What’s the Best Sand for Sandblasting?

Sandblasting Materials

• The most commonly used sandblasting sand is silica sand. Silica sand is primarily used because it has good quality, durability, and availability.
• Other sandblasting materials include: glass beads, aluminum oxide, silicon carbide, crushed walnut shells. The material depends on the task.
• For example, softer beads for delicate surfaces. Reusable materials like aluminum oxide reduce cost.

Choosing Sand Type for Sandblasting

• Silica sand was used in the past for sandblasting. This caused lung disease in sandblasters from inhaling silica dust. Now sandblasting with sands containing >1% free silica is forbidden.
• Finer sands remove lighter materials like paint. Coarser sands remove heavier materials like rust.
• The grit size needed depends on the job. Safety gear is essential during sandblasting due to the high pressure stream and dust created.

Using Beach Sand in Sandblasting

• Can I use beach sand in my sandblaster?
• Other sandblasting materials include: glass beads, aluminum oxide, silicon carbide, crushed walnut shells. The material depends on the task.
• Reusable materials like aluminum oxide reduce cost. Finer sands remove lighter materials like paint. Coarser sands remove heavier materials like rust.
