Plus One Plumb 12" × 24" Matte Porcelain Tile

Product Overview

Plus One Plumb 12" × 24" Matte Porcelain Tile captures the understated character of poured concrete in a durable, easy-care porcelain surface. Its cool gray Plumb coloration, subtle tonal movement, and soft matte finish create a clean architectural foundation for industrial, contemporary, minimalist, and transitional interiors.

Advanced inkjet printing produces approximately 8–10 distinctive faces, reducing repetitive patterns across larger installations. Rectified edges support clean alignment and controlled grout joints, while the tile’s PEI 4 rating makes it suitable for residential floors and appropriate medium-commercial applications.

Technical Specifications

Installation and Handling Guidelines

Important: Current Production Is 8 mm Thick

The manufacturer identifies this product as having been replaced by an 8 mm version. Confirm that all cartons belong to the same thickness, caliber, shade, and production lot before installation.

• Open several cartons and blend tiles to distribute the V2 tonal movement and 8–10 printed faces naturally.

• Install over a flat, clean, dry, and structurally sound substrate.

• Use a polymer-modified mortar meeting ANSI A118.4 or A118.15 and approved for porcelain tile.

• Directionally trowel the mortar and back-butter tiles where necessary.

• Achieve at least 80% mortar coverage in dry interior areas and 95% coverage in wet or exterior installations.

• For offset layouts, limit the running-bond offset to approximately 33% unless tile flatness has been evaluated and the installer approves another pattern.

• Rectified edges do not permit a grout-free installation. A joint of approximately 1/8" is commonly appropriate, but the final joint must account for actual tile variation and project requirements.

• Install shower applications over a complete waterproofing system. Sealer does not replace waterproofing.

• Incorporate perimeter and field movement joints according to TCNA EJ171 and applicable construction standards.

• Wet-cut with a porcelain-rated diamond blade and follow crystalline-silica safety requirements.

• Order approximately 10–15% additional material for cuts, breakage, layout selection, and future repairs.

Care and Maintenance

• Clean with warm water and a neutral-pH porcelain-tile cleaner.

• Use a soft cloth, mop, or non-abrasive nylon brush.

• Avoid waxes, oily soaps, harsh abrasive cleaners, and products that leave a slippery film.

• Rinse detergent residue thoroughly, particularly in wet and commercial areas.

• The porcelain surface normally does not require sealing.

• Cement-based grout may require sealing according to the grout manufacturer’s instructions.

Shade Variation

Plus One Plumb carries a V2 shade-variation rating. Slight differences in gray tone, surface movement, and printed concrete detail should be expected. Blend material from multiple cartons instead of installing one carton at a time.

Frequently Asked Questions

Is Plus One Plumb genuine concrete?

What is the current tile thickness?

The current product listing identifies the original version as replaced by an 8 mm production version, approximately 5/16" thick.

Is the tile rectified?

Yes. Its mechanically finished edges support clean alignment and controlled grout joints, but the tile should not be installed without grout.

Can it be used on floors?

Yes. Its PEI 4 wear rating supports residential floors and appropriate medium-commercial or light-institutional applications.

Can it be installed in a shower?

It is suitable for shower walls when installed over an approved waterproofing system. Confirm slip-resistance requirements before using it on a shower floor.

Does Plus One Plumb require sealing?

The porcelain surface normally does not require sealing. Cement-based grout may require a penetrating grout sealer.

Will every tile look identical?

No. The product has V2 variation and approximately 8–10 distinctive printed faces, creating subtle differences across the installation.
