| Abstract Scope |
The consumption of ornamental stones has become expressive in the world and has spread widely as a coating material. Therefore, in order to overcome the problems observed in relation to mechanical strength associated with rocks, an epoxy-based resin was developed to waterproof them and maintain their strength. Therefore, in addition to verifying whether the resin promotes resistance gains, the possibility that it offers stain resistance was evaluated. To carry out the tests, four types were chosen whose commercial names are: Ornamental Yellow, Corumbazinho Gray, Ocher Itabira and Labrador Green, divided into polished and resined. After the test, lemon juice and steel wool were the staining agents that caused the most visible changes. In addition, it was observed that some resin materials had a greater loss of gloss compared to polished ones, making it clear that the resin did not waterproof the rock in terms of loss of gloss. |
