How Much Sand Do You Need for Sandblasting? A Real Test with the LEMATEC AS118-2C

One of the most frequently asked questions: "How much sand do I need for sandblasting?" In this test, we used the LEMATEC AS118-2C Dual Feed Sandblaster with Aluminum Oxide #46 to remove paint from a wooden surface. This real-world demo will help you estimate how much abrasive media you need for similar projects.

🔹 Testing Conditions & Setup

  • Sandblaster Used: LEMATEC AS118-2C (Dual Feed System)
  • Sandblasting Media: Aluminum Oxide #46
  • Surface Material: Painted Wooden Board
  • Air Compressor Setting: 90 PSI
  • Estimated Coverage Area: Full wooden panel

🔹 How Much Sand Was Used?

We used approximately 5 kgs of Aluminum Oxide #46 during this test. This can vary depending on:

  • Abrasive Type – Harder abrasives last longer but may consume more air.
  • Air Pressure – Higher PSI removes coatings faster but consumes more media.
  • Nozzle Distance & Angle – Closer distances can improve efficiency.

🔹 Key Takeaways from This Test

  • 💡 Estimate Your Media Needs: Stripping paint from wood.
  • 💡 Choose the Right Sandblaster: The LEMATEC AS118-2C offers dual feed options for better efficiency.
  • 💡 Optimize Your Setup: Adjusting PSI, nozzle distance, and sand type can save time and reduce material waste.

🔹 Common Sandblasting Applications

Sandblasting isn’t just for paint removal! Here are other ways you can use it:

  • Rust Removal: Restore metal parts with ease.
  • Surface Preparation: Ensure proper paint adhesion.
  • Glass Etching: Create custom designs on glass.
  • Industrial Cleaning: Remove dirt and corrosion from heavy machinery.

🔹 Recommended Sandblasting Media

  • Aluminum Oxide – Best for tough paint & rust removal.
  • Glass Beads – Ideal for smoothing and polishing.
  • Silicon Carbide – Best for aggressive stripping.
  • Walnut Shells – Eco-friendly option for delicate surfaces.
