1. A method of forming a sound damping wallboard, the method comprising the steps of:
providing a first gypsum layer having a first side wherein the first side includes a first gypsum surface portion and is partly covered with a first encasing layer to provide a first encasing layer portion;
providing a second gypsum layer having a second side wherein the second side includes a second gypsum surface portion and is partly covered with a second encasing layer to provide a second encasing layer portion;
applying a sound damping layer on the first side to cover at least part of the first encasing layer portion and the first gypsum surface portion and/or applying a sound damping layer on the second side to cover at least part of the second encasing layer portion and the second gypsum surface portion; and
positioning the first side of the first gypsum layer to the second side of the second gypsum layer.
