This finish must be completely removed and the terrazzo re-ground to open up its pores before tile installa- tion. When properly prepared with the right materials, it becomes an excellent substrate for a new tile surface. A qualified tile contractor is the best person to determine whether your existing tile installation is well bonded to the terrazzo. Tile-over-tile is a method in the Tile Council of North America’s TCNA Handbook for Ceramic, Glass and Stone Tile Installation, providing the bottom layer of tile is well bonded and properly prepared to accept the bonding materials for the new layer of tile. This can be done by scarifying or grinding the surface of the existing tile and/or by applying an appro- priate primer that will allow the new setting material to achieve a proper bond. Grinding the surface of existing tile can create a lot of dust and may release potentially hazardous particles into the air from the materials used in the glaze. It is best to have this work performed by a certified, experi- enced professional installer. Such an installer will also be familiar with the primers and setting mate- rials that will work best for this type of installation.
