Natural stone varies in color, veining, thickness, porosity, mineral content, and finish. The material should be blended before installation, and homeowners should approve the full variation range. Stone-safe mortar, grout, sealer, and cleaner are required. Acid-sensitive stone can etch even when it is properly sealed.
Key considerations
- stain sensitivity
- natural variation
- heat resistance
- unique stone
- decorative mosaics
- multiple finishes
