Avoiding Costly Mistakes: 6 Common Pitfalls When Choosing Sandblasting Media
April 22, 2025
Choosing the right sandblasting media is more than just picking the hardest or cheapest abrasive. A poor choice can lead to surface damage, higher operational costs, safety risks, or process inefficiencies. Whether you’re finishing aerospace parts or cleaning stainless steel, understanding what not to do is just as crucial as knowing what to use.
Let’s break down six critical mistakes to avoid when selecting abrasive media — and how to make smarter, performance-based decisions.

❌ 1. Ignoring the Substrate Material Specifications
Not all surfaces are created equal. Using an overly aggressive media on a soft or delicate substrate (e.g., aluminum, plastic, titanium) can cause:
- Surface gouging
- Dimensional distortion
- Post-process contamination
❌ 2. Chasing the Lowest Price
Low-cost abrasives like coal slag or silica sand may seem budget-friendly but often result in:
- High media consumption
- Dust generation and filtration overload
- More frequent media replacement
❌ 3. Overlooking Recyclability
Media that breaks down quickly may seem effective in the short term, but over time they:
- Increase waste
- Require more labor to replace
- Degrade blasting consistency
❌ 4. Mismatching Media to Equipment
Certain abrasives are incompatible with specific blasting systems. For example:
- Glass beads may clog in high-pressure wheel blast systems
- Heavy grit can wear down nozzles in suction systems
❌ 5. Neglecting Health and Safety Factors
Using silica-based or metallic abrasives without proper controls can pose risks like:
- Silicosis from airborne dust
- Heavy metal contamination
- Non-compliance with OSHA, RoHS, or REACH
❌ 6. Forgetting End-Use Requirements
A media that’s effective for cleaning may be completely inappropriate for shot peening or cosmetic finishing. Misalignment can lead to:
- Subpar adhesion or coating issues
- Unwanted surface roughness
- Poor visual aesthetics


🧠 Final Thought: Smarter Media Selection = Better Surface Results
Avoiding these common mistakes can drastically improve your blasting outcomes — from cleaner finishes and lower maintenance to improved safety and lower total costs. As blasting demands evolve across aerospace, electronics, and medical sectors, intelligent media selection becomes a strategic advantage.
If you’re unsure what media suits your application, consult with an expert supplier like Henglihong to avoid costly missteps and optimize your process from day one.
