TAPERS/DRYWALL FINISHERS prepare unfinished interior drywall panels for painting by taping and finishing joints and imperfections.
Drywall consists of a thin layer of gypsum between two layers of heavy paper; it is used on walls and ceilings in most buildings today because it is faster to apply than plaster and gives a professional finish when completed.
Using the wide, flat tip of a special trowel, drywall finishers spread joint compound into and along each side of the joint between two hung drywall panels and use a paper tape to cover the seams between panels, resulting in a uniform and almost perfect surface.
