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