A masking process for masking a defined area on the surface of a substrate which is to be coated with a coating material which can be embrittled at low temperatures which comprises positioning cold sink masking means along the edges of the defined area, coating the masked substrate with the coating material, cooling the cold sink masking means and that portion of the coating which covers the cold sink masking means to the embrittlement point of the coating material, and then tearing the coating along the embrittled edges thereof so as to remove the coating from the masked area of the coated surface.
