How Much Sand Do You Need for Sandblasting? Real Test with LEMATEC AS118-2C
How Much Sand Do You Need for Sandblasting?
A Real-World Media Consumption Test
One of the most frequent questions we receive from professionals and DIYers is: "How much media will my project consume?" To provide a concrete answer, we conducted a standardized paint-stripping test using the LEMATEC AS118-2C.
🔹 Testing Conditions & Setup
Model UsedAS118-2C Dual Feed
Media TypeAluminum Oxide #46
Target SurfacePainted Wooden Panel
Air Pressure90 PSI (Constant)
~ 5 KGS
Abrasive media are used to strip the full test panel
*Consumption varies based on nozzle distance, material hardness, and air pressure stability.
💡 Key Insights for Media Estimation
- Harder abrasives last longer through multiple cycles but may consume more CFM if not regulated correctly.
- High PSI (90+) removes coatings faster but increases media breakdown rate (dust creation).
- Nozzle Proximity: Maintaining a 5-10cm distance maximizes kinetic energy transfer and reduces media waste.
🔹 Recommended Media by Application
Aluminum Oxide Heavy-duty paint and thick rust removal. Very durable.
Glass Beads Perfect for smoothing, polishing, and satin finishes.
Silicon Carbide Aggressive stripping on very hard metal surfaces.
Walnut Shells Eco-friendly stripping for delicate wood or fiberglass.
