Surface Preparation

Apply only on a clean and dry surface with a temperature above the dew point to avoid condensation. In confined spaces, provide adequate ventilation during application and drying.

Steel (Blast Cleaned):

  • Blast clean to ISO 8501-1 SA 2.5 with a blast profile of maximum 40 µm Rz

Steel / Cast Iron:

  • Machine sand with P80-120 discs and degrease

Galvanised Steel and Phosphated Steel:

  • Abrade with SCOTCHBRITE® and degrease

Aluminium / Light Alloys:

  • Machine sand with P240-320 discs and degrease

GRP:

  • Machine sand with P240 discs and degrease

Painted Surfaces and Fillers:

  • Machine sand with P320-400 discs and degrease



Mixing

  • Thoroughly mix paint before activating and check colour before use
  • The speed of drying can be increased with use of 1-490 Thinner, or 6-550 Accelerator (added at 1-2%) but these can reduce the final gloss and shorten the pot life
  • Use of 1-490 Thinner AND 6-550 together is not recommended
  • Use of 1-490 Thinner or 6-550 when applied directly to aluminium is not advised

Mixing Ratio:

  • Selemix 7-534/7-535 2K Polyurethane Direct Topcoat HS
    • 6 parts base  : 1 part hardener 

Please Note: Refer to the Product Data Sheet for detailed information regarding mixing ratios for the relevant binder/base and hardener/activator used.

Mixing ratios between the Standard, High Solids and Economy versions of this product vary due to the different hardeners used.
