Beyond Sand: The Surprising Materials Used in Media Blasting

Media blasting is one of the most effective surface preparation techniques, widely used in restoration and infrastructure projects. While sand has traditionally been the industry standard, modern restoration embraces a diverse range of blasting materials tailored to specific needs. Each blasting medium offers unique advantages in terms of efficiency, safety, and application.

The Evolution of Media Blasting

Although sand was once the go-to abrasive, health, environmental, and performance concerns have driven the industry to adopt alternative blasting media. These newer materials provide more controlled cleaning, minimize surface damage, and enhance worker safety while meeting strict environmental standards.

Common Media Blasting Materials

Crushed Glass: Popular for restoration projects, crushed glass is highly effective in removing surface contaminants, paint, and corrosion while offering consistent profiling for coatings.

Baking Soda (Soda Blasting): A gentle option ideal for delicate surfaces, soda blasting removes contaminants without damaging the underlying structure. It’s widely used in fire and smoke damage restoration.

Garnet: A durable, natural mineral that delivers strong cutting power, garnet is effective for industrial applications requiring precision cleaning and surface preparation.

Steel Shot & Grit: These heavy-duty abrasives are used for aggressive cleaning, rust removal, and preparing metal surfaces for coatings. They are commonly applied in shipbuilding, structural steel, and industrial maintenance.

Plastic Media: Lightweight and reusable, plastic media is perfect for stripping paint and coatings from softer substrates like aluminum and fiberglass without damaging the base material.

Walnut Shells & Corncobs: Eco-friendly organic blasting media ideal for sensitive surfaces, offering safe cleaning options for wood, masonry, and historic preservation projects.

Factors to Consider When Choosing Blasting Media

The right media blasting choice depends on:

• Surface Condition: Level of rust, paint, or coating removal required

• Material Sensitivity: Whether the substrate is metal, wood, concrete, or fiberglass

• Project Scope: Size, timeline, and regulatory compliance requirements

• Environmental Impact: Dust control, waste disposal, and eco-friendly alternatives

• Cost Efficiency: Balancing performance and affordability for long-term use

Why Modern Media Blasting Matters

Using the right blasting media ensures optimal surface preparation, extended structural lifespan, and reduced maintenance costs. It also improves coating adhesion and helps meet environmental compliance standards.

Partnering with experienced restoration specialists ensures the best abrasive choice for your project—delivering safe, effective, and sustainable results.
