Can Iran's Hamadan Black Granite be used exterior applications in very rainy climates?
Irans Hamadan Black Granite is known for its durability and resistance to weathering, making it suitable for exterior applications. However, using any natural stone in very rainy climates can pose some challenges. Here are some points to consider when using Hamadan Black Granite in such conditions:
1. Porosity: Even though Hamadan Black Granite is known for having a low porosity, it may still absorb some moisture. In very rainy climates, the excessive moisture might penetrate the stone, potentially causing staining or damage over time.
2. Sealing: To enhance the granites resistance to moisture, it is recommended to seal the stone properly. A high-quality penetrating sealer can help reduce its porosity and protect it from water damage.
3. Maintenance: Regular maintenance, including routine cleaning and resealing, is essential to keep the granite in good condition. This is particularly important in rainy climates, as the stone may be exposed to more moisture and be prone to the growth of moss, algae, or mildew.
4. Slope and drainage: Proper installation with the correct sloping and drainage system is crucial to ensure the water runs off the surface and doesnt accumulate around the granite. Standing water can potentially cause problems over time.
5. Frost resistance: If the climate is not only rainy but also experiences freezing temperatures, the granites frost resistance should be considered. Hamadan Black Granite is generally known to have good resistance to freeze-thaw cycles but understanding the local climate and the stones specific characteristics is important.
In summary, Irans Hamadan Black Granite can be used in exterior applications in very rainy climates. However, extra care should be taken to properly seal, maintain, and ensure adequate drainage to mitigate the potential risks associated with excessive moisture.
