A method of improving the surface quality of a continuously cast slab, particularly a thin slab having a maximum cast thickness of 100 mm, wherein the slab is covered with a casting slag film and a layer of scale, and wherein the slab is descaled after casting and is rolled in a finishing train. A reaction agent, which is different from water, is applied onto the slab prior to descaling or during descaling. The application of the reaction agent may be preceded by a conventional hydraulic, mechanical or pneumatic removal of the layer of scale which covers the slab.
