Method for stripping a coating from a coated surface of a substrate, wherein the coating is stripped in an aqueous alkaline solution, characterized in that the method comprises following steps:&#x2014;preparing the coated substrate to be decoated by providing the substrate with a strippable coating by depositing a coating comprising one or more layers, wherein one layer comprising aluminum is deposited directly on the substrate surface to be decoated and&#x2014;introducting the substrate to be decoated in the aqueous alkaline solution, thereby conducting a chemical stripping of the coating from the substrate, whereas the aqueous alkaline solution comprises NaOH in a concentration in weight percentage from 30 wt. % to 50 wt. %.
