It is an efficient way of removing foreign elements from almost any surface. Hartech Pty Ltd specialises in all forms of abrasive blasting, also popularly known as sandblasting or grit blasting.

Corrosion is inevitable and impacts the strength of metal, damaging it significantly. National Association of Corrosion Engineers (NACE) defines corrosion as a “naturally occurring phenomenon” resulting from the reaction of metal surfaces with the external environment, leading to rust formation and its weakening.

Sandblasting is a way of removing this rust effectively. However, merely plastering a layer of coating over the rusted surface will not prevent further damage. It is of utmost importance to remove the rust underneath to ensure no further rust oxidation occurs.

Abrasive Blasting Explained

Abrasive blasting is the process of forceful thrusting of a high-pressure blast of abrasive material (bead, water, dry ice etc.) on a metallic surface. It is aimed at:

  • Smoothening rough surfaces or vice versa
  • Removing foreign matter from the surface


Grit or sandblasting is the preferred rust removal method of choice by corrosion experts for many reasons, some of which are enlisted below.

  • It leaves the surface unscathed while successfully removing contaminants.
  • Sandblasting can address corrosion and remove rust from the remotest of corners like concrete parking garages or insulated corroded metal elements.
  • It enables targeted removal of corrosion eliminating the need for recoating the entire element surface.
  • It prepares the surface for powder coating, thereby, considerably reducing the probability of treating corrosion at a later stage.
  • The cost of corrosion treatment can far outweigh the dollars you spend on sandblasting before the coating process.
