Simultaneous removal & profiling
Overview
The Bristle Blaster® Subsea is our hydraulic underwater device with a unique water drive. It creates a profiled surface, ideal for the mechanical bonding of protective materials against corrosion. Connected to a power unit via a single, neutrally buoyant high-pressure hose, the Subsea achieves a surface preparation grade comparable to ISO 8501-1 Sa2 ½ or Sa3.
- Powerful and serviceable water motor
- Torque and speed adjustable with the high-pressure unit
- Removes corrosion, coatings, scale and adhesive residue

Simultaneous removal & profiling, in one pass
Impact
Bristle tips strike the surface at kinetic energy comparable to abrasive grit-blast media.
Accelerator bar
The patented accelerator bar amplifies tip impact for maximum removal efficiency.
Retraction
Tips retract instantly, creating the anchor profile without smearing, burnishing or heat.
Coating-ready
A clean, profiled, grit-free substrate, comparable to ISO 8501-1 Sa 2½ & Sa3, 65–85 µm Rz (2.6–3.3 mil), ready to coat.
Same result. None of the downsides.
The power of blasting. None of the fallout.
Grit-free
No loose abrasive, no media, minimal containment.
Comparable to ISO 8501-1 Sa 2½ & Sa3
A verified, coating-ready standard. SSPC-SP 10 / SP 5.
In-service & spot repair
