Before painting the surface shall not be glossy with moisture, but can have a patchy appearance. The surrounding air must have a relative humidity not exceeding 85 Hydrojetting of steel surface makes a wet surface. Good ventilation is required in confined areas to ensure proper drying. The temperature of the substrate should be minimum +10☌ (Std) (-5☌ in WG) and at least 3☌ above the dew point of the air, temperature and relative humidity measured in the vicinity of the substrate. Please contact your local Jotun office for more information. The coating may be used on other substrates. For maintenance UHPWJ to WJ2 (NACE No.5/SSPC-SP 12) or Power tool cleaning to min. Contact your local Jotun office for more information. Coated surfacesĬlean, dry and undamaged compatible primer. Shopprimed steelĬlean, dry and undamaged approved shopprimer. In case of waterjetting the flash rust degree shall not exceed M (moderate) in SSPC and NACE standards for waterjetted surfaces. Improved surface treatment (blast cleaning to Sa 2½) will improve the performance. Bare steelĬleanliness: Power tool cleaning to min. The surface should be assessed and treated in accordance with ISO 8504. *Measured according to ISO 3233:1998 (E) Surface preparationĪll surfaces should be clean, dry and free from contamination.
