Vapor Honing
Vapor Honing (Wet Blasting) for Precision Surface Finishing
Vapor honing, also known as wet blasting, vapor blasting, slurry blasting, or liquid honing, is a precision surface preparation method used when the highest quality surface finish is required.
Unlike dry blasting methods, vapor honing uses water-borne abrasive media to clean and finish components in a controlled, dust-free environment, producing consistent and repeatable results.
What Is Vapor Honing?
Vapor honing differs from traditional dry blasting because the finish is achieved by the controlled flow of abrasive suspended in water rather than direct media impact. The water acts as a lubricant and cushioning agent between the media and the component surface.
This process reduces media ricochet, alters the impact angle, and creates a lapping action across the surface. The result is a uniform satin or lightly polished finish without aggressive material removal.
Because vapor honing is dust-free, it is safer for delicate components and preserves fine details while producing consistent surface finishes.
The Vapor Honing Process
Unlike dry blasting, vapor honing prevents abrasive media from becoming embedded in the component surface and eliminates airborne dust generated by media breakdown.
A specially designed glandless polyurethane pump continuously agitates water and abrasive into a slurry, which is then delivered to the blast gun. Compressed air is added at the nozzle to accelerate the slurry for effective cleaning.
After contacting the component, the slurry drains back into a sump, creating a closed-loop recirculating system. Broken-down media is removed through overflow filtration and sedimentation, ensuring consistent performance and media reuse.
Benefits of Vapor Honing
- Produces a uniform satin or lightly polished surface finish
- Less aggressive than dry blasting methods
- Preserves part geometry and fine details
- Dust-free and environmentally controlled process
- Prevents media embedding in component surfaces

Vapor Honing for Coating Applications
Vapor honing is commonly used as a preparation step prior to powder coating or ceramic coating, where surface appearance and dimensional integrity are critical.

Turnaround Time & Shipping
Turnaround time for vapor honing depends on part condition and workload. In many cases, vapor honing is completed as part of the overall coating preparation process.
We accept parts shipped from across the United States. All parts must be fully disassembled prior to shipment.
