Surface preparation

  • Remove all wax, oil and grease by solvent cleaning in accordance with the guidelines given by SSPC-SP1.
  • Wherever necessary remove weld spatter, round off all rough weld seams and smoothen sharp edges.
  • Abrasive blast clean to a minimum standard of Sa2½ (ISO 8501-1:1988) or SSPC-SP10 with an average surface profile of 40 to 75 microns.
  • Ensure that all surface defects detected after blast cleaning is ground, filled or treated in a suitable manner.
  • After blasting, remove dust from the surface. Ensure that the surface to be coated is clean, dry and free from any contaminants.
  • Apply Zincanode 685 immediately after blasting to prevent oxidation and recontamination. In case of oxidation / recontamination, re-blast to the required standard.
  • To avoid condensation of moisture onto substrate prior to coating application, relative humidity should not exceed 85% and substrate temperature should be more than 3°C above Dew Point.
