Technical Excellence:

Karndean Knight Tile Dove Grey Concrete ST21 features advanced construction technology that delivers authentic polished concrete aesthetics with superior practical performance. The K-Guard+ surface protection combines PU technology to create a hygienic, highly durable finish that resists everyday wear whilst remaining incredibly easy to clean - simply sweep and mop, no sealing or concrete maintenance required. Unlike porous real concrete requiring sealing upon installation and regular resealing to prevent staining, oil penetration, and dust generation, ST21 provides maintenance-free concrete aesthetics. The 0.3mm wear layer provides excellent protection against everyday wear and tear, scratches, and scuffs, making it suitable for residential applications and moderate commercial traffic environments. Beneath the wear layer, a high-definition photographic layer captures every nuance of polished concrete, including the soft dove grey tone, subtle surface texture, gentle tonal variation, and the characteristic appearance of architectural poured concrete. The subtle variation ensures authentic, organic concrete aesthetics rather than flat, artificial appearances. Engineered stability layers are designed to minimize expansion and contraction, ensuring dimensional stability across temperature changes and making the floor compatible with underfloor heating systems up to 27°C - adding warmth to concrete aesthetics. The heavy-duty PVC backing layer provides excellent indentation resistance and recovery, protecting against furniture marks and heavy objects. The 2.0mm total thickness makes Dove Grey Concrete ST21 ideal for both renovation projects where it can be installed over existing hard floors including old concrete, and new build applications where its slim profile doesn't affect door clearances. The non-bevelled edges create seamless tile-to-tile transitions that mimic the appearance of poured concrete floors without visible joints.

Installation & Maintenance:

Karndean Knight Tile Dove Grey Concrete ST21 requires professional glue-down installation, offering creative flexibility that allows you to achieve authentic concrete floor aesthetics with modern installation advantages. The rectangular 305mm x 457mm tiles can be installed in various patterns including straight lay for clean, contemporary grid appearance that mimics concrete panels - the most popular installation for concrete aesthetics creating architectural precision. Offset/brick pattern installation staggers each row by half the tile length for softer, more organic concrete appearance with gentle movement.

For authentic grouted concrete panel effects, add Karndean Design Strips in 3mm or 5mm widths between tiles. DS10 Chalk (shown in product imagery) creates subtle light grey grout that maintains the soft, cohesive concrete aesthetic whilst adding panel definition. DS12 Concrete provides mid-grey grout for slightly more contrast. DS21 White Linen offers pale grout maintaining light tones. DS22 Graphite creates darker grout lines for strong definition and contemporary contrast. Design Strips are particularly effective with concrete tiles, creating the appearance of individual concrete panels with expansion joints or decorative detailing.

Tiles can be cut precisely to fit around fixtures, columns, kitchen islands, and irregular room shapes typical of loft conversions and contemporary spaces. Combine ST21 with other Knight Tile designs for custom installations - use concrete tiles in kitchen zones with wood planks in living areas for industrial-contemporary zoning. The soft dove grey coordinates beautifully with darker Smoked Concrete (ST22) for tonal concrete schemes using different grey depths in different areas.

The gluedown installation means no expansion gaps are required - tiles fit tight against walls, skirting boards, and fixtures for professional, seamless finishes that maximize the flowing concrete effect. Dove Grey Concrete ST21 is fully compatible with underfloor heating systems up to 27°C, adding much-appreciated warmth to concrete aesthetics - transforming cold concrete appearance into warm, comfortable surfaces.

Maintenance is remarkably simple compared to real concrete. The K-Guard+ surface treatment means ST21 requires only regular sweeping and mopping with Karndean Clean to maintain its pristine concrete appearance. Unlike real concrete requiring sealing upon installation, regular resealing to prevent staining and oil penetration, and constant worry about stains, spills, and the dusty surface of unsealed concrete, Dove Grey Concrete ST21 is completely waterproof and stain-resistant from day one. There's no sealing, no special concrete cleaners, no dealing with the porosity issues of real concrete - complete peace of mind. The individual tile format means that should any tile become damaged, it can be replaced without disturbing the surrounding floor. The gluedown format is ideal for renovation projects and can be installed over existing hard floors including old concrete, making it a cost-effective solution for updating industrial spaces or converting properties.
