Is vapor blasting the same as wet blasting?
Yes. Both terms describe abrasive media suspended in water and propelled by compressed air onto a surface. The water cushions every particle on impact, which is what separates the whole category from dry or grit blasting.
The split between the two names comes down to geography more than engineering. ‘Vapor blasting’ is the term you'll hear more often in North America. ‘Wet blasting’ is the established term across UK and European aerospace, medical device and industrial manufacturing, and it's the term Vapormatt uses across its own engineering documentation. Our wet blasting page covers that engineering in full: how the slurry is mixed, what governs the result, and how the process stays repeatable. This page covers the question people land here to ask, and the comparison most are actually trying to make: vapor blasting against dry blasting.
Vapor blasting vs dry blasting
Most people researching vapor blasting are weighing it against a dry or grit blasting process for a cleaning or finishing job. The two behave differently at the point of contact, and that difference shows up in the result.
| Vapor / wet blasting | Dry / grit blasting | |
|---|---|---|
| Impact | Cushioned by water, no embedding | Full velocity, media can embed in the substrate |
| Heat | Carried away by water, low distortion risk | Builds up, can warp thin or heat-sensitive parts |
| Dust | None. Trapped in the slurry | Airborne, needs extraction and ATEX-rated kit |
| Steps per pass | Cleans, finishes and degreases together | Cleans or finishes, rarely both |
| Typical finish | Fine, consistent, low roughness | Coarser and more variable |
Where vapor blasting is used
Vapormatt builds vapor blasting machines for manufacturers, and the industries below are where that work actually happens:
- Aircraft wheel and brake cleaning and stripping
- Aluminium extrusion die cleaning
- Composites, preparing surfaces for bonding without fibre damage
- Cutting tools, edge honing and deburring on carbide drills, mills and inserts
- Jet engine peening and preparation for NDT
- Medical and dental implants, controlling surface roughness for biocompatibility
- Wire and cable, de-glaring and improving feedstock cleanliness
You can learn more about the wet blasting applications for the industries above on our industries pages.
Where the process came from
In the late 1940s, Norman Ashworth was working alongside Sir Frank Whittle on early jet engine development. That work led him to a new process, originally called liquid honing, that combined water and abrasive media. Vapormatt grew directly out of that idea, and the Ashworth family still owns and runs the company four generations on. No competitors in vapor or wet blasting can say the same.
FAQs
Is vapor blasting better than dry blasting for sensitive components?
Often, yes. On parts where surface damage, heat distortion or media embedding is a risk, such as thin aircraft wheel sections, composite surfaces or fine cutting-tool edges, vapor blasting tends to be gentler and easier to control because the water cushions every impact.
Is vapor blasting safe to operate?
Yes. The process produces no airborne dust, so it avoids the respiratory hazards and ATEX requirements that come with dry blasting.
