4246 Cement Masons Cement masons pour, shape, and smooth concrete to create surfaces, such as sidewalks. Terrazzo workers enhance walkways by mixing rock chips or other items in the fresh cement. The first step in preparing a site for concrete is for masons to set the forms that hold the concrete. The forms must be set to the proper depth and aligned.
Masons direct the pouring of the concrete and supervise the laborers who spread it.
Next they guide a straightedge across the top of the concrete to level it. Then masons smooth the concrete with a bull float, a long-handled tool. Finishers then press an edger between the forms and the concrete. They guide the tool along the edge to give the concrete slightly rounded edges. Next they use a tool to make grooves at specific intervals in the concrete.
