Ensure the surface has thoroughly dried prior to application. Do not apply on top of existing painted surfaces. Aged/lightly rusted surfaces: Remove any rust by scraping, sanding or wire brushing. Wipe surface with Dulux Metalshield® Brush Thinner to remove any residual grease, oils and dirt.  New bare steel, wrought iron: Wipe surface with Dulux Metalshield® Brush Thinner to remove any residual grease, oils and dirt. Galvanised iron: Clean surface with Selleys® Sugar Soap and a Scotch-Brite® Pad to remove any grease, oils and dirt. Rinse with clean water.

Before spraying: Shake can well for at least two minutes after the ball starts rattling and regularly during use. Lower temperatures and high humidity will slow the drying and affect the gloss level. Avoid spraying when air or surface temperature is below 10°C or above 30°C.

During spraying: Hold the can upright 10 to 25cm from the surface. To ensure surface compatibility, test spray on inconspicuous area. Spray with smooth even strokes, parallel to the surface. Apply several light mist coats rather than one heavy coat, which can cause runs and sags.

After spraying: Prevent blocking by turning the can upside down and spraying until clear gas emerges. Also wipe front of nozzle clean. Clean up overspray while it is still wet with mineral turpentine.
