  • New Surfaces

Remove all dust and dirt. Wash surface with mineral turps and then thoroughly with water to remove all traces of forming oil, grease, and other contaminants.

  • Previously Painted Surfaces

Remove all unsound cracking or flaking paint with scraping and sanding. Remove all rust, chalk, dust, oil, grease and other contaminants including any “white rust” deposits.
Ensure any rusted areas on galvanised iron, steel brackets etc are thoroughly abraded to remove rust and are primed with Anti Corrosive Metal Primer before applying Gal Iron Primer.


ONE coat of GAL IRON PRIMER is recommended. Apply by airless spray. Use a brush on small and difficult areas.


Thoroughly stir paint in a circular lifting motion using a flat paddle. Thin up to 5% with water (only if necessary) to assist application in hot windy conditions. Do not apply at surface temperatures below 10 degrees Celsius and cease application if surface dry time exceeds 40 minutes.

Do not apply if rain or moisture condensation is imminent. (Do not apply to exterior surfaces after 3 pm if overnight dew condensation is likely)
