The Key to Better Surface Preparation — Tailored Mesh for Every Job
When it comes to abrasive blasting, using the right glass blasting media mesh size can make all the difference. Whether you’re stripping paint, cleaning delicate surfaces, or preparing steel for coating, the correct mesh ensures:
✅ Higher efficiency
✅ Better surface finish
✅ Lower media consumption
✅ Reduced cleanup and downtime
In this guide, we’ll walk you through everything you need to know about mesh sizes, how they work, and how to choose the best one for your specific application.
What is Mesh Size in Blasting Media?
Mesh size refers to the number of openings per linear inch in a screen used to classify particle size. For example:
Mesh 20: Particles pass through a screen with 20 openings per inch.
Mesh 80: Much finer — more particles per inch = smaller grit size.
The higher the mesh number, the finer the abrasive.
Common Mesh Sizes in Glass Blasting Media
At Zafa Glass, we offer a full range of mesh sizes to suit diverse industrial needs:
| Mesh Size | Micron Range | Common Use |
|---|---|---|
| 10/20 | 850–2000 µm | Heavy coating/paint removal, surface profiling |
| 20/40 | 425–850 µm | Rust removal, general blasting |
| 40/70 | 212–425 µm | Light mill scale, softer metals |
| 70/100 | 150–212 µm | Polishing, etching, light surface cleaning |
| 80+ | <180 µm | Decorative finishes, glass/ceramic etching |
How to Choose the Right Mesh Size
1️⃣ Understand Your Substrate
Steel & Concrete: Use coarser mesh like 20/40 or 40/70.
Glass, Aluminum, or Delicate Surfaces: Choose finer media like 70/100 or 80+.
2️⃣ Match the Application
Coating Removal / Profiling: Mesh 10/20, 20/40
Rust / Mill Scale Cleaning: Mesh 40/70
Fine Cleaning / Etching: Mesh 70/100, 80+
3️⃣ Balance Speed and Finish
Coarse Mesh: Faster cutting, rougher finish
Fine Mesh: Slower cutting, smoother finish
Choose based on the level of detail or aggressiveness required.
Why Mesh Size Impacts Efficiency
Using the wrong mesh size can result in:
❌ Inconsistent surface finish
❌ Poor coating adhesion
❌ Excessive media waste
❌ More cleanup effort
On the other hand, the right mesh:
✅ Cuts faster
✅ Lasts longer
✅ Improves visibility
✅ Lowers overall cost
Industries That Rely on the Right Mesh
Shipbuilding & Marine Blasting
Oil & Gas Infrastructure
Aerospace Surface Prep
Automotive Restoration
Glass & Art Etching
Each industry demands a specific surface profile, and that comes down to mesh accuracy.
Final Thoughts
Glass blasting media mesh size is not one-size-fits-all.
✅ A fine mesh gives you precision
✅ A coarse mesh gives you power
✅ The right one gives you both performance and efficiency
Make every blasting project cleaner, faster, and safer with mesh sizes tailored to your exact needs.
