As  the  amount  of  spent  coffee  grounds(SCG) generated after  manufacturing  coffee  increases,  a treatment plan is needed. Therefore, this study examined the properties of mortars incorporating SCG with and without water repellent coating. Results showed, the compressive strength, density and absorption ratio of a mortar incorporating water-repellent coated spent coffee grounds were improved. However, additional research is needed to reduce the W/B due to the separation of the surface layer and the deep layer of the test specimen and the destruction of the specimen.
