ABSTRACT:
A tool for compressing and finishing the grout in joints between ceramic and mosaic tiles and the like. The tool includes a handle portion for gripping the device and a flexible yet resilient elongated shaft portion extending linearly therefrom. The shaft portion is bent about 20 degrees at a point approximately midway the length of the rod thereby forming two straight and distinct portions. The portion furthest from the handle, that is, the distal portion of the rod is placed atop the unhardened, exposed grout in the joints between tegular elements applied to a surface such that the entire distal portion is in contact with the grout material while the proximial portion of the rod assumes an approximately 20 degree angle with the surface. In this manner the user moves the tool along the grout joint while applying a desired amount of pressure such that the grout is compressed within the joints between tegular elements while it is also topically smoothed in an aesthetically appealing manner.
