Product Description

B‑Chem 5 Extra Polishing Powder is a high‑performance polishing compound formulated for marble and all calcium‑carbonate‑based stones. It is used as the final step in traditional polishing systems to achieve a deep, reflective gloss on marble, stone, and terrazzo surfaces.

According to the technical sheet, this powder is designed to be applied under a felt pad with just enough water to create a dense slurry. It polishes effectively by generating controlled heat on the stone surface — a key factor in achieving maximum shine. Using too much water slows the polishing reaction, while leaving the powder on the floor without rinsing may dull the finish, so proper technique is essential.

This product is widely used by stone technicians for restoring shine, removing light dullness, and enhancing the final gloss level after grinding and honing.
