#80 Grit Aluminum Oxide Blast Media
The TITGGI #80 grit aluminum oxide blast media offers high hardness and a long cycle life, making it suitable for fast rust removal and etching on glass, metal, and stone. While not silica, its performance is notable for surfaces requiring aggressive blasting. It can be used in both dry and wet applications and is marketed as eco-friendly due to recycled content. This media is particularly effective where rapid material removal is needed, though care should be taken with softer substrates to avoid excessive etching.
#120 Grit Aluminum Oxide Sandblasting Medium
Striplus offers a 120-grit aluminum oxide medium with 99.5% purity, designed for professional sandblasting cabinets and machines. The sharp, angular grains deliver fast rust and coating removal, leaving an even satin finish on metal and other surfaces. It is reusable for multiple cycles (approximately 6–8), which can reduce per-job costs. As a non-silica option, it provides a clean alternative when silica-containing media are a concern, though performance differs from silica sands on certain substrates.
Teton Supply Co. Pure Silica Sand, 120 Mesh
Pure silica sand at 120 mesh is kiln-dried and designed for high-temperature performance. Teton’s media is intended for foundries and professional applications where consistent particle size and purity matter. Silica-based blasting can achieve predictable profiles on metal, glass, and ceramic surfaces, making this a standard choice for controlled blasting operations. Users should follow safety guidelines due to silica inhalation risks and ensure proper protective equipment is worn during use.
Applied Technologies Dry Silica Sand
Applied Technologies offers a dry ground silica sand designed for versatile use, including floor crack repairs and thickening materials for heavy bodies. This product is positioned for construction and repair applications where silica sand serves as a base component. When used for blast cleaning, it can provide a balanced profile suitable for coatings preparation and rust removal, with emphasis on achieving stable, consistent results in mixed-media projects.
U.S. Silica Play Sand
U.S. Silica plays sand is a soft, finely graded, washed product designed for safe, child-friendly use, but it also serves well for certain blasting tasks that require a gentle, fine substrate. The washed and screened texture reduces debris and dust, contributing to a cleaner blasting environment. While not a heavy-duty blasting media, it offers a low-dust option for lighter surface prep and finishing work on delicate substrates.
Sandblasting Media Glass Beads #10
Roly Poly glass beads are a silica-free option consisting of soda-lime glass. They provide a less aggressive, satin-finishing blast suitable for softer metals and delicate components where a shiny, even texture is desired without deep etching. The media is reusable and recyclable, helping reduce waste. It is ideal for cleaning, deburring, descaling, and preparing surfaces for coatings without introducing silica-related health concerns.
Buying Guide: Key Purchase Considerations
- Material composition: Silica sands are common for aggressive cleaning and etching, but glass beads and oxide media offer alternative finishes and safety profiles. Consider whether silica exposure concerns are a priority.
- Particle size and mesh: Finer grades (e.g., 120 mesh) yield smoother finishes, while coarser grades remove material faster but may roughen surfaces. Match particle size to the intended surface and coating.
- Purity and contaminants: Higher purity reduces impurities that can affect coatings or surface reactions. Kiln-dried silica sands are often preferred for high-temp applications.
- Reuse and lifespan: Reusability lowers total cost. Media with higher hardness typically lasts longer but may require more robust blasting equipment.
- Safety and handling: Silica-based media can pose inhalation risks. Use appropriate respiratory protection, ventilation, and wet blasting where applicable.
- Application suitability: For metal surfaces, consider media that both cleans rust and provides an appropriate profile for coatings. For glass or stone, choose media that minimizes surface damage.
