Sandblasting is the process of roughening the surface to a certain extent by abrading the oxide layer, dirt, oil, slag, old paint or coating on the surface. The purpose of the sandblasting process is to extend the life of the sandblasted surface.
Sandblasting is applied to the surface by impinging sand or metal materials of various diameters under high pressure, removing unwanted layers and creating a surface for the new coating material.
In the sandblasting process, the surface is cleaned, abraded and roughened for the new coating material, usually by using materials such as fine sand, silica sand, plastic, crete, steel ball.
Sandblasting can be applied to all kinds of steel, metallic surfaces, marble, concrete, glass and wood surfaces.
Sandblasted surfaces are generally named by the Swedish standard. The most commonly used dimensions in this nomenclature are SA1, SA2, SA2,5 and SA3.
PAINTING is done to protect the blasted or cleaned surface from the abrasive effect of oxide, moisture or different foreign substances. Painting is the most basic element that increases the life of the surface.
Paint is applied to the properly roughened surface with the right materials and application methods. This application can also be done with a pressure gun or hand tools (brush, roller, etc.).
While the painting process may vary depending on the specification and details, it is the general application method as primer, undercoat and topcoat.
