Sand Blasting Media 55 LBS Garnet #100 Grit
Brand: JRUKM
Size: 250-125 micron. Ideal for removal of mill scale, surface prep of stainless steel, aluminum, and titanium, and glass etching. Garnet grains provide a uniform surface profile with minimal embedment, supporting coating adhesion. Produces a surface profile of 1.0 – 2.0 mil or less. Blasting rates up to 330 ft2/hr. Consumption rate 1.25 – 2.0 lb/ft2.
Best for: Fabricators and refinishing projects requiring clean, uniform profiles on metals and glass.
Why selected: Excellent coating adhesion potential due to low embedment and consistent texture.
Caution: Profile and rate estimates can vary with equipment and operator technique.
SBGARN Premium Garnet Blast Media, 80 Grit
Brand: Elite Tool Center
Weight: 50 lb; Grit: 80; Material: Premium garnet abrasive.
Best for: Industrial surface prep and rust removal where a balance of aggressiveness and finish is required.
Why selected: Reliable 80-grit garnet provides consistent profiles for subsequent coatings.
Limitation: May be less aggressive than coarser meshes for heavy rust without more blasting passes.
50 LB Garnet 20/40 Mesh
Brand: Blastline
Size: 850-425 micron (20/40 mesh). Used for removal of mill scale, surface prep of stainless steel, aluminum, titanium, and glass etching. Produces a surface profile of 1.0 – 2.0 mil or less. Blasting rate up to 330 ft2/hr; consumption 1.25 – 2.0 lb/ft2.
Best for: Heavy rust and old coating removal with a robust yet finish-friendly profile.
Why selected: High-efficiency material that supports fast turnaround on larger projects.
Limitation: Coarser profile may require post-blast smoothing for delicate coatings.
55 LBS Garnet #120 Grit
Brand: JRUKM
Grit: 120; Size: 250-125 micron. Precisely targets mill scale and offers good surface preparation for stainless steel, aluminum, titanium, and glass etching. Creates a uniform surface profile with low embedment and supports coating adhesion. Production rates similar to other garnet media at up to 330 ft2/hr, consumption 1.25 – 2.0 lb/ft2.
Best for: Projects needing finer finishing with crisp coating adhesion potential.
Why selected: The finer garnet helps achieve smoother metallic surfaces without excessive material embedment.
Limitation: Finer grit can be slower on very heavy rust compared to coarser options.
50 LBS Garnet #100/120
Brand: Blastline USA
Size: 250-125 micron. Suitable for removal of mill scale and surface prep on stainless steel, aluminum, and titanium, as well as glass etching. Produces a surface profile of 1.0 – 2.0 mil or less. Rates up to 330 ft2/hr; consumption 1.25 – 2.0 lb/ft2.
Best for: Versatile option when multiple projects require a single media type with consistent performance.
Why selected: Balanced performance between material removal and finishing quality.
Limitation: Availability may vary; ensure the mesh matches your blasting equipment.
Buying Guide: Garnet Sand Blast Media
- What grit should I choose? Coarser grits (e.g., 20/40, 80) remove coatings and rust quickly but create rougher profiles. Finer grits (e.g., 100, 120) yield smoother surfaces with better coating adhesion for delicate finishes.
- Dry vs wet blasting considerations: Garnet works well in both dry and wet blasting. Wet blasting reduces dust and can improve surface cleanliness, but may require additional equipment compatibility checks.
- Surface profile and coating adhesion: Garnet grains provide uniform profiles with minimal embedment, which supports coating adhesion. If your coating system requires a precise profile, choose a garnet grit known to deliver that range (often around 1.0 – 2.0 mil or less).
- Material compatibility: Garnet is suitable for stainless steel, aluminum, titanium, glass etching, and masonry in some cases. Always verify compatibility with your substrate and coating before use.
- Blasting rate and coverage: Expect rates around 330 ft2/hr for many garnet medias, but actual performance depends on equipment, nozzle size, air pressure, and operator technique. Consider project size when selecting media.
- Cost efficiency and consumption: Media consumption often ranges around 1.25 – 2.0 lb/ft2. Higher efficiency media reduce overall usage but may cost more per bag; balance upfront cost with expected throughput.
- Safety and containment: Use appropriate PPE and dust control. Garnet is non-toxic but dust suppression reduces exposure in enclosed blasting environments.
Frequently Asked Questions
- What is garnet sand blast media best used for? It’s ideal for surface preparation, removing mill scale, and creating a uniform texture that enhances coating adhesion on metals and glass.
- How do I choose between #100 and #120 garnet? #100 provides a slightly coarser profile, good for faster cleaning; #120 gives a finer finish, better for coating adhesion and smoother surfaces.
- Can garnet be used for wet blasting? Yes, garnet is commonly used in both dry and wet blasting applications depending on equipment and project needs.
- Is garnet suitable for all metals? Garnet works well on stainless steel, aluminum, and titanium; always test a small area when working with new substrates or coatings.
- What affects blasting efficiency? Equipment pressure, nozzle size, blasting distance, and operator technique all influence efficiency and surface results.
- Are there safety considerations? Yes. Wear protective gear, manage dust, and follow local regulations for blasting operations to minimize exposure and debris.
