Abstract:
A method for masking the surface of a substrate while applying two or more coatings to the surface, comprising the following steps:a) applying a protective tape to a first portion of the surface which is to remain non-roughened; b) roughening a second portion of the surface adjacent the first portion; c) removing the protective tape from the first portion of the surface; d) covering a primary section of the first portion of the surface with a protective sheet, while leaving a fracture zone uncovered, said fracture zone being situated adjacent the second portion of the surface; e) covering the fracture zone and at least a portion of the protective sheet adjacent the fracture zone with a durable tape; f) applying a first coating over the substrate surface, so that it adheres to the roughened, second portion of the surface; g) removing the durable tape to uncover the fracture zone and the portion of the protective sheet; h) applying a second coating over the surface of the substrate, covering and adhering to the first coating, but not substantially adhering to the fracture zone; and i) removing the protective sheet.
