How to use this data: this is a general manufacturer performance reference for porcelain tile, primarily reflecting average production and matte-finish testing. It is not a product-specific certificate or a guarantee for every color, finish, caliber, lot, installation, or use condition.

Confirm the exact collection, finish, caliber, shade, lot, and intended application before ordering.
DCOF classifications do not make any tile slip-proof. Slope, drainage, contaminants, footwear, maintenance, grout joints, and site conditions affect traction.
Use tiles from the same caliber and production lot in visually continuous areas whenever possible.
Product-specific laboratory reports may be requested when a specification or commercial project requires documented values.
The selected product is Essence Montauk Black; confirm current technical documentation for this exact selection and finish.

Optional Grip finish

Enhanced-traction 9 mm tile performance.

Available for this selection in 12" x 24", 24" x 48", 0.35" (9mm). Available by project; confirm current lead time with Aura Stone.

Grip finish is a 9 mm porcelain tile option—not a universal substitute for a 20 mm paver. It can support exterior and wet-area design where the exact collection, format, substrate, bonded installation system, drainage, slope, and project conditions are suitable.

No tile surface is slip-proof. Water, contaminants, footwear, slope, grout joints, maintenance, and site conditions affect traction.
Confirm that the exact color and size are offered in Grip finish before ordering; Grip availability is collection-specific.
Use the 20 mm paver where the selected dry-laid, pedestal, gravel, sand-set, or other installation method requires the thicker paver format.
Product-specific laboratory reports and current technical documents may be requested for specification-driven projects.
Essence Montauk Black is currently listed in Grip finish at 12" x 24", 24" x 48", 0.35" (9mm).

Installation & care

Protect the design through good planning.

Confirm substrate preparation, setting material, grout joint, movement joints, trim conditions, and wet-area requirements with the installer. Use compatible porcelain cleaners, remove grout residue promptly, and do not use hydrofluoric acid, waxes, sealers, or unapproved coatings.
