How to use this data: this is a general manufacturer performance reference for 20 mm porcelain pavers, primarily reflecting average production and matte/exterior-finish testing. It is not a product-specific certificate or a universal approval for every collection, finish, caliber, lot, installation system, or site condition.

  • No surface is slip-proof. Water, contaminants, slope, footwear, joints, maintenance, and site conditions affect real-world traction.
  • Use pavers from the same caliber and production lot where possible, especially across connected visible areas.
  • Product-specific test reports and current technical documents may be requested when a project requires documented values.
  • Dry-laid, pedestal-supported, rooftop, balcony, terrace, and other above-ground systems require project-specific review of support layout, reinforcement, wind, loads, drainage, perimeter restraint, and applicable codes.
  • Any cracked or damaged paver in an elevated installation should be isolated and replaced promptly.
  • Indiana Grey Select is listed by Aura as a 20 mm porcelain paver; confirm the exact finish, lot, installation method, and current technical documentation before final specification.
Installation & care

Protect the design through good planning.

Confirm base preparation, slope, drainage, joint layout, finish suitability, and perimeter details with the installer before ordering. Use only compatible cleaners and follow the current product, grout, and cleaner instructions; do not use hydrofluoric acid, sealers, waxes, or unapproved coatings.
