Application Conditions

• Only apply in conditions of good ventilation which must be maintained during drying and curing. 
• Do not apply when rain, mist, sleet or snow are imminent.
• During application and drying time of the paint coating, the surface should be dry, the Relative Humidity should not exceed 85% and the steel temperature should remain at least 3ºC above the dew point.
• Only apply this product when the above conditions can be maintained throughout the critical application and drying/curing process.
  
  

Application Methods

• Airless Spray: Output fluid pressure at tip 2000-3000 psi, Tip Size: 19-27 thou (0.48-0.68mm).
• Brush application will typically achieve up to 125 microns dft, airless spray up to 200 microns dft.
• Avoid exceeding the maximum stated dry film thickness.
• Refer to Axalta Coating Systems ‘Epoxy Application and Curing Notes’.

Product Notes

• Overcoating with conventional, chlorinated rubber or vinyl: ideally overcoat between 24-48 hours at 23ºC. Maximum is 7 days or abrading is required.
• Overcoating with epoxy or two pack polyurethane:min 24 hours, max 3 months, at 23ºC.
• Overcoating with alkyds: starting with ViterLac AM112 MIO is recommended for good intercoat adhesion. Min 24 hours, max 7 days, or abrading will be required.
• Extend min/max drying and overcoating times at lower temperatures and for DFTs above 125 microns
• Do not apply below 2ºC.
