Sweep-blasting will be performed to remove loose paint, dirt, and light rust. A chemical etching solution will be used to prepare metal surfaces for painting. The Contractor will submit a list of all chemicals to the COR for approval prior to use.

3.2 Commercial Blasting

For areas with severe rust, the Contractor will perform commercial blasting to remove all coatings down to bare metal, ensuring no compromised sections remain.

3.3 Inspection and Touch-Ups

After blasting, all surfaces will be inspected by the COR, and the Contractor will address any imperfections as necessary.

3.4 Preparation Quality Assurance

All surfaces must be free from dust, debris, and blasting media. The Contractor will use gauges to measure surface profiles, ensuring they meet the required standards for optimal paint application, in accordance with SSPC (Society for Protective Coatings) or NACE (National Association of Corrosion Engineers) guidelines.

4.0 Painting and Coating

4.1 Application of Epoxy and Urethane Coatings

The Contractor will apply two coats of 9100 Epoxy on the top side of the ferry, followed by two coats of Wasser moisture-cured urethane on the sides and bottom. Handrails, pipes, and tanks will receive two coats of 9100 Epoxy. All applications must strictly adhere to the manufacturer’s guidelines for mixing, application, and curing.

4.2 Marking Safety Lines

The Contractor will use a durable, anti-slip paint for the deck and ramps to ensure safety in all weather conditions. The paint must be specifically designed for marine environments and provide a slip-resistant surface, such as Dura Grip or an approve equal. The paint must be suitable for application on the ferry and must be approved by the COR prior to use.

Salient Characteristics of Dura Grip

• Anti-Slip Surface: Provides a textured finish that significantly reduces slip hazards, meeting ASTM standards for slip resistance.

• Durability: Designed for high durability in marine environments, effectively resisting wear from foot traffic, water exposure, and UV radiation.

• Adhesion: Exhibits strong adhesion to various substrates, including, metal (e.g., aluminum, steel), wood, and fiberglass. Passes adhesion tests as per ASTM D3359.

• Water Resistance: Engineered to be water-resistant, preventing blisters and peeling in wet conditions.

• Quick Drying Time: Dries to the touch within 1-2 hours and achieves full cure within 24 hours.

• Application Methods: Compatible with various application methods, including airless spray, roller, or brush. Ensures even coverage without drips or runs.

• Low VOC Content: Formulated with low volatile organic compounds (VOCs), compliant with EPA regulations.

• Color and Finish Options: Available in various colors, including safety yellow (Color Code:

13538) and gray, to meet safety and aesthetic standards.

• Maintenance: Requires minimal maintenance; surfaces can be cleaned easily using water and mild detergents.

• Compliance: Meets performance standards set by OSHA for workplace safety and EPA for environmental regulations.
