Channel Screed

A wall system comprising a channel screed disposed within a wall surface, wherein the channel screed comprises:

• an elongate channel member having an internal channel defined by a base and opposed walls, wherein the base is attached to an underlying wall structure, and wherein a building materiaL used to form the wall surface, is in contact with outside surfaces of the opposed walls;
• and
• an elongate reveal member attached to the first elongate member, wherein the reveal member is disposed within the first member internal channel, and is attached to the first member by surface features in both the channel member and reveal member that cooperate with one another;

A method for using a channel screed within a wall surface comprising the steps of:

• installing a first screed member onto a structural surface, the first screed member comprising a base and opposed side walls extending upwardly from the base, the walls and base together defining a first member internal channel;
• applying a building material for forming the wall surface, wherein the building material is disposed around the first screed member and is in contact with an outside surface of the first member walls;
• installing a second screed member onto the first member, wherein the second member covers at least a portion of the internal channel, and is held in contact with the first member by cooperating surface features of the first and second screed members.
