Rosal Original Limestone

Rosal Original Limestone is a high-quality limestone quarried in Codaçal, Porto de Mós, Portugal. Known for its uniform fine to medium-grained texture and compact crystalline structure, this limestone is both visually appealing and functionally robust. Its soft and refined appearance comes from its very light, gentle beige tone with subtle color variations. The stone has minimal veining, adding to its elegance and uniformity.

Physical and Mechanical Properties:

• Water Absorption: 3.20%
• Density: 2440 Kg/m³
• Flexural Strength: 14.1 MPa
• Compressive Strength: 70.0 MPa
• Hardness: Typically, limestone rates between 3 and 4 on the Mohs scale, in line with similar high-quality limestones.
• Porosity: Moderate, contributes to water absorption and breathability.
• Slip Resistance: Generally moderate, given its surface characteristics; specific slip resistance values depend on finish.

Chemical and Mineral Composition (% by weight):

• Calcium Carbonate (CaCO3): Predominantly calciclastic and micritic in nature.
• Micrite: Indicates fine-grained carbonate cement.
• Sparite: Rare occurrences, contributing to minor textural variations.
• Silicates/Other Minerals: Trace elements may include clay minerals or quartz, depending on quarry section.

Usage:

Exterior and Interior Applications:

• Cladding
• Flooring
• Wall coverings
• Architectural elements like columns, balustrades, and moldings

Decorative Elements:

• Fireplaces
• Countertops
• Vanity tops

Maintenance:

• Cleaning: Use mild detergents; avoid acidic or harsh chemical cleaners to preserve the stone's surface.
• Sealing: Periodic sealing is recommended to enhance stain resistance and preserve appearance, especially in high-traffic or wet areas.
• Inspection and Repair: Regularly check for chips or cracks and address them promptly to maintain structural integrity.

Common Surface Finish Options:

• Polished: Offers a glossy, reflective surface, ideal for interiors where elegance is paramount.
• Honed: Provides a smooth, matte finish, balancing slip resistance with aesthetic appeal.
• Brushed/Antiqued: Adds texture for a rustic feel, enhancing slip resistance.
• Sandblasted: Creates a rougher texture for more grip, suitable for exterior paving.

Rosal Original Limestone, with its elegant uniformity and fine texture, is a versatile material suitable for a range of design applications, offering timeless beauty while being straightforward to maintain.
