For details, consult the local International Paint representative.
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.
On newbuildings, remove weld spatter and grind welds and sharp edges smooth where required.
Weld seams and damaged areas of shop primer shall be abrasive blasted to Sa2½ (ISO 8501-1:2007) or power tool cleaned to Pt3 (JSRA SPSS:1984) or St3 (ISO 8501-21/SIS 05 59 00).
Intact, approved shop primer must be clean, dry and free of soluble salts and any other surface contaminants.
Unapproved shop primer must be fully blast cleaned to Sa 2.5 (ISO 8501-1:2007). In some cases, sweep blasting to a specified International Paint standard (e.g. AS2 or AS3) is acceptable. For specific advice, consult your local International Paint representative.
Precautions For marine environments in North America, the following surface preparation standards may be used: SSPC-SP10 instead of Sa2.5 (ISO 8501-1:2007) SSPC-SP11 instead of St3 (ISO 8501-1:2007) SSPC-SP11 instead of Pt3 (JSRA SPSS:1984)
The coating is supplied in two containers as one unit. Always mix the entire unit in the supplied ratio. Once mixed, use within the specified pot life.
(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the base (Component A) with the curing agent (Component B) and stir thoroughly with a power mixer.
International - GTA220. Thinning is generally not required. Under extreme conditions, consult the local representative for application advice. Do not thin beyond the limits permitted by local environmental regulations.
Recommended nozzle tip size 0.53-0.66 mm (21-26 thou); total fluid output pressure at the nozzle not less than 246 kg/cm² (3500 psi)
Conventional spray application is not recommended.
Brush application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Roller application is recommended for small areas only. Several coats may be required to achieve the specified film thickness.
Do not allow paint to remain in hoses, spray guns or spray equipment. Flush all equipment thoroughly with thinner. International GTA220/GTA822. Once a paint unit has been mixed, it shall not be resealed; if application is interrupted for a long period, remix the components before resuming application.
All equipment shall be cleaned with International GTA220/GTA822 immediately after use. Periodic flushing of spray equipment during the working day is good working practice. Flush once per hour using GTA220/GTA822 cooled to below 15°C.
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.

Before recoating, Intergard 6788 coatings shall be washed where necessary with high-pressure fresh water and/or solvent to ensure removal of all accumulated surface contamination.
Drying times and overcoating intervals may vary with site factors such as humidity, tank geometry and ventilation rate.
Intergard 6788 may be applied to substrates at temperatures as low as -5°C, but low-temperature recoating shall be considered, since other coats in the system may require higher temperatures to achieve full cure.
Recoat data are for guidance only and shall depend on local climatic and environmental conditions. For specific advice, consult the 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. To achieve optimum application performance, raise the paint temperature to between 21-27°C before mixing and application. Ensure relative humidity below 80%, otherwise drying and recoat times will be severely extended. Unmixed paint (in tightly closed containers) shall be stored protectively in accordance with the 'Storage' section of this product data sheet. The technical and application data mentioned here are intended to provide general guidelines for a paint application programme. Test performance results derive from controlled laboratory environments; International Paint does not claim that the published test results, or any other tests, precisely represent results obtained in all field environments. Because application, environmental and design parameters vary widely, great care shall be exercised in coating selection, performance verification and use.
