Porcelain tile is a manmade tile. It can be unglazed, glazed, or honed to a high polish. Because of the composition of the body and how the tile is manufactured, the finished product is impervious, having less than 0.5% water absorption.
Due to the tile’s low absorption, setting materials specifically recommended for porcelain tile installation by the setting material manufacturer should be used. When in doubt and for more specifics, refer to TCNA (Tile Council of North America) The Industry’s guide for Installation Practices.
General maintenance and cleaning of porcelain tile will vary depending on the surface and soil load. General cleaning should be performed first by sweeping or vacuuming to remove loose soil or other surface contaminants, and then lightly damp mopping with clean water. Depending on the soil load, a more aggressive cleaning process may be required. This would include the use of a neutral cleaner or a general household cleaner, followed by a thorough rinsing.
