Large-format tile requires a flatter surface than small tile because each piece spans a larger area. The installer may need to flatten the substrate, back-butter the tile, use large-format mortar, and use suitable lippage-control tools. Patterns should be planned before cutting, especially with strong veining or directional graphics.

Key considerations

  • surface flatness
  • bond strength
  • appearance retention
  • large sizes
  • fewer joints
  • continuous visuals
