Can New Zealand's Alpine Schist be used exterior applications in very humid climates?
Alpine schist, a type of metamorphic rock found in New Zealand, has been traditionally used for interior applications like countertops, flooring, and wall cladding. However, its effectiveness in exterior applications in very humid climates may be limited.
Alpine schist has good weathering properties but is sensitive to moisture absorption. In an exterior application in a very humid climate, the continuous exposure to moisture, rain, and high humidity levels may lead to moisture absorption by the stone. This can cause the schist to weaken, deteriorate, or develop stains over time.
To ensure successful use of alpine schist in exterior applications in humid climates, several measures can be taken:
1. Sealing: Applying a high-quality stone sealer specifically designed for schist can help reduce moisture absorption and prevent stains. Regular reapplication of the sealer may be necessary in areas with high humidity.
2. Proper installation: Ensuring proper installation techniques, such as creating a moisture barrier and using a professional experienced in working with alpine schist, can help minimize moisture-related issues.
3. Maintenance: Regular cleaning and maintenance, including removing any standing water, preventing the growth of mold or mildew, and addressing any signs of deterioration promptly, can help prolong the life of the exterior application.
4. Climate considerations: If possible, selecting a schist variety that is known for its weather-resistant properties or researching local case studies of successful exterior uses may provide better reassurance.
It is crucial to consult with local experts, architects, or stone suppliers familiar with both alpine schist and the specific climate conditions in question before using it for exterior applications in very humid climates.
