1. A plastic corner joint simulating grout line adapted to join together at least two wall board panels simulating tiles embedded in grout at a corner intersection comprising:

  • a first base section having an outer edge and an inner edge;

    a second base section having an outer edge and an inner edge, said inner edge of said second base section being adjacent and joined to said inner edge of said first base section, said second base section extending from said inner edge of said first base section and being substantially perpendicular to said first base section, said second base section being substantially straight between its outer and inner edges;

    a substantially straight rib extending from said first base section toward said outer edge of said second base section, said rib being disposed adjacent said second base section and being canted toward said second base section, said rib, first base section and second base section defining a first channel adapted to receive at least a first wall board panel;

    a flange, including an outer surface which is concave in cross-section and simulates a grout line, extending from said rib in the direction of said outer edge of said first base section and being inclined toward said first base section, said flange, rib and first base section defining a second channel adapted to receive at least a second wall board panel in a substantially perpendicular relationship to said at least first wall board panel.
