Applying a variety of coverings to walls is an essential part of decorating residential and commercial structures. Paperhangers are trained workers that apply a variety of materials to walls, ceilings, and many other interior surfaces. Paperhangers typically need at least a high school diploma. Some paperhangers complete formal training programs through vocational and technical schools and others complete apprenticeship programs that combine classroom instruction and paid on the job training. Employment of paperhangers is expected to decline rapidly, decreasing 14% from 2008 to 2018. The increase in homeowners switching to cheaper wall covering alternatives will contribute to the employment decline.
