Application steps

SURFACE PREPARATION

Steel:

Remove all weld spatter, then grind welds and joints in accordance with EN 14879-1.

Blast cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

Average roughness depth RZ ≥ 50 μm.


Stainless steel and aluminium:

Sweep blast in accordance with ISO 12944-4.

Only non-metallic abrasives should be used.

Average roughness depth RZ ≥ 50 μm.

Ensure substrate is free from contaminants detrimental to adhesion.

MIXING

Application exclusively with 2-pack-hotspray airless equipment. Stir both components separately prior to application.
Do not add any thinner.

APPLICATION

Hot spraying:

  • Undiluted
  • Use special airless hot-spray machine
  • Nozzle size ≥ 0.53 mm (0.021 inch)
  • Spraying angle: e.g. 50°
  • Temperature at nozzle: + 65°C to + 70°C
 


Repair:

  • Undiluted
  • Suitable only for the repair of small areas!


Clean and prepare damaged areas by sanding or sweep blasting of areas to be coated and ensure thorough removal of dust. As soon as possible the cold mixed material should be applied by trowel.
