Abstract
Abstract An improved method for masking a portion of a surface in preparation for painting a surface. The method utilizes the step of adhering a strip of masking tape which is fully coated on one surface and the other surface of which is partly coated and partly uncoated with a pressure sensitive adhesive. The masking tape is first placed with the fully coated surface against the edge of the surface to be masked and with the uncoated outer surface position in the direction of the surface to be painted. A conventional paper and adhesive covering sheet is then affixed to the aforementioned masking tape to complete the masking operation.
