Many commercial buildings are now installing stone floors such as ceramic tile, granite, marble and terrazzo. Although these floors may not need the frequent care that resilient tile floors need, they still need to be maintained regularly in order to keep the stone and grout looking good. If not maintained properly, the floor and grout will start to look dull and dirty.
We will recommend a floor care program that is safe for the type of flooring you have in your building. The program we recommend will depend on traffic levels and desired appearance.
Marble is a metamorphic stone and is one of the most expensive floor coverings made. Marble is a re-crystallized limestone and can be identified by the veins running through it. Marble is soft and scratches easily, and acid products will etch the floor.
Granite is an igneous stone and contains many different minerals such as quartz, feldspar and potassium. Granite is very hard, tough and durable, but it stains easily if not sealed. It must be sealed with a penetrating sealer.
Travertine is a sedimentary stone, which has a lot of holes in it and must be filled with a synthetic resin or cement based product. Travertine most often has a honed finish but will have a floor finish on it. If a topical coating is applied it should be a water-based finish and be specifically made for natural stone.
Slate is a metamorphic stone, which comes in common colors such as black, gray, and green. It will have many finishes such as sand, rubbed and honed. Slate is porous and should be sealed. It will often have floor finish applied as well.
Terrazzo was very popular in the 1950's and 1960's and we saw a comeback in the 1990's. Terrazzo is made of 30% Portland cement mixed with about 70% marble or granite chips. It is available in 12” x 12” and 4' x 4' squares. Terrazzo can be sealed with an impregnator sealer or finished with a topical product.
