1. The selected coatings must meet the required technical specifications, and anyä¸åˆæ ¼ (non-conforming) coatings are strictly prohibited from being used in construction. 2. Before opening the paint can, ensure that the type, grade, color, and storage period match the intended use requirements, and confirm that the thinner is compatible. Once opened, the paint should be used immediately to avoid contamination or degradation. 3. After opening the paint, it should be thoroughly mixed to ensure even consistency. For epoxy-based paints, a curing agent must be added and mixed thoroughly before application. Pay close attention to mixing time to ensure proper chemical reaction before construction begins. 4. If dilution is necessary during painting, use the recommended thinner as specified by the manufacturer. The amount of thinner added should not exceed 5% of the total paint volume to maintain coating performance and integrity. Environmental Requirements for Coating 1. Avoid performing exterior painting during rainy, snowy, foggy, or high-humidity conditions, as these can negatively impact the drying process and adhesion of the paint. 2. Do not apply paint on wet surfaces, as this may lead to poor adhesion and long-term coating failure. 3. Painting should not be conducted if the humidity exceeds 85%, the outdoor temperature is above 30°C or below -5°C, or if the steel surface temperature is more than 3°C below the dew point. These conditions can cause condensation, leading to coating defects. 4. Avoid working in environments with excessive dust or severe pollution, as this can contaminate the painted surface and reduce the quality of the finish. Painting Construction Process Requirements 1. The painting method for the hull should follow these guidelines: a. The outer surface of the hull, deck, open decks, bulwark interiors and exteriors, and the upper parts of engine rudder plate steel are to be sprayed. b. Apply paint to welds, fillet welds, the back of profiles, and free edges before the main painting process begins. c. Other areas should be coated using brushes or rollers. 2. All painting work must be carried out strictly according to the “List of Painted Brands, Coatings, and Dry Film Thickness for Each Part of the Hull†to ensure consistency and compliance with design standards. 3. Before applying paint, the surface must be properly cleaned and inspected by designated personnel. Only after approval from the shipowner can the painting proceed. 4. Ensure that the painting tools used are compatible with the selected coating material. When switching between different types of coatings, all tools must be completely cleaned to prevent cross-contamination. 5. When applying paint, keep the surface clean and dry. Allow sufficient time for each coat to dry, following the minimum recoating interval specified by the manufacturer to avoid blistering or peeling. 6. To minimize the need for secondary cleaning, immediately clean and repaint all welds, cut edges (with chamfering), and areas affected by welding or cutting (excluding watertight test welds) with the appropriate shop primer after the welding or cutting is completed. 7. For areas requiring a high level of aesthetic finish, take care to avoid issues such as sagging or uneven accumulation of paint, ensuring a smooth and professional appearance.
