    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 7-532/7-533 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.
