Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. The color of slate is often determined by the amount and type of iron and organic material that are present in the rock.
Slate is popular for a wide variety of uses such as outdoor and indoor flooring, roofing, and flagging because of its durability and attractive appearance.
Prestige Stone & Granite currently offers Mountain Black slate in tiles, steps, and caps. We are working with customers to expand the current color selection.
As a natural stone, slate will maintain its original look for years longer than manufactured options, but it is always important to properly maintain your outdoor space. Use a soft bristle broom consistently to make sure your space is cleared of debris or dirt. When needed, wet the area, and scrub any buildups on the surface of the stones. Besides sealing natural stones, the easiest way to maintain the look of the stone is to prevent settlement on the surface that can cause staining over time.
Avoid applying acidic based cleaners, such as grout or bathroom cleaners, to your slate. Also, stay away from using lemon juice, vinegar, and other multi-purpose cleaning agents. The strong acidic properties of these cleaners are too strong and could end up damaging your stone. Instead, you want to use gentle cleaners and soaps, specifically designed for cleaning natural stone.
If you spill, be sure to clean right away. Do not wipe away the spill, blot it until it disappears and rewash if needed until dry. Do not be afraid to scrub hard on the spot but use a soft bristle brush to avoid damaging the surface.
Ideally you can clean your slate without using a pressure washer. If needed, it is advised to use a light pressure wash for stains caused by leaves or moss.
Yes, it is highly recommended to seal your slate outdoor space. Discuss with your contractor or installer to determine the best sealer for your space. The sealer you select is specific to the features of your space including grout used, hours of direct sunlight and foot traffic.
