The term FLOOR INSTALLER can be summarized as a person who specializes in the installation of floors. A TILER is a type of floor installer who specifically works with tiles, which are thin, flat pieces of material such as ceramic, stone, or glass, used for covering surfaces. Tilers use specialized tools to cut and shape the tiles, and then apply adhesive to the surface before laying the tiles in place. They also grout the tiles to ensure a secure fit.
