The shipbuilding and marine industry faces one of the harshest working environments in the world. Constant exposure to saltwater, humidity, and changing weather conditions causes rapid corrosion and surface deterioration of ships, vessels, and marine equipment.
To combat this, sand blasting plays a vital role in maintaining and restoring marine assets. At Aerowheel Surface Finishing, we specialize in providing high-quality sand blasting solutions tailored for the demanding needs of the shipbuilding and marine sectors.
Importance of Sand Blasting in the Marine Industry
In shipbuilding and maintenance, surface preparation is the first and most critical step before painting or coating. Even the strongest marine paints will fail if applied to a corroded or contaminated surface.
Sand blasting helps by:
- Removing rust, scale, and old coatings completely.
- Creating a clean and rough surface profile for better coating adhesion.
- Extending the lifespan of marine coatings against saltwater corrosion.
- Reducing long-term maintenance and repair costs.
Applications of Sand Blasting in Shipbuilding
1. Hull Cleaning and Preparation
The hull of a ship faces the most corrosion and fouling. Sand blasting removes:
- Rust, algae, barnacles, and marine deposits.
- Old paint layers before new coating applications.
This ensures the new protective coating bonds strongly and resists seawater damage.
2. Deck and Superstructure Maintenance
Decks and upper structures are exposed to harsh sunlight and sea spray.
Sand blasting helps:
- Eliminate oxidation and peeling paint.
- Prepare the surface for anti-slip coatings or fresh paint layers.
3. Tank and Engine Room Cleaning
Fuel tanks, ballast tanks, and engine compartments accumulate grease, corrosion, and residues.
A controlled sand blasting process safely removes these contaminants, ensuring:
- Clean interiors
- Better performance
- Reduced risk of contamination or leakage
4. Propeller and Rudder Refurbishing
These underwater components often suffer from pitting and fouling.
Sand blasting restores their smooth finish without altering dimensions, improving overall ship efficiency.
Types of Sand Blasting Used in Marine Applications
Dry Sand Blasting
Best for heavy corrosion removal on steel hulls and large surfaces. Requires proper dust control systems.
Wet Sand Blasting (Vapour Blasting)
Ideal for reducing dust in confined or sensitive marine environments. The addition of water prevents airborne contamination and static buildup.

Abrasive Media Used
Common abrasives for marine blasting include:
- Steel grit
- Copper slag
- Garnet sand
- Aluminum oxide
The choice depends on surface hardness and required finish.
Safety and Environmental Considerations
Sand blasting in shipyards must follow strict safety and environmental standards:
- Use of proper PPE (helmets, respirators, suits).
- Dust collection systems to prevent pollution.
- Disposal of used abrasives as per marine waste regulations.
At Aerowheel Surface Finishing, we use eco-friendly abrasives and dust-controlled systems to minimize environmental impact while delivering high-efficiency results.
