Red Seal Tilesetter Practice Exam

Which type of tile is known for its durability and resistance to moisture?

1. Ceramic tile

2. Vinyl tile

3. Porcelain tile

4. Slate tile

The correct answer is: Porcelain tile

Porcelain tile is known for its exceptional durability and resistance to moisture, which makes it an ideal choice for various environments, including high-traffic areas and spaces prone to humidity, such as bathrooms and kitchens. The manufacturing process of porcelain tiles involves firing at higher temperatures and utilizing denser clay, resulting in a tile that is less porous than other types, including ceramic. This lower porosity means that porcelain tiles are less likely to absorb water, reducing the risk of mold and mildew growth. Their strength also makes them less susceptible to cracks and chips, contributing to a longer lifespan compared to other tile materials. In contrast, while ceramic tiles are also durable, they tend to be more porous than porcelain, making them less effective in moisture-prone situations without proper sealing. Vinyl tiles, although versatile and easier to install, do not match porcelain's durability and moisture resistance. Slate tiles, while attractive and also water-resistant, can be more prone to damage and require additional care over time. Thus, porcelain tile stands out as the best option for those seeking durability and moisture resistance.
