Straw Cast Stone is typically used for indoor applications such as wall cladding, decorative panels, and architectural elements. It is not commonly used for outdoor applications due to its potential susceptibility to weathering and moisture damage. Outdoor environments require materials with higher durability and resistance to outdoor elements, including temperature fluctuations, rain, snow, and UV exposure. Therefore, it is not recommended to use Straw Cast Stone outdoors where it will be exposed to these conditions.
