Mangrove Buff Sandstone is characterized by its unique aesthetic and robust properties, making it a popular choice for architectural and landscaping applications. Quarried in Gosford, Sydney, New South Wales, Australia, this medium-grained, dark beige sandstone is noted for its distinctive light to dark brown wood-textured veining.

Color

• Base Color: Dark Beige
• Veining: Light to Dark Brown with a wood-textured appearance

Physical and Mechanical Properties

• Water Absorption: 5.78% by weight (ASTM C97-83)
• Density: 2230 kg/m³
• Flexural Strength:
• Dry: 8.1 MPa
• Wet: 2.5 MPa
• Compressive Strength:
• Dry: 50.5 MPa
• Wet: 23 MPa
• Hardness: Moderate to High (specific numerical values might not be provided in available data)
• Porosity: Typically high in relation to other stone types due to the sandstone's natural composition
• Slip Resistance: Typically good, suitable for outdoor and high-traffic areas

Chemical and Mineral Compositions

• Quartz: Dominant mineral, providing strength and durability
• Feldspar: Common in sandstone, contributing to the texture and color variations
• Iron Oxides: Present in varying amounts, contributing to the brown veining
• Clay Minerals: Small percentages, influencing porosity and water absorption properties

Usage

• Architectural Applications: Facades, wall cladding, and feature walls
• Landscaping: Paving, walkways, and garden features
• Interior Design: Flooring and decorative elements
• Exterior Applications: Patios, pool surrounds, and outdoor seating areas

Maintenance

• Regular cleaning with mild detergent and water to prevent stain buildup
• Sealing recommended to minimize water absorption and staining, especially in high-traffic or exterior applications
• Periodic resealing depending on usage conditions and exposure

Cutting Sizes (in cm)

• Commonly Available Sizes: 30x30, 30x60, 60x60, 60x90
• Custom sizes available upon request for specific project requirements

Surface Finish Options

• Honed: Smooth, non-reflective finish
• Polished: Shiny, reflective finish, enhancing color and veining
• Sawn: Rougher texture, non-reflective, increases slip resistance
• Sandblasted: For a textured, matte appearance
• Brushed: Soft finish, accentuating natural grain patterns

Mangrove Buff Sandstone's combination of aesthetic versatility and mechanical robustness makes it a suitable choice for a wide range of applications, from subtle interior uses to demanding exterior applications. Regular maintenance and an appropriate finishing choice can enhance its durability and maintain its appearance over time.
