<p>During construction or repair, two adjacent building outer walls are finished with a layer of plaster, each wall terminating at a common vertical corner. The application of plaster in the vicinity of the corner and the line of plaster along the corner itself, is defined by a right-angled vertical profile which is embedded in the plaster during the plastering operation. The profile incorporates elongated ridges which define the correct plaster surface limit. Also claimed is a commensurate hand tool for the shaping operation.</p> |
