The problem of defaced acoustical ceilings in homes, apartments, offices, etc., is eliminated in a highly simple and economical manner. The ceilings are defaced as the result of the removal of decorative hooks which suspend plants, etc. In accordance with the present method, the unsightly hole and surrounding defaced region are effectively obscured by first removing a circular region of acoustical substance from the underlying wallboard surface, the circular region having as its center the hole formed by the decorative hook. Thereafter, a circular patch of acoustical material is applied to the wallboard surface, completely filling the circular region from which the acoustical material was removed. The result is such that it is difficult to ascertain what part is patched and what part is not. In accordance with the apparatus, a circular patch of acoustical material (or simulated acoustical material) is provided in combination with a tool of corresponding size. The tool has a central portion which fits into the hole in the ceiling, and blade portions which scrape from the wallboard surface the acoustical material at a precisely defined region corresponding in size to the patch.
