All surfaces to be coated should be clean, absolutely dry and oil or moisture free before painting application. Oil and grease should be removed by solvent cleaning.
New steel : Abrasive blasting to Sa 2½ (ISO 8501-1:2007). For temporary protection, if required, use a suitable shopprimer. All damage of shopprimer and contamination from storage and fabrication should be thoroughly cleaned prior to final painting.
Shop Primed : Indopoxy 740ZR is suitable for application to steelwork freshly coated with zinc silicate shop primers. If the zinc silicate shop primer shows extensive or widely scattered breakdown, or excessive zinc corrosion, overall sweep blasting is a must.
