Homeowners looking for a rustic or weathered look for their flooring often rely on terracotta tile, a durable and versatile material that many feel gives a home a warm and earthy feel. Terracotta tile comes in various finishes and has proven resistant to the growth of mold and bacteria. However, because it is very porous, terracotta tile absorbs moisture quickly, which means it must be sealed somewhat regularly to prevent cracking, discoloration and staining. It also must be sealed especially well when installed in a kitchen, as terracotta floor tiles are susceptible to damage from acids, alcohol, oils, and vinegar. Installation of terracotta flooring is labor intensive and is therefore best left to professionals.
