Flattening powder made of silicon carbide granules for flattening/straightening and cleaning of grinding stones. Both natural and synthetic grinding stones become hollow on the working surface over time during grinding, resulting in an inward curvature. The dressing powder is used to create or maintain a flat/straight surface. The correcting powder is suitable for Japanese water stones with a grain size of 2000 and above as well as soft-bonded natural stones (e.g. Belgian chunk/coticule). Not suitable for artificial ceramic stones, Arkansas stones and diamond grinding plates. Apply a small amount of powder to a hard and smooth surface, such as a thick safety glass, polished marble or granite slab. Slurry the powder with water. Now rub the grinding stone that you want to dress with circular movements against the base slurried with powder until the desired result is achieved. Plastic bottle with 230 g powder.
