Surface Preparation

Ensure all substrates are thoroughly clean, sound, dry and free from any contaminants such as dirt, salt, rust, mill scale, algae and grease.

New metal:

  • Abrade surface lightly and remove any surface rust or mill scale by sanding, wire brushing, with a chipping hammer, or sandblasting (sandblasting to SA2½ with a 40 to 50 profile gives the best results).
  • Clean away sanding dust, grease and dirt with Duram NS2 Galvanized Iron Cleaner according to instructions.
  • Rinse thoroughly with water until a water break-free surface is attained and allow to dry.

Aluminium and stainless steel:

  • Abrade surface with 220 grit waterpaper using Duram Xylene or turpentine as a lubricant. Rinse with Duram Xylene or lacquer thinners and allow to dry.


  • Stir Duram NS5 Metcote Etch Primer well.
  • Apply NS5 Metcote Etch Primer as soon as the substrate is dry.
  • Apply thinly by brush, roller or spray.
  • For conventional spray application, thin with lacquer thinners (approximately 20%) 16 - 20 secs (Ford Cup 4).
  • Allow NS5 Metcote Etch Primer to dry completely before overcoating.
  • Allow a minimum of 30 minutes to cure (at 25ºC).
  • When used for exterior applications, NS5 Metcote Etch Primer must be overcoated within 3 days to prevent oxidation.

IMPORTANT: For optimal protection against corrosion, apply Duram NS4 Anti-Rust Coating according to instructions before applying the topcoat (especially for humid and coastal environments).
