Tile flooring can be glazed or unglazed. Glazed tile is smooth and highly polished, while unglazed tile has a more natural, textural finish. Though tile is tough and durable, glaze can be damaged by wear-and-tear, or in older homes, lose its sheen over time. Reglazing returns glazed tile to its original, high-gloss appearance, transforming dull floors and restoring their beauty (while boosting the value of your home). Since it can be challenging, the reglazing process should be handled by an experienced professional.
