California Grey is durable but benefits from proper care:
Seal with impregnating sealer before installation and annually in outdoor/tropical settings.
Clean with mild soap and water; avoid acid-based cleaners.
For pool areas: rinse regularly to prevent salt/mineral buildup.
Request batch-consistent samples and technical support for large-scale installations.
