When painting surfaces made of aluminum or galvanized steel, corrosion protection is generally less critical, as these materials are significantly more resistant to atmospheric corrosion compared to steel. In such cases, the primary concerns are adhesion to the substrate and maintaining the decorative appearance of the coating. Therefore, the correct choice of primer becomes the key factor. The RILAK product range includes VL-02 primer, which offers excellent adhesion to both aluminum and galvanized steel. It is important to note that for aluminum and galvanized surfaces, the VL-02 base component should be mixed with an acid hardener in a weight ratio of 8:1, whereas for steel surfaces, the ratio is 4:1. Below are the recommended coating systems for aluminum and galvanized steel surfaces:
