Aluminium is a lightweight, durable substrate widely used in automotive, industrial, and domestic applications due to its resistance to corrosion and ease of fabrication. Unlike steel, aluminium does not rust, but it can form a natural oxide layer on its surface, which can make paint adhesion more challenging if not properly prepared.

To achieve a strong and lasting finish, aluminium surfaces should be thoroughly cleaned to remove grease, dirt, and oxidation, then lightly abraded to create a key. The use of a suitable primer, such as an etch primer, is essential to promote adhesion and ensure the coating bonds effectively to the surface.

Once prepared, aluminium can be coated with a variety of finishes, from standard paints to specialist coatings depending on the application. With the correct preparation and products, aluminium substrates can achieve a smooth, durable, and professional-quality finish suitable for both interior and exterior use.
