Unpainted Cladding

The practice of leaving metal-coated roof cladding to weather before painting is no longer required. With the latest developments in primers, roofs can now be painted immediately after installation.

• For un-weathered AZ-coated cladding, only acrylic galvanised iron primers should be used, as solvent-borne primers may damage the coating. A solvent-borne corrosion-resistant galvanised-iron primer should, however, be used for optimum performance on weathered AZ or galvanised-coated cladding. Wash and allow to dry (see preparation above.
• Apply primer.
• Apply two coats of acrylic roofing paint in the selected colour to provide the required paint thickness. (Typically two brush-applied coats achieve 50 µm).
