Fabric Maintenance

Abrasive grit blasting, also known as sandblasting, is a surface treatment process whereby abrasive particles are fired through a nozzle using compressed air. Grit blasting is widely used in a variety of industries to clean or modify the surface properties of components prior to coating application.

Grit blasting is the most effective means of surface preparation, it is used to remove rust and scale in the fettling of castings, and for dressing of stampings and billets, etc. It is often used to prepare surfaces before welding (removal of scale, rust, or paint), and afterwards to improve the adhesion of coatings (e.g. paint, or galvanising).

Surface preparation capabilities include:

  • Technical support and advice
  • Site surveys
  • Implementation
  • Provision of NACE & ICCOR accredited inspectors
  • In-house training and competence assessment

Typical methods include

  • Manual preparation
  • Power tool preparation – rotary tool and needle gunning
  • Hydro-blasting
  • Ultra-high-pressure water blasting
  • Abrasive blast cleaning (dry and wet)
  • Water washing – hot, cold and steam
  • Dry ice blasting
  • Chemical stripping
