The surface must be clean and dry, free from grease, rust and dirt. Protect adjoining surfaces from overspray.

Before spraying: Shake can for at least three minutes before use 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.

Spray application: Hold can upright 15 to 25cm from the surface. To ensure surface compatibility, test spray on an inconspicuous area. Spray with smooth, even strokes parallel to the surface. Apply with several light mist coats rather than one heavy coat, which can cause running and sagging.
Note: Dulux Duramax Undercoat can be wet sanded after two hours.

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.
