The construction industry always calls for new concepts and techniques. From the adoption of the lean mentality philosophy in the 1990s, companies in the industry have been applying their principles and tools to the construction sites. The flow of value, and consequently logistics, is one of the most relevant and widespread within Lean Thinking, as it seeks to identify and eliminate waste along the entire value chain, from the raw material to the final customer. For this, it is necessary to manage the physical flows of people, materials and equipment at the construction site. There are few studies that address in a systemic way the possible gains in productive efficiency provided by the mechanization of the application of mortars in coatings, combined and integrated with the logistics management. Therefore, this work sought to evaluate the relationship between: logistics, productivity and costs of the Mortar Coating System, comparing two application processes: manual and with mechanical projectors. For this evaluation, it was necessary to use the tools of Lean Constrution: process diagrams, mapofluxograms, Unitary Ratio of Production - RUP, losses and cost of production of labor and global. The methodology is classified as a multiple case study, a descriptive research and uses of visits to the works, surveys and measurements in the field, documentary and in-situ evaluations, as well as management meetings. This study was carried out taking into account the context of the works of the metropolitan region of Goiânia, with the support and partnership of the Sinduscon-Go Construction Community. The work concluded that the mechanical projection represents a form of industrialization and rationalization of the productive process and is economically feasible, with reductions that can reach up to 13.07% of the overall cost of the internal lining of the enterprises surveyed. This viability is possible through the gain of productivity coming from an integrated management of the production by a well implemented logistics, and without loss incorporated in the thicknesses of the taliscas.
