For the paint system best suited to the surface to be protected, consult your local International Paint representative.
For other information, refer to the International Paint application procedure.
Typical systems: Intershield 456/Intershield 6GV. Intershield 456/Intershield 6GV/Interthane 990. Intershield 456/Intershield 6GV/Interthane 990HS. Or Intershield 456/Intershield 6LV. Intershield 456/Intershield 6LV/Interthane 990. Intershield 456/Intershield 6LV/Interthane 990HS. Or Intershield 456/Intershield 5150LWT. Intershield 456/Intershield 5150LWT/Interthane 990. Intershield 456/Intershield 5150LWT/Interthane 990HS
Paint only on clean, dry surfaces. Remove all grease, oil, soluble contaminants and other foreign matter by solvent cleaning per SSPC-SP1.
Steel: for ideal performance, "near-white blast cleaning" (SSPC-SP10) is recommended.
High-pressure water derusting to International Paint HB2½L (SSPC WJ2) standard, with slight flash rusting acceptable.
A surface roughness of at least 75 µm is required.
If oxidation occurs between blasting and application of Intershield 456, re-blast to the specified standard.
Where abrasive blasting is not possible, use "power-tool cleaning" (SSPC-SP11).
Aluminium: for aluminium and light alloy surfaces, solvent-clean per SSPC-SP1, then physically phosphating-treat by abrasive blasting.
For specific advice, consult your local International Paint representative.
Note: for marine environments outside North America, the following surface preparation standards may be used: Sa 2.5 (ISO 8501-1:2007) instead of SSPC-SP10; Pt3 (JSRA SPSS:1984) instead of SSPC-SP11; St3 (ISO 8501-1:2007) instead of SSPC-SP11.
Apply by brush, roller or spray.
Apply the mixed coating as a smooth, even film on suitably prepared surfaces by brush, roller or spray.
Applying a 150 µm wet film produces a 125 µm dry film. Recoat intervals must be observed. If the maximum recoat interval is exceeded, the surface must be abraded before applying the subsequent coat.
See the introductions for the following equipment:
Do not weigh out and mix the coating until ready for use. The coating is supplied in two containers as a kit. Always mix the entire kit in the supplied proportions when using. (1) Stir component A with a power stirrer. (2) Mix all of component A and component B and stir thoroughly with a power stirrer. (3) Below 23 °C, the coating should have a 15-minute "induction" period. Do not mix freshly mixed coating with coating nearing the end of its pot life.
Do not thin
Pump with minimum ratio 56:1; nozzle tip 0.017–0.023 in (432–584 µm); high-pressure paint hose with 3/8 in (9.5 mm) internal diameter; 60-mesh nozzle filter.
N/A
Use a Chinese hog-bristle brush of a suitable size.
Brush application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Use a multipurpose roller sleeve with 3/8 in (9.5 mm) smooth-to-medium nap. Pre-clean the roller sleeve before use to remove loose fibres.
Roller application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
International GTA220/GTA415
Clean all equipment immediately after use with International GTA220/GTA415. Periodic flushing of spray equipment during the working day is good practice. The number of flushings depends on the quantity sprayed, temperature and time used (including delays). Do not exceed the pot life of the coating.
All surplus paint and empty containers must be disposed of in accordance with appropriate 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.

Apply in good weather, with air and surface temperatures above 10 °C. The surface temperature shall be at least 3 °C above the dew point. For optimum performance, bring the paint temperature to 21–27 °C before mixing and application.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
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.
