SURFACE-PROTECTIVE GRAVE STONE AND SURFACE PROTECTION METHOD OF GRAVE STONE

Japanese Patent JP3810487

B2

PROBLEM TO BE SOLVED: To retain the beautiful surface of a grave stone which are not stained with ease and which are not chemically eroded, for a long time, by covering the whole surface with a protective skin having siloxane bonds. SOLUTION: The surface of a lower base stone 1, an incense burner 2, a middle base stone 3, a water bowl 4, an upper base stone 5, and a tombstone 6 constituting grave stones, is sufficiently washed and dried. Subsequently, a surface-protective agent chiefly made of a siloxane condensation product is applied by a spray gun or the like on the whole face including the bottom face of the constituting members 1-6 to form a surface protection skin film after curing at the normal temperature. Since the protection skin film coating the surface of grave stones contains siloxane bonds in the molecular structure, it is chemically inert and hence, excellent in anticorrosiveness, water-repellent effect, and water-imperviousness. As a result, it prevents oxidizing chemical substances in rainwater from eroding the surface of the grave stones. Even if they are stained, the stains can be easily removed by washing. Accordingly, the surface of the grave stones can be beautifully retained for a long time.
