3. Stone surface step, edge and corner polishing, no color difference, high consistency, even width.
4. The floor tile surface is aligned with the step-by-step brick seams and paved firmly.
5. Baffle or water line should be set on the side of step to prevent stair side pollution.
6. The surface of the staircase kick line is smooth, the thickness of the prominent wall is consistent, the line is neat, and there is no color difference.
7. Kicking line can be laid in whole piece with smooth joints.
8. Kicking line can be in step with step arrangement.
