Red Seal Tilesetter Practice Exam

What should be the first step in a tile installation project?

1. Applying adhesive

2. Preparing the substrate

3. Measuring and cutting tiles

4. Grouting the tiles

The correct answer is: Preparing the substrate

The first step in a tile installation project is preparing the substrate. This step is crucial because a stable and clean substrate is essential for achieving a successful tile installation. If the surface is not properly prepared—meaning it is clean, dry, and level—tiles may not adhere correctly, leading to issues such as cracking, lifting, or uneven surfaces over time. Proper substrate preparation might include cleaning the area, repairing any damages, ensuring that the surface is level, and, if necessary, applying a primer or underlayment that is compatible with the adhesive and tile being used. Ensuring that the substrate is adequately prepared lays the groundwork for the rest of the installation process, contributing to the overall durability and appearance of the finished tiling.
