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 specification provided. All surfaces to be coated should be clean, dry and free of contamination prior to the application of each coat. High pressure fresh water wash or fresh water wash and scrub as appropriate to remove all dust etc from the surface. Grease and Oil etc should be removed by degreasing or solvent wiping to AS1627.1 - 2003 providing a "water breakfree" surface free of contaminates.


Interzone 954 should be applied directly to AS1627.4 class 2.5 surface where practical. If a holding primer is required Intergard 269 may be used. Keep within the specified overcoating intervals (consult the relevant product data sheet).


The surface should be degreased to AS1627.1 - 2003 and washed with copious amounts of fresh water to form a "water breakfree" surface. Spot abrasive blast to AS1627.4 class 2.5 or power tool cleaned to AS1627.2 class 3. International Paints Hydroblasting Standard HB2M is also acceptable. All edges should be feathered 2-3cm back to a sound edge. Recommended Blast Profile of 50-75 microns. If a holding primer is required Intergard 269 may be used. The surface should be dry and free from all contamination prior to the application of the Interzone 954 and should be applied within the specified overcoating intervals. Interzone 954 can be applied over aged or re-oxidised (gingered) areas as long as it is not loosely adhered.


Interzone 954 may be applied directly to a UHP Hydroblasted to International Paint Visual Hydroblast Standard HB2M or Slurry Blasted to SA2 Surface Standard.

Do NOT apply over existing Intergard Epoxy Polyester (EN43) Systems.


Confined Spaces - Forced air ventilation may be required. See relevant Material Safety Data Sheets.


Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied. (1) Agitate Base (Part A) with a power agitator. (2) Combine entire contents of Curing Agent (Part B) with Base (Part A) and mix thoroughly with power agitator.


Thinning is not recommended. If thinning is required in exceptional circumstances use International GTA220 (max 5% by volume). 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 190 - 246 kg/cm2 (2700 - 3500 p.s.i.)

Conventional Spray

Use suitable proprietry equipment. Thinning may be required to achieve atomisation. Multiple coats may be required to achieve minimum specified dry film thickness.


Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.


Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film thickness.


International GTA822 or International GTA220 (USA)

Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA822. 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 GTA822. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays. Do not exceed pot life limitations. 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.


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 ambient temperatures should be above 10°C. Thinning not suitable in Ballast water tanks. If thinned for conventional spray do not used in a tank coating situation. In common with all epoxy based coatings Interzone 954 will exhibit chalking of the film on UV exposure. Forced air ventilation and air movement are required for an even cure of this product. 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.
