Aluminium foil is made from aluminium alloy. It comes in pieces of various sizes and is less than .2mm thick. Aluminium foil is most commonly found in small rolls and sold in grocery stores. These rolls are used to package foods. Aluminium foil is sold in only the aluminium tint but it can be painted to change the colour for art projects or other household designs. Painting aluminium foil is similar to painting any other type of metal.
Lay a dust sheet or other type of tarp on a flat surface and set the aluminium foil on top. Wipe down the aluminium foil with a clean rag. Remove any grease or other debris from the surface. Dampen the rag with water and scrub out the tougher spots, if necessary.
Hold a can of etching primer at least six inches from the surface of the aluminium foil. Remove the cap from the primer and line up the can at any corner of the aluminium foil.
Spray the primer intermittently and move the can back and forth over the foil. Do not stay in one spot too long. Continue over the entire piece of aluminium foil until it is completely covered in the primer. Wait at least three hours for the primer to properly dry before applying the paint.
Spray acrylic latex spray-paint over the aluminium foil. Move back and forth, spraying intermittently until the paint has completely covered the primer. Wait two hours for the paint to dry. Apply a second coat, if necessary.
