A drywall finisher is a construction worker that applies drywall or similar materials to walls, ceilings, and building partitions. In this job, you also fasten premade drywall panels to the interiors of rooms, finishing or taping joints to prepare surfaces for final finish work. The surfaces can be either plain or decorative. You typically apply drywall on interior walls, but it can be installed on the exterior of buildings as well. You should know how to read blueprints and be comfortable measuring and cutting the heavy panels for installation. This position involves duties such as spreading plaster and spackle, especially to cover nail holes, sanding surfaces after applying two or three coats of compound, and using equipment such as a lift to install panels on ceilings safely.
