A method for indicating the periphery line of a patch of an optionally resilient surface layer of a substrate object which patch is intended to be removed in a step, which may cause a change of the appearance of the surface, which method comprises the application on the surface of an adhesive mask, comprising an outer, "negative: and/or optionally an inner, slat "positive" mask component, comprising one or more layers of a sheet material, which can be brought to adhere to the surface of the object, wherein the negative mask comprises a main opening with a borderline, which forms an inner borderline of the mask, and the positive mask comprises a slab with a borderline, which forms an outer borderline of the mask, said inner and/or outer borderlines having essentially the shape of the intended periphery line of the patch of the surface layer intended to be removed, said main opening of slab having circular or preferably elongated, non-circular shape, preferably with a ratio of lengthwise extension on transverse extension of at least 2 or at least 3 and optionally at most 10. |
