Red Seal Tilesetter Practice Exam

What is the first step when preparing a surface for tile installation?

1. Apply a primer

2. Clean the surface of dust and debris

3. Measure the area

4. Lay down the tiles

The correct answer is: Clean the surface of dust and debris

The initial step when preparing a surface for tile installation is to clean the surface of dust and debris. This is crucial because any contaminants like dirt, grease, or other residues can prevent the adhesive from forming a strong bond between the tile and the substrate. A clean, dry surface ensures that the materials adhere properly and that the tiles will stay in place over time, which ultimately affects the durability and appearance of the finished job. While applying a primer, measuring the area, and laying down tiles are important steps in the installation process, they are not the first actions to take. A primer may be applied after the surface is cleaned to enhance adhesion, measuring is essential for ensuring proper layout and tile sizing, and laying down tiles occurs only when the surface is thoroughly prepared and ready for installation. Skipping or neglecting the cleaning step could lead to issues later, such as tiles lifting or uneven placement. Therefore, starting with a clean surface is foundational for a successful tile installation.
