metal surfaces

pre-painting

  • The surface should be absolutely free from dirt, dust, grease, rust, moisture etc.
  • Cover the area that you don’t want to paint with a masking tape, paper and/or cloth.

surface preparation

  • De-grease and de-rust ferrous metal substrates by suitable treatment.
  • For nonferrous metal substrates like aluminium, galvanised iron, tin etc. pre-treat the surface with etch primer.
  • For ferrous metal substrates, apply AP Metal Primer - Corrosion Resistant, either by brushing or spraying.
  • The use of AP Knifing Paste Filler is recommended to fill up dents and rectify surface imperfections.
  • Ensure that the surface is free from moisture and loose matter.
  • Apply one more coat of AP Metal Primer- Corrosion Resistant by brushing or spraying to cover puttied areas.
  • For best results, allow the primer coat to dry for 6 hours and dry sand with emery paper no. 320 before application of subsequent coat.

painting

  • Allow the surface to dry overnight after application of primer as mentioned above.
  • Apply top coat (Apcolite Premium Gloss Enamel or Apcolite Premium Satin Enamel, Gattu Synthetic Enamel) using the recommended thinner. For best results, apply two coats allowing 8 hours of drying time between two coats.
  • The first coat should be wet sanded with waterproof emery paper grade 400 before applying the second coat.
