Yes. But before you do, clean the surface. This can be done using a mop or soft bristle brush with non-ionic detergent (such as kitchen detergent) and water. The surface should then be hosed down thoroughly with water and allowed to dry.

If the surface is new, it may contain some residual lubricants from the roll forming process. These should also be removed using the procedure outlined above. If possible, new surfaces can be sanded lightly to enhance paint adhesion. This is not required on older, weathered COLORBOND® steel.

Once the surface is clean, you can directly overpaint it using two coats (preferably) of a good quality water-based exterior acrylic. Please follow the manufacturer's instructions. If the steel is being used to catch drinking water, also check with the manufacturer that the paint is suitable for this purpose.

It's important to note that overpainting COLORBOND® steel will void any warranties issued by BlueScope Steel. Should, for any reason, overpainting be undertaken on behalf of and under instruction from BlueScope Steel, then a future warranty (if any) position will be negotiated between the customer and BlueScope Steel.
