THE VAPOUR BLAST SYSTEM

What is Vapour Blasting? 

Vapor abrasive blasting (also known as wet abrasive blasting) removes coatings, contaminants, corrosion and residues from hard surfaces. It’s similar to dry blasting, except that the blast media is moistened prior to impacting the surface.

The main advantage of vapor abrasive blasting over dry blasting is that it reduces dust, allowing for operators to work in a wide range of environments with minimal setup and cleanup costs. It results in a cleaner, more consistent finished, ready to coat, with no embedded particles or clinging dust.

Vapor abrasive blasting is alternatively referred to as wet blasting, wet abrasive blasting, vapor blasting, slurry blasting, wet sandblasting and dustless blasting.

How does Vapour Blasting work? 

Water and abrasive are combined in a pot under water pressure and then precisely metered into the airflow. When wet abrasive impacts a surface, the additional water weighs the particles down and creates a “dustless” effect.

Since our Vapour Blast Machine uses less water than slurry or other water-based technologies, pools of water aren’t left behind so there is less need to worry about toxic runoff.

What happens on impact?

When abrasive impacts a hard surface, the particle often breaks or shatters, propelling finer particles into the air as dust, in addition to dust already present in the dry media. This impact can also cause dry sparks charged with static electricity.

When wet abrasive impacts a surface, fine particles are sequestered in water droplets. The additional water weighs the particles down, preventing dust.

The presence of water also confers more mass on the particle at impact. As the water droplet disperses, the hydrostatic force blasts away surface coating, leaving a feathered edge around the perimeter for seamless recoatings.
