Differentiating Between Glazed and Unglazed Porcelain Tiles

Porcelain tiles can be found in two distinct finishes: glazed and unglazed. The glazed variety is characterised by a protective coating that is fused onto its surface, enhancing its resistance to stains and providing a diverse array of aesthetic options. Conversely, unglazed porcelain features a more natural, matte finish, which is prized for its slip resistance and durability, making it an ideal choice for high-traffic areas. While glazed tiles typically do not necessitate sealing, unglazed tiles, due to their increased porosity, require regular resealing to shield against moisture absorption and staining. Understanding these differences is essential for homeowners to make informed decisions about their flooring.

Understanding the Key Differences Between Ceramic Tiles and Porcelain Tiles

While often used interchangeably, ceramic and porcelain tiles have several critical differences in terms of density, water absorption, and overall durability.
