Spray painting was invented in 1892 and whilst it might not require the imagination of Picasso or Constable, it does need a high level of skill to do the job well.
But why do we need to spray paint machines in the industrial sector? Why not just leave the manufactured machines in their original state?

The answer is two-fold. Spray painting not only protects the customers’ machines against rust, but it makes the machines look good!

Six spray painting methods

  1. Air gun spraying
  2. HVLP (High Volume Low Pressure)
  3. LVLP (Low Volume Low Pressure)
  4. Electrostatic spray painting
  5. Air assisted airless spray guns
  6. Airless spray guns

The main variables that industrial spray painters consider when undertaking a job are as follows:

Substrate Preparation

Substrate is the preparation of the surface that requires painting. Painters have to ensure that the substrate is cleaned properly for even and proper painting. It is a proven fact that as high as 80% of all paint jobs fail because of improper preparation of the surface before painting.

Paint Thinning

There are times in the painting process when the paint needs to be thinned out for proper application and coverage. Thinners are different from each other on the basis of what they can dissolve, their odour and their flammability. For most paints, mineral spirits, along with an alkyd or oil base, can be used for thinning but there might be other paints that require other types of thinners.


The actual spraying also requires great care and precision on the part of the painter. Variables in the spraying process include the type of paint finish that is required, the type of paint being used and the substrate type.  There’s a large variety of spraying devices and guns that can be used so industrial painters must consider all the variables and chose the right spraying device to achieve an evenly distributed and smooth finish.  Painters also have the flexibility to choose the amount of pressure that the paint is applied with and this is measured in pounds per square inch.
