A surfacing apparatus supported adjacent a substantially vertical surface of a structure for applying an even and uniform texture to the surface of the structure using a selectively adjustable force exerted on a texturing means to engage the surface of the structure. The surfacing apparatus is suited for horizontal and vertical movement in controlled prescribed paths under controlled and prescribed pressure from the adjustable tensioning means. The surfacing apparatus can include a texturing head that can be configured to conform to the contour of a curved work surface to apply an even and uniform texture thereon.
