High Pressure (HP) Water Blasting

High Pressure Water Blasting uses a pump which forces water from a nozzle at pressures up to 1400 bar (This figure can differ somewhat from standard to standard). A very good method with some limitations. 1400 bar will not achieve HB2 (the hydro-blasting equivelant of SA2)

Advantages

  • No Clean up of grit
  • Very good for sweeping large areas
  • Removes almost all salts and contaminants

Disadvantages

  • Requires a lot of water
  • Equipment is relatively expensive
  • Will not achieve an HB2 standard (SA2 equivalent) which is required for most "hard" coats.
  • Should be carried out by experienced people.
