At NBR, we’ve spent years searching for a surface protection solution that meets our exacting standards. After extensive experience with many anti-etch coatings—often plagued by high costs, peeling, and heat-resistance issues—we found our answer in RAKU. Unlike others, RAKU guards against etching and staining, resists scratching and heat, while preserving the natural elegance of stone. It’s the only anti-etch surface protection product we truly stand by.

We believe beauty shouldn’t come at the expense of compromise. That’s why we introduced RAKU: a next-generation protective coating that empowers property owners, designers, and their clients to select beautiful stones without worry. Invisible to the eye yet powerful in performance, RAKU preserves the integrity of natural stone—ensuring your vision remains as stunning as the day it was installed.

Subtle and durable, RAKU is invisible on polished surfaces and semi-matte on honed finishes. Engineered in Italy, this next-generation nano coating offers robust resistance against etching, staining, scratching, and thermal shock. It forms an ultra-thin, invisible layer that delivers real-world protection from food, drinks, and daily use—indoors or outdoors, on horizontal or vertical surfaces—wherever natural stone is installed.

Marble, travertine, limestone, onyx, and other calcium-based stones have long been favored for refined residential and commercial interiors—their luxury and timeless character are unmatched. Yet these stones are notoriously vulnerable to etching, staining, scratching, and heat damage from everyday elements such as citrus, wine, hard water, and cleaning products. At NBR, we frequently received requests for help with high-traffic areas such as bars, tables, kitchens, and bathroom countertops.
