Natural stone is beautiful. That is exactly why it needs proper protection.
In kitchens, bathrooms, hospitality spaces, and high-use environments, marble is exposed daily to acidic substances such as wine, lemon juice, coffee, and cooking oils. Over time, these can cause etching and staining that traditional sealers are not designed to prevent.
This is where RAKU™ and AZ Stone Restoration make the difference.
Developed in Italy using advanced nanotechnology, RAKU™ is an ultra-thin, professional-applied protective coating that forms an invisible, breathable barrier on the stone surface. It preserves the stone's natural feel and depth while delivering long-lasting protection.
On polished finishes, RAKU™ preserves clarity and reflection. On honed or matte surfaces, it provides a refined satin appearance. Unlike film or UV coatings, it does not sit on top as a plastic layer. Instead, it bonds directly to the surface, respecting the stone’s natural character.
Once cured, the RAKU™ coating is food-safe and non-toxic. It helps prevent liquids, bacteria, and contaminants from penetrating porous stone surfaces, making it especially valuable in kitchens, bars, and food-preparation areas.
RAKU™ helps protect against:
Etching
Staining
Scratching
Heat exposure
All while maintaining the integrity of the stone’s appearance.
What makes RAKU™ different
RAKU™ occupies a premium category within the stone protection market.
For discerning homeowners, designers, architects, and hospitality professionals who value both beauty and durability, RAKU™ offers Italian-engineered nanotechnology that protects marble and other precious stone surfaces without altering their look or feel.
Key features include:
- Nano-coating developed and tested in Italy
- Invisible, film-free finish
- Resistance to staining, etching, scratching, and heat
- Suitable for approved interior and exterior applications
- Can be applied on horizontal and vertical surfaces
- No sanding, UV lights, or finishing required after application
- Helps reduce long-term maintenance costs
RAKU™ can be applied to both new and existing marble surfaces. New installations can be protected immediately after proper preparation. Existing surfaces may first require professional restoration or refinishing to remove etching and staining before application, ensuring optimal performance and longevity.
AZ Stone Restoration is among the few certified providers in Arizona authorized to professionally apply RAKU™ in accordance with Marble Armour and Lantania standards.
Important to know
RAKU™ is designed to provide durable, long-lasting protection. It is not permanent and not maintenance-free. Like all high-performance systems, it works best when paired with proper care and regular maintenance, following the RAKU™ Care and Maintenance Guide.
RAKU ™is not sold to the public and is not a DIY product. It is applied exclusively by trained and certified professionals. Proper application, surface preparation, and curing are essential to achieving the expected results.

Arizona living means heat, sunlight, entertaining, and everyday use. When marble is part of your home or business design, protection should be part of the plan.
