No matter the size of the structure, the painting process follows the same steps, more or less. First, the surface to be painted has to be cleaned of dirt, grit, rust, old paint, etc. Then the area has to be prepared, so that other surfaces remain clean. Then the paint is applied, possibly in multiple layers, beginning with a primer coat. The paint is left to dry, and then the area is cleaned up. However, the methods for carrying out these tasks will differ significantly, depending on the size of the project.
A house that needs painting has walls made of wood or siding, and the interior walls may be wood or sheetrock. With a large industrial project, the walls could be made of metal or concrete. In addition to the walls, many buildings will include steel supports throughout the building. Really large jobs, like a factory or stadium painting in Spartanburg SC, require a whole team of people on the project, different kinds of equipment, and different paint.
The outside walls of a house are cleaned with pressure washing before a painting job can begin. Cleaning a large industrial structure requires high pressure techniques. Depending on the surface that needs to be clean, the painting contractor may use a high pressure water jet. It both washes and blasts away any grit to leave a smooth surface. Abrasive techniques, like sandblasting, are also used for surfaces that can withstand it.
Once the surface is smooth, there are several different methods of applying paint on a large scale. House painters use rollers and brushes, but industrial painters use other methods. One method is airspray. Pressurized air (35 – 80 psi) atomizes the paint and shoots it out the nozzle in a very fine spray that can cover a large area quickly. The disadvantage is that the sprayer can overspray, so that paint is wasted and a lot of clean-up is required.
Electrostatic spray involves using charged paint on a grounded surface. Electrical current is then used to fuse the paint to the wall. This method produces a highly uniform coat, but it is slower and more expensive than other methods. Another type of electrostatic spray uses paint in powder rather than liquid form. The powder is sprayed and then heated so that the powder melts and fuses. If you are looking for Stadium Painting in Spartanburg SC, visit Southernpaintingandsandblasting.com.
