Maintaining and cleaning a slate floor or counter is relatively easy as long as you keep it in good condition.
Slate is comprised of very fine granular metamorphic rock which forms naturally in layers and gives it its rich texture and interesting colors.
Due to its porous nature slate can stain if not maintained. To maintain slat a commercial sealer needs to be applied during installation and this sealant needs to be stripped away periodically then reapplied to keep the product looking great and permanently sealed.
Finally, plan on establishing some “House Rules” like, not wearing shoes, having small rugs around the stove, counter eating area and refrigerator to catch splatters and spills before they hit the floor. Use ¼ cup of white vinegar to a gallon of warm water to spot remove stains. Then clean the entire floor with plain warm water from a tightly wrung rage for weekly cleaning.
