VOC values are typical and are provided for guidance purposes only. These may be subject to variation depending on factors such as differences in colour and normal manufacturing tolerances.


Consult your International Paint representative for the system best suited for the surfaces to be protected.


Use in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated should be clean, dry and free from contamination.
High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.



Where necessary, remove weld spatter and smooth weld seams and sharp edges.
Abrasive blast clean to Sa21⁄2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Intergard 821, the surface should be reblasted to the specified visual standard.


Prepare bare areas of steel by blasting to Sa21⁄2 ISO 8501:1. Feather or chip back surrounding area to a sound edge. Roughen the exposed edge of the existing Intergard 821 to provide a mechanical key. Overlap the Intergard 821 onto this abraded area.


Blast out to Sa21⁄2 ISO 8501-1:2001. If cleaning cannot be carried out effectively by blasting, mechanically grind out the pits using a suitable carborundum head.
Apply appropriate primer before oxidation occurs.
Apply the Intergard 821 within the overcoating interval specified for the primer, (consult relevant primer data sheet). Ensure that the area is clean and dry prior to application of Intergard 821.

Consult your International Paint representative for specific recommendations.

Work Stoppages and Cleanup

Monitor material conditions, do not exceed pot life limitations. Clean all equipment immediately after use with International GTA822.


In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation. In North America do so in accordance with instruction in ANSI/ASC Z49.1 "Safety in Welding and Cutting."


All work involving the application and use of this product should be performed in compliance with all relevant national Health, Safety & Environmental standards and regulations.

Prior to use, obtain, consult and follow the Material Safety Data Sheet for this product concerning health and safety information. Read and follow all precautionary notices on the Material Safety Data Sheet and container labels. If you do not fully understand these warnings and instructions or if you can not strictly comply with them, do not use this product. Proper ventilation and protective measures must be provided during application and drying to keep solvent vapour concentrations within safe limits and to protect against toxic or oxygen deficient hazards. Take precautions to avoid skin and eye contact (ie. gloves, goggles, face masks, barrier creams etc.) Actual safety measures are dependant on application methods and work environment.



This product will not cure adequately below 5°C. For maximum performance the curing temperature should be above 10°C. In humid conditions, the surface of Intergard 821 may develop a "sweat" which must be washed off with fresh water before overcoating.

Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions. Consult your local International Paint representative for specific recommendations. Apply in good weather. Temperature of the surface to be coated must be at least 3°C above the dew point. For optimum application properties bring the material to 21-27°C, unless specifically instructed otherwise, prior to mixing and application. Unmixed material (in closed containers) should be maintained in protected storage in accordance with information given in the STORAGE Section of this data sheet. Technical and application data herein is for the purpose of establishing a general guideline of the coating application procedures. Test performance results were obtained in a controlled laboratory environment and International Paint makes no claim that the exhibited published test results, or any other tests, accurately represent results found in all field environments. As application, environmental and design factors can vary significantly, due care should be exercised in the selection, verification of performance and use of the coating.
