1. All selected coatings must comply with the technical specifications provided. Any coating that does not meet these standards should not be used during the construction process. 2. Before opening the paint can, ensure that the type, grade, color, and storage period match the intended use. Also, confirm that the thinner being used is compatible. Once the can is opened, it should be used immediately to avoid contamination or degradation. 3. After opening the paint, stir it thoroughly to ensure an even mixture. For epoxy paints, add the curing agent as specified and mix well. Pay close attention to mixing time before starting the application process. 4. If dilution is required during painting, use the recommended thinner from the manufacturer. The amount of thinner added should not exceed 5% of the total paint volume to maintain the integrity of the coating. Environmental Requirements for Coating Application 1. Avoid performing outdoor painting in rainy, snowy, foggy, or high-humidity conditions. These weather conditions can affect the adhesion and quality of the coating. 2. Do not apply paint on wet or damp surfaces, as this can lead to poor bonding and premature failure of the coating. 3. Painting should not be carried out 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 compromise the performance of the coating. 4. Avoid working in environments with excessive dust or pollution, as this can cause contamination and reduce the quality of the finished coating. Painting Construction Process Requirements 1. The hull painting should be carried out according to the following guidelines: a. The outer surface of the hull, deck, open decks, bulwark interiors and exteriors, and the upper part of the engine rudder plate should be sprayed. b. Apply paint to welds, fillet welds, the back of profiles, and free edges before the main painting begins. c. Other areas should be painted using brushes or rollers. 2. Follow the "List of Painted Brands, Coatings, and Dry Film Thickness for Each Part of the Hull" strictly during the application process. 3. Ensure that the painted surface is clean and meets all required standards. Only proceed after inspection by a designated personnel and approval from the shipowner. 4. Use painting tools that are compatible with the selected coating. When switching to a different type of coating, make sure to thoroughly clean all tools to prevent cross-contamination. 5. Keep the surface clean and dry before applying paint. Allow sufficient drying time, which should not be less than the minimum interval recommended by the manufacturer. 6. To minimize the need for secondary cleaning, clean and repaint any welds, cuts, or free edges (with chamfering) immediately after welding or cutting. Use the appropriate shop primer for these areas. 7. For areas where appearance is important, take care to avoid issues like sagging or uneven accumulation of the coating, ensuring a smooth and professional finish.
