Porcelain is often suitable outdoors because of low water absorption, but not every finish or product is approved for every exterior application. A covered porch, vertical wall, pool deck, and uncovered patio create different requirements. The substrate, drainage, slope, mortar, grout, movement joints, and sealant must also be exterior rated.

Key considerations

  • freeze-thaw resistance
  • slip resistance
  • water resistance
  • exterior-rated options
  • multiple finishes
  • indoor-outdoor coordination
