Suitable for interior and exterior use. From very lightly Riven Brazilian Slate for a more contemporary feel, through to very Rustic Riven Slate to create the old farmhouse flag stone effect. Available in most sizes from 300 x 300 mm up to 900 x 900 mm. After being sliced into tiles slate is still naturally going to be bumpy and broken. In many cases this is desirable as it makes the material feel rough and earthy. When the surface is left Un-Refined it is called Cleft. Although the term Natural Stone is also often used to refer to it looking more like it would in it’s untouched state. Cleft Slate has great traction even when wet, but if the ridges are too extreme it can be uncomfortable to walk on with bare feet. In some cases Slate tiles will be polished to the point where they have perfectly smooth surfaces. This process dulls both the dimensionality and the colors in the stone, though the material does retain the same basic hues. When you touch the face of a honed piece of slate, you will feel that it still has some traction, though less than Cleft floors will. Another effect of honing is that tiles will be more likely to show stains and dirt and will be easier to scratch.
