Fast and safe cleaning and finish of defence components and materiel

Our wet blasting technology is used to clean and finish a wide range of land-based, naval, and aerospace defence components and materiel worldwide.

Wet blasting is a critical process for maintaining the operational readiness, longevity, and reliability of defence components across all branches of the military.

It is particularly effective at maintenance, overhaul, and repair operations thanks to its speed, combining cleaning and surface finishing processes into a single operation. Wet blasting cleans and finishes components safely by containing harmful dust and paint particles in the process’ water.

The applications and benefits of finishing aerospace components by wet blasting are covered in detail on our Aerospace MRO and Aerospace OEM pages.

Key advantages of wet blasting for defence include…
  • Speed: Multiple cleaning and finishing processes can be carried out in a single rapid operation to help ensure military assets are quickly back in service.
  • Safety: Thanks to the water element of wet blasting, dust and airborne particles are contained, making it safer for personnel and sensitive environments. The wet blasting process does not use harmful chemicals.
  • Material and geometry integrity: Gentle on delicate or precise components, such as gun barrels or hydraulic systems. The geometry of components remains unaltered and underlying substrates are not damaged.
  • Process control: Our wet blasting machines are highly versatile, finishing delicate surfaces without damage or aggressively finishing surfaces when required. Our automatic machines can reliably and repeatedly produce the same uniform finish.
  • Environmentally friendly: Our wet blasting machines recycle water and blast media. The process does not use harmful chemicals, and waste can often be disposed of without special requirements.
General applications of wet blasting for defence include…
  • Decontamination: Harmful chemicals, asbestos, and radioactive particles are contained in the water of the wet blasting process, avoiding the creation of dust that might contain these contaminants.
  • Cleaning: Highly effective at removing grease, oils, burrs, rust, carbon, chemical deposits, scale, and other contaminants without damaging underlying paint or substrates.
  • Paint stripping: By adjusting blast pressure and media type, paint can be rapidly stripped from components without damaging the substrate. If required, an individual layer of paint can be removed while leaving underlying layers intact.
  • Inspection: Rapid cleaning and paint stripping in a single operation produces a perfect surface for inspection and subsequent repair.
  • Coatings: Creates ideal uniform surfaces on metals, composites, and other materials for anodising, plating, painting, and other coatings like CVC and CVD.
  • Bonding: Ensures even application of adhesives for maximum bond strength.
  • Creation of non-reflective surfaces: Wet blasting is highly effective at creating non-reflective surfaces, which can often be advantageous for military applications.
  • Smaller components: Fixings, gears, and other smaller components can be cleaned and finished in volume using our barrel-configured machines.

Land-based defence systems

Ground vehicles

Wet blasting is essential for cleaning and finishing ground defence vehicles, as it removes rust, coatings, and contaminants. This process prevents corrosion, enhances durability, and prepares surfaces for optimal adhesion of protective coatings or paint. Wet blasting ensures these vehicles remain reliable, operational, and ready for extreme conditions and demanding environments.

Tank

Tanks and armoured vehicles: Thorough cleaning (removing grease, oil, rust, and carbon buildup) and paint stripping in preparation for crack detection and subsequent re-coating. The water in wet blasting contains any toxic harmful paint dust, or even asbestos, that might exist, unlike dry blasting. The process does not tie up the time of skilled staff with laborious manual cleaning.

Engine and drivetrain components: Degreasing and cleaning components like cylinder heads, pistons, crankshafts, valves, gearboxes, and axles. Wet blasting using a glass bead media cleans and demagnetises components, helping to ensure metal contaminants are fully removed.

Cleaning brake components: Wet blasting cleans brake drums, discs, callipers, and other components by removing contaminants such as dirt, grease, oil, and rust without damaging the underlying surface. It can also strip paint and prepare surfaces for reassembly, painting, coating, or other treatments by creating a clean, consistent finish.

Suspension and undercarriage: Cleaning parts such as coil springs, dampers, and tracks to ensure operational reliability.

Weapon mounts and turrets: Cleaning and preparation for resurfacing weapon mounts to maintain proper alignment and functionality.

Vehicle Brake Components
Artillery systems

Wet blasting cleans and finishes artillery systems by removing contaminants, rust, and coatings, ensuring reliability, preventing corrosion, enhancing surface adhesion for protective layers, and maintaining optimal performance in demanding operational conditions.

Artillery System

Gun barrels and breech components: Removing carbon fouling, rust, and wear residues from howitzers and other large artillery. Cleaning bores rapidly to quickly get artillery pieces back into service without damaging barrel rifling.

Shell casings and breech blocks: Cleaning and finishing components to ensure smooth operation.

Teflon coating removal and re-application:Rapid coating and surface preparation for re-application in a single operation.

Military transport and utility vehicles

Wet blasting cleans military transport and utility vehicles by removing dirt, rust, and old coatings, preventing corrosion, enhancing surface finish, and ensuring durability, optimal performance, and effective protection in harsh environments.

Structural frames: Cleaning truck frames and support structures to prepare for repair or re-painting.

Cooling systems: Cleaning radiators and heat exchangers to improve thermal efficiency.
