Metal roof painting Central Coast

Inspect before recoating

• Existing finish and adhesion
• Surface rust and corrosion extent
• Screws, washers and fixings
• Sheet damage and incompatible metals
• Flashings, valleys and penetrations
• Drainage and safe access

Rust treatment is not one-size-fits-all

Loose rust and unsound coating may require mechanical preparation, followed by cleaning and a compatible corrosion-control or primer system. Heavily corroded sheets or fixings may require replacement rather than coating.

Previously painted metal roofs

Dulux notes that previously painted surfaces require thorough cleaning and adhesion assessment before recoating. Existing coating variability can affect the available system and warranty conditions.

Colorbond and other factory finishes

A factory-applied finish is different from an aftermarket repaint. COLORBOND notes that overpainting will not be as durable as the original factory finish, so condition and expectations should be discussed carefully.
