Flint Walnut 12×24 Porcelain Tile Natural Rectified
Warm and refined, Flint Walnut 12×24 porcelain tile delivers a modern, matte look in a versatile rectangular format. Precise rectified edges support clean, consistent grout joints, while the natural finish offers a soft, low-sheen surface that pairs easily with a range of cabinetry and fixtures.
Built for everyday performance, this 9mm-thick porcelain combines durability with easy care. A PEI 4 wear rating and a wet DCOF of 0.62 make it a smart choice for residential floors and walls, as well as light commercial interiors. Frost resistance broadens design options to exterior vertical applications in freeze–thaw climates.
Planning is straightforward with 13.56 sq. ft. per box (7 pieces), helping you estimate materials confidently.

Installation Guide – Flint Walnut 12×24 Porcelain Tile Natural Rectified
Important Advisory
Always follow the tile manufacturer’s instructions, local building codes, and recognized industry standards (ANSI A108/A118 and TCNA guidelines). Ensure proper substrate preparation, movement accommodation, and waterproofing/drainage where required.
Step 1: Layout & Planning
- Verify the substrate is clean, dry, structurally sound, and flat within tolerances suitable for 12×24 large-format tile.
- Plan the layout by dry-fitting tiles and centering the pattern to avoid small perimeter cuts.
- Blend tiles from multiple boxes to evenly distribute shade and pattern variation.
- Use spacers appropriate for rectified tile and include movement joints per TCNA EJ171.
Step 2: Tile Installation
- Use a polymer-modified thin-set mortar approved for porcelain and large-format tiles.
- Key mortar into the substrate, comb with an appropriate notched trowel, and back-butter tiles as needed to improve coverage.
- Set tiles with a slight back-and-forth motion to collapse ridges and achieve the bond required by application (typically 80–95% coverage).
- Use a leveling system if needed to help minimize lippage on large-format installations.
- Allow mortar to cure per manufacturer instructions before grouting or allowing light traffic.
Step 3: Cutting
- Cut with a wet saw using a premium diamond blade rated for porcelain.
- Mark cuts carefully, support the tile fully, and ease sharp cut edges for exposed transitions.
- Drill holes with diamond-tipped bits at low speed, using water for cooling.
Step 4: Joint Filling
- Select a grout compatible with porcelain and the chosen joint width; follow the manufacturer’s mixing and curing directions.
- Pack joints fully with a rubber float, clean diagonally across the tile, and remove haze promptly with clean water.
- Use flexible sealants at movement joints and changes of plane; do not grout these areas.
- Protect the installation from traffic until grout has cured per manufacturer guidance.
Step 5: Cleaning & Maintenance
- Clean routinely with a pH-neutral cleaner suitable for porcelain tile; avoid acids and harsh abrasives.
- Use entry mats and felt pads where appropriate to minimize tracked-in grit and scratching.
- Follow grout manufacturer recommendations for maintenance and sealing of cementitious grout if specified.
