Baltimore Gris 12×24 Porcelain Tile Natural Rectified
Refined and versatile, Baltimore Gris in a 12×24 format brings a clean gray tone that suits modern and classic schemes alike. The natural (matte) surface offers a soft, low-sheen look that layers comfortably with wood, metal, and stone accents.
Crafted in durable porcelain with precise rectified edges, this tile supports crisp, consistent joints for polished results on walls and floors. A PEI 4 wear rating provides robust everyday performance in residential spaces and select light commercial interiors, while frost resistance opens possibilities for exterior facades in freeze–thaw climates.
Use Baltimore Gris as a calm, foundational field tile or combine it with complementary materials to create subtle contrast and architectural interest throughout kitchens, baths, living areas, and feature walls.

Installation Guide – Baltimore Gris 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). Verify substrate suitability, movement accommodation, and waterproofing/drainage where required.
Step 1: Layout & Planning
- Confirm the substrate is clean, dry, structurally sound, and flat within industry tolerances for tiles of this size (12×24).
- Plan the layout by dry-laying tiles and centering the design to avoid sliver cuts at perimeters and focal areas.
- Blend material from multiple boxes to distribute any shade variation evenly.
- Select 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 tile.
- Key mortar into the substrate, then comb with an appropriate notched trowel; back-butter tiles as needed to improve bond.
- Set tiles with a slight back-and-forth motion to collapse ridges and achieve coverage consistent with industry requirements for the area of use.
- Use a tile leveling system if needed to help control lippage on 12×24 installations.
- Allow mortar to cure per manufacturer instructions before grouting or permitting light traffic.
Step 3: Cutting
- Cut with a wet saw using a premium diamond blade designed for porcelain.
- Mark cuts carefully and support the tile fully to minimize chipping.
- Lightly ease exposed cut edges where appropriate for safer, smoother transitions.
Step 4: Joint Filling
- Choose a grout compatible with porcelain and the selected joint width; follow manufacturer mixing and cure guidelines.
- Fully pack joints with a rubber float, clean diagonally, and remove residual haze promptly with clean water.
- Use appropriate sealant at changes of plane and movement joints—do not grout these areas.
- Protect the installation from foot traffic until grout has cured per manufacturer guidance.
Step 5: Cleaning & Maintenance
- Clean routinely with a pH-neutral cleaner suitable for porcelain; avoid acids and harsh abrasives.
- Use entry mats and furniture pads to help limit tracked-in grit and scratching.
- Follow grout manufacturer recommendations for maintenance; seal cementitious grout if advised.
