Can Turkey's Antique Onyx be used exterior applications in cold climates?
While onyx is a versatile and durable material, using Turkeys antique onyx in exterior applications in cold climates requires careful consideration. Onyx is a sedimentary rock composed mainly of calcite or aragonite minerals, which are softer and more porous than other stones like granite or marble.
In cold climates, the exterior application of onyx might be challenging due to several factors:
1. Freeze-thaw cycles: In cold climates, freezing and thawing cycles can cause water to seep into the stones pores. When the water freezes and expands, it can lead to cracking or deterioration of the onyx.
2. Moisture absorption: Onyx is more porous compared to other stones, making it susceptible to moisture absorption. In cold climates where snow, ice, or high humidity is present, the onyx could absorb water, potentially causing damage.
3. Staining: Onyx is vulnerable to staining and discoloration from environmental factors. In cold climates, the presence of de-icing salts or harsh chemicals used for snow removal can increase the risk of staining and damage to the onyx surface.
To successfully use Turkeys antique onyx in exterior applications in cold climates, some precautions can be taken:
1. Sealing: Proper sealing is crucial to protect the onyx from moisture absorption. Regularly seal the onyx with a high-quality penetrating sealant to reduce the risk of water infiltration.
2. Maintenance: Regular maintenance, including cleaning and removing any snow or ice buildup, is essential to prevent moisture-related problems. Avoid using harsh chemicals during the cleaning process to prevent the onyx from being damaged or stained.
3. Thermal insulation: Consider adding thermal insulation to the exterior application to protect the onyx from extreme temperature variations and potential freeze-thaw damage.
Before using Turkeys antique onyx in exterior applications, it is advisable to consult with a professional stone supplier or installer experienced in working with onyx. They can provide specific guidance based on the climate conditions and the specific characteristics of the onyx being used.
