Before applying a coating of paint or finish to a stainless-steel structure, it’s essential to smooth a rough surface through abrasive blasting. This involves directing an abrasive material against a metal surface under high pressure to strip imperfections and contaminants from the surface. The industrial painting and blasting team at Derrick Company in Cincinnati, OH, discusses the importance of abrasive blasting before painting an industrial metal surface, below.

Why Abrasive Blasting Is Vital Before Painting

1. Prepares the Surface

Abrasive blasting removes imperfections to prepare a hard-surfaced material, such as stainless steel and other metals, for a coating paint finish. It also reduces the amount of time it takes to prep the surface when compared with traditional methods using hand tools.

2. Removes Rust & Corrosion

Over time, rust damages and degrades metal surfaces, and in some cases, even destroys the structural integrity of heavy metal machinery. Abrasive blasting strips away the rust and corrosion to restore the structure to optimal condition. Painting over this exposed surface protects it from the oxidation process.

3. Increases Longevity of the Coat

Abrasive blasting leaves an anchor pattern on the material to improve adhesion. It also helps to facilitate a bond between the surface and the protective coat, which increases the longevity of the material. It also cleans surfaces better than traditional techniques.
