ABSTRACT:
A tool for applying plaster or other coating materials to a wall comprises a blade with a flat underside and a handle on its upper face, the ends of the blade being adjustably secured to a pair of cheek plates whose lower edges form skids for guiding the trailing edge of the blade at a selected distance from the wall surface to be coated. The front and rear edges of each cheek plate, engaged by slides attached to the blade, are inclined with reference to its bottom edge to maintain the blade at a small angle to the engaged wall surface. The slides of each cheek plate are interconnected by a yoke carrying a micrometric screw for varying the thickness of the coating by relatively displacing the yoke and the cheek plates.
