Abstract: An exterior material for home appliances comprises a plastic material; and a coating layer formed on the top of the plastic material. The coating layer may comprise at least one of a wax-based additive, a fluorine-based additive, or a wax-based additive and a fluorine-based additive by applying a coating solution having a viscosity of about 10 to 100 g/cm s that comprises the at least one additive.
