Slate is a fine-grained, foliated, and uniform metamorphic rock commonly used in construction and design. It can be crafted into roofing slates, also known as roofing shingles, and is frequently utilized for interior and exterior flooring or wall cladding. Slate tiles are typically installed on mortar and grouted at the edges. To enhance durability, appearance, and stain resistance, as well as to minimize efflorescence and adjust surface smoothness, sealants are often applied.
