Abstract: The invention relates to a protective coating for a mechanically stabile, in particular mineral and/or metallic base, comprising an inorganic polysilicate-cohesion adhesive layer which is uniformly distributed, essentially, on the base. A coating made of a glass film material having a thickness of less than 2 mm, preferably, less than 0.3 mm, is applied to the polysilicate cohesion adhesive layer prior to the hardening thereof, which covers the polysilicate-cohesion adhesive layer. According to the method for producing the protective coating, initially, the inorganic polysilicate-cohesion adhesive and the glass film material are prepared, then the cohesion adhesive is applied to the base which is to be coated and/or one side of the glass film material, and the glass film material is applied to the base which is to be coated prior to hardening of the polysilicate-cohesion adhesion layer, such that the glass film material covers the cohesion adhesion layer. Subsequently, the cohesion adhesion layer is hardened.
