  • Hardness: Garnet ranks around 6.5 to 7.5 on the Mohs scale, making it a highly effective cutting and blasting material.

  • Chemically Inert: It does not react with most chemicals, making it safe for use in a wide range of applications.

  • Recyclable: Garnet can often be reused multiple times depending on the application and the level of contamination.

Blasting Garnet Abrasive are scientifically formulated to work together on delicate restoration projects. Cleaning valuable historic assets, masonry, concrete, grout, stone, marble, tile and much more, Garnet is a cost-effective, high-performance, environmentally friendly abrasive. The perfect symbiosis of grain size, density and hardness/durability creates the optimum abrasive efficiency and lowest abrasive consumption. It can be recycled 5 times without losing it’s superior ability. Low dusting improves health and safety for the operator and the environment.

Common Applications:

    Waterjet Cutting: Garnet is the most popular abrasive used in waterjet cutting machines due to its sharp edges, hardness, and clean performance.

    Sandblasting (Abrasive Blasting): Used to clean surfaces like steel, concrete, and other materials. Garnet is favored because it produces minimal dust and is environmentally friendly.

    Abrasive Papers: Used in sandpapers for wood, metal, and other material finishing.

    Filtration Media: Garnet is also used in water filtration systems due to its density and durability.

Performance Characteristics

  • High Hardness: It ranks 7.5 to 8.0 on the Mohs hardness scale. Its tough, sub-angular to angular crystalline structure allows it to aggressively cut through thick coatings, rust, and mill scale.
  • High Density: It features a high specific gravity (approx. 4.1), meaning the grains hit surfaces with greater kinetic energy, accelerating the blasting process.
  • Low Dust Generation: Because it is highly durable, garnet fractures cleanly rather than shattering into a fine powder upon impact. This results in excellent visibility for the blaster and vastly reduced clean-up times.
  • Recyclability: Unlike single-use slags, high-quality garnet can be collected, screened, and reused 4 to 6 times before losing its cutting efficiency, significantly driving down total project costs.

Major Advantages & Safety

  • Silica-Free: Garnet contains virtually no free silica, eliminating the risk of silicosis (a major respiratory hazard associated with traditional sand).
  • Non-Toxic: It is an inert, natural mineral that is non-hazardous and free of toxic heavy metals, making it safe for open-air, marine, and environmentally sensitive projects.
  • No Surface Embedment: It leaves a exceptionally clean anchor profile that is free of rogue peaks or embedded grit, ensuring maximum adhesion for new industrial coatings and paints.

Common Mesh Sizes and Grits

  • Coarse (20/40 or 30/60 Mesh): Used for heavy-duty industrial blasting. Ideal for removing thick ship hull marine coatings, multi-layered industrial paint, and heavy rust from structural steel.
  • Medium (60 Mesh / 80 Mesh): The most versatile range. Frequently used for Dustless Blasting systems or dry setups to clean aluminum, remove mill scale, prepare new steel fabrications, and clean automotive panels without warping the metal.
  • Fine (120+ Mesh): Utilized for precision etching, delicate graffiti removal, architectural concrete cleaning, and hydro-blasting systems where a smooth surface finish is critical.
