Surface information guides How to prepare and paint aluminium

The painting of an aluminium structure requires considerably more care in the preparation than most other surfaces, due to two factors.  

1. In the extruding process of aluminium, a rolling oil is used as a lubricant which remains on the surface long after the finished product is put into use. This has to be removed before painting can commence otherwise the paint will not adhere properly.
2. Because the metal is non-absorbent the adhesion of paint can only be mechanical (sitting on top of the metal). Therefore, any form of condensation or contamination will reduce adhesion and result in failure of the paint system.
