ABSTRACT:
A cement applicator for outside corners such as those used in dry wall construction which includes a container for the cement having an open front and a back wall which is moveable along tracks when pressure is applied thereto to force cement out of the front and into the corner. The tool also includes at least two wheels positioned to track along the edge of the corner to be finished and adjacent wipers which are biased to form an angle less than a 90.degree. angle therebetween about the wheels. The wipers include peripheral seals which in combination with the biasing action and the regulation of the tool position by means of the wheels finish the surface of the cement applied to the corner. The wipers may be of different lengths to provide for corners such as those found on stud walls or around windows.
