What must be done before installing tiles over an old floor?

Replace the entire flooring
Inspect and prepare the existing surface for adhesion
Apply a new layer of adhesive
Measure the existing tiles

The correct answer is: Inspect and prepare the existing surface for adhesion

Before installing tiles over an old floor, inspecting and preparing the existing surface for adhesion is essential. This step ensures that the surface is clean, level, and free of cracks or loose material. By assessing the condition of the old flooring, a tilesetter can determine if it is suitable for tiling and identify any necessary repairs or preparation needed to create a strong bond between the new tiles and the existing surface. Preparation may include cleaning the surface to remove dirt, grease, or wax, which can hinder adhesion. It may also involve leveling any uneven areas and fixing any structural issues to ensure stability. Proper preparation is vital because inadequate surface conditions can lead to tile failure, such as cracking or peeling, compromising the integrity and lifespan of the new installation. Therefore, this step is critical to achieving a successful and durable tile installation over an existing floor.
