Can Italy's Portoro Macchia Larga Marble be used exterior applications in very dusty climates?
Portoro Macchia Larga Marble is a highly durable and hard marble variety, known for its resistance to weathering and staining. However, when it comes to using it in very dusty climates for exterior applications, there are a few considerations to keep in mind. 1. Dust accumulation: In very dusty climates, such as desert areas, dust can accumulate rapidly on any outdoor surface. While Portoro Macchia Larga Marble is resistant to staining, the dark color may highlight the dust accumulation and require more frequent cleaning compared to lighter-colored stones. 2. Slip resistance: Marble, including Portoro Macchia Larga, is generally a polished and smooth material. In dusty climates, dust particles on the surface of the marble can reduce the overall slip resistance, making it potentially unsafe, especially in areas exposed to water or foot traffic. To mitigate this, the marble can be treated with anti-slip additives or textured finishes. 3. Dust erosion: Excessive exposure to dust and wind-blown particles can affect the surface of the marble over time, causing erosion and dulling of the finish. Regular cleaning and maintenance can help prevent this issue and ensure the marbles longevity. In conclusion, while Portoro Macchia Larga Marble can be used for exterior applications in very dusty climates, it may require more frequent cleaning and maintenance to keep it looking its best. Applying textured finishes or anti-slip additives can help improve its safety in slippery conditions caused by dust accumulation.
