Natural Stone

When dealing with interior stone or exterior stone, the main factor that affects marble damage or erosion is the amount of acids that the stone may encounter.

With interior stone, the stones, markings, and problems can generally be subdued and minimalised with careful cleaning.

On the contrary, exterior stone, such as walls and bars, if left uncleaned, untreated, or simply not given the proper maintenance attention, may require hard stone stain removers along with a mixture of different buffs to get the deep stains and scuffs or markings out of the stone.

There are many different types of stone that can be used to enhance a luxurious style and grandeur feeling. There are generally two different categories that stone is put into based on their composition. These two different stones are Siliceous stone and Calcareous stone. The type of stone and where it is located are important factors to consider when cleaning and restoring your stone to its former glory.



A siliceous stone is composed mainly of silica or quartz-like particles. This type of stone is known to be tougher than calcareous stone. This tough stone is more resilient to most etching and staining, which is nice if your stone is located in a high traffic area of the yacht. Siliceous stone is considered very durable and relatively easy to clean. Unlike a calcareous stone, it is safe to use “mild” acidic cleaning solutions on an occasional and infrequent basis as it can handle a much heavier dose of cleaning styles.
Common types of Siliceous stone include:

  • Granite
  • Slate
  • Sandstone
  • Quartzite
  • Brownstone
  • Bluestone


Calcareous stone is a softer stone than siliceous and requires quite a bit more care when cleaning or restoring it.
Common types of calcareous stone include:

  • Marble
  • Travertine
  • Limestone
  • Onyx

Composed mainly of calcium carbonate, this type of stone is very sensitive to cleaning solutions that contain acidic or alkaline value. Additionally, calcareous stone tends to be a bit easier to scuff, stain, and scratch, so it is important that you identify which type of stone you have before applying harsh chemicals to the stone’s surface as you don’t want to do permanent damage on your precious marble!
