What RAKU Protects Against

RAKU exists for the way kitchens actually get used. These are the everyday incidents that mark natural stone counters, and the coating stands between them and yours.

RAKU Compared to Standard Sealing

RAKU is a protective coating that bonds to natural stone and forms a hard protective layer on the surface, applied by a certified two-person team. A standard impregnating sealer soaks into the stone and buys you wipe-up time. That difference is the whole decision.

Which One Fits Your Counter

Where RAKU Can and Cannot Be Applied

RAKU is for natural stone countertops. Marble, travertine, limestone, quartzite, and onyx are all candidates. It is not applied to quartz, porcelain, or concrete, and if that's your counter we'll tell you up front and save you the estimate visit. A clear no here is how you know the yes means something.

RAKU Before and After

Ask us to run a water-bead test on your own counter when we come out. It takes a minute and it shows you what the coating actually does better than any photo.

How the Coating Goes On

Every RAKU job starts with testing, not coating. Stone holding too much moisture will not bond correctly, and a bad bond is a failed coating, so we test the slab first and coat only when the stone is ready. The application is handled in place by a certified two-person team, and you get exact back-in-service timing before the job is booked.

The RAKU Warranty

Every RAKU application carries a ten-year warranty against etching, covering both product and labor. We walk you through the written terms before any work begins.

RAKU for Commercial Stone

Restaurant bars, hotel vanities, and office reception stone see more use in a month than most kitchen islands see in a year, which is exactly the case for a bonded protective layer.

Voices of Satisfaction

Stone Care of Arizona did an awesome job rejuvenating our travertine floors. They provided a professional estimate with many options and the crew that did the work was awesome. The floors look great and they made the grout look like new. We will use them every time in the future to keep these stone floors looking great. Thanks for the work!
Jason Gmeiner
Wow!  One of the best companies we have worked with.  Our limestone floors look incredible.  Showed up on time, great people, and the project turned out exceptional.  Michael the owner is first class and actually works on the job, not typical in the trades.  So not your sell it and then send an inexperienced crew to do it.  I wasn’t surprised when I went to do a review and saw they had 121 5 star Google reviews.  Also educated us on how to keep them maintained. Only one choice for our future needs, Stone Care of Arizona!
Nick Hoffman
If you are looking for a thorough, attentive, service look no further. Michael, Pravin, and the maintenance staff were punctual and their work was meticulous. This company's standards of service are very high. I hope to establish a working relationship with Michael for my future maintenance needs.
Janet Stanton
It was an honor meeting Michael Morrow with Stone Care of Arizona, Arizona Stone Care Experts. Michael came out to refurbish our fireplace as it had a few nicks and damage to the existing stones. He brought our fireplace back to life with his incredible craftsmanship! We would highly recommend this company due to their professionalism, craftsmanship & incredible customer care. Thank you again Michael for helping us out!
Maggie Statzer
We used Stone Care of AZ to clean, hone and refinish our marble tile floor, as well as paint and seal the dingy grout. They exceeded our expectations. The owner Michael was professional, responsive and extremely knowledgeable. Andre and Josh were great as well. When Andre said they wanted us to be 100% satisfied it wasn’t just lip service.  My only regret is we didn’t use them years ago. Thanks guys!

We had our travertine floors cleaned, repaired and polished by Stone Care of Arizona.  The two technicians (Joe and Joshua) that did our floors were polite, professional and knowledgeable. They went above and beyond to make sure we would be happy with the end result. They worked tirelessly for two days and we are very pleased with the end result.  They gave new life to our old, dull and dirty travertine!

Helmut Reda
Stone Care of Arizona cleaned and applied a coating to our Saltillo tile floors. Josh and Mario did a fantastic job and were neat, courteous and professional. We had some issues with the grout (which was not included in the original scope of work) but Michael, the owner, came out two times to resolve them to our complete satisfaction -- he really went above and beyond. After 40+ years as the owner of a remodeling company, I appreciate this level of service which today is all too rare.

HIRE THEM! Michael and his team earned every single piece of this five-star rating. Service was fantastic, pricing was fair, worksmanship was excellent. My expectations were exceeded, and that is really the reason for this review.

We had the company out 6 months ago to clean our Saltillo tile. 6 months later it still looks as good as the day they did it. Excellent work! Stone Care AZ as earned our referral, and all repeat business.
