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.


Abrasive blast clean to Sa21⁄2 (ISO 8501-1:2007). If oxidation has occurred between blasting and application of Interline 949, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process, should be ground, filled, or treated in the appropriate manner. A surface profile of 75-100 microns is recommended.



Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied.Once the unit has been mixed, it must be used within the working pot life specified. An optional retarder solution is available for this material. (See Limitations for details)

Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA853. Once units of paint have been mixed they should not be resealed and it is advised that after prolonged stoppages work recommences with freshly mixed units. Clean all equipment immediately after use with International GTA853. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning should be once every hour using GTA853 cooled to <15°C. All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation.


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.


Interline 949 can be applied in a wide range of climatic conditions, including elevated material temperatures up to 35° C. However, at material temperatures greater than 25°C the use of a retarder solution is required in order to maintain the working pot life, allowing normal airless spray methods to be employed. The recommended level of retarder is as follows:- <25°C - No retarder required 25-35°C - 1 unit retarder required These volumes of retarder will maintain the working pot life. The retarder must always be added to the base prior to the addition of the converter/curing agent and mixed thoroughly using a power agitator. This product must NOT be thinned as the use of thinners may severely inhibit the curing mechanism of the coating. This product will not cure adequately below 5°C. Maximum steel temperature at the time of application is 60°C and maximum relative humidity during the application and cure period is 80%. Under direct sunlight exposures or when surface temperatures exceed 35°C Interline 949 should be recoated as soon as the coating will support foot traffic in order to prevent the possibility of intercoat disbondment. 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.
