The RUBI sanding block in the shape of a prism is designed for repairing and cleaning up cuts or small defects and imperfections on the surface of tiles and glazes. The block is shaped for holding in the hand and comfortable grinding. It has two types of grain size. The rougher side is suitable for removing imperfections after cutting tiles. The finer side is suitable for removing scratches or cracks. For best results, we recommend using the sanding block wet.
