About Marble Tiles

Production

• Marble occurs naturally and is quarried all over the world. In the U.S., Vermont produces large amounts of marble, but many other states also quarry marble. In order to make the most of a piece of marble and keep costs down, tiles are cut to the smallest width that will work for the purpose without breaking. The tiles have to withstand shipping, handling and installation without cracks or breaks. The tile edges usually do not have a bevel but are cut square.

Discoloration and Staining

• Marble sometimes becomes discolored along the edge when tiles are cut at the installation site. The saw used to cut needs to have the blade cooled with water. This can stain the edges unless the water and blade are kept very clean. Marble also absorbs water and can temporarily darken. Only sealants and cleaners recommended by the manufacturer should touch the marble surface.

Installation

• A flat and carefully prepared surface makes installation successful. If the floor has uneven areas, the tile can crack after installation. The tiles should be checked before use for flatness and condition. Use a bonding material designed to work with marble. Light-colored marble should have special bonding material, since a dark color may show through after installation. Consider professional installation, since cracked tiles and improperly installed floors are costly to repair.

Care

• Porous marble absorbs spills and shows stains. Often the installers seal marble floors to protect the surface. Seal the grout even if the marble isn't sealed. Wall tiles serving as a backsplash behind a stove or sink should also be considered for sealant. Daily vacuuming keeps small pieces of dirt and grit from scratching the floor whether sealed or not. Clean spills immediately with marble cleaner and never use regular cleaners on marble. When mopping, use warm water.
