  • Patent number: 4894102
    Abstract: Disclosed are a method and apparatus of refinishing a building panel such as a acoustic ceiling panel or tile. The method includes placing the building panel to be resurfaced on a support surface having a plurality of perforations. The building panel is placed so that its back surface is in contact with the perforated support surface. The perforations extend beyond the building panel's side edges. An adhesive is applied to one side of an air impervious sheet or film. The coated sheet or film is placed over the decorative surface of the building panel and over the exposed perforations in the support surface which are located beyond the building panel's side edges. Vacuum is drawn between the sheet or film and the perforated support surface via the perforations which is sufficient to enable ambient air pressure to force or collapse the sheet tightly against the decorative surface so that the sheet substantially assumes or conforms to the contour of the building panel's decorative surface.
