What is Slate?

What is Slate
SIGA Natural Slate

Slate is a fine-grained, layered metamorphic rock that has been formed from a shale-type rock made from clay or volcanic ash.

Slate also contains quartz, feldspar, calcite, pyrite, and hermite. Slate is formed with heat and pressure which causes these minerals to line up parallel to each other and form the layers which allow slate to split into sheets.

Most slate is a deep gray color, but there is also slate available in green, red, brown, black, and purple. Slate flooring can be found in exterior as well as interior spaces because of its strength, beauty, and durability.

Types of Slate Flooring for Kitchen Design

By far, the most common type of kitchen slate flooring is tiles. These have a variety of styles and finishes that you can purchase.

Slate Kitchen Tile Types

There are three main types of tile styles: gauged, ungauged, and calibrated.

  1. Gauged Tiles – Gauged slate tiles are ground down or cut on the bottom side of the tile with the top side remaining textured or uncut to keep its rustic quality.
  2. Ungauged Tiles – Ungauged tiles are left rough and uneven on both sides. These are “tiles” in their most natural state. They remain non-uniform in both size and thickness. These are most often used outdoors.
  3. Calibrated – Calibrated slate tiles are ground down on the top and the bottom to present a more uniform style. These have a smoother appearance which is often used in more modern or contemporary style kitchens.

Slate Kitchen Tile Finishes

Slate tile manufacturers have a variety of tile finishes that you can choose. The most popular finishes are polished, honed, tumbled, and clefted.

  • Polished Slate Tile – Fabricators sand polished slate tiles to create a smooth and tight textured surface. This creates a more slippery surface so this finish does not work well if you have small children who are more accident prone.
  • Honed Slate Tile – Honed slate tiles are also finished to create a smooth surface but not enough to create a shine. These slate tiles have more grip, so they work better in busy areas like kitchens.
  • Tumbled Slate Tile – The surface of tumbled slate tiles have some texture and variation, but the edges and the surface have been softened.
  • Clefted Slate Tile – Clefted slate tiles are the most rough and textured of these four types. It is also called natural slate and is used in rustic and traditional kitchen settings.

Cleaning a Slate Floor and Other Maintenance

In a busy and active room like a kitchen, it is vital to understand how to care for the floor and to keep it clean.

  • Clean Each Day – It is important to keep your slate tiles free from dust and debris that can build up on a slate floor and cause scratching down the road. Each day, sweep or dry-mop the floor.
  • Wet Mopping – Every month or so, or when you have been extra messy with food prep, mop the slate floors with a cleaning solution with a natural pH. Do not use any cleaners with lemon or vinegar. Let them air-dry or use a soft cloth to buff them dry.
  • Sealing a Slate Floor – It is best to maintain a regular schedule for sealing your slate floor tiles for kitchen spaces. Choose a sealer with the type of finish you want from matte to glossy. Clean the slate and allow it and the grout in between the tiles to dry for 24 hours. Pour the sealer into a roller pan. Apply the sealer with a foam roller or sponge. Allow the sealer to dry for 24 hours before you walk on it.
  • Special Cases – If your slate floor scratches, apply mineral spirits which may hide the scratch. Use felt pads on the bottom of furniture to minimize the scratching potential. Clean up spills as they occur to avoid staining. If staining does occur, use a stone poultice to try to remove the stain.
