Structural Soda Blasting or Abrasive blasting is the projection at a surface of a suspended particulate in a pressurised air or water stream for the purpose of removing a coating or contaminant, or other alteration of that surface in some way. In our case, the surface is any building surface that forms part of ‘the structure’.

One of the most important differences between abrasive blasting with sodium bicarbonate (baking soda) versus abrasive blasting with any other abrasive medias are that baking soda’s attributes allow it to remove contaminants without damaging the underlying substrate.

Sodium bicarbonate is the ideal abrasive blasting media for the removal of oil and grease. When it comes to abrasive blasting many people use the common term “sandblasting,” but there are several mediums that can be used. Below, we outline the main difference between soda blasting, sandblasting and glass blasting.

Baking soda is considered a soft abrasive. It is typically harder than the surface contaminant, but softer than the substrate. One of the most important differences between blasting with sodium bicarbonate (baking soda) – versus blasting with any other abrasive media – is that baking soda’s attributes allow it to remove contaminants without damaging the underlying substrate.

“Sand” – technically aluminium oxide or silicon carbide – and glass are considered hard abrasives and additional care must be used when sandblasting or glass blasting to avoid any damage to the underlying substrate. Hard abrasive blasting is great when you’re not worried about removing substrate material. For example, if you’re refinishing a car and need to remove heavily rusted metal.

As specialists in the field of structural soda blasting, we primarily deal with concrete, steel and timber, but our highly trained operatives also specialise in the cleaning of brick and stone. Grit blasting comprises a mild abrasive and is best suited for the removal of surface contaminants, light rust, edge burrs and coating from most types of metal, including aluminium, cast iron and mild steel, as well as concrete and timber.
