Behind every successful construction project is a team of industrial painting contractors. They work in the background to coat building surfaces with paint until it is completed. Who are they, what do they do, and why are they providing critical services to many construction and engineering projects?
Specialties of Industrial Painting Contractors
Any construction project involving the application of coating systems would have painting contractors who are busy at any of the following activities:
1. Surface preparation. Careful surface reparation is often the key to coating systems that perform well and last longer. For new construction, surface preparation is much easier when the surface is bare, such as a slab of concrete. If a previous coating system has been installed, industrial painting contractors laboriously remove the existing coat. This is a skill that requires deep expertise and experience.
Often, industrial painting contractors wash the surface to clean it, and perform water-blasting with the use of high-pressure water jets. Dust, dirt and loose particles are removed from the surface, leaving it clean. Industrial painting contractors may also use abrasive surface preparation to clean the surface.
2. Paint selection. Prior to actual coating application, painting contractors determine the type of paint that will be used. The choices can run from water-based latex or acrylics, to oil-based systems. The correct paint has higher adhesion to the target surface, for durability and high performance.
3. Coating application. Industrial painting contractors may use a plethora of tools and methods to apply the paint to the surface. Brush and rollers are standard tools. In some cases, powder coating is used, which is a process that electrostatically applies dry paint particles unto grounded surfaces. When heat is applied the powder coating is cured permanently in place. Roll coating is also another method used by … Continue Reading
Industrial painting contractors use a variety of methods to coat surfaces with paint. Unlike home decorators there are many more ways to lay down a layer of paint than just by applying it by brush or roller. In addition, the surfaces in industrial painting tend to require a lot more thorough preparation.
Preparation is usually the key to proper long lasting paint applications. If the surfaces to be painted have not had paint applied previously, then the process is somewhat easier. If a previous coat exists, then its removal is usually required, and this in itself is a skill that needs an expert touch.
Surfaces can be prepared by using ultra high pressure water jets, or water jetting as it is also known. This has both a washing and a blasting effect, which can remove grit and dust as well as any other loose particles. Water jetting leaves a surface cleaner than any of the other methods of preparation. It can be used in all weathers and it has no adverse environmental effects.
Abrasive preparation is also used by industrial painting contractors. This can be dry, wet, or a combination of wet and dry. In this way rust, grit, dust and chemicals can easily be removed to leave a virgin surface ready for the paint application. When sufficient care and attention is taken over the preparation process, the painting process is made easier with a greater likelihood of a successful outcome.
In industrial painting, applying the paint with a brush or roller is not the only option. Powder coating, for example, is a process where particles of dry paint have an electrostatic charge applied before being positioned on a grounded surface. The particles are held on the surface by electrostatic attraction. Heat is then applied, which allows the powder coating … Continue Reading
