Wet Blasting Technical Information

The Vapour Blasting Process

The wet blasting process is very similar to the process used for dry abrasive blasting, although the abrasive is propelled toward the surface of the metal using a slurry of water rather than high-pressure air. The process can vary slightly depending on the abrasive used. DECO uses automated machinery to wet blast large orders.

  • First, any holes on the part are masked or plugged
  • The abrasive particles are propelled towards the part in a stream pf high pressure water, using either a Water Injection Nozzle (WIN), Halo Nozzle, or inside a blasting chamber.
  • As the abrasive impacts the hard surface of the metal, the force of the impact blasts away the surface coating
  • The part is dried to prevent corrosion from the water. This MUST be done prior to adding another treatment or protective coating

Types of Wet Abrasive Blasting

  • Wet Bead Blasting: For a smooth peened finish, glass beads similar to those used in dry bead blasting are propelled against the metal.
  • Wet Soda Blasting: Soda is a softer, single abrasive generally used in instances where it is not necessary to recycle the slurry. It is often used special applications and for larger parts such as car and ship bodies.
  • Wet Aluminium Oxide Blasting: Generally used to clean, polish and create an anti-slip surface on metal

Quality Testing, Standards and Compliance

All DECO Industrial products are subjected to testing in our onsite Quality Testing lab. We ensure every DECO Industrial product and process meets Australian Standards, and does its job satisfactorily and to specifications.
