What are the differences between using schist vs. slate for outdoor sofa backs?

When choosing natural stone for outdoor sofa backs, schist and slate are two popular options, each with distinct characteristics. Schist, a metamorphic rock with a flaky texture, offers a unique, rustic appearance due to its layered mineral composition. It is durable but may require sealing to withstand harsh weather. Slate, on the other hand, is denser and more uniform, providing a sleek, modern look. Its natural water resistance makes it low-maintenance for outdoor use.

In terms of durability, slate generally outperforms schist in wet climates, as it is less prone to splitting. However, schist’s varied color and texture can add visual interest to outdoor furniture. Maintenance-wise, slate requires minimal upkeep, while schist may need periodic sealing to prevent weathering.

Ultimately, the choice depends on aesthetic preference and climate conditions. Slate suits contemporary designs and rainy environments, while schist excels in rustic settings with moderate weather. Both stones elevate outdoor furniture with natural elegance.
