Tile fasteners shall be spaced a minimum of what distance apart?

1. 2 inches

2. 3 inches

3. 4 inches

4. 1 inch

The correct answer is: 2 inches

The correct spacing for tile fasteners being a minimum of 2 inches apart is rooted in industry standards and best practices to ensure the proper bonding and structural integrity of the tile installation. This distance allows for adequate support and distribution of weight across the surface, minimizing the risk of tiles cracking or becoming dislodged over time. When fasteners are spaced too closely, it can create excessive stress on the tile and underlying materials, leading to potential failures. In addition, following the 2-inch spacing guideline aligns with recommendations from various manufacturers and building codes that are designed to maintain the durability and longevity of tiled surfaces. Proper fastening also contributes to the overall quality of workmanship involved in tile laying, ensuring that the finished product meets both aesthetic and functional requirements. Understanding these guidelines is essential for any contractor or builder to comply with regulations and deliver safe, reliable installations.
