What is Vapor Blasting?

A look at vapor blasting and how it compares with dry blasting and wet blasting.

What is Vapor Blasting?

Vapor abrasive blasting equipment combines water and abrasive in a pot that is under water pressure. The water and abrasive are then injected into the airflow for blasting. The air pressure and water/abrasive mix has fine tuning controls to dial in the blast parameters.

How does it affect the surface when blasted?

When wet abrasives impact a surface, fine particles are isolated into water droplets. The weight of the water combined with the abrasive directly prevents dust.

As the water droplets disperse, the hydrostatic force blasts away surface coatings, leaving behind a clean and feathered edge. This allows for a smooth application of the finishing coating.

What are the benefits?

There are a number of advantages to utilizing vapor blast equipment in your blasting applications, including:

  • One of most important advantages is the reduced dust, eliminating up to 92% of airborne dust particles.
  • The vapor blast process requires little or no containment during blasting due to the reduced dust. This allows for quicker set up and tear down for your mobile blasting solutions.
  • Safe to use on sensitive substrates (When using recommended media at appropriate blast pressures).
  • Vapor Blast equipment is adjustable for a wide range of blast pressures.
  • Effective in various weather conditions including (but not limited to) high humidity and rain.

What surfaces can I blast using vapor blast equipment?

Vapor blast equipment is safe to use on almost any surface or application, including (but not limited to):

  • Wood or Brick Cleaning
  • Coating & Painting Removal
  • Concrete Repair & Restoration
  • Concrete Cleaning & Surface Preparation
  • Steel Surface Preparation

How does it compare to dry blasting?

Vapor blasting consumes far less media than traditional dry blasting and can be used on almost any surface. It also eliminates up to 92% of airborne dust.

How does it compare to wet blasting?

Vapor blasting greatly reduces the amount of media and water used while blasting compared to traditional wet blasting. This is due to a more efficient mix created in the pressure pot.

There is no large slurry mess to clean up and it doesn’t create wastewater runoff.

What blasting abrasive can be used in vapor blast equipment?

You can utilize many types of blasting abrasives in a vapor blaster as long as they don’t react to or dissolve quickly in water. Some recommended blasting abrasives include Green Diamond, garnet, crushed glass, or Armex baking soda.

Important Note: When blasting ferrous substrates, a rust inhibitor needs to be used to protect the metal. This will provide better protection against flash rusting, even over the traditional dry blasting process.
