Nevada C-20 Tiling Standards Practice Test 2025 – Complete Exam Prep

Proper substrate preparation is critical to the success of tile installation because it directly impacts the adhesion between the tile and the surface beneath it. A well-prepared substrate is typically clean, level, and free from any contaminants, such as dust, grease, or moisture. This creates an ideal surface for tile adhesives or mortars to bond effectively.

When the substrate is not adequately prepared, issues such as cracks, uneven surfaces, or tile lifting can occur over time. These problems arise because inadequate bond strength can lead to the failure of the tile installation. Cracks may develop as the substrate shifts or settles, and uneven surfaces can lead to tiles breaking or being susceptible to water damage. Therefore, ensuring proper substrate preparation is essential for achieving long-lasting, aesthetically pleasing tile work that meets industry standards and performance expectations.

Other choices do not address the critical nature of adhesion or the overall performance of the installation. Weight reduction, cleaning simplicity, or material costs are important considerations but are secondary to the necessity of a stable and properly prepared surface for a successful tile project.
