Abstract: A novel plaster application method includes the first step of applying the plaster in a plurality of parallel and spaced apart lines using a novel hand tool so that the upper edges of each plaster line define the plane of the final plaster surface. After allowing the plaster lines to dry and harden, the second step is to fill the spaces between the lines with more plaster forming the final plaster surface by raising the level of plaster to the plane of the final surface. More layers of plaster may be applied if needed. A serrated hand tool is proposed for aiding the plaster spreading which contains a plurality of generally triangular teeth with oval upper portions and blunt lower ends defining the distal edge of the tool. The new method allows a faster application of plaster in a construction practice with reduced consumption of plaster material.
