Vapour, Water & Aquablasting (Dustless Blasting): The Complete Guide

See our range of machines

Blasting technology has evolved to make surface preparation cleaner, safer, and more versatile. One of the fastest-growing methods in the UK is vapour blasting — also known as water blasting, Aquablasting, or dustless blasting. This guide explains how it works, when to use it, and why it’s becoming a go-to choice for many industries.

1. What Is Vapour / Aquablasting?

Vapour blasting mixes abrasive media with water and compressed air, creating a slurry that is fired at the surface.

  • The water cushions the abrasive, reducing its aggressiveness.

  • Dust is trapped in the water, massively cutting down airborne particles.

  • The process leaves a cleaner working environment compared to dry blasting.

2. Benefits of Vapour Blasting

  • Dust Control: Up to 92% less airborne dust compared to dry grit blasting.

  • Cleaner Finish: Water smooths the abrasive action, often leaving a satin-like finish.

  • Eco-Friendly: Lower dust emissions reduce environmental impact.

  • Reduced Media Use: Water helps media cut more efficiently, lowering consumption.

  • Versatility: Works on metals, composites, plastics, stone, and delicate restorations.

3. Applications

Vapour blasting is popular across a wide range of industries:

  • Automotive Restoration: Removing paint, carbon, grease, or rust without warping panels.

  • Marine & Offshore: Stripping coatings and corrosion while reducing airborne pollutants.

  • Aerospace: Cleaning engine components and composites without damage.

  • Engineering & Fabrication: Prepping surfaces for welding or coatings.

  • Conservation & Heritage: Gently cleaning stone, brickwork, or delicate masonry.

5. Limitations to Consider

  • Water Management: Creates wastewater that must be collected or contained.

  • Less Aggressive: Not as powerful as pure dry grit blasting for very thick coatings.

  • More Complex Setup: Requires water supply, hoses, and slurry management.

Final Thoughts

Vapour / Aquablasting offers the best balance of power and cleanliness, making it ideal where dust control and surface finish matter.

  • It’s widely used in automotive, marine, aerospace, and restoration industries.

  • If you need maximum cutting force, stick to dry grit blasting; if you need residue-free cleaning, dry ice may be better.

  • For most versatile jobs with environmental or dust-sensitive needs, vapour blasting is often the best choice.
