A TILER is a professional who specializes in the installation of backsplashes. They are responsible for measuring, cutting, and fitting tiles to create a backsplash that is aesthetically pleasing and structurally sound. They must also be knowledgeable in the use of various tools and materials, such as grout, sealants, and adhesives. Tilers must have an eye for detail and be able to work with precision to ensure that the backsplash is installed correctly.
