How Industrial Painting Works

Industrial painting is very different from interior or exterior home painting. Instead of rollers and paintbrushes, the industrial painters may use spraying machines or hoses to apply paint. They are usually working on much larger surfaces than just a single building or something as small as the typical house.


To work on large surfaces, they must use special application techniques and tools that are into usually unavailable to conventional painters. They also must prepare the surfaces they are painting in specific ways to ensure that the paint stays on properly for years to come.


Methods of Painting

A lot of the surfaces that industrial painting is used on are massive structures like bridges, tunnels, large buildings, hangers and the like. Sometimes, industrial painters must paint many structures over short period of time, which is why they may use large paint application machines. To prevent over-spraying, though, the painters may use an electrostatic discharge on the area to be painted. Spray coating is an excellent way to apply resins and sealants as well.


Coil coating may be used for large metal surfaces. This is a roller-type application, and it applies paint continuously over a large surface. It works best on metal surfaces, and it is incredibly fast.


Powder coating is more versatile, and it can be used on a number of different surfaces. The surface area must first be treated with an electrical discharge before the powder coating can be applied, though. Originally, powder coating could only be used to apply paint to metal, but advances in technology have opened the door for wood and plastic to be covered by this same application method.


Preparing the Surface

Preparation of the surface is a major part of industrial painting. For the paint to have long-lasting appeal and to be stable for years to come, the surface needs to be carefully prepped.


The first step is usually to blast the surface area with water. Using a high-pressure hose, the painters can remove dirt, grime and any loose particles. Jet streams of water are excellent for prepping the surface to painting and ensuring that the area is smooth enough to paint on successfully.


It is the preferred method of preparation because it can be used in any kind of weather with great results and it does not have any sort of negative environmental impact. It also gets the surface cleaner than any other method of preparation. Industrial painting contractors may also use abrasive preparation techniques. This can be done many ways, and it can involve either wet, dry or both wet and dry preparation of the surface. This removes particles from the surface and makes the area smooth and suitable for painting.


In many cases, the surface will be treated with some sort of electrical discharge. This can ensure that excess paints run off and that the applied paint sticks perfectly to the surface, and it is not something conventional painters would ever have reason to use.
