Certified Stone Tile Installer (TCNA) The TCNA exam digs into installation substrate preparation, mortar composition, grout joint width calculations, and waterproofing membrane application?areas where missteps cascade into costly callbacks. You’ll need to distinguish between cement-based and epoxy systems, interpret ANSI standards for slope requirements, and understand how thermal expansion affects large-format tile layouts. Mastering these technical specifications separates installers who pass from those who fix problems later.
