Applications Summary

Stone surfaces extend far beyond kitchen countertops, offering versatile design solutions throughout residential and commercial spaces. Our comprehensive applications guide showcases the many ways to incorporate granite, quartz, and Dekton into your projects.

In kitchens, beyond traditional countertops, consider stone for splashbacks, breakfast bars, and even cabinet facings. The seamless integration of these elements creates a cohesive design while providing durable, easy-to-maintain surfaces. Integrated features like drainage grooves, directing water to the sink, offer both functionality and sophisticated design.

Bathrooms transform with stone applications including vanity tops, shower walls, bathtub surrounds, flooring, and feature walls. Large format stone panels create stunning shower enclosures with minimal seams, while matched shower bases complete the look with elegant continuity. The non-porous nature of quartz and Dekton makes them ideal for wet environments.

Living spaces benefit from stone’s natural beauty and durability in applications like fireplace surrounds, custom furniture, window sills, decorative wall panels, and shelving. Stone fireplace surrounds combine practical heat resistance with timeless elegance, while backlit translucent stone creates dramatic effects for feature walls.

Outdoor applications showcase stone’s weather-resistant qualities, particularly with Dekton’s exceptional resistance to UV exposure, freezing temperatures, and environmental stresses. From exterior cladding and outdoor kitchens to patio tables, these applications extend your living space with surfaces that maintain their beauty despite exposure to the elements.

Commercial environments benefit from stone’s durability and design versatility. Reception desks, conference tables, wall cladding, restaurant surfaces, and retail displays create memorable design statements while providing the durability needed for high-traffic areas.

Each material excels in specific applications. Granite is ideal for areas with heat exposure and where natural variation is desired. Quartz performs exceptionally well in high-use areas requiring minimal maintenance and consistent appearance. Dekton offers superior performance in outdoor applications, flooring, and areas with extreme heat exposure.

Explore our detailed Applications section to discover how stone surfaces can enhance every area of your home or commercial space, with specific guidance on selecting the perfect material for each purpose.

Sustainability Summary

Our commitment to environmental responsibility goes beyond offering durable products. At Hereford Granite, we implement comprehensive sustainability practices throughout our operation, focusing particularly on our state-of-the-art water recycling system and innovative offcut recycling programme.

Each material we offer has different environmental considerations. Granite, as a natural stone, requires no chemical manufacturing process, though energy is consumed during extraction and transportation. Its exceptional durability creates a lifetime product that won’t need replacement for decades, significantly reducing its lifetime environmental impact.

Our engineered quartz surfaces contain over 90% natural quartz crystals combined with resins and pigments. Many collections incorporate recycled materials, including post-industrial waste and recycled glass, reducing landfill waste while creating beautiful surfaces.

Dekton’s production utilizes Sinterized Particle Technology, which mimics the natural process of stone formation. While energy-intensive during production, this creates an ultra-durable material resistant to virtually all forms of degradation, allowing it to replace multiple generations of less durable materials.

Our closed-loop water recycling system demonstrates our commitment to resource conservation. This advanced system captures 100% of water used in our cutting and polishing processes, filtering it through a multi-stage system that removes stone particles down to 1 micron. We recycle over 95% of our process water, saving approximately 10,000 litres daily. The stone slurry collected is pressed into solid cakes used in agricultural applications, creating a zero-waste water treatment process.

Through our sister company, Hereford Stone, we’ve created an innovative solution to the industry-wide challenge of stone offcuts. Every remnant from our fabrication process is carefully catalogued in our inventory system. These pieces range from small offcuts suitable for pastry boards and table tops, to substantial pieces perfect for vanity tops utility room countertops. Through this programme, we’ve achieved a remarkable 74% diversion rate of stone waste from landfill.

FAQ Summary

Our comprehensive FAQ section addresses the most common questions customers have when considering stone surfaces like 12mm Lumena for their homes or commercial spaces. From material differences to installation queries, we’ve compiled expert answers to help you make informed decisions.

Understanding the differences between granite, quartz, and Dekton is crucial for selecting the right material. Granite, a natural stone, features unique patterns and requires periodic sealing. Quartz, an engineered stone, offers consistent colouring and higher stain resistance without sealing requirements. Dekton, created using Sinterized Particle Technology, provides superior resistance to scratches, stains, UV exposure, and heat.

Pricing questions are addressed in detail, explaining how we calculate costs based on square metre measurements, plus additions for edge treatments, cutouts, and installation. We outline what’s included in standard quotes and our payment terms.

The ordering timeline is typically 2-3 weeks from confirmation to installation, including templating, fabrication, and final installation. For natural stone orders, we encourage viewing the specific slab before fabrication to ensure you’re satisfied with the unique characteristics of your selection.

Installation questions cover what to expect on installation day, when you can fully use your kitchen after installation, and how we handle seams and fixtures. We strongly recommend professional installation for all stone surfaces to ensure proper support, sealing, and finishing—protecting both the material and your warranty.

Maintenance and warranty information explains our 10-year manufacturer warranty against defects and 2-year workmanship guarantee. We outline the simple care requirements for each material, with quartz and Dekton requiring only simple cleaning while granite needs periodic sealing.

Technical questions address weight considerations for cabinetry, overhang limitations, undermount sink installation, and edge profile options. These practical details help you plan your project with confidence and understand the possibilities and constraints of working with stone.

For any questions not addressed in our FAQ section or for personalized advice about your specific project, our customer service team is ready to assist you.

Sample Information Summary

Selecting the perfect stone for your project is a significant decision, and our sample programme is designed to help you make the right choice with confidence. We offer multiple sample options to ensure you can properly evaluate materials in your own space before committing to a full purchase.

Our 100mm × 100mm samples provide a representative piece of your chosen engineered stone material, while larger 200mm × 200mm samples offer better pattern visualization for natural stone like granite. We also provide edge profile samples and finish sample sets that showcase different surface treatments like polished, honed, and leathered finishes.

Requesting samples is simple through our website. Browse our product range, select “Request Sample” on materials of interest, and complete the sample request form. Your samples will be dispatched within 2 working days and typically arrive within 2-3 working days for UK mainland addresses.

To properly evaluate your samples, we recommend examining them in your actual installation space under both natural daylight and your artificial lighting at different times of day. This helps you understand how the material will look in varying conditions. Place samples flat and upright to see how light affects appearance, and test compatibility with existing elements like cabinetry, flooring, and fixtures.

It’s important to understand variation expectations when reviewing samples. Natural stone samples represent the general appearance but not the exact pattern you’ll receive, as each slab is unique. Engineered quartz will have more consistent colouring than natural stone, while Dekton offers the highest consistency between samples and final product.

For those seeking a more comprehensive sampling experience, we offer curated sample collections like our Kitchen Countertop Kit featuring our 5 most popular kitchen surfaces, or our Designer Sample Kits that include larger samples in a premium presentation box with additional resources.

To request samples or learn more about our sampling programme, explore our detailed Sample Information section or contact our sample department directly.

Care & Maintenance Summary

Proper care ensures stone surfaces like 12mm Lumena maintain their beauty and functionality for decades. Our care guide provides essential information for keeping granite, quartz, and Dekton in pristine condition with minimal effort.

Daily cleaning is straightforward for all stone surfaces. Simply use a mild dish soap with warm water and a soft cloth. Avoid acidic cleaners (vinegar, lemon), abrasive products, bleach, and ammonia-based cleaners as these can damage your surfaces. For routine cleaning, wipe down with a damp cloth, rinse with clean water, and dry thoroughly to prevent water spots.

Each material has specific care requirements. Granite, being naturally porous, requires periodic sealing (typically annually) but offers unmatched natural beauty. Quartz and Dekton are non-porous and never require sealing, making them exceptionally low-maintenance options.

Prevention is the best approach to maintaining any stone surface. Always use cutting boards rather than cutting directly on the surface, place hot items on trivets or heat-resistant mats, and use coasters under glasses, particularly with colored or acidic beverages. Take care to lift heavy objects rather than sliding them across the surface to prevent scratches.

Despite your best efforts, stains may occasionally occur. Our guide includes targeted solutions for different stain types, from oil-based stains (cooking oil, grease) to organic stains (coffee, tea, wine) and more challenging substances like ink or rust. Most stains can be successfully removed with the right technique.

For granite surfaces, knowing when to reseal is important. A simple water test can help determine timing—place a few drops of water on the surface; if they’re absorbed within 5-10 minutes instead of beading up, it’s time to reseal.

While most maintenance can be handled independently, some situations call for professional assistance. Deep or persistent stains, etching, chips, or cracks may require professional intervention. Our service team offers comprehensive maintenance including deep cleaning, professional sealing, and repairs.

12mm Lumena Installation Guide Summary

When investing in premium stone surfaces, understanding the installation process ensures a smooth experience and exceptional results.

Before installation begins, proper preparation is crucial. Your cabinets should be permanently installed, level, and secure. We recommend clearing the area of belongings and disconnecting plumbing fixtures in advance. Our team will contact you 1–2 days before your scheduled installation to confirm timing and answer any last-minute questions.

The journey begins with templating – a precision measurement process conducted by our specialists. During this visit, which typically occurs 7–10 days before installation, we create exact templates accounting for all angles, curves, and cutouts. This is when you’ll need to finalize important decisions like sink placement, faucet selections, and edge profiles.

On installation day, our expert team delivers your custom-cut stone surfaces and securely places them. Most installations complete in a single day (4-8 hours), though complex projects may require additional time, for larger bespoke projects. Some dust and noise is unavoidable, but our team takes precautions to minimise disruption and protect your home.

After installation, you can begin light use immediately, though we recommend waiting 24 hours before placing heavy items on surfaces or reconnecting plumbing. For granite surfaces, we apply an initial sealing before installation, while quartz, porcelain, Neolith and Dekton require no sealing.

Our quality assurance process includes a final inspection conducted with you present, ensuring your complete satisfaction. Your warranty begins on installation day and is automatically registered with your purchase.

While DIY installation might seem tempting, professional installation offers significant advantages. Stone materials are extremely heavy, difficult to transport, and require specialist tools for proper cutting and fitting. Our professional installation includes a 10-year workmanship guarantee and is essential for maintaining your material warranty.
