Atlantic Dark Grey Matte 12×24 Porcelain Tile Rectified
Understated and modern, the Atlantic Dark Grey Matte 12×24 porcelain tile brings a refined dark grey tone with a soft, low-sheen surface. The 12×24 format reduces grout lines for a streamlined look, while rectified edges help achieve tight, consistent joints across floors and walls.
Crafted in durable porcelain, this tile balances everyday practicality with design versatility—well suited for kitchens, baths, living areas, and commercial wall applications. PEI 3 wear resistance and a wet DCOF of 0.42 support reliable performance in interior spaces.
Planning is straightforward with 15.5 sq ft per box (8 pieces). Use this versatile field tile on its own or pair it with coordinating trims to create clean edges and cohesive transitions.

Installation Guide – Atlantic Dark Grey Matte 12×24 Porcelain Tile 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 appropriate for 12×24 tile.
- Plan the layout by dry-laying tiles to balance cuts and align grout joints; avoid narrow slivers at perimeters.
- Blend tiles from multiple boxes to distribute shade variation evenly.
- Select spacers and a joint width suitable for rectified tile; provide movement joints per TCNA EJ171 at all required locations.
Step 2: Tile Installation
- Use a polymer-modified thinset mortar approved for porcelain and the installation setting (floor or wall).
- Key mortar into the substrate, then comb with an appropriate notched trowel; back-butter tiles as needed to improve contact.
- Set tiles with a slight sliding motion to collapse ridges and achieve proper bond; target coverage consistent with ANSI/TCNA for the area of use.
- Use a leveling system when needed to help minimize lippage, especially with large-format layouts.
- Allow mortar to cure per manufacturer instructions before grouting or allowing traffic.
Step 3: Cutting
- Cut with a wet saw equipped with a premium diamond blade rated for porcelain.
- Mark and support cuts carefully to reduce chipping; ease sharp cut edges where they may be exposed.
- Drill openings with porcelain-rated diamond hole saws at low speed with adequate cooling.
Step 4: Joint Filling
- Choose a grout suitable for porcelain and the selected joint width; follow the grout manufacturer’s mixing and cure guidance.
- Pack joints fully, clean diagonally, and remove haze promptly with clean water and soft sponges.
- Use sealant (not grout) at movement joints and all changes of plane; protect the installation until grout has cured.
Step 5: Cleaning & Maintenance
- Clean routinely with a pH-neutral cleaner formulated for porcelain tile; avoid acids and harsh abrasives.
- Use entry mats and protective pads to minimize grit and scratching.
- Follow grout manufacturer recommendations for maintenance; seal cementitious grout if specified.
