Benefits of Abrasive Blasting:
Abrasive blasting offers several benefits for industrial applications, including:
- Efficient Surface Preparation:
Efficient surface preparation is critical to the success of any project that requires surface coating, painting, or restoration. Abrasive blasting is one of the most efficient surface preparation methods available. It quickly and effectively removes contaminants, rust, and old coatings from surfaces, leaving them clean and ready for further treatment.
The use of abrasive blasting eliminates the need for manual cleaning, which can be time-consuming and labour-intensive, especially when dealing with large surface areas. With abrasive blasting, the process can be automated, reducing the time and labour required to prepare the surface.
Abrasive blasting also ensures that the surface is evenly cleaned, removing all contaminants and leaving a consistent surface profile. This ensures the coating adheres properly to the surface, creating a long-lasting, durable finish. In contrast, manual cleaning may leave behind small pockets of contamination, which can compromise the integrity of the coating and reduce its lifespan.
Moreover, abrasive blasting provides an efficient way to remove rust, corrosion, and other surface defects. These issues can significantly compromise the structural integrity of the surface, making it more susceptible to further damage and failure. By removing these defects, abrasive blasting helps to restore the surface to its original condition, increasing its lifespan and durability.
Abrasive blasting is a cost-effective solution for surface preparation for a variety of reasons. One of the main reasons is its efficiency in removing old coatings and rust, which reduces the amount of labour and time required for the job. This translates to significant cost savings, especially for large-scale projects. Abrasive blasting can remove coatings and rust in a fraction of the time it would take with traditional methods, such as scraping or sanding.
Additionally, abrasive blasting is a precise and controlled process, meaning there is less material waste than other methods. This not only saves on material costs but also reduces the amount of waste that needs to be disposed of, which can be expensive.
Furthermore, abrasive blasting is a one-step process that can remove multiple coatings and rust layers, eliminating the need for additional steps and products to complete the job. This saves on product costs, time, and labour.
Finally, abrasive blasting can prolong the lifespan of equipment and structures, which can save on replacement costs in the long run.

Removing Rust, Restoring Life
Rust is a common problem that affects metal surfaces, causing deterioration and weakening of the structure. Removing rust and providing protective coatings are crucial to ensure the longevity and durability of metal structures. One of the most effective methods of removing rust is abrasive blasting. However, the level of rust and the type of surface preparation required depends on the rust grade and class of blast cleaning, according to AS1627.9. Neumann Industrial Coatings is a professional abrasive blasting service provider that understands the importance of rust removal and surface preparation according to the appropriate standards.
According to AS1627.9, there are four different rust grades, each with its own set of guidelines for blast cleaning. These grades are based on the level of rust and corrosion present on a substrate surface and are identified as A, B, C, and D.
- Grade A is the least severe rust grade, with only light rust staining or discolouration present on the surface. The guidelines for blast cleaning this Grade require that the surface be cleaned to a minimum of Sa2.5, which means that all visible oil, grease, dust, dirt, rust, and other foreign materials must be removed from the surface. This level of cleaning is suitable for surfaces that will be painted or coated with a protective layer.
- Grade B is characterized by the presence of light to medium rust staining and a light coating of loose rust and scale. To achieve the necessary level of cleaning, the surface must be blasted to a minimum of Sa2.5. In addition, all tightly adhering rust and scale must be removed, leaving only slight staining or discolouration on the surface.
- Grade C is a more severe rust grade, with medium to heavy rust staining and a moderate coating of loose rust and scale. To achieve the necessary level of cleaning for this Grade, the surface must be blasted to a minimum of Sa2.5, with all tightly adhering rust and scale removed. In addition, all pitting and other visible surface defects must be removed, leaving only a slightly roughened surface.
- Grade D is the most severe rust grade, with heavy rust staining and a heavy coating of loose rust and scale. To achieve the necessary level of cleaning for this Grade, the surface must be blasted to a minimum of Sa3, which is a higher level of cleaning than for the other grades. In addition, all tightly adhering rust and scale must be removed, along with any pitting or other visible surface defects. The resulting surface should be uniformly roughened with a surface profile suitable for the intended coating system.
Classes of Blast Cleaning:
AS1627.9 specifies four classes of blast cleaning for steel surfaces, including Class 1, 2, 2.5, and 3. The classes represent the level of surface preparation required, depending on the rust grade. Class 1 is the least stringent, and Class 3 is the most stringent.
