Process for finishing a plastic surface

Abstract

A method is disclosed for restoring weathered plastic surfaces and for enhancing the resistance of the treated surface to sunlight. The surface of a plastic article being treated is first cleaned with a suitable cleaning agent and the surface is polished with a mild abrasive to remove major imperfections in the surface. Following cleaning and polishing, a first layer of an uncured adhesive material is applied over the surface. The adhesive material is selected from those compositions that are ultraviolet curable. An outer coat of a curable adhesive is applied over the uncured to form a semi-permanent outer surface on the article. The article then can be exposed to sunlight and other effects of weathering and over a period of time the underyling ultraviolet curable coating is gradually cured by exposure to sunlight so that the composite coating on the surface of the article becomes even tougher and better cured the more the article is exposed to sunlight.
