Changing Surface Properties for Improved Adhesion

Sandblasting is a process that harnesses the raw force of abrasive materials to transform the surface adhesion properties of steel. Whether you’re seeking to understand the science or looking to improve your steel-based products, this article is your gateway to understanding the effects of sandblasting prior to the application of protective coatings.

Sandblasting is a technique that goes beyond just surface cleaning; it’s a method that can greatly improve the adhesive properties of steel. Imagine steel surfaces that not only become clean but are also exceptionally suitable for adhesion. This is the promise of sandblasting, an art and science that holds immense potential for various applications.

How Sandblasting Works

At its core, sandblasting involves the use of abrasive materials, often garnet or similar particles, propelled at high speeds to remove rust, paint, contaminants, and imperfections from steel surfaces. However, its impact doesn’t stop at cleanliness. The abrasive action roughens the surface, creating microscopic nooks and crannies. It’s within these tiny imperfections that the magic of enhanced adhesion happens.

Benefits for Steel Adhesion

The study “The Effect of Sandblasting on the Surface Properties of Steel for Adhesion” published in the journal “Surface and Coatings Technology” in 2016 [] researched the effects of sandblasting on steel surfaces. Researchers explored various sandblasting parameters, including pressure, angle, and abrasive type, to understand their influence on surface properties.

The results were eye-opening. Sandblasting significantly improved the surface properties of steel for adhesion. The roughness of the surface increased with higher sandblasting pressure and angle. This increased roughness provides more surface area for adhesives or coatings to bond to, resulting in stronger adhesion.

Not only did roughness improve, but so did wettability and free energy. Higher sandblasting pressure led to increased wettability, making it easier for adhesives to spread and adhere effectively. Additionally, the free energy of the surface increased, which is crucial for creating a favourable environment for adhesion processes.


In conclusion, sandblasting isn’t just about cleaning; it’s a powerful tool for enhancing steel adhesion. The study’s findings underscore the importance of choosing the right sandblasting parameters for specific applications. By optimising pressure, angle, and abrasive type, you can tailor the surface properties of steel to meet the demands of your project.

Whether you’re in the manufacturing industry, construction, car restoration or simply curious about the science behind sandblasting, understanding its impact on steel adhesion is invaluable. Remember that the surface transformation sandblasting offers can be the key to unlocking enhanced performance, durability, and reliability in your steel-based products.
