Top Polish Kit – Granite & Quartzite

The Complete Natural Granite & Quartzite Polishing Kit is a professional solution designed to repair, polish, restore and enhance natural granite and quartzite surfaces, delivering a factory-quality finish quickly, easily and efficiently.

Developed after years of collaboration with stone industry professionals and extensive testing by the NSI team, this kit contains the same products used daily by professional workshops to achieve superior polishing results on natural stone.

It is specifically designed for repairing granite and quartzite countertops, removing minor imperfections, restoring the original shine and producing smooth, professional-quality finishes.

The polishing process has been optimized for wet use, improving polishing performance, reducing heat generation and ensuring more consistent results. It can also be used outside the workshop by simply wetting the area to be polished.

Important: This kit is designed exclusively for natural granite and quartzite. It is NOT suitable for engineered quartz or artificial stone surfaces, including Silestone®, Compac® and similar materials.

Its simplified polishing process allows professional-quality repairs with fewer steps and less effort, making it the ideal solution for stone fabricators, installers and countertop repair specialists.
