Grit blasting, or abrasive blasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.

Grit blasting is particularly useful for the removal of rust and old failing paint coatings to bring an old tired surface back to a bare, sound substrate. Grit blasting is also hugely effective in preparing corroded metal and poor masonry surfaces.

Abrasive blasting works by forcibly propelling a stream of material against a surface with a grit blasting rig and large compressor. The blasting rig is filled with abrasive blasting media and the compressor is used to create enough pressure to fire the grit at very high velocity, on to the surface.

This process will remove rust, contamination, salts, old failing coatings and damaged concrete to leave a clean, even surface ready for a coating system to be applied.

Grit blasting is done to effectively remove rust, corrosion, mill scale, contaminants and old failing paint coatings to bring old, tired and failing surfaces back to a bare, sound substrate.

Grit blasting is the most effective and fastest way to effectively prepare a surface prior to applying a coating system.

Grit blasting is classed as hot work because it can create sparks on the surface being blasted and also heats the surface as the friction from the abrasion of the grit hits the substrate.

Like grit blasting, steel grit blasting is the operation of forcibly propelling a stream of abrasive material against a metal surface under high pressure to smooth a rough surface, but more specifically is usually used on newly fabricated structural steel to slightly roughen the surface in order for an anti-corrosive primer to be applied to prevent the steel from rusting.

Steel grit blasting is also used on rusted or corroded steel to remove the rust and corrosion to create a new, bright steel surface with no rust or contaminants, prior to re-painting with an anti-corrosive coating system.

Steel grit blasting is the best possible preparation available for preparing corroded metal surfaces.

Shot blasting is a surface treatment process using high velocity steel abrasive balls to remove existing paint coatings or to roughen up a smooth surface prior to painting.

A large machine is usually moved across a surface at an even pace, firing small metal ball bearings at the surface at a very high velocity. These ball bearings break up the surface and can be used to open up very hard, dense concrete or remove existing old or failing floor coatings.

Shot blasting is a method through which it is possible to obtain excellent cleaning and surface preparation for secondary finishing operations.
