Media sandblasting is a versatile technique used to clean, restore, and prepare surfaces across various industries. Choosing the right type of abrasive media is crucial to achieving the desired results, ensuring efficiency and surface protection.
What is media sandblasting?
Media sandblasting uses abrasive materials, or media, to clean, strip, or prepare surfaces. This technique is widely used in industries such as construction, automotive restoration, and manufacturing.
By propelling abrasive particles at high speed, sandblasting removes rust, paint, and debris, leaving surfaces ready for finishing treatments such as painting or coating. The choice of media plays a critical role in achieving the desired outcome, whether gentle cleaning or aggressive surface preparation.
Applications of media sandblasting
Beyond cleaning, media sandblasting is essential for preparing surfaces for treatments such as thermal plasma spray coatings. It improves adhesion, enhances durability, and ensures a smooth finish.

Common types of sandblasting media
- Soda
Soda blasting uses sodium bicarbonate to clean surfaces without causing damage. Its non-abrasive nature makes it ideal for delicate tasks, such as removing rust from thin metal layers.
- Crushed glass
Made from recycled glass, crushed glass grit is eco-friendly and effective for surface profiling and removing coatings. Its angular shape ensures precision, while its non-toxic nature reduces health risks for operators.
- Aluminium oxide
Aluminium oxide grit is a sharp, long-lasting abrasive commonly used for heavy-duty applications such as surface etching and preparation. It is particularly effective for metals and can be recycled multiple times, offering both durability and cost-efficiency.
- Walnut shells
Walnut shell grit provides a softer, biodegradable option for cleaning delicate surfaces. It is often used for tasks such as stripping paint from wood or cleaning aircraft components without damaging the underlying material.
Choosing the right media
Selecting the appropriate media depends on several factors, including the surface material, the level of abrasion required, and environmental considerations. Certain coatings may require surface preparation with aluminium oxide or crushed glass grit, depending on the application.
