deccan garnet

Deccan Garnet

Garnet is a sandblasting mineral, derived from either Almandite or Andradite deposits. It is inert natural mineral and varies from pink to reddish brown colour. This is an industrial gemstone that creates a profile virtually free of embedment. Which makes it excellent for coating adhesion, as well as applications where low or no transfer of grit into the substrate can be tolerated. This is a hard, heavy, durable abrasive. It can be recycled up to 5 times without a loss in performance. It can be used for cleaning steel in various applications including ship building and repair, tanks, offshore platforms, and pipelines. It is also used to provide surface finish for powder coaters.


Deccan Garnet is uniform with specifications, High hardness of 8 MoH and very High specific gravity 4 gm/cc make it unique . With very low chloride content make the life of the coating at least double which in long term advantage . Deccan Garnet has almost nil free silica which made very  safe for the environment and loss on ignition as low as 0.05% gifted by nature.

Grade 12/20

Advantages of Deccan Garnet

High performance, low dust abrasive
Uniform and superior surface profile
Ideal for industrial coating work with a selection of grades to suit various applications. e.g. new steel, whip blasting, full blasting, heavy rust removal, feathering, etc.
Economical, single use abrasive
Non toxic – inert and natural, crystalline silica levels are less than 1%
May also be recycled.


The hardness and density of garnet combine to create a highly efficient cutting action with minimal dust emissions and confined fallout of used abrasive. The scouring action of the relatively fine grains clean out pitted areas giving the highest degree of surface cleanliness whilst producing an even textured profile of between 65 and 75 microns.


Deccan garnet is totally inert offering no danger of environmental or marine pollution.Due to the low dust levels, operator visibility is greatly improved and other trades working in close proximity remain unaffected. Quantities of used abrasive which may contain contamination removed from the substrate by the blasting process, will be dramatically reduced thus minimising waste disposal problems.
