Applied Technologies Dry Silica Sand
Product: Applied Technologies Dry Silica Sand- 4 lb Bag
Brand: Applied Technologies
Features: Dry ground silica sand, Mix with floor crack repair products such as A-Tech 1300, Thickens materials for heavy body
Relevance: This product is a direct silica sand option, suitable for projects that require silica-based blasting media or filler in repair scenarios. While not all blasting kits are designed for pure blasting use with 4 lb bags, silica sand remains the most common blasting media for certain light-duty tasks and finishing steps on metal, glass, and stone. Consider dust control and respirator use when handling silica sand to reduce fine particle exposure.
U.S. Silica Mystic White II Sand
Product: U.S. Silica Mystic White II Sand for Above Ground and Inground Pool Filter Pumps, 50 Lb
Brand: U.S. Silica
Features: High-Quality Filtration; 50 pounds of high-purity white silica sand; Effective pool filtration with consistent sizing; Easy to store and handle
Relevance: Though marketed for pool filtration, this silica sand type is representative of high-purity silica particles and can offer a baseline for comparison with blasting-grade silica. Safety and dust considerations are important, and compatibility with blasting equipment should be verified before use in blasting contexts.
#80 Grit Aluminum Oxide Blast Media (TITGGI)
Product: #80 Grit Aluminum Oxide Blast Media (8 LBS/3.6kg) – Premium Long-Lasting Sand Blasting Media
Brand: TITGGI
Features: High hardness (Mohs 9), long-lasting, eco-friendly with no free silica; can be used wet or dry; suitable for metal, glass, stone, and ceramic surfaces
Relevance: Aluminum oxide is a popular blasting media alternative when silica exposure is a concern. Its hardness enables effective rust removal and surface preparation, with a longer cycle life than silica in many cases. Use proper PPE and ensure compatibility with your blasting system.
#80 Grit Aluminum Oxide – 8 Oz (Ninesung)
Product: #80 Grit Aluminum Oxide – Sandblasting Media Premium Long-Lasting
Brand: ninesung
Features: High hardness; long-lasting; eco-friendly; non-reactant; suitable for glass, granite, marble, ceramic, steel
Relevance: A compact option that demonstrates the same material family as TITGGI media. Useful for smaller jobs or practice runs where you want predictable results without silica exposure concerns.
#100 Grit Aluminum Oxide Blast Media (TITGGI)
Product: #100 Grit Aluminum Oxide Blast Media (19LBS/8.6kg)
Brand: TITGGI
Features: High hardness; long-lasting; eco-friendly; 100% recycled media; versatile for metal, glass, wood, stone
Relevance: This heavier-weight aluminum oxide option supports aggressive blasting and extended use in metal prep. It provides robust cleaning and finishing with less breakage than some alternatives, making it suitable for larger projects.
#120 Aluminum Oxide for Blasting
Product: #120 Aluminum Oxide – 50 LBS or 22.6 kg
Brand: INTERACTIVIA
Features: Harder than most blasting media; cleans and etches all surfaces; no detectable crystalline silica; lasts 10 times longer than silica
Relevance: A larger bag with finer grit suitable for detailed surface prep and smoother finishes. The absence of silica reduces respirable silica concerns, but still requires standard blasting safety practices.
Buying Guide: Key Purchase Considerations
- Material composition and safety: Silica sand can pose inhalation risks; consider silica-free alternatives like aluminum oxide for higher hardness and reduced silica exposure. Verify respirator requirements and dust controls in your blasting area.
- Abrasive hardness and finish: Hard media such as aluminum oxide (Mohs ~9) is effective for rust removal and etching on metal, glass, and stone. Softer media or coarser grits may be better for delicate surfaces or heavy surface prep, respectively.
- Particle size and grit: Finer grits (e.g., #120) produce smoother finishes but less aggressive cleaning, while coarser grits (e.g., #80) remove material faster. Choose grit based on surface type and desired finish.
- Durability and lifecycle: Long-lasting media reduces replacement frequency and cost. Media like aluminum oxide typically outlasts silica-based options, especially in repeated blasting cycles.
- Environmental and dust considerations: Silica-free options reduce hazardous dust. Look for media with lower respirable silica risk and check if the media is reusable or requires disposal after use.
- Compatibility with equipment: Ensure the chosen media size matches your blast cabinet, nozzle, and compressor specifications. Some media types require specific air pressures or nozzle geometries for optimal results.
- Application scope: For metal rust removal and coating prep, hard media is often preferred. For glass etching or soft wood finishing, gentler media or wet blasting methods may be better.
- Storage and handling: Silica sand needs careful storage to minimize dust. sealed containers and proper ventilation help maintain a safe workspace.
In sum, silica-based blasting media remains common for many applications, but aluminum oxide offers strong alternative performance with lower silica exposure. Evaluate your project requirements, safety needs, and equipment compatibility when selecting a blasting media. The products listed here provide a range of silica and silica-free options to suit different surfaces and blasting goals.
