Description
CLKer Renzo Noir 12×12 — Premium Rectified Porcelain Tile from Spain
The CLKer Renzo Noir 12×12 is a true black field in a rectified 12×12 format, a size that has come back strongly for compact floors, produced in Alcora, Castellón by the Spanish manufacturer CLKer. Supplied 14 pieces to the carton at 13.75 square feet, this Spanish porcelain tile is stocked at Procida Tile in Deer Park, NY for contractors, designers and homeowners anywhere in the United States.
About the Renzo Collection
The Renzo collection is a rectified glazed porcelain series from CLKer in 30×30 cm, packed 14 pieces to the carton. Rectified edges are mechanically squared after firing, which allows minimal grout joints and a tighter, more continuous field than a pressed-edge tile of the same size. Renzo is supplied in two high-contrast colourways, Noir and White.
Installation & Applications for CLKer Renzo Noir 12×12
The 12″x12″ (30×30 cm) rectified square suits powder rooms, entryways, mudrooms, compact kitchen floors and shower walls, where a large-format tile would demand excessive cutting. Rectified edges allow joints as tight as 1/16″ for a near-continuous field, though 1/8″ is more forgiving over an uneven substrate. Set on a flat, properly prepared substrate with a C2-class modified thinset, and pull from several cartons at once to even out any tonal drift between boxes.

Design & Coordination Tips for CLKer Renzo Noir 12×12
The CLKer Renzo Noir 12×12 is a solid-colour rectified square, which makes it the easiest tile in this range to coordinate: it works as the quiet floor under a patterned wall, or as a graphic checkerboard when paired with its opposite colour in the same collection. It sits well with white walls, pale timber and brass or warm-toned metal. With rectified edges you can push joints down to 1/16″ for a near-seamless field, or open them to 1/8″ with a contrasting grout for a deliberate grid.
Care & Maintenance
Glazed porcelain never needs sealing. Sweep or vacuum grit regularly and damp-mop with a pH-neutral tile cleaner; avoid acidic or bleach-based products, which attack grout rather than the tile. Grout can be sealed after curing to simplify cleaning in wet areas. Rated to Class 3 stain resistance and Class B chemical resistance under EN ISO 10545, the surface is safe with ordinary household cleaners and, for exterior installations, pool salts.
