Preparation
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.
Repair/OBM
Prepare area to be repaired to a minimum of SSPC-SP2. Higher levels of surface preparation by abrasive blasting to SSPC-SP6 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 Interstores Alkyd Primer.
Overlap the primer onto existing coatings by approximately 2-3cm.
Consult International/Rawlins Technical for specific recommendations.
Application
Application |
---|
Mixing | This material is a one pack coating and should always be mixed thoroughly with a power agitator before application. |
Thinner | International GTA004. Thinning is not normally required. Consult the local representative for advice during application in extreme conditions. 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. |
Brush | Application by brush is recommended for small areas only. Multiple coats may be required to achieve specified film thickness. |
Roller | Application by roller is recommended for small areas only. Multiple coats may be required to achieve specified film thickness. |
Cleaner | International GTA004 |
Work Stoppages and Cleanup | Thoroughly flush all equipment with GTA004. All unused material should be stored in tightly closed containers. Partially filled containers may show a viscosity increase of the material after storage. Material should be filtered prior to use. |
Welding | 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. |
Safety
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.
Limitations
It is recommended that Interstores Alkyd Primer is not overcoated with epoxy coatings. In certain regions, for specific customer requests and where cosmetic properties are not of concern, Interstores Alkyd Primer may be applied without a cosmetic finish. Consult International or Rawlins Technical 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 International Paints or Rawlins Technical 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 the product 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.
