Product Details

Drying Times

Surface 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 freshwater wash or freshwater wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.

Newbuilding/Major Refurbishment

• Ensure the wood is clean and dry prior to application
• For new wood it is recommended that the first coat is thinned 50% with GTA004 for maximum penetration into the wood

Repair/OBM

• Ensure the wood is clean and dry prior to application
• Interlac 678 may be applied directly over aged Interlac 678 following thorough freshwater washing and degreasing provided the coating to be overcoated is in an intact and tightly adherent condition
• Loose or flaking coatings should be removed back to a firm edge and Interlac 678 or an appropriate primer should be used to repair the area before application of the full coat

Priming Bare Wood

• The addition of GTA004 may be required for the application of the first coat to new wood, 50% maximum by volume.

Application Conditions

• 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

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 Rawlins for advice during application in extreme conditions
• Do not thin more than allowed by local environmental legislation

Airless Spray

• Suitable
• Tip Range 0.33-0.38 mm (13-15 thou)
• Total output fluid pressure at spray tip not less than 176 kg/cm² (2500 p.s.i.)

Conventional Spray

• Use suitable proprietary equipment
• Thinning may be required

Brush

• Recommended

Roller

• Recommended

Limitations

• Overcoating information is given for guidance only and is subject to regional variation depending upon local climate and environmental conditions
• 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

Health and Safety

• 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 (i.e. gloves, goggles, face masks, barrier creams etc.)
• Actual safety measures are dependent on application methods and work environment
