FAQ

Q. What is the difference between marble and granite?

A. Although both are stone and they're quarried from the earth, granite and marble (marble's relatives - limestone, onyx, and travertine) are very different from each other. Granite is formed deep in the earth's mantle at extremely high temperatures, and is a very hard, resistant stone made of crystallized minerals. The marble family includes limestone, travertine, marble, and onyx. It begins as sediment; animal skeletons, shells, plant matter, and silt at the bottom of bodies of water. After millions of years this all solidifies into stone.

Q.
I have just purchased a house that has a marble hallway. The flooring is about 10 years old. I understand that it should be sealed to reduce staining and dirt from penetrating into the pores of the stone. What do I seal it with? It is also dull and needs to be polished. How do I polish it and with what?

A. After 10 years of foot traffic, a marble floor needs to be re-polished. If the original installation is good, you can get away with a two step restoration procedure; honing and polishing. If the original installation is bad (excessive lippage), then the floor must go through a three step restoration procedure; grinding, honing, and polishing. You need special equiptment that you won't be able to rent anywhere. You need proper grinding and honing attachments. As well you need a good quality polishing powder. Then most importantly, you need to know what you're doing!

Q.
What is the best way to clean marble and other stones?

A. The old rule of thumb is never to use anything you wouldn't use on your hands. Never use powdered cleaners or abrasive pads to clean your stone. Even "soft scrub" type cleaners contain pumice (powdered volcanic stone), which couls damage your stone countertops or floors. Never use any products which are acidic or alkali; this includes substances like ammonia or many household liquid cleaners such as Fantastic, Windex, or vinegar. We recommend using Clean & Shine or Primavera Floor Cleaner from the
Maiolo Products Stone Care Line.

Q.
I have a travertine dining table. It has become scratched and has some stains on it. Can I use vinegar to clean it?

A. Travertine is a calcareous stone and is sensitive to acidic cleaning. Be cautios. Vinegar and other acids will etch the finish of the stone and take the polish off. We recommend Clean & Shine from the
Maiolo Products Stone Care Line.

Q.
We have a commercial property which was recently renovated. We are not happy about how our floor is leveled. Is there any "tolerance for lippage" as a standard?

A. Lippage is a condition where the edges of the tile are not on the same plane with each other. What are acceptable industry standards? This has resulted in many conflicts, because what may have been acceptable to the installer was not acceptable to the owner, resulting in litigation or withholding payment to the subcontractor. Lippage should not exceed 1mm when setting square edge tile with narrow joints (3mm or less). More lippage can be tolerated when wider grout joints are used or when the tile doesn't have a square edge. Lippage should not exceed 1mm per 3mm joint width.

Q.
We inherited a marble coffee table. The marble had at one time been given a coat of clear varnish that has yellowed over time. So, we sanded off the varnish and now the marble is white and beautiful, but dull. Since we want to use this as a coffee table that people would be setting their glasses on, how do we: 1) Make the marble top shiny? 2) Protect the marble from glass rings? We already tried a spray marble polisher, and it didn't do anything...

A. There are no ways around it; you need to hire a professional. There is nothing you can apply onto/into it to protect it from "glass rings". Use a coaster all of the time. We once suggested a customer to have a piece of glass cutom-cut tp put on top of the marble. To minimize detrimental effect of staining, seal your stone with an impregnator.
We recommend using K.32 Citrus Based Stone Sealer from the
Maiolo Products Stone Care Line.

Q.
I would like to know how to hone an existing marble floor that is 50 years old but in good condition. It has never had a polish finish. There are many light scratches and worn areas that we would like to remove. If I hire a craftsman, what should I be aware of about their work and how do I judge an acceptable job?

A. We would recommend hiring a professional, such as Maiolo Marble Restoration. If the company does the job properly, you will know!
