IDEAL FOR:
Residential Applications: Honed Oyster Slate rigid core flooring excels in every room of your home, with particular advantages for upstairs installations. The 19dB acoustic performance makes it significantly quieter than laminate or engineered alternatives, perfect for upstairs bathrooms where noise reduction to rooms below is essential. The 100% waterproof K-Core® technology makes it ideal for family bathrooms, en-suites, wet rooms, and powder rooms – areas where traditional stone would require professional sealing and maintenance. The DIY-friendly click-lock system means homeowners can tackle bathroom renovations over a weekend without the mess and expense of adhesive installation. Beyond bathrooms, this sophisticated oyster slate design brings spa-like tranquillity to bedrooms, creates coastal elegance in living rooms and dining spaces, and adds timeless style to hallways, entrances, and kitchens. The ability to install over most existing hard floors makes it perfect for renovation projects, while the K-Core® technology's tolerance for minor subfloor imperfections means less preparation work and faster installation. Whether you're creating a Scandinavian-inspired sanctuary, a contemporary coastal retreat, or a classic transitional space, Honed Oyster Slate delivers authentic natural beauty with modern convenience.
Commercial Applications: Knight Tile Rigid Core's combination of affordability, durability, and quick installation makes Honed Oyster Slate an excellent choice for commercial projects where budget, timeline, and performance are all critical. The click-lock floating floor system significantly reduces installation time compared to gluedown alternatives, minimising business disruption and reducing labour costs. The 19dB noise reduction is particularly valuable in multi-level buildings, care homes, assisted living facilities, student accommodation, and community living schemes where acoustic comfort is essential. The 0.3mm commercial-grade wear layer and lifetime residential warranty (10-year commercial) provide the durability needed for moderate-traffic commercial spaces including offices, reception areas, treatment rooms in spas and salons, boutique retail spaces, and hospitality environments. The 100% waterproof construction makes it suitable for commercial bathrooms, changing facilities, and areas where moisture resistance is critical. For traditional housebuilds, rental properties, and budget-conscious commercial projects, Honed Oyster Slate delivers the sophisticated appearance of natural stone with the practical benefits and entry-range pricing that make it commercially viable.
TECHNICAL EXCELLENCE:
Understanding the innovative construction of Knight Tile Rigid Core reveals why it outperforms traditional floating floors:
K-Guard+ Surface Protection: Advanced PU technology creates a hygienic, highly durable finish that resists daily wear, household spills, and scuffing. Unlike natural slate that requires regular sealing and specialized cleaners, K-Guard+ protection means simple sweep-and-mop maintenance keeps your floor looking pristine for years.
0.3mm Wear Layer: The same commercial-grade wear layer used in gluedown Knight Tile provides exceptional durability and longevity. This robust layer ensures the authentic oyster slate appearance remains vivid and beautiful even in high-traffic areas.
High-Definition Photographic Layer: Karndean's sophisticated imaging technology captures every detail of natural oyster slate – the subtle colour variations, the delicate grey veining, the authentic honed texture – creating a remarkably realistic appearance that rivals the real thing.
Click-Lock Mechanism: The proven click-lock system creates secure tile-to-tile connections that lock together firmly yet allow individual tiles to be unclipped and replaced if ever damaged. This flexibility provides long-term peace of mind.
K-Core® Technology: Karndean's proprietary rigid core is the foundation of superior performance. Stronger and more stable than standard SPC or WPC cores, K-Core® technology enables installation over most existing hard floors and tolerates minor subfloor imperfections that would show through with thinner gluedown formats. This means less subfloor preparation, faster installation, and professional results even over slightly uneven surfaces.
Pre-Attached Acoustic Foam Backing: The integrated acoustic foam backing delivers 19dB noise reduction – dramatically quieter than laminate, engineered wood, or standard rigid core products. This makes Knight Tile Rigid Core notably softer and quieter underfoot, creating a more comfortable, premium feel. For upstairs bathrooms and bedrooms, this acoustic performance is invaluable for maintaining peaceful living spaces below.
4.5mm Total Thickness: At more than double the thickness of gluedown Knight Tile (2.0mm), the 4.5mm rigid core construction provides enhanced stability, superior performance over uneven subfloors, and a more substantial, quality feel underfoot.
INSTALLATION & MAINTENANCE:
DIY-Friendly Click-Lock Installation: Knight Tile Rigid Core transforms flooring installation from a professional trade into a manageable DIY project. The click-lock floating floor system requires no adhesive, no messy troweling, no waiting for adhesive to cure, and no sticky cleanup. Simply click tiles together and the floor is immediately ready to use. Homeowners can complete a standard bathroom over a weekend, saving hundreds on professional installation costs.
Floats Over Existing Floors: The rigid core construction means the floor floats over your existing hard surface rather than being permanently adhered. This allows installation over concrete, existing tiles, vinyl, and most other hard surfaces (properly prepared), eliminating the time and expense of floor removal in many renovation scenarios.
Minimal Subfloor Preparation: K-Core® technology's superior stability means it tolerates minor subfloor imperfections that would show through with gluedown formats. While the subfloor should still be clean, dry, and relatively flat, the rigid core construction is far more forgiving than traditional gluedown installation.
Faster Installation: The click-lock system is significantly faster than gluedown installation. No troweling adhesive, no waiting for adhesive to become tacky, no mess to clean up – just click tiles together and move on.
Expansion Gap Required: As with all floating floors, a 10-15mm expansion gap is required around the perimeter and around fixed objects. This gap accommodates the natural expansion and contraction of the floor and is finished with scotia (skirting) for a professional appearance. Karndean offers colour-matched scotia for seamless integration or white paintable scotia for customization.
Compatible With Underfloor Heating: Honed Oyster Slate works beautifully with underfloor heating systems up to 27°C, adding luxurious warmth to bathrooms and living spaces during colder months.
Simple Maintenance: Daily maintenance couldn't be easier – simply sweep or vacuum to remove loose dirt, then damp mop with Karndean Clean for a streak-free shine. The K-Guard+ surface treatment means no sealing, no waxing, no buffing, and no specialized stone cleaners required – a dramatic improvement over natural slate.
Individual Tile Replacement: Should any tile become damaged, the click-lock system allows individual tiles to be unclipped and replaced without disturbing surrounding tiles – a significant advantage over gluedown installation.
Suitable For Most Existing Hard Floors: Install over properly prepared concrete, existing ceramic or porcelain tiles, existing vinyl, and most other hard surfaces. Not suitable for installation over carpet or surfaces with more than 5mm variance per meter.
DESIGN INSPIRATION:
Honed Oyster Slate's sophisticated white-cream palette with delicate grey undertones creates a serene, spa-like atmosphere that works beautifully in contemporary, coastal, and transitional interiors. The authentic honed finish and subtle natural variation bring the timeless elegance of natural slate without the maintenance demands or installation complexity.
Bathroom Sanctuary: Create a luxurious spa-inspired bathroom by pairing Honed Oyster Slate with crisp white sanitaryware, brushed nickel or chrome fixtures, and pale grey or white walls. Add natural textures through woven baskets, linen towels, and organic cotton bath mats to enhance the coastal, serene aesthetic. The 100% waterproof construction and 19dB acoustic backing make it ideal for upstairs bathrooms, while the neutral palette provides a calming foundation that never goes out of style.
Coastal Living Spaces: Extend the serene oyster slate throughout your home to create a cohesive coastal aesthetic. Pair with soft whites, gentle greys, and pale blues in your furnishings and décor. The large-format 305x457mm tiles create clean, contemporary lines with minimal grout lines, while the neutral tone provides the perfect foundation for layering coastal-inspired textiles, natural wood furniture, and organic accessories.
Contemporary Kitchen: Honed Oyster Slate brings sophisticated restraint to contemporary kitchens, pairing beautifully with pale grey or white cabinetry, marble or quartz worktops, and stainless steel appliances. The waterproof construction handles kitchen spills with ease, while the durable 0.3mm wear layer withstands the demands of busy family life. The subtle colour palette allows statement lighting, colourful accessories, or bold backsplashes to take centre stage.
Transitional Elegance: For those who appreciate both traditional and contemporary design, Honed Oyster Slate provides the perfect neutral foundation. The authentic slate appearance honours traditional materials while the clean, contemporary format and pale colour palette keep the look fresh and current. Pair with a mix of traditional and modern furnishings, blend metals and finishes, and layer textures to create spaces that feel both timeless and current.
Scandinavian Minimalism: The pale, neutral tone of Honed Oyster Slate aligns perfectly with Scandinavian design principles. Create light-filled, minimalist spaces by pairing with white walls, pale woods, and simple, functional furniture. The soft colour palette maximizes natural light while the authentic texture adds organic interest without visual clutter.
