Expert Advice On Car Spray Paint Systems From Eastwood
Anyone that has painted a car knows that conventional spray painting is messy and expensive. Standard high-pressure spray systems waste too much costly paint and solvent as useless over spray, which requires an additional investment in masking materials and cleaning supplies.
Rather surprisingly, the US government helped make our paint jobs easier and less expensive. It started with pollution control: as part of a far-reaching effort to reduce air pollutants. The Environmental Protection Agency (EPA) and state governments created laws covering Volatile Organic Compounds (VOCs). These compounds combine with other substances naturally found in our normal breathing air. To form harmful "ground level ozone". New regulations intend to fight this type of ozone formation. One way to accomplish this is by establishing standards for spray painting " Transfer Efficiency", or the percentage of sprayed paint that actually adheres to the desired surface.
Conventional high-pressure spray painting yields a transfer efficiency of about 20-25%, which means 75-80% of the paint is wasted. To meet new government regulations, heavy industry developed new High Volume Low Pressure (HVLP) systems that are about three times more efficient (75-80% efficiency) than traditional sprayers. Quality paint is very expensive, so a system will justify its costs with one or two big jobs (such as a house or collector car).
Home shop paint over spray is more than just an unnecessary expense, it's one of the most difficult and messy nuisances in a restoration project. The acid- etch primers, which bite into everything from freshly finished fenders to your tool box, tools spare parts & every piece in its path (old style lacquer primers used to dust off the surfaces). Controlling over spray is a big help in keeping your shop clean.<"p>
An HVLP system lets you use techniques developed for heavy industry in a home shop. As you help preserve a healthy environment, you also save a considerable amount of time and money.
