Frequently Asked Questions



  • How much dust will be created during the restoration of my floor or countertop?
    • There is no dust created during the restoration process, because we use diamond abrasives, and water.
  • Water spots on my marble or travertine will not clean up, why?
    • They are not water spots, but etch marks in the surface of the stone caused by an acidic substance coming in contact with a calcium based stone. If the etch mark is not severe, it can be polished out or cleaned off with a little soap and water.  If the etching is more severe, you will need to have your stone professionally serviced.
  • How often will I need to have my stone professionally serviced?
    • That will depend on the degree of traffic the stone surface gets.  As a general rule of thumb, once a year for general maintenance of professional cleaning and sealing will help prevent permanent stains.   Full restoration ( Diamond grinding to remove scratches, stains, and etch marks) is needed when you see visible issues with your stone,  such as etching, wear patterns, scratches, or an uneven finish.  In the average home the full restoration process is needed approximately every 3-5 years if the stone is properly maintained.
  • My stone counters don't look as shiny as they did when they were installed, what can I do to make them look better?
    • Usually the answer to this is to look at the products with which  you are using to clean.  Many cleaning products will leave a residue which over time builds up on the stone surface and creates a film.  Often times consumers are told to use water and dish soap, this too will leave a soap film build up and mask the natural shine of the stone surface.  Using a proper cleaner will prevent this, and condition your stone correctly.  Give us a call if you have questions regarding the cleaner you are using or if the situation is more involved than that.
  • How do I prevent my stone in my entry way from getting scratched and damaged?
    • Mats or area rugs inside and outside an entrance will help to minimize the sand,dirt and grit that will scratch the stone floor.  Be sure that the underside of the mat is a non-slip surface, and is not made of rubber or latex.  Normally it will take a person 8 steps on a mat surface to remove sand and dirt from the bottom of their shoes.
  • Should I use waxes on my stone surface to protect it and make it shiny?
    • Absolutely not!  Waxes, and other topical coatings are one of the causes of the most severe damage that can happen to stone.  On the surface, waxes trap dust and dirt particles which cause scratches and dulling.  Below the surface of your stone are a series of interconnected pores and capillary structures, which allow for moisture vapor transmission that is crucial in allowing your stone to breathe.  Waxes and coatings block the natural vapor transmission process.  When the moisture gets trapped below the surface it can cause chemical and mineralogical changes within the stone.  This decay may be seen as pitting, spalling, flaking, and oxidation.  Also the look of a waxed stone is nothing compared to a naturally polished stone.
  • Stains in my stone surface will not clean out, are they now permanent?
    • Most stains that occur in a stone surface can be removed. Knowledge of the correct process, stain specific chemicals and application are very important, and can be the difference between removing the stain and setting it permanently.  There is not one chemical to remove all stains.  Give us a call if you have any questions regarding stains in your stone.
  • My cleaning company used a cleaner that contained and acid on my marble surfaces.  The marble was sealed, but the cleaner still caused the surface to dull, and there are small circles where the bottle was placed down.  What can be done to correct this?
    • Sealers (impregnators) are designed to protect against staining but cannot prevent etching (acid attacking calcium). Most often in a case like this the marble surface will need to be professionally refinished.
  • My stone surface was sealed, but glasses still leave dark wet rings, is this normal?
    • There is a big difference between the stone being sealed, and the stone simply having sealer applied.   There is a process involved in sealing natural stone that is more involved than using one sealer for all stones.  There is a reason that solvent based, water based, silicone based, resin based, and mineral based sealers exist. The Impregnating sealers used for your stone should be Based on the exact unique stone installed in your home, not just the stone type or species. The porosity of the stone should be checked in several areas before deciding which sealer to use.  When the sealer is chosen then a stone professional will know when the stone has accepted a proper amount of sealer.  Directions on sealer containers are a good starting point, but they are generalized, and cannot account for the porosity level of every stone.
  • Natural Stone Care DO'S and DON'TS
  • DO
    • Always use preventative cleaning measures
    • Always use a PH neutral cleaner, preferably a stone industry trusted name brand intended for natural stone.  These tend to have stone conditioners, and sealer reinforcement.

    • Use walk off mats to protect floors
  • DON'T
    • Do Not use any hard cleaners that contain acid on any natural stone surface
    • Do Not use use vinegar, bleach, ammonia or other general-purpose cleaners
    • Do Not use abrasive cleaners or alkaline cleaners not designed for natural stone
