Glazed Ceramic Wall and Floor Tiles

The tile surface itself generally should be evaluated according to the manufacturer’s care and installation instructions rather than assumed to require sealing. Glazed surfaces can have different performance characteristics, while grout joints and installation materials may have separate maintenance requirements. Confirm the selected product’s technical documentation and consult the Product Department before specifying sealants or liquid-applied membranes.

No. Porcelain is a classification within the broader ceramic tile category and is distinguished by its specified characteristics, including water absorption requirements. Glazed ceramic products can have different classifications and absorption levels. Review the product’s technical data and applicable standards, such as ANSI A137.1, ISO 13006, EN 14411, and relevant ISO 10545 test results.

The main distinction is classification and technical performance, particularly water absorption. Glazed ceramic tile may be available in several classifications, while porcelain tile is manufactured and tested to meet its applicable classification requirements. Selection should also consider application, format, strength, abrasion, frost resistance, chemical resistance, and installation conditions rather than relying on appearance alone.

Glazed ceramic tile can provide durable performance when the selected product is appropriate for its application and installed correctly. Technical data may address breaking strength, surface hardness, abrasion, thermal shock, frost resistance, stains, and chemical resistance. Performance varies by product, classification, and format, so review the specific technical documentation before approving tile for walls or floors.

Glazed ceramic tile can be considered for shower wall applications when the selected product, installation assembly, and supporting materials are suitable for wet-area use. Confirm water absorption, surface characteristics, substrate preparation, adhesive or mortar compatibility, grout requirements, and waterproofing details. Liquid-applied membranes and other installation materials should be specified according to project requirements and manufacturer guidance.

Glazed describes a surface coating or finish applied to a ceramic tile, while glossy describes the level of surface sheen. A glazed tile may be glossy, matte, textured, or another finish depending on its design. When comparing products, review the finish, slip-related considerations where applicable, cleaning requirements, visual effect, and technical data for the intended wall or floor installation.
