An apparatus (6) for the removal of an excess layer (4) from building elements (2) made of cured lightweight concrete comprises a front tool (9) having edges (10) which are located at a certain depth under the top surface of the excess layer (4) and a rear tool (11) having an edge (12) located at a somewhat greater depth under said surface. Hereby the excess layer is planed off from the element in two stages when the element (2) is fed through the apparatus (6), while securing a smooth and plain surface (18) on the finished element. (Fig. 3). The front tool consists of a plurality of cutting elements spread along a line, and the rear tool consists of one continuous blade.
