Marine microstripping

Cheshire Heritage Blasting specialises in a comprehensive array of maritime coating removal services, designed to cater to a variety of vessels including wooden boats, steel canal boats, commercial vessels, and fiberglass craft. Our expertise lies particularly in antifoul removal and replacement, effectively stripping away old paint, rust, and other coatings to prepare for the application of new protective layers. Utilising advanced microblasting technology, our process is finely tuned to meet the delicate needs of each individual vessel, ensuring that the integrity and performance of the boat or ship are enhanced.

What is Microblasting and why should it be used?

Microblasting, also known as precision blasting or micro-abrasive blasting, is a process that uses a fine abrasive media propelled through a small nozzle at low velocity to clean or etch a surface on a very small and detailed scale. This technique allows for precise, controlled removal of surface materials without affecting the integrity of the item being cleaned or processed.

Areas on the vessel that can be microblasted

Microblasting, also known as precision or fine media blasting, can be used on various parts of a vessel for cleaning, paint removal, or surface preparation. Here’s where it can be applied:

1. Hull: To clean the surface, remove old paint or antifoul, and prepare for painting or repairs.
2. Deck Surfaces: For non-slip texture improvement or to clean and restore teak decks.
3. Superstructure: On parts like the bridge, wheelhouse, and deckhouses for paint removal and surface preparation.
4. Masts and Spars: Careful cleaning and paint removal on aluminium or wooden components.
5. Propellers and Running Gear: To remove marine growth or old coatings without damaging the underlying metal.
6. Engine Components: For precision cleaning of engine parts, including turbos, to remove carbon deposits and other contaminants.
7. Rudders and Keels: To strip coatings, preparing the surface for new coatings.

Note: The specific suitability of microblasting for each part of the vessel depends on the material and its condition.

What is the difference between Microblasting and Traditional sandblasting?

The difference lies primarily in the scale and precision of the surface treatment process, as well as the specific applications for which each method is best suited.

In summary, microblasting is distinguished from traditional sandblasting by its lower pressure, finer abrasive media, and precision-focused applications. While traditional sandblasting excels at aggressive material removal on a larger scale, microblasting offers a more controlled and delicate approach, making it particularly well-suited for detailed and selective surface treatments.

Why Microblasting for Maritime Coatings Removal:

1. Precision: Microblasting allows for exact targeting of unwanted coatings without damaging the substrate, essential for the varied materials found in maritime crafts.
2. Environmentally Friendly: This method minimises dust and debris, reducing environmental impact, particularly crucial in marine settings.
3. Versatility: Suitable for multiple surface types, including wood, steel, and fiberglass, microblasting is adaptable to the needs of any maritime vessel.
4. Surface Preparation: Not only does microblasting remove existing coatings, but it also prepares surfaces for optimal adherence of new coatings.

The Process from Start to Finish:

1. Initial Assessment
   • A detailed inspection of the vessel to understand the condition of existing coatings and the type of substrate.
   • Determination of the precise microblasting approach suitable for the material and extent of coating removal required.
2. Protection of Nearby Areas
   • Shielding and securing adjacent areas to prevent any possible contamination or damage during the coating removal process.
3. Media Selection
   • Choosing the correct blasting media based on the type of vessel material and the nature of the coating to be removed.
4. Microblasting Application
   • Setting up the microblasting equipment with the right pressure and abrasive flow for gentle yet effective removal.
   • Systematically progressing over the vessel’s surfaces to strip away antifoul, paint, and rust without harm.
5. Thorough Cleaning Post-Blasting
   • Removal of all debris and dust resulting from the microblasting to leave a clean surface.
6. Surface Evaluation
   • Inspecting the exposed surface for uniformity and readiness to receive new coatings.
   • Addressing any minor repairs or surface treatments needed prior to coating.
7. Application of New Coatings
   • Applying an appropriate primer, antifoul, or other specified coatings to protect the vessel against future marine growth and corrosion.
8. Final Inspection
   • Conducting a comprehensive review to ensure all areas meet high standards of preparation and finish.
   • Confirming that the vessel is fully restored and primed for enhancing maritime performance.

Antifoul application ( if desired )

Applying industry-leading antifoul paint to your vessel is a critical process for maintaining its performance and longevity. Antifoul paint, also known as bottom paint, is specially formulated to prevent the growth of marine organisms such as barnacles, algae, and slime on the hull—a phenomenon known as biofouling. Application of antifoul paint is typically a multi-step process:

1. Preparation: The hull must be thoroughly cleaned, and any existing antifouling paint should be removed if it’s incompatible with the new product or if it’s in poor condition. The surface is then sanded and cleaned to ensure it’s smooth and free of contaminants.
2. Priming: If needed, a primer is applied to protect the hull and ensure good adhesion for the antifoul paint. The type of primer will depend on the material of the hull and the type of antifoul paint being used.
3. Application of Antifoul Paint: Antifoul paint can be applied by brush, roller, or spray, and usually requires at least two coats. The number of coats, drying times, and methods of application should follow the paint manufacturer’s recommendations.
4. Curing: After applying the necessary coats of antifoul, the vessel must be left to dry for a period specified by the paint manufacturer. This allows the paint to cure and ensures its effectiveness once the boat is back in the water.
5. Maintenance: Regular inspections and maintenance of the antifoul coating are important to retain its effectiveness. The frequency of reapplication will depend on the type of antifoul, the waters the vessel is used in, and how often the boat is used.

It’s important to choose an antifoul paint that’s appropriate for your vessel type, the water it is used in, and is compliant with environmental regulations.

The key features of microblasting include:

1. Precision: The ability to target very small areas with pinpoint accuracy makes microblasting an ideal choice for delicate or intricate applications.
2. Control: Users can adjust various parameters such as pressure, abrasive media type, and nozzle size to control the intensity and area of impact.
3. Versatility: Microblasting can be used on a variety of materials.
4. Minimal Damage: The process is gentle enough to remove only the intended surface layer without causing damage to the underlying material.

In conclusion, Cheshire Heritage Blasting’s microblasting service offers an efficient and delicate restoration method.
