Each stone needs a good planned maintenance schedule in place, to preserve and to delay restoration as long
as possible. Daily maintenance will consist of dry and damp mopping, this should be done with a good stone

If the slate is honed or polished regular maintenance will be required to maintain their appearance and
remove any scratches or loss of gloss and shine.
Slate is a versatile stone that can be rough, polished, smooth or polished to a shine. Slate tiles can look very
natural, but many of our customers complain about their boring colors, “garden path” look. In this situation,
the slate is treated with a sealant that will serve to deepen the color without sacrificing the rough, layered
structure of the stone.
