Italian RAKU Nanocoating — Built for San Francisco

RAKU by Lantania is a molecular nanocoating developed in Italy that permanently closes the pores of marble, onyx, quartzite, travertine, and limestone at the molecular level — creating a zero-porosity surface that resists etching, staining, and moisture without changing the stone's natural appearance or finish.

Natural stone in San Francisco faces specific challenges: the unique combination of climate, use patterns, and high-end finishes that make flawless stone maintenance both critical and difficult. RAKU's permanent barrier means the etching, staining, and porosity risks specific to this market are eliminated from day one — with a single one-day application backed by a 10-year warranty.

  • Zero porosity — liquid cannot penetrate the stone
  • Etch-proof — acids no longer damage the surface
  • Stain-proof — wine, oil, and cleaners wipe away cleanly
  • Food-contact safe for kitchen and bar surfaces
  • Heat resistant to 1,200°F
  • One-day installation — no operational downtime
  • 10-year warranty on every application
