Marble and granite are natural materials that are both beautiful, and very slippery and dangerous when wet.
The Nano-Grip process can make these surfaces safer when they are wet, however due to the differences discussed here, different treatment strategies are used.
More facilities are installing marble and granite floors today than years ago. There are two primary reasons for this:
1. The cost of marble and granite has come down now that these materials are being quarried in more areas of the world.
2. It is very durable. If cared for properly, marble and granite can literally last for centuries.
Marble is a soft stone made of metamorphic rock containing calcium carbonate. This means it will react, and potentially be damaged, if the solution used to treat it is too strong.
On the other hand, granite, made from igneous rock, is a very hard stone. Stronger solutions can be used on granite and, when used properly, will not damage its surface.
Scratch test: A “scratch test” helps identify floor hardness. It identifies how resistant a mineral is to abrasion. It is performed just as it sounds. Minerals are rubbed against each other; the one that scratches is softer than the mineral that caused the scratch.
Luster: This does not necessarily refer to how shiny the floor is, but more specifically how it reflects light from its surface. A highly polished stone floor will typically have a very high luster.
Cleavage: This term refers to how the mineral breaks or fractures. Some minerals, when they break, will have only one cleavage. Others may have two, three, or more.
Nano-Grip applicators should refer to their installation manuals for recommended dilutions and procedures.
