10 Common Questions About Using Crushed Glass Media — Answered

Everything you need to know before switching to recycled glass blasting media.

Crushed glass blasting media is rapidly becoming the preferred abrasive for contractors, industrial operators, and green building projects across the USA. Yet many businesses still have questions before making the switch.

Here are the 10 most common questions about using crushed glass media — answered clearly and practically.

1️⃣ Is Crushed Glass Media Safe?

Yes. Crushed glass is silica-free and non-toxic, making it significantly safer than traditional sand blasting. It helps reduce the risk of silicosis and supports OSHA compliance.

2️⃣ Does It Produce Less Dust?

Compared to coal slag and silica sand, crushed glass generates lower dust levels when used correctly. Proper mesh selection and pressure settings further reduce airborne fines.

3️⃣ What Surfaces Can It Be Used On?

Crushed glass works effectively on:

• Structural steel
• Concrete
• Marine surfaces
• Automotive panels
• Industrial equipment

It provides strong coating removal without excessive substrate damage.

4️⃣ Is It Environmentally Friendly?

Yes. Crushed glass blasting media is made from 100% recycled post-consumer glass, diverting waste from landfills and supporting LEED projects.

5️⃣ What Mesh Sizes Are Available?

Common mesh sizes include:

• 10/20 (coarse for heavy coatings)
• 20/40 (general surface prep)
• 40/70 (lighter coatings & precision work)
• 70+ (fine finishing applications)

Selecting the right mesh improves performance and reduces dust.

6️⃣ Is It Cost-Effective?

Yes. Crushed glass offers:

• Competitive pricing
• Reduced disposal costs
• Lower health liability risks
• Efficient surface preparation

Long-term, it often reduces total project cost.

7️⃣ Can It Be Used Indoors?

Absolutely. Because it is silica-free and low-dust, crushed glass is commonly used in enclosed environments with proper ventilation systems.

8️⃣ Does It Support LEED Certification?

Yes. Its recycled content contributes toward Materials & Resources credits in LEED-certified projects.

9️⃣ Does It Damage Equipment?

No. When used correctly, crushed glass is compatible with standard blasting equipment and does not cause abnormal wear.

🔟 Is It Suitable for Sustainable Operations?

Yes. Crushed glass aligns with:

• ESG goals
• Green construction standards
• OSHA safety compliance
• Environmental responsibility initiatives

It’s one of the most practical ways to modernize your blasting process.

Final Thoughts

Crushed glass media is no longer an alternative — it’s becoming the industry standard for safe, sustainable, and efficient surface preparation.

If your business is considering the switch, understanding these fundamentals helps you make a confident decision.
