Tile installation guide questions
Use the answers to prepare for an assessment and written estimate.
01Can new tile be installed over existing tile?+
Sometimes, when the existing assembly is sound, well bonded, clean, sufficiently flat, compatible, and approved for the selected system. Floor height, doors, appliances, transitions, and hidden conditions still need review.
02Do cracks in a concrete slab need repair before tile?+
Cracks and joints should be evaluated before installation. The appropriate repair or movement-accommodation approach depends on the crack, substrate, tile, setting system, and applicable installation requirements.
03What is included in tile-floor demolition?+
Confirm removal of tile, mortar or adhesive, underlayment, debris hauling, dust control, protection, and the method for approving substrate work exposed after demolition.
04What should a tile flooring estimate include?+
It should identify tile and quantities, layout, demolition, substrate preparation, membranes, mortar, grout, profiles, transitions, fixtures, cleanup, cure time, warranties, schedule, payments, and change orders.
05Where can I read general tile-industry installation information?+
The Tile Council of North America publishes technical FAQs. The installer should still follow the current requirements for the exact tile, setting materials, substrate, and project.
