A tile is a small, manufactured piece of hard-wearing substance such as clay or stone used for covering roofs, floors and walls. Roof tiles are prepared mainly to keep out rain, and are traditionally made from locally available materials such as clay, slate and wood. Modern substances of construction such as concrete and plastic are also used. Several clay tiles have a waterproof glaze. These are prepared of stone or clay. Clay tiles might be painted and glazed. Small tiles might be laid in patterns to form mosaics. The tiles are generally laid on a bed of sand, with cement sometimes added for extra strength. The spaces between the tiles are finally filled with a mortar mixture. These are generally ceramic, but other materials such as mirrored glass or polished metal can be used. Wall tiles are generally glazed, and often patterned by painting or embossing. Modern wall tiles are set to a wall using a synthetic tile adhesive. The spaces in between the tiles are filled by means of fine cement called grout, which is rubbed smooth before it hardens.

Ceramic tile:

Ceramic tile is ablaze in a kiln and then cooled at varying degrees of temperature and humidity. This development and reduction can cause the tiles to vary in size, sometimes by a 1/4" or more. Most ceramic tiles on the marketplace will have some variation in size but accept nothing more than a 1/8" margin of difference. Ceramic tiles by means of bright reflective surfaces are not recommended for floors as they can pose a slip hazard and have poor abrasive resistance.

Conclusion:

Ceramic tile installed in external locations must be able to withstand freeze/thaw conditions meaning they should have an absorption rating of 3% or less. These types of tiles are generally very dense, have greater impact resistance, and increased breaking strength. Install them using a premium quality, latex modified thin set mortar. Even though there are no industry standards, most ceramic tile is rated for use by the Porcelain Enamel Institute (PEI) abrasion test and is recommended by the American Society Testing Materials (ASTM). PEI ratings measure the wear resistance of the tile surface.
