An automated trowelling system (10) for providing a smooth, even finish to one or both sides of a wall (12). The present system smooths wet surface materials such as concrete or plaster quickly and consistently with minimum manual intervention. Horizontal brackets (30, 32) on the wall (12) support a horizontally translating column (22) and an associated vertically reciprocating trowel (34). A first motor (28) propels the column (22) and trowel laterally along the wall (12), while a second motor (38) effects vertical motion. A forward scoop (42) removes excess wall finishing material ahead of the reciprocating trowel (34), and a nonreciprocating finish trowel (44) follows the reciprocating trowel (34) to provide enhanced finish to the wall (12). A processing unit enhances the ability of the system to operate with minimum manual intervention. Sensors provide input to the processing unit.
