Surface Preparation: All surfaces should be clean and free from contamination. The surface should be assessed and treated in accordance with ISO 8504.
Bare steel: Power tool cleaning to min. St 2, mill scale free (ISO 8501-1:2007). Improved surface treatment (blast cleaning to Sa 21⁄2) will improve the performance. In case of hydrojetting the flash rust degree shall not exceed moderate in SSPC and NACE standards for water prepared surfaces.
Shopprimed steel: Clean, dry and undamaged approved shopprimer.
Coated surfaces: Clean, dry and undamaged compatible primer.
For maintenance: UHPWJ to WJ2 (NACE No.5/SSPC-SP 12) or Power tool cleaning to min. St 2 for rusted areas.
Other surfaces: The coating may be used on other substrates.

Typical Use: Protective: Designed as heat resistant coating. Suitable for insulated and non insulated surfaces. Recommended in combination with an inorganic zinc silicate coating as primer, providing heat resistance up to 400°C and long corrosion protection. For shorter periods, such a combined system can handle peak temperatures up to 540°C.
It is recommended to use brush for the first coat.
Spray: Use air spray or airless spray.
Brush: Recommended for stripe coating and small areas. Care must be taken to achieve the specified dry film thickness.
Roller: May be used for small areas. Not recommended for first primer coat. Care must be taken to achieve the specified dry film thickness.
