Caring for thin stone is very simple. Since thin stone is completely natural, it's tough and will not peel or chip in most climates. No treatments are required because the colors will not fade or change in the sun. The only recommended steps are periodic inspection and cleaning. During inspection, look for rare cracks or signs of damage, much like what you would do to your windows or existing siding. Cleaning this stone can be done with a low setting on a power washer or by brush while you clean the windows. Minor dirt can even be hosed off while you water the flowers. It is imperative to not use any type of acid especially muriatic.
