Can Australia's Yetman Sandstone be used exterior applications in very rainy climates?
While the Yetman Sandstone from Australia is known for its weather-resistant properties, using it for exterior applications in very rainy climates may pose some challenges. Here are a few factors to consider:
1. Porosity: Sandstone is generally porous, which means it can absorb water. In very rainy climates, the constant exposure to moisture may lead to increased water absorption. This can result in the stone becoming saturated, potentially causing issues such as efflorescence (white salt deposits on the surface) and freeze-thaw damage.
2. Staining: Rainwater can carry dirt, pollutants, and organic matter that may stain or discolor the sandstone over time. The porosity of the stone might exacerbate this issue.
3. Maintenance: If you decide to use Yetman Sandstone in a rainy climate, regular maintenance would be crucial. Sealing the stone with a suitable water repellent or impregnator will help reduce moisture absorption. However, periodic reapplication of sealant might be necessary to maintain its effectiveness.
4. Design considerations: In wet climates, its important to ensure proper drainage and avoid prolonged exposure to standing water on the stone surface. Incorporating slope and channels to direct water away from the sandstone can help mitigate potential issues.
Ultimately, the appropriateness of Yetman Sandstone for exterior applications in very rainy climates depends on several factors. It is recommended to consult with a local stone supplier, contractor, or architect who can assess the specific conditions and provide tailored advice.
