Sandblasting

Sandblasting is a critical step in cleaning and preparing metal surfaces. During this process, metal surfaces are cleaned and smoothed with high-speed sand or other abrasive materials. Sandblasting effectively removes rust, oxides and other contaminants from metal surfaces, which allows the surface to adhere better to primers or coating materials. After the sandblasting process is completed, a primer, usually called “shop primer”, is applied to the surfaces. Shop primer covers metal surfaces with a protective layer and increases their resistance to corrosion. In addition, this primer prepares a suitable base for subsequent coating processes and contributes to the longevity of the metal surface.

After sandblasting and shop primer application, there are several other important steps to take before moving on to the final processing and coating phase of the surfaces. These include constantly checking the surface cleanliness and correctly monitoring the drying process of the primer. After the primer application, a careful inspection should be made to ensure that the surface is properly and evenly coated. In addition, the primer application area must be protected from moisture, dirt and other external factors, as these factors can affect the performance of the primer. The applied shop primer not only provides protection against corrosion, but also ensures that subsequent coating materials are fully compatible with the metal surface and last for a long time. Therefore, all these processes must be carried out meticulously and quality control stages must not be neglected.
