ABSTRACT:
A tool for spreading plaster, or the like, on wallboard surfaces which, in a first embodiment, includes a contoured surface having two end tip portions and a mid-portion contained in a plane spaced from the end tip portions. The tool includes a backing layer which gives structural integrity to the tool, and a flexible application-surface layer which projects beyond the outer edge of the backing layer. In use, the plaster is applied to the wallboard surface, and the projecting outer edge of the flexible layer is forced against the wall and pulled along to obtain a flat surface to spread the plaster out along the wallboard surface in an even and smooth manner to cover up cracks and tape. In a second embodiment, approximately half of the tool has a contoured surface, with the other half being planar. In this embodiment, the tool is used to distribute the plaster along the general wallboard surface area. This is accomplished by applying pressure to the planar portion to cause the plaster to spread outwardly between the curved portion of the tool and the adjacent wallboard surface. The tool is then used to smooth out that portion of the plaster positioned between the curved portion and the wallboard portion.
