Abstract
In the method for coating substrate surfaces which are not water-absorbent, the substrate surfaces are coated with an aqueous composition which comprises an aqueous solution, dispersion and/or emulsion of film-forming substances and water-repellent substances, in which the coating can be removed by treatment with water. The method is also suitable for coating porous, water-absorbent substrates if the substrates are treated with a water-repellent prior to coating with the aqueous composition.
