Waste granite powders as fillers in epoxy coatings: A case study in a car repair workshop

Epoxy coatings of floors are a very good solution for car repair workshops. Epoxy coatings provide the floor with resistance to oil, fuel, and grease staining. The floor surface is very easy to clean. To support sustainable development, a filler in the form of waste granite powder was added to the epoxy coating. In a car repair workshop, an epoxy coating of the floor was made according to the recipe previously developed in laboratory tests. The pull-off strength of the concrete substrate was tested before and after the mechanical treatment of concrete surface. The pull-off strength of the epoxy coating was also tested. The obtained results were compared with the laboratory results. It has been proved that the waste granite filler does not deteriorate the pull-off strength of the epoxy coating and thus its durability. The waste granite powder can be successfully applied as a filler in real epoxy coatings of floors.
