What is Abrasive Blasting?

Abrasive blasting is a process that involves propelling abrasive particles at high speeds onto a surface to clean, roughen, or shape it.  This technique is widely used in various industries, such as construction, automotive, marine, and aerospace.  It can be used for various applications, from preparing surfaces for painting or coating to removing rust, old paint, or other unwanted coatings.

There are various types of abrasive blasting methods, including sandblasting, steel grit blasting, and crushed glass blasting.  Each method has unique properties and is best suited for specific surfaces and applications.  For example, steel grit blasting is often used for heavy industrial plant and equipment, marine vessels and structures, truck bodies, or trailers.  At the same time, crushed glass is more commonly used for lighter steels, galvanized steel, stainless steel, or aluminium.

Benefits of Abrasive Blasting:
Abrasive blasting offers several benefits for industrial applications, including:

1. 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.

2. Cost-effective:

   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.  By removing rust and coatings, abrasive blasting helps to prevent further corrosion and damage, which can lead to costly repairs or replacements.  Regular maintenance through abrasive blasting can help to extend the life of equipment and structures, resulting in significant cost savings.

   At Neumann Industrial Coatings, we understand the importance of cost-effectiveness in surface preparation.  That’s why we offer a variety of abrasive blasting services that are tailored to each client’s specific needs and budget.  Our team of experienced professionals uses state-of-the-art equipment and techniques to ensure that every job is done efficiently, effectively, and within budget.  We also offer competitive pricing and flexible scheduling to accommodate even the most demanding projects.  With our abrasive blasting services, our clients can be confident they are getting the most cost-effective solution for their surface preparation needs.

3. Environmentally friendly:

   Abrasive blasting is also environmentally friendly due to the fact that it is a dry process that produces no harmful chemicals or waste products.  Unlike traditional cleaning methods that use chemicals or solvents, abrasive blasting relies solely on the use of an abrasive media and air pressure.  This means that there is no need for any harmful chemicals or solvents to be used, reducing the risk of environmental pollution.

   Furthermore, abrasive blasting can be performed with recycled abrasives, such as crushed glass or steel grit, reducing the need for new materials and minimizing waste.  At Neumann Industrial Coatings, we use 100% recycled crushed glass media in our blasting services, reducing waste and costs for our clients.

   Another environmentally friendly aspect of abrasive blasting is that it removes surface contaminants, such as rust and paint, from metal surfaces, allowing for proper disposal and preventing the release of pollutants into the environment.  This is especially important when working on marine vessels or equipment that may be in contact with water, as the removal of rust and other contaminants prevents the contamination of waterways.

   Finally, abrasive blasting is also more efficient than other cleaning methods, which can take longer and require more energy and resources.  The efficiency of abrasive blasting means that less energy and resources are required to complete the job, further reducing the environmental impact of the process.

   Overall, abrasive blasting is an environmentally friendly option for surface preparation and cleaning that reduces waste, eliminates the use of harmful chemicals, and is more efficient than other methods.

Removing Rust, Restoring Life

Introduction:
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.

Rust Grades:

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.

• Class 1: Light Blast Cleaning
  Class 1 requires the removal of loose rust, mill scale, and other surface contaminants.  The surface should have a minimum of 95% of the original surface profile.  This class is suitable for surfaces with Grade A rust.
• Class 2: Thorough Blast Cleaning
  Class 2 requires the removal of all visible rust, mill scale, and other surface contaminants.  The surface should have a minimum of 100% of the original surface profile.  This class is suitable for surfaces with Grade B and C rust.
• Class 2.5: Very Thorough Blast Cleaning
  Class 2.5 is an intermediate class between Class 2 and Class 3.  This class requires the removal of all visible rust, mill scale, and other surface contaminants.  The surface should have a minimum of 125% of the original surface profile.  This class is suitable for surfaces with Grade B and C rust, requiring higher surface preparation.
• Class 3: Near-White Blast Cleaning
  Class 3 is the most stringent surface preparation level, requiring removing all visible rust, mill scale, and other surface contaminants.  The surface should have a minimum of 95% of the original surface profile.  This class is suitable for surfaces with Grade C rust, where the surface needs to be prepared for high-performance coatings.
