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. This product is suitable for use over phosphate washed steel.
Primed Surface : Already primed (or wash primed) surface should be dry and free from all contamination and Indoprotect 490ZC should be applied within the overcoating intervals specified in earlier primer/ etch primer TDS. Area of damaged primer or rework etc should be prepared as per specified standards, either by power tool cleaning or other means.
Wood : Clean and dry surface. Surface contamination is to be removed by detergents and fresh water cleaning.
Steel : Abrasive blast clean to a minimum of Sa2½ (ISO 8501-1:2007). Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner. A surface profile of 30-40 microns is recommended.
Aluminium : The surface should be hand or machine abraded with non-metallic abrasives or bonded fibre machine or hand abrasive pads to impart a scratch pattern to the surface and to remove all polish from the surface. Else abrasive sweep blast to a standard similar to ISO 8501-1:2007 Sa1 to create a surface profile would be best method for surface prepration.
