Immersion exposure

  • Steel or steel with not approved zinc silicate shop primer; blast cleaned (dry or wet) to ISO-Sa21⁄2, blasting profile 30 - 75 μm (1.2 – 3.0 mils)
  • Steel with approved zinc silicate shop primer; weld seams and areas of damaged shop primer or breakdown should be blast cleaned to ISO-Sa21⁄2, blasting profile 30 - 75 μm (1.2 – 3.0 mils) or power tool cleaned to SPSS-Pt3
  • Coated steel; hydrojetted to VIS WJ2L (blasting profile 30 – 75 μm (1.2 – 3.0 mils))
  • IMO-MSC.215(82) requirements for water ballast tanks
  • Steel; ISO 8501-3: 2006 grade P2, with all edges treated to a rounded radius of minimum 2 mm (0.0789 in) or subject to three pass grinding
  • Steel or steel with not approved zinc silicate shop primer; blast cleaned to ISO -Sa21⁄2, blasting profile 30 – 75 μm (1.2 – 3.0 mils)
  • Steel with approved zinc silicate shop primer; weld seams and areas of shop primer damage or break down should be blast cleaned to Iso-Sa 21⁄2 blasting profile 30 – 75 μm (1.2 – 3.0 mils): [1] For shop primer with IMO type approval; no additional requirements; [2] For shop primer without IMO type approval; blast cleaned to ISO-Sa2 removing at least 70% of intact shop primer, blasting profile 30 – 75 μm (1.2 – 3.0 mils)
  • Dust quantity rating "1 for dust size class "3", "4" or "5", lower dust size classes to be removed if visible on the surface to be coated without magnification (ISO 8502-3:1992)
  • Atmospheric exposure conditions
  • Steel blast cleaned to ISO-Sa21⁄2, blasting profile 30 - 75 μm (1.2 – 3.0 mils) or according to ISO-St3
  • Shop primed steel; pretreated to SPSS-Pt3
  • Galvanized steel must be sweep blasted or otherwise roughened
  • Galvanized steel must be free from grease, salts and any contamination
  • Concrete / Masonry
  • Remove grease, oil and other penetrating contaminants according to ASTM D4258
  • Abrade the surface per ASTM D4259 to remove all chalk and surface glaze or laitance. Achieve surface profile - ICRI CSP
  • 3 to 5
  • AMERCOAT 114 A may be used as a pit filler for certain applications. Check with PPG Technical Service for guidance on
  • chemical resistance
  • Maximum recommended moisture transmission rate is 3 lbs / 1,000 ft2 / 24 hours by moisture transmission test (ASTM
  • F1869, calcium chloride test or by ASTM D4263, plastic sheet test)
  • Alternatively, ASTM D4944 (Calcium Carbide Gas method) can be used, moisture content should not exceed 4%

Substrate temperature and application conditions

  • Substrate temperature during application and curing should be above 5°C (41°F)
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
  • Relative humidity during application and curing should not exceed 85%


Mixing ratio by volume: base to hardener 80:20 (4:1)
  • The temperature of the mixed base and hardener should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
  • Adding too much thinner results in reduced sag resistance and slower cure
  • Thinner should be added after mixing the components
