What type of paint should I use to paint aluminium cladding?
Answer In general, use a top of the line exterior 100% acrylic house and trim paint in a flat or semigloss finish. This assumes proper surface preparation, including removal of dirt, chalk and mildew. Unless metal is exposed, no primer is needed. If bare metal is visible, remove any white oxide with a non-metallic scouring pad such as ScotchBrite, then wash off and rinse, then apply a acrylic exterior corrosion inhibitive primer to the exposed metal area. As for the paint, use a flat if the cladding is at all uneven and/or dented (while the semigloss finish will provide a rich, fresh appearance, it will accentuate the dents.
