What is the recommended depth for grout joints when setting quarry tile on fresh set mud?

• A. 1/2 inch
• B. 1/4 inch
• C. 3/8 inch
• D. 3/4 inch

Answer: (B)

The recommended depth for grout joints when setting quarry tile on fresh set mud is typically 1/4 inch. This depth allows for sufficient grout to fill the joint effectively, providing stability and flexibility while ensuring a good bond between the tiles. A 1/4 inch joint is also practical for managing movement and accommodating any slight imperfections in the tile edges or surfaces. Using a grout joint that is too deep, such as 1/2 inch or 3/4 inch, can lead to issues with the grout cracking or shrinking as it dries. Additionally, a joint that is too shallow, like 3/8 inch, may not adequately fill the space and could result in tiles shifting or loosening over time. Therefore, 1/4 inch is the optimal choice for performance and durability in installations of quarry tile.
