Acrylic paint can be used on most surfaces, including metal. Acrylic paint is highly versatile and can achieve a wide variety of effects. Due to its low price and quick dry time, it is a very popular type of paint. Metal, like most surfaces, needs to be prepared before painted.
Acrylic paint does not adhere well to particularly smooth surfaces. In order to overcome this problem, metals should be sandpapered or sandblasted before applying paint. The right texture is a rough, matte surface. After the right texture is achieved, an industrial primer should be applied to the metal surface. After drying, painting can commence.
