Overcoat Preparation

  • Stir the paint thoroughly before using
  • Use recommended thinners only
  • Do not over thin the paint more than the recommended levels

Surface Preparation

  • Ensure removal of dirt, grease, loosely bound or flaking materials from the surface.
  • Remove all traces of oil or grease using solvent wipes.
  • Blast clean the surfaces complying with minimum Sa2.5 (ISO 8501-1:2007) or SSPC-SP6.
  • Ensure that the recommended surface profile is in the range of 35-50 microns.
  • Prepare metal surfaces to the level of Sa2.5.
  • Use power tool cleaning complying with SSPC-SP11 in conditions, where blasting is not possible.

Application Method

  • Apply a coat of Sheenlac 3100 within the over coating intervals specified in the datasheet of the primer.
  • Allow it to dry as per the time interval mentioned above.

Application Precautions

  • Do not apply this product over damp substrates or steel below the dew point.
  • Do not apply when the humidity is above 85% RH.
  • If the over coating interval or sunlight exposure is longer, ensure proper preparation of the surface, before over coating. This ensures proper inter-coat adhesion.
  • Refer MSDS of the product, available on request.
  • Keep out of reach of children.
  • Use personal protective equipment like goggles, face masks and gloves.
