Slate needs to be properly cleaned and sealed after installation and periodically cleaned and sealed thereafter. Any aggressive cleaning may only make matters worse. Professional services can help maintain your slate.
CLEAN: We completely strip your slate, removing heavy waxes, floor finishes, and soap residue that trap dirt, grime, and other contaminants. Then we clean and sanitize your slate in preparation for the finish you want.
REFINISHING: There are several different ways to finish slate, including slate color enhancers, topical coatings such as wax, penetrating sealers, and more. The finished look we can achieve depends on your preference — a gloss finish, matte finish, or a low luster finish.
