What is Shot Blasting

Shot blasting is a form of abrasive blasting that uses a pressurized stream of 'shot' (small metal or glass bits), to fulfill one of the following needs:

  • Smooth a rough/unfinished surface (note: this is different from polishing. For metal polishing, see here)
  • Shape a surface to a desired form
  • Clean a surface of exterior impurities such as burrs, oil, and rust

Shot blasting has been around since the 1800's, and has become essential to the metal and machine industry in both creation and maintenance ways.



What Type of Jobs Require Shot Blasting:

The type of job depends on the type of bead being used. For automotive shot blasting the main jobs are:

  • Rough cleaning of metal (for more intensive cleaning, see Part Washing)
  • Deburring of metal products and parts
  • Removing rust
  • Prepare surface for painting/coating

Shot blasting can also be used for rougher work such as resurfacing and refinishing concrete, as well as removing epoxies and adhesives.


Glass bead blasting is powerful enough to still remove rust and paint, but gentle enough to not harm the metal when working with vehicles. Some applications of glass bead blasting are:

  • Removing paint from vehicle
  • Giving a certain visual finish to a product
  • Remove rust from vehicle


Shot Blasting Safety:

Certain safety measures must be taken when shot blasting, despite the materials used not generally being hazardous. Some of the main hazards are:

  • Burns due to skin exposure to shot blasting
  • Falling hazard due to the loose shot potentially on the ground
  • Excessive dust (which can be inhaled)
  • Extreme noise levels

Proper equipment such as as a blast hood/helmet, proper air supply, hearing protection, and body protection.
