Q: What makes quartzite different from other natural stones?

A: Quartzite ranks 7 on the Mohs Hardness scale, making it one of the hardest natural stones available. It’s harder than granite, steel, and glass. The stone has extremely low water absorption (under 0.5%), which prevents moisture damage, mold growth, and freeze-thaw cracking. This combination of hardness and moisture resistance creates exceptional durability for both interior and exterior applications.​

Q: Can this stone be used outdoors?

A: Yes, grey quartzite loose stone cladding performs exceptionally well outdoors. The material resists UV fading, withstands freeze-thaw cycles, and handles temperature extremes without damage. It works perfectly for building facades, exterior accent walls, outdoor kitchens, pool surrounds, and landscape features. The natural split face texture adds grip, making it suitable for areas exposed to rain.​

Q: What is the typical thickness of these stones?

A: The stones range from 15-30mm thick (approximately 0.6-1.2 inches). This thickness range allows the stones to fit together naturally while providing adequate strength. The sawn-flat backs ensure consistent adhesion despite the varied face thickness.​

Q: Are the colors consistent across shipments?

A: Natural quartzite features color variations from light silver to deep charcoal grey. Each crate contains a balanced mix of tones. While natural stone always shows some variation, our sorting process ensures consistent color distribution within and between shipments. We inspect all pieces before packing to maintain quality standards.​

Installation Questions

Q: What adhesive should installers use?

A: Professional installations typically use Type S mortar or polymer-modified thinset adhesives. Type S mortar offers excellent bond strength (1,800 psi minimum) and weather resistance for vertical applications. Polymer-modified systems like Laticrete MVIS provide superior freeze-thaw performance and flexibility. Always follow the adhesive manufacturer’s recommendations for mixing and application.​

Q: How difficult is installation compared to stone panels?

A: Loose random stone requires more time and skill than interlocking panels. A 100 sq ft wall takes 1-2 days with loose stone versus 0.5-1 day with panels. The benefit comes from greater design flexibility and a more natural appearance. Contractors familiar with tile work find the learning curve manageable. The random pattern forgives minor spacing variations.​

Q: Do I need special tools for installation?

A: Basic masonry tools work well: notched trowel for adhesive application, level for alignment, diamond-blade angle grinder for cuts, and standard safety equipment (gloves, goggles, dust mask). The sawn backs eliminate need for specialized stone-working tools. Most contractors already own the required equipment.​

Q: Can you install this stone on drywall?

A: Direct installation on standard drywall is not recommended for exterior applications. For interior feature walls, prime the drywall first and use appropriate polymer-modified adhesive. For exterior walls or high-moisture areas, install over cement board, proper weather barrier, and metal lath. This creates a stable substrate that prevents future failures.​

Q: Are corner pieces available?

A: Yes, matching L-shaped corner pieces are available for professional finished edges. These pre-made corners save installation time and eliminate difficult field cuts. Order corners separately based on your project’s linear feet requirements.​

Maintenance and Care

Q: Does this stone need sealing?

A: Sealing is recommended for exterior installations and high-moisture interior areas like backsplashes. A penetrating sealer protects against water infiltration and staining while maintaining the natural appearance. Exterior stones exposed to weather should be resealed every 1-2 years. Interior applications in dry areas can go 3-5 years between sealing.​

Q: How do you clean quartzite stone cladding?

A: Regular cleaning uses pH-neutral stone cleaner or mild dish soap with water. Avoid acidic cleaners (vinegar, lemon juice) and harsh chemicals that can damage the stone. For stubborn dirt, use a soft brush or low-pressure water spray. Never use acid-based cleaners or abrasive pads.​

Q: What maintenance does this material require?

A: Quartzite requires minimal maintenance. Periodic cleaning (2-4 times per year) and occasional resealing keep it looking new. Inspect periodically for any damaged mortar joints and repair promptly to prevent water infiltration. The stone itself won’t chip, peel, or fade, making long-term care simple.​

Ordering and Logistics

Q: What is the minimum order quantity?

A: The minimum order quantity is 1 container (20ft). A standard container holds approximately 225-285m² depending on crate configuration. This MOQ balances shipping efficiency with project needs. For smaller quantities, contact us to discuss consolidated shipping options.​

Q: How long does delivery take?

A: Production takes 10-15 days after order confirmation. Ocean shipping time varies by destination port (typically 2-6 weeks). We provide complete shipment tracking and documentation. Samples ship within 3 days for project approval.​

Q: What payment terms do you accept?

A: We accept Letter of Credit (L/C at sight) and Telegraphic Transfer (T/T). Standard terms are 30% deposit when placing the order, with 70% balance due before shipment. Established B2B customers may qualify for alternative payment arrangements.​

Q: Can you provide material certifications?

A: Yes, each shipment includes complete documentation: CE certification for European markets, test reports for physical properties (flexural strength, water absorption, freeze-thaw resistance), Declaration of Performance, and quality inspection certificates. We maintain all required certifications for international exports.​

Design and Application

Q: What design styles work best with grey stone cladding?

A: Grey quartzite complements multiple design styles. Modern homes benefit from the clean grey palette paired with glass and metal. Traditional designs use the natural texture for rustic charm. The neutral grey tones work equally well in minimalist contemporary spaces and warm transitional interiors. Commercial applications range from corporate office sophistication to casual restaurant ambiance.​

Q: Can you mix this with other stone colors?

A: Yes, many designers combine grey cladding with contrasting stone colors for visual interest. The neutral grey serves as an excellent base that pairs well with warmer rusty tones, cool blues, or earthy beiges. We can provide guidance on color combinations that create balanced, professional results.​

Q: How do you calculate the quantity needed?

A: Measure the wall area in square meters or square feet. Add 10% for cuts, waste, and future repairs. For walls with many openings (windows, doors), measure the full wall area and subtract the opening sizes. Round up to the nearest full crate. Our sales team assists with quantity calculations for complex projects.​
