Abstract
This disclosure relates to using polyester films on building boards to enable improved surface coatings. The polyester film is preferably applied to a glass mat via an adhesive to form a laminate. This laminate is then bonded to the exterior surface of a gypsum board. The polyester film is advantageous because it allows for exterior surface coatings to be applied. In one embodiment, an exterior acrylic coating is applied to the polyester film. Boards constructed in accordance with this disclosure allow for exterior finishings to be achieved without the need for excessive finishing materials or steps.
