An adjustable screed with a flexible body (suited for use in cut-out areas) or a rigid body (suited for use adjacent to wall-like structures), a horizontal adjustment mechanism for establishing a horizontal plane for the screed and for securely maintaining the horizontal plane, and a vertical stabilizing mechanism for attaching the screed to an external object whereby when one or more screeds are being attached to the external object, the screed is adjusted and aligned to a single horizontal plane, securely maintained at that horizontal plane, and the vertical stabilizing mechanism maintains the attachment of the screed to the external object and maintains vertical stability of the screed as horizontal adjustments are being made. |
