Sand Blasting Media 55 LBS Garnet #100
Features include a fine to medium particle size (250-125 micron) designed for effective removal of mill scale and surface preparation on stainless steel, aluminum, and titanium. Garnet grains provide a uniform surface profile, promoting coating adhesion with minimal embedment. Typical surface profile ranges from 1.0 to 2.0 mils. Blasting rates can reach up to 330 ft2/hr, with a consumption rate between 1.25 and 2.0 lb/ft2. This makes it suitable for both precision coating prep and glazing effects on glass when desired.
50 LB Garnet 20/40 Mesh
This medium-coarse garnet is suitable for both wet and dry blasting, providing a uniform surface profile with minimal embedment for strong coating adhesion. The 20/40 mesh size is effective for rust removal, heavy coating stripping, and preparing surfaces for high-build coatings. The media is described as high-build efficient, capable of sustaining robust blasting performance, and it supports applications requiring both rust removal and surface cleaning on various metals.
50 LBS Garnet #100/120
Fine to very fine garnet blend (#100/120, 250-125 micron) is optimized for precise surface preparation on stainless steel, aluminum, and titanium, including glass etching where needed. This media yields a surface profile typically between 1.0 and 2.0 mils, supporting good coating adhesion. Blasting rates are similar to other garnet grades, with practical consumption around 1.25 to 2.0 lb per square foot, making it suitable for detailed restoration projects and equipment maintenance requiring careful material removal.
10 LBS Garnet #100/120
Small-batch garnet media with the same fine #100/120 grading supports controlled surface preparation, ideal for hobby projects or spot-treatment on critical components. The small bag size is convenient for intermittent blasting tasks, ensuring precise material management. This grade provides reliable surface cleaning and etching without over-roughening the substrate, and it performs well for delicate finishes on stainless steel, aluminum, and glass.
Garnet #60 – Medium Grit
Garnet #60 is a medium grit option noted for its sharpness and high quality. Made in the USA, it’s well-suited for aggressive paint removal, metal refinishing, and etching rock surfaces. The double-washed crushed Almandine garnet provides dependable performance with strong surface cleaning capabilities, making it a solid choice for contractors and metalworking shops seeking a durable blasting media for larger-scale tasks.
Garnet Abrasive Media GritWorks 40LBS
GritWorks offers a natural garnet composition with less than 1% free silica, reducing health and safety concerns in industrial use. The media is versatile for conditioning and finishing various materials, enabling cleaner, smoother, or rougher surface textures as needed. The high-pressure blast capability allows precise control for etching, smoothing, or texturing, making it suitable for multi-material projects and refurbishing operations.
Buying Guide: Key Considerations For Garnet Blast Media
When choosing garnet blasting media, several factors influence performance and cost-efficiency. Consider the following perspectives to ensure you pick the right grade for your project:
- Grit size and texture: Finer grades (#100/120) suit precision work and coating adhesion, while coarser grades (#60) offer faster material removal and rougher textures for heavy coatings.
- Application type: Dry blasting versus wet blasting can affect dust generation and cleanup. Wet blasting generally produces less dust and can improve surface finish for certain coatings.
- Surface material: Stainless steel, aluminum, titanium, and glass each respond differently to garnet profiles. Check manufacturer recommendations for surface preparation and compatibility.
- Coating compatibility: For coatings requiring strong adhesion, aim for a uniform surface profile in the 1.0–2.0 mil range. Ensure the media’s hardness supports this without excessive embedment.
- Cost and packaging: Larger bags (e.g., 50–55 lbs) offer lower cost per pound but require more storage and space. Smaller packs are convenient for intermittent use or small jobs.
- Health and safety: Garnet is considered relatively safe, but proper PPE and dust control are essential. Look for media with low silica content and follow ventilation guidelines.
- Availability and sourcing: Consider brands with consistent particle size distribution and wash quality. USA-made options may offer stricter quality control for industrial applications.
Comparing the five highlighted garnet products shows a balance between finer and mid-range grit, packaging sizes, and brands. The JRUKM and Blastline USA lines emphasize uniform surface profiles and coating readiness, while Tacoma Company offers a USA-made option with reliable performance for paint removal and metal finishing. For precise, detail-focused work, the #100/120 grades are typically preferred, while #60 provides more aggressive material removal. Always verify the intended surface material and coating requirements before blasting.
