Film application method and construction panel

Abstract

A method of applying a protective film to a construction panel comprising: a) selectively applying an adhesive composition to a peripheral region of a surface of the construction panel; and/or selectively applying an adhesive composition to a peripheral region of a surface of the protective film; and b) applying a protective film to the surface of the construction panel to bond the protective film to the construction panel. A construction panel comprising a protective film layer on a surface of the panel and a peripheral adhesive composition layer located between said surface of the panel and the protective film layer, wherein the peripheral adhesive composition layer extends from an edge of the panel and across from about 0.1% to about 25% of the width of the surface.
