| Abstract Scope |
The reuse of granite waste in the manufacture of building paints is an alternative studied to contribute to sustainable development. Therefore, the objective of this study is to evaluate the influence of granite waste, acting as mineral filler, on the weathering resistance of soil pigment-based paints. To manufacture the paint samples, a mixture design of experiments was defined, varying the proportions of soil, waste and polyvinyl acetate resin (PVA). The weathering resistance test was performed based on the specifications of ASTM G7:2013. The paint film submitted to weathering was compared to the paint film protected from external agents. It was observed that the use of granite waste in soil pigment-based paints delays the appearance of pathological manifestations and reduces the color change of the product. Thus, it is possible to conclude that granite waste has a strong potential to be reused in the production of paints. |
