Dustless Blasting works by mixing water and an abrasive inside the blast tank. By introducing water we’re drastically increasing mass and energy the machine is putting out, while at the same time eliminating dust.
Many people ask what the difference is between dry sand blasting and modern Dust Blasting. There are numerous advantage to Dustless Blasting:
The Dustless Blaster can strip a car in just a few hours.
- Minimal Dust
The abrasive gets trapped in water and grounded, eliminating the plume of dust.
- No Warping
The water prevents friction and won’t warp thin metal like sandblasting will.
- Less Containment Needed
In most cases, expensive, time consuming containment doesn’t need to be set up.
- Doesn’t Affect Nearby Workers
Never sacrifice productivity, other workers can work nearby unaffected.
- Leaves a Paint Ready Surface
The rust inhibitor decontaminates the metal leaving a clean, chloride free paint ready surface.
Since Water Is Used, Won’t It Rust Metal?
We use a rust inhibitor to prevent flash rusting for up to 72 hours. This extremely effective rust inhibitor is added to the blast water to prevent flash rust during blasting, and then used to rinse after blasting is complete.

Can The Dustless Blaster Cause Warping Like Sandblasting Can?
Warping occurs when the metal heats up due to friction from dry abrasive. The Dustless Blaster will not cause warping, because friction and heat are reduced by the water. In fact the temperature of the metal being blasted usually comes down about 10 degrees from ambient. Some people say warping can still occur regardless of temperature, we disagree. Have you ever seen a blacksmith working cold metal? With that being said, you can still bend metal by applying too much pressure, just like you could bend it with a solid object. For large flat pieces of metal like trunks or hoods we recommend using about 60 PSI at a 20º angle to avoid bending metal. Also, be careful not to separate the sheet metal from the betal bracing on the underside of a trunk or hood.
Will The Dustless Blaster Damage Chrome And Glass?
Glass and chrome can be damaged by any kind of abrasive blasting. You should always mask off the chrome and glass prior to blasting.
