Spray painting technology has improved a lot over the last ten years or so. It has diversified greatly and there are now many different systems for delivering paint and surface coverings for every type of application imaginable.
This technology has become popular due to the benefits and advantages spray painting has over conventional methods of applying paint. One of the main benefits is that it is so much faster to cover large areas and easier for the worker using the equipment.
The results are often much smoother and more uniform than brush painting but there are a few drawbacks to spray painting. One of the disadvantages are overspray where the atomized paint drifts onto surfaces nearby, and blowback which is where the already dried paint bounces back from the surface the nozzle is aimed at, to land elsewhere.
Then there is the efficiency to consider, although faster in application, spray painting tends to only result in between 20%-50% paint reaching the target surface, the rest being wasted in overspray and blowback. This contrasts sharply when compared to brush painting which, although slower, will give a much higher percentage of the paint actually making it to the desired surface. This aspect depends a lot on the skill of the spray painter, the pressure setting, the type of nozzle used and if the operator is triggering the gun at the beginning and end of each spraying pass.
Spray painting is crucially important for coverage on metallic and other very smooth surfaces and produces stunning results when applied correctly, but it does have its limitations. When covering a knobbly or stucco surface with spray paint the operator has to do it in a number of passes holding the spray gun at several angles in order to cover it properly or go over the surface afterwards with a roller or brush. Spray painted exterior surfaces will not adhere to the surface for as long as conventional brush or roller applications. This issue is becoming irrelevant ,however, because new paints and materials based on acrylics and plastics are giving better and longer lasting results now.
Loss of paint due to overspray and bounce back can be reduced by using a spray booth when it is feasible to do so and the combination of lower pressure, specialized nozzles and spraying systems and materials have made a big dent in the problem.
We now have High Volume, Low Pressure spray guns that allow us to spray in all sorts of locations, paint viscosities and with very high quality results when the operators are properly trained and experienced. There are now highly specialized spray painting nozzles and guns that allow us to spray paint in awkward and hard to reach areas, recesses and all environments. There are electrostatic spray systems that make it possible for the paint to be drawn electrically to the oppositely charged surface, vastly reducing overspray and therefore reducing waste.
There is now a dedicated spraying system for every job imaginable for all kinds of commercial and industrial applications to cover ever type of surface. As long as the operators are well trained and the surfaces to be painted are appropriately prepared before painting. ICS spray nozzles are specialists in this field and definitely worth checking out if you are looking for any kind of specialized spray nozzles.
