Recommended Applications
-
Open-Concept Living & Foyer Floors: Expansive 24" x 48" dimensions minimize grout lines, creating a continuous, airy floor layout that visually expands living spaces.
-
Full-Height Shower Walls & Bathroom Floors: Modern large-format format means fewer grout lines to clean in wet environments, resisting moisture and soap scum buildup effortlessly.
-
Fireplace Surrounds & Feature Walls: Delivers clean vertical lines and smooth chalky texture for modern hearths, accent walls, and commercial lobbies.
Installation & Handling Guidelines
⚠️ IMPORTANT: LARGE FORMAT TILE (LFT) INSTALLATION PROTOCOL
-
Subfloor Flatness Required: Large format tiles (24" x 48") require an exceptionally flat subfloor. Subfloor variation must not exceed 1/8" in 10 feet to prevent lippage and hollow spots.
-
Mortar & Back-Butter Technique: Use a polymer-modified Large & Heavy Tile (LFT) thin-set mortar (ANSI A118.4 / ANSI A118.11). Back-buttering the back of each tile with thinset is required to achieve 95%+ mortar coverage.
-
Lippage Control Systems: Always use a mechanical tile leveling system (clips and wedges) during installation to ensure flush, perfectly flat tile-to-tile edges.
-
Grout Joint & Offset: Maintain a minimum 1/16" to 1/8" grout joint. When installing in a staggered running bond, offset tiles by no more than 33% (1/3 bond) per TCNA guidelines.
Care & Maintenance
-
Routine Cleaning: Sweep or vacuum debris, then mop with warm water and a pH-neutral tile cleaner.
-
Stain & Water Resistance: Non-porous porcelain body naturally resists water absorption, household chemical stains, grease, and grime.
-
Zero Sealing Required: Unlike natural stone, glazed porcelain requires no sealer, polish, or special chemical coating on the tile face.
Design Profile
-
Aesthetic Inspiration: Soft Minimalist, Warm Organic, Contemporary Scandinavian, Architectural Modernism.
-
Visual Advantage: The creamy chalk color brightens interior spaces while the 24" x 48" format reduces visual clutter, producing smooth, continuous stone-look surfaces.
-
Complementary Finishes: Light natural oak millwork, matte black or brushed bronze fixtures, concrete accents, and warm linen textiles.
Frequently Asked Questions
Does Plus One Chalk porcelain tile require sealing?
No. Glazed porcelain is impervious to water and stains, so the tile surface does not require sealing. (Grout lines can be sealed if cementitious grout is used).
Can 24" x 48" 8mm porcelain tile be installed on shower walls?
Yes! Its 8mm thickness makes it lightweight enough for wall installation while providing a seamless, spa-like slab look with minimal grout maintenance.
Why is a mechanical leveling system recommended for this tile?
Because 24" x 48" tiles have a large surface area, leveling clips prevent "lippage" (uneven tile edges) during thinset curing, guaranteeing a completely flat floor or wall face.
