How Are Tiles Graded? Understanding Tile Grades and Ratings

Learn how tiles are graded by durability, water absorption, and slip resistance to choose the best tile for walls and floors.

192 views

Tiles are graded based on factors like durability, water absorption, and surface wear. Commonly, tiles are divided into Grade 1 (best quality for walls), Grade 2 (good for both walls and floors), and Grade 3 (suitable mostly for walls). The coefficient of friction (COF) also matters for slip resistance, especially in wet areas. Look for industry standards like PEI ratings to ensure you choose the right tile for your needs.

FAQs & Answers

  1. What do tile grades mean? Tile grades indicate the quality and best use of tiles, such as Grade 1 for walls, Grade 2 for floors and walls, and Grade 3 mainly for walls.
  2. What is the PEI rating in tiles? PEI rating measures a tile's durability and resistance to surface wear, helping determine suitability for different applications like floors or walls.
  3. Why is the coefficient of friction important for tiles? The coefficient of friction (COF) indicates slip resistance, which is crucial for safety, especially on floor tiles in wet or high-traffic areas.
  4. Can I use Grade 3 tiles on floors? Grade 3 tiles are generally recommended only for walls due to lower durability; they are not suitable for floors.
