System and compatibility

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

Surface preparations

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.


Prepare area to be repaired to a minimum of St2 (ISO 8501-1:1998). Higher levels of surface preparation by abrasive blasting to Sa2 (ISO 8501-1:2001) or hydroblasting to HB2M (International Paint Hydroblasting Standards), will enhance product performance. Feather or chip back surrounding area to a sound edge. Ensure that the area is clean and dry prior to application of Interprime 198. Overlap the primer onto existing coatings by approximately 2-3cm. Consult your International Paint representative for specific recommendations.



This material is a one pack coating and should always be mixed thoroughly with a power agitator before application.


Not recommended. Use International GTA007 only in exceptional circumstances. DO NOT thin more than allowed by local environmental legislation.

Airless Spray

Recommended Tip Range 0.53-0.66 mm (21-26 thou) Total output fluid pressure at spray tip not less than 176 kg/cm2 (2500 p.s.i.)

Conventional Spray

Application by conventional spray is not recommended.


Recommended. Multiple coats may be required to achieve specified dft.


Recommended. Multiple coats may be required to achieve specified dft.


International GTA007

Work Stoppages and Cleanup

Thoroughly flush all equipment with International GTA007. All unused material should be stored in tightly closed containers. Partially filled containers may show surface skinning and/or a viscosity increase of the material after storage. Material should be filtered prior to use.


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.


It is recommended that Interprime 198 is not overcoated with epoxy coatings. In certain regions, for specific customer requests and where cosmetic properties are not of concern, Interprime 198 may be applied without a cosmetic finish. Consult your regional technical centre for guidelines and details of colours available.

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.
