What is Abrasive Blasting? A Comprehensive Guide

Abrasive blasting, is a technique used to clean, smooth, or shape surfaces by propelling abrasive materials at high speeds.

This method is widely used across various industries, including engineering, aerospace, and manufacturing, due to its efficiency and versatility.

In this comprehensive guide, we’ll explore what it is, the types of abrasive materials used, the different techniques used, and the benefits it offers. In addition, we will discuss how SurfacePrep UK can assist you in achieving the best results with abrasive blasting.

Understanding Abrasive Blasting

Abrasive blasting involves using a stream of abrasive material directed at a surface under high pressure. This process effectively removes unwanted contaminants, rust, paint, or coatings, leaving a clean and smooth surface behind. The technique is particularly useful for preparing surfaces for painting, coating, or bonding.

Types of Abrasive Materials

1. Glass Bead: Ideal for peening and cleaning surfaces without causing damage.
2. Steel Grit: Used for aggressive cleaning and surface preparation, especially for removing paint and rust.
3. Aluminium Oxide: A durable abrasive used for preparation, finishing and polishing.
4. Garnet: Used for a cleaner application than traditional expendables with improved cutting performance and low to tendency for embedment. Used in surface preparation and surface finishing.
5. Plastic Media (Avialite Type II, III, V): Gentle abrasives used for cleaning softer surfaces without causing damage. Used in the automotive and aerospace industries.

Techniques of Abrasive Blasting

1. Abrasive Blasting (Dry): Uses compressed air to propel abrasive material, suitable for tougher cleaning and surface preparation tasks. This technique is versatile and widely used in various industries.
2. Wet Abrasive Blasting (Wet): Combines water with abrasive material, reducing dust and heat generated during the process. The process is  used for delicate surfaces and environments where dust suppression is essential.
3. Vacuum Blasting: Incorporates a vacuum system to recover the abrasive material and debris, making it ideal for confined spaces and reducing clean-up time.

Benefits of Abrasive Blasting

• Efficiency: It quickly and effectively removes contaminants, such as rust, paint and other coatings from the surface. It’s advantages are that it saves time compared to manual cleaning methods and improves productivity.
• Versatility: It can be used on a variety of materials, including metal, concrete, wood, and plastic. Making it suitable for various applications and industries.
• Surface Preparation: Creates a clean and roughened surface to a specific profile, ideal for improving the bond of paints, coatings, and adhesives.
• Precision: Allows for targeted cleaning and surface preparation, ensuring only the desired areas are treated.
• Cost-Effective: Reduces labour costs and time required for surface preparation and cleaning, making it a cost-effective solution for many industries.

Safety Considerations

While abrasive blasting is highly effective, it presents potential health and safety risks. Proper protective equipment, including respirators, gloves, and eye protection, is essential to safeguard workers from inhaling dust and exposure to hazardous materials. Additionally, ensuring proper ventilation and dust collection systems can help minimise risks in the workplace.

*Blasting with sand, was made illegal in the UK in 1950. The use of sand in abrasive blasting was prohibited due to the significant health risks it poses, particularly the development of silicosis, a serious lung disease caused by inhaling fine silica dust. Therefore, sand should not be used in this process.
