Black Slate Split Face Cladding Tiles 350x180 From £32.99/m2

Black Slate Split Face Cladding Tiles 350 x 180 are a versatile natural stone wall covering for interior and exterior applications. Their deep charcoal, graphite and natural black tones create a clean, understated appearance that works particularly well on feature walls, fireplaces, garden walls, entrance walls and contemporary commercial interiors.

The 350 x 180 mm format is formed from individual natural slate pieces in different lengths, widths and approximately 10–20 mm thicknesses. The varied stone sizes and staggered surface levels create a pronounced 3D split face texture, with some pieces projecting further forward while others sit slightly deeper. This produces natural shadow, depth and variation across the finished wall.

For exterior applications, Black Slate is particularly suitable for garden walls, courtyard walls, entrance features and other decorative wall areas. Its dark neutral colouring provides a strong contrast against lighter paving, rendered walls, timber, planting and architectural metalwork, while the naturally cleft surface retains the authentic appearance of real stone.

Indoors, Black Slate Split Face Cladding Tiles can be used for fireplace surrounds, living room feature walls, reception areas, restaurants, bars, hotels, offices and retail interiors. The charcoal-black colouring and layered stone texture provide a strong architectural finish without relying on artificial patterns or printed surfaces.

Black Slate is a natural stone product, so individual pieces can vary in charcoal and black tone, natural cleavage, mineral markings, thickness and surface texture. These variations are part of the natural character of slate and contribute to the depth and individuality of the finished wall.

Can Split Face Tiles Be Used Outdoors?

Yes, many natural stone split face tiles are suitable for indoor and outdoor wall applications when installed correctly. For exterior use, the wall must be strong, stable and properly prepared, with a suitable exterior-grade flexible adhesive. The top and exposed edges should also be detailed to prevent water from penetrating behind the tiles, particularly in UK rain and frost conditions.

Where Can Split Face Tiles Be Used?

Split face tiles can be used in both outdoor and indoor applications. Externally, they are commonly installed on garden walls, exterior feature walls, façades and entrance areas where the substrate and wall construction are suitable.

Internally, they are suitable for living-room feature walls, hallways, kitchens, fireplace surrounds and selected bathroom feature walls. They are not normally recommended inside enclosed shower areas or other locations exposed to constant direct water because their uneven surface and close-jointed construction make waterproofing and cleaning more difficult.

Do Split Face Tiles Need Sealing?

For exterior split face tile installations, sealing is generally recommended. Outdoor natural stone is exposed to rain, frost, dirt, algae and regular weather changes, so a breathable natural stone sealer can help reduce water absorption and make the surface easier to maintain.

For interior use, sealing depends on the location. It is recommended in kitchens, bathroom feature areas, fireplace surrounds and other places exposed to moisture, staining or soot. In living rooms, bedrooms, hallways and other dry interior spaces, sealing is usually optional rather than essential.

Always test the sealer on a small area first. Choose a breathable natural stone sealer that maintains the natural appearance of the stone rather than leaving a dark, glossy or coated finish.

What Surface Should Split Face Tiles Be Installed On?

Split face tiles should be installed on a strong, stable, clean and suitable substrate capable of supporting the weight of natural stone. Common suitable surfaces include concrete, brickwork, blockwork, sound cement render and suitable cement-based tile backer boards. Weak plaster, loose render, painted surfaces and unsupported standard plasterboard should not be tiled directly without appropriate preparation or reinforcement.
