outstanding advantages of using a HVLP turbine for spray painting is the high level of portability.

Following any spray painting job with an air spray gun being either conventional, HVLP, or LVLP type, the following cleaning and basic disassembly and reassembly steps are usually recommended.

Remove any remaining paint from the pot and to save solvent spray gun pot could be wiped clean with paper towel which can be easily discarded once the paint is dried. Pour a small amount of solvent into the pot and swish around to clean then spray the solvent through the gun. Add additional solvent as required until no further colour is spraying from the gun.

Spray gun pressure tanks or pots.

Using paint pressure pots to spray paint can have many advantages and speed up production spray painting processes considerably.

One of the most obvious benefits of using a remote pressure pot rather than a suction or gravity paint pot attached to the spray gun is the weight reduction and the ability to manoeuvre the spray gun into any position due to the removal of the paint pot from the gun.

Typically most air spray guns will have two primary controls or adjustments which allow the gun to be adjusted for optimal paint atomisation and spray fan pattern adjustment to suit the object being spray painted.

These two main spray gun adjustments are firstly the fluid control adjuster and secondly fan pattern width control adjuster.

Are HVLP spray guns the final answer to paint over spray?

If you believe much of the marketing hype and even regulatory data many observers can be misled into believing that HVLP spray guns have virtually no paint over spray, are a brilliant new paint spray gun technology, and surpass any other type of spray gun technology that is available.

Simple spray painting techniques can help achieve a high quality spray painted finish. Work on incorporating these techniques to ensure a quality result is achieved each time you use your spray gun.

Always strain the paint prior to spray painting. Even brand-new cans of paint can contain particles which may blemish the final spray painted finish.

Always test the spray gun with water or thinners before attempting to spray paint to ensure the spray gun is functioning correctly.

Require HVLP spray gun capabilities, however, with less compressed air flow demands but still wanting reduced over spray levels? Low-volume low-pressure LVLP spray paint guns could be your answer.
