In case of hydrojetting the flash rust degree shall not exceed moderate in SSPC and NACE standards for water prepare surfaces.
Shop primed steel: Clean, dry and undamaged approved shopprimer. Coated surfaces Clean, dry and undamaged compatible primer. Contact us for more information.
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.
