How to choose the correct abrasive for your sandblasting process?

To understand the how well, we need to understand well what is sand blast or sandblasting? The definition of this word is understood as “sand under pressure”; however, numerous abrasives in addition to sand can be used in this operation to clean, polish or remove materials and residues from different surfaces.

In areas of abrasives, we have 2 types commonly used:


  • Aluminum oxide
  • Steel shot
  • Silicium carbide
  • Sodium bicarbonate
  • Cut wire
  • Garnet
  • Copper slag
  • Glass pearl
  • Plastic abrasive


  • Silica sand
  • Diamonds
  • Quartz
  • Corundum


To sandblast, we use compressed air which propels the abrasives at high speed, causing the residues to come off when they hit the surfaces.

This technique is generally used on steel, castings and different metal alloys, although it can also be applied on glass, wood, slabs, marble, acrylics, which makes it a great option for metalworking, automotive, railway, even construction applications. In certain cases it could be applied in mining and agriculture since its purpose is to clean surfaces, make them more resistant and protect them from oxidation as well as remove impurities, paints, resins and more, with this technique you can give a second life to your machinery, your equipment or spare parts.

Understanding this, we can conclude that an abrasive should be chosen taking into account 2 main things: the material with which we are going to work and the type of application that this material needs.

Therefore, if our materials are soft, we must implement coarse-grained abrasives such as our G14 to G25 or S660 to S330 shot sizes, this is implemented when the finish is not really important, fine-grained abrasives are ideal for use. on fragile or brittle materials and to achieve a much finer or specific finish for paint or coatings, for this we have the grits ranging from G40 to G80 or S390 to S660.

If we want to grind, sharpen or polish, we must use agglomerated abrasives and if we have an application on non-ferrous parts, we can use more specialized abrasives such as stainless steel shot.
