Hammer Stone Grey Porcelain Paving Slabs 600x600x20 MM

Bring sleek sophistication and versatile style to your outdoor space with premium Hammer Stone Grey Porcelain Paving Slabs (600x600x20mm). Supplied by Paving and Slabs Ltd in full project packs covering 21.6 SQM (60 Slabs Per Pack), this elegant choice combines a contemporary mid-grey color profile with a finely textured, natural stone-effect finish. The balanced 600x600mm square profile delivers a clean, modern grid layout that creates open, cohesive outdoor living zones across patios, terraces, and garden paths.

Manufactured using advanced vitrified porcelain technology, these heavy-duty 20mm calibrated paving flags offer exceptional structural density. The non-porous matrix repels water absorption completely, protecting your patio against winter freeze-thaw cracking, green algae growth, and deep organic staining without requiring periodic sealers or high-maintenance treatment.

Refined Grey Tones Engineered for the UK Climate

Grey paving remains an enduring favorite in modern landscape architecture due to its uncanny ability to complement both contemporary architectural elements and traditional brickwork. Hammer Stone Grey is 100% UV-stabilized, ensuring its refined slate-like tone won't fade under summer sunshine or dull during rain-heavy UK winters. The textured surface subtly masks everyday garden debris and footprints, making it an ideal choice for high-traffic dining spaces, family gardens, and walkways.

Professional Installation Parameters

To guarantee a level, long-lasting installation, Hammer Stone Grey flags must be laid over a compacted MOT Type 1 aggregate base onto a full continuous wet mortar bed (typically a 4:1 sharp sand to cement mix). Never spot-bed porcelain paving; omitting full cement contact beneath the flags creates structural voids vulnerable to cracking under load. Because vitrified stoneware cannot absorb liquids from the cement mix, a high-strength SBR porcelain bonding slurry primer must be painted onto the back of every slab immediately before laying to secure a permanent bond.

Maintain precise 3 to 5mm joint gaps and set up a consistent drainage fall of 1 in 80 away from building walls to manage surface water effectively. Upkeep remains exceptionally simple—organic matter and surface dirt sit loosely on top of the non-porous face, meaning an occasional sweep and wash with warm soapy water or a light pressure washer keeps the finish looking pristine year after year.
