For the paint system best suited to the surface to be protected, consult your local International Paint representative.
Applied in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated must be clean, dry and free of contaminants.
Wash with high-pressure or ordinary fresh water as appropriate, and remove all oil, grease, soluble contaminants and other foreign matter in accordance with the SSPC-SP1 solvent cleaning standard.
Before applying International Paint systems, the ideal method for treating most non-ferrous and galvanized surfaces is: after the above treatment, use brush-off blasting or abrading. For blast cleaning, use low air pressure and fine abrasive suitable for the substrate (0.2–0.5 mm), with the nozzle 1 m (3 ft) from the surface. Interprime 539 should only be used when this operation is impossible.
Non-ferrous metals: ensure the surface is clean, dry and free of metal corrosion products.
When the substrate is aluminium or light alloy, the surface should be solvent-cleaned and then chemically etched with Interprime 539. It is important to then apply a paint system suitable for aluminium over Interprime 539 (consult International Paint).
Galvanized steel: remove grease to SSPC-SP1 standard, and use hand or power tool cleaning to remove any white zinc corrosion products.
This coating is a single-component product; stir thoroughly with a power mixer before application.
Not recommended. Use International GTA220 only in special cases. Do not thin beyond the range permitted by local environmental regulations.
Recommended nozzle size 0.25–0.38 mm (10–15 thou); total output fluid pressure at the nozzle not less than 112 kg/cm² (1590 lb/in²).
Recommended.
International GTA220
Flush all equipment thoroughly with International GTA220. All unused paint shall be stored in tightly closed containers. Containers not completely filled may develop surface skinning and/or increased paint viscosity after storage. Paint should be filtered before use.
All equipment should be cleaned with International GTA220 immediately after use. Flushing the spray equipment periodically during the day is good working practice. The number of cleanings depends on factors such as spray volume, temperature and use time (including work interruptions). Pay close attention to the paint condition. All leftover paint and empty containers shall be disposed of in accordance with local regulations/laws.
If welding or flame cutting is performed on metal coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation. In North America, follow the instructions in ANSI/ASC Z49.1 “Safety in Welding and Cutting”.
All work related to the application and use of this product must comply with national health, safety and environmental protection standards and regulations.
Before using this product, obtain, read and follow the health and safety information in the Material Safety Data Sheet for the product. Read and observe all precautions in the Material Safety Data Sheet and on the container label. If these warnings and requirements are not fully understood, or cannot be strictly observed, do not use the product. During application and drying of the product, provide adequate ventilation and protective measures to keep solvent vapour concentrations within safe limits, so as to prevent poisoning or oxygen deficiency. Take protective measures to avoid skin and eye contact with the product (e.g. gloves, goggles, face shield, barrier cream). Specific safety measures depend on the application method and working environment.

Care must be taken to ensure the surface to be treated is completely free of grease, otherwise the subsequent coat will not achieve good adhesion.
When applying Interprime 539 by airless spray, in some cases up to 10% of the recommended thinner can be added to help paint penetration.
Excessive film thickness can cause peeling when overcoated with high-build systems.
When applying Interprime 539 in enclosed areas, ensure adequate ventilation.
Excessive application of subsequent coats containing strong mixed solvents can cause softening of Interprime 539. This will cause subsequent loss of adhesion when the subsequent coat dries/cures and should be avoided.
Interprime 539 is not suitable for underwater or waterline areas.
This product will not cure adequately below 5 °C. For ideal performance, the curing temperature should be above 10 °C.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
Apply in good weather. The temperature of the surface to be coated must be at least 3 °C above the dew point. Unless otherwise specifically instructed, raise the paint temperature to between 21 and 27 °C before mixing and application to achieve optimum application performance. Unmixed paint (in sealed containers) must be stored protectively as specified in the Storage section of this product data sheet. The technical and application data given here are intended as general guidance for establishing an application procedure. Test results are obtained in a controlled laboratory environment, and International Paint does not claim that the published test results, or any other test results, accurately represent results obtained in all site environments. Because application, environmental and design parameters vary widely, care must be exercised in coating selection, performance verification and use.
