Choosing the Right Abrasive for Your Sandblasting Project: A Guide

Selecting the ideal abrasive is crucial for achieving stunning results in your sandblasting projects. With various options available, understanding their specific strengths and applications is key. Here's a breakdown of Crystal Galleries' white aluminium oxide abrasives to help you make the right choice:

Fine Detailing

  • 20k 180 White Abrasive & 10k 180/220 White Abrasive: These finer grades excel in producing high-detail designs, fine lines, and halftone effects. Perfect for intricate work on glass, stone, wood, and other materials. Ideal for use with 2 mil or thicker photoresist films.

Moderate Detailing & Versatility

  • 20k 280 White Abrasive & 10k 280/320 White Abrasive: These mid-range grades offer a balance between detail and speed. Suitable for creating clean lines, lettering, and moderate depth etching. They work well with both photoresist films and Crystal Galleries' SelfAd self-adhesive tissue stencils.

Deep Etching & Rough Textures

  • 20k 150 White Abrasive & 10k 150 White Abrasive: These coarser grades are designed for deep carving and heavy-duty tasks. Ideal for projects requiring significant material removal on glass, ceramics, stone, and wood. They are best suited for thicker photoresist films (5 mil or above).

Key Takeaways

  • Grit size: Higher numbers indicate finer grades for delicate work, while lower numbers are coarser for deep etching.

  • Application: Match the abrasive to your desired detail level and material thickness.

  • Compatibility: Ensure compatibility with your chosen photoresist films or stencils.
