Technical Specs: BELLASTONE BL5019 'Grey Road' for Contractors

Slab dimensions, thickness and practical weight calculations for contractors

Typical BELLASTONE printed quartz slabs follow industry norms. Contractors should use the following as planning figures and verify exact slab dimensions with the supplier before ordering.

• Nominal slab: 3200 x 1600 mm. This yields good coverage for standard countertops and minimizes seams.
• Thickness: 20 mm (slim islands, countertops with support), 30 mm (standard countertops). Custom thicknesses may be available on request.
• Weight estimates: a 20 mm slab at 2.35 g/cm³ weighs approximately 45–50 kg/m²; a 30 mm slab weighs approximately 67–75 kg/m². Always calculate total weight including countertop overhangs and cabinets when planning delivery and installation.

Printed quartz surface & appearance technology — why printed quartz matters

Printed quartz uses high-definition printing and surface finishing to replicate complex stone veining and microtextures while bonding that decorative layer into a resin-quartz matrix. The result is:

• Consistent pattern repeats and color control — useful for projects requiring repeats across multiple slabs.
• Versatile aesthetics — realistic stone visuals without the unpredictable seams of natural stone.
• Controlled surface texture — light textures (as in Grey Road) provide slip resistance for vertical surfaces and tactile appeal for countertops.

Contractors should request a match set of slabs and a printed sample to confirm alignment and veining behavior before fabrication.

Fabrication and cutting guidelines for contractors (printed quartz)

For safe, high-quality fabrication of BL5019 Grey Road printed quartz, follow these contractor-oriented best practices:

• Cutting and routing: Use diamond tooling designed for engineered stone. Wet cutting is strongly recommended to suppress silica dust and extend blade life.
• Blade selection: Continuous-rim or segmented blades rated for engineered quartz; consult blade manufacturer for feed rates based on blade diameter.
• Polishing: Use resin-bonded diamond pads for finish sequence; start coarse to remove tooling marks and finish with fine pads for a satin or polished sheen depending on the desired finish.
• Edge profiles: Typical edge profiles (bevel, bullnose, eased) are achievable; deep ogee profiles increase risk of chipping and require larger support and extended polishing time.
• Seams: Use color-matched epoxy adhesives; test adhesives on scrap to ensure seam appearance is acceptable for printed patterns.

Always wear appropriate personal protective equipment (PPE) and ensure dust collection systems are in place. See the Health & Safety section below for silica-specific guidance.

Cutting, drilling and sink cut-out practical tips

• Drill pilot holes and use carbides or diamond-tipped bits for fixture holes.
• For undermount sinks, measure and template precisely — printed patterns may require slightly different overhang allowances for visual alignment.
• Clamp slabs with padded supports to avoid edge chipping during machining operations.

Installation best practices and substrate recommendations

Correct installation prevents failures and ensures long service life:

• Substrate: Use rigid, level, well-anchored supports (benchtop cabinets with levelers or cement board where required). Engineered quartz is heavy — cabinetry must be reinforced for island installations.
• Expansion gaps: Provide appropriate expansion joints at vertical terminations and large runs to accommodate thermal movement.
• Adhesives: Use manufacturers' recommended epoxy or polymer adhesives for seams and sink mounting. Do not rely on silicone as the primary seam adhesive for horizontal joints.
• Support spans: For 20 mm slabs, provide full support under countertop runs and avoid excessive cantilevers (>200–300 mm unsupported). For 30 mm, larger cantilevers are possible but still require steel or plywood reinforcement for islands.
• On-site templating: Always template after cabinets are finally installed to account for tolerances and on-site conditions.

Performance: durability, stain and heat resistance of printed quartz

BELLASTONE BL5019 and similar printed quartz products are engineered for long-term durability:

• Scratch resistance: Very good due to high quartz content; avoid sliding cast-iron cookware directly on the surface to minimize abrasion.
• Stain resistance: Excellent when spills are cleaned promptly; most food and beverage stains are removed with mild detergent. Avoid prolonged contact with highly pigmented substances.
• Heat and thermal shock: The resin component limits continuous high-temperature exposure. Use trivets for hot pots; sudden extreme temperature changes (thermal shock) can cause micro-cracking or resin discoloration.

Maintenance & long-term care for contractors advising clients

Providing simple maintenance guidance to your clients reduces callbacks and maintains surface appearance:

• Daily cleaning: Use mild, non-abrasive detergent and a soft cloth or sponge.
• Stain removal: For stubborn spots, a non-abrasive cleaner or a paste of baking soda and water left for a short time can help. Test cleaners on a discreet area first.
• Sealing: Not required — the low porosity of engineered printed quartz eliminates the need for topical sealers.
• Avoid: Strong solvents (acetone, paint strippers), abrasive powders (scouring pads) and direct prolonged heat.

Health & safety: silica dust and workplace controls

Fabrication of engineered quartz generates respirable crystalline silica. Contractors must observe legal and recommended controls to protect workers and clients. Key points:

• Engineering controls: Use wet cutting and local exhaust ventilation (LEV) with HEPA filters to reduce airborne silica.
• PPE: Respirators selected to protect against silica (NIOSH-certified) when airborne levels cannot be adequately controlled; safety glasses, hearing protection, and cut-resistant gloves as appropriate.
• Regulatory guidance: Follow OSHA crystalline silica standards and NIOSH recommendations for exposure limits and work practices. Keep records of training and exposure monitoring where required.

Certifications, testing and warranty considerations

Before specifying BL5019 printed quartz for food-service or institutional projects, request evidence of third-party testing and certifications. Typical certifications to request include:

• Quality management system (ISO 9001) for manufacturing consistency.
• Food-surface safety tests (NSF or equivalent) if surfaces will be used for direct food contact in commercial kitchens.
• Material test reports that document flexural strength, water absorption, and surface wear tests.

Warranty: Many manufacturers offer commercial and residential warranties (commonly 10 years for residential). Confirm warranty scope, exclusions (e.g., misuse, heat damage, improper installation), and required installation practices to keep the warranty valid.
