Black granite

Black granite is a natural stone with a strong presence, high strength and very good resistance in everyday use. It is chosen for projects where the material needs to be beautiful, practical and long-lasting at the same time: for flooring, steps, window sills, terrace and fence copings, as well as custom-made details.

Black granite stone is preferred when a more contrasting, clean and finished appearance is desired. The dark base highlights the architectural lines, combines well with light façades, wood, metal, concrete and natural greenery, while the right finish makes the material suitable for both indoor and outdoor solutions.

In this category, you will find ready-made black granite tiles 60x30 cm with different finishes – polished, leather and flamed surfaces, as well as custom-cut slabs for internal and external window sills, stair treads, terrace copings and fence caps.

What is black granite used for?

Black granite is used for flooring, outdoor and indoor staircases, entrance areas, terraces, façade details, window sills, copings, fence caps and custom-sized stone elements. The reason is that granite is one of the strongest natural stones and performs well under load, moisture, temperature changes and weather conditions.

This makes it a practical choice for areas that are used frequently, such as house entrances, staircases, terraces, courtyards, public areas, internal corridors and transition spaces between interior and exterior.

Ready-made black granite tiles 60x30 cm

Ready-made black granite tiles 60x30 cm are a convenient choice for flooring and cladding when a standard format, easier planning and faster installation are required. The size is practical for both smaller areas and larger projects because it allows an orderly appearance and good joint distribution.

Depending on the application, different surface finishes can be chosen: polished, leather or flamed. This is important because with natural stone, not only the colour but also the finish determines where the material will perform best.

Polished black granite

Polished black granite has a smooth, reflective surface and a deeper visual perception of the colour. It is suitable for indoor flooring, window sills, decorative details, cladding and areas where a smoother and easier-to-clean surface is desired.

For outdoor use, the polished surface should be assessed carefully because it can become more slippery when wet. That is why finishes with better grip are usually preferred for open outdoor flooring and steps.

Black granite leather finish

The leather finish on black granite creates a softer, textured and matt surface. It preserves the depth of the dark stone, but without the strong shine of the polished finish. This makes the material suitable for projects where an interesting, beautiful and tactile feel is desired.

Black granite with a leather finish can be used for countertops, window sills, cladding, indoor steps, decorative details and accents where the surface should feel more lively and closer to the natural character of the stone.

Flamed black granite

Flamed black granite is especially practical for outdoor flooring and steps because its surface is rougher and provides better grip. This is an important factor for entrances, outdoor staircases, terraces, paths and areas that get wet from rain or snow.

The flamed finish makes granite suitable for everyday outdoor use, where safety and durability are more important than strong shine. The stone remains strong, stable and practical even under more intensive use.

Black granite window sills

Custom-cut black granite slabs are suitable for internal and external window sills. They are made according to the specific length, width and thickness of the opening, which allows a more precise solution for houses, apartments, façades and interior projects.

For internal black granite window sills, a polished or leather surface is often chosen. For external window sills, it is important to provide the correct slope, drip groove and suitable finish in order to reduce water retention and staining.

Black granite is a good choice for window sills because it is strong, moisture-resistant and easy to maintain. The dark colour creates a clear finish around the windows and combines well with both light and darker façade solutions.

Black granite stair treads

Black granite is suitable for indoor and outdoor stair treads. For indoor staircases, a polished or leather finish can be used when a smoother surface and a stronger presence of the stone are desired. For outdoor staircases, the more practical choice is a flamed surface because it provides better grip.

Black granite stair treads are a good solution for house entrances, outdoor staircases, terraces, indoor staircases, landings and areas with more frequent use. The material is stable, wear-resistant and suitable for long-term use.

Black granite copings for terraces and fences

Custom-sized black granite slabs can also be used for terrace copings, fence caps, finishing elements on walls and architectural details. These are parts of the project that are often exposed to sun, rain, snow and temperature changes, so the material needs to be resistant and properly finished.

Black granite gives fences, terraces and copings a finished look, while also protecting the structure and creating a clear line. For outdoor applications, it is important to provide slopes, drip grooves and correct installation so that water does not remain on the surface.

What affects the price of black granite?

When searching for “black granite price”, it is important to know that the final cost depends on several factors: type of product, thickness, size, surface finish, quantity, edge processing, drip groove, complexity of the details and transport.

Ready-made 60x30 cm tiles have different prices depending on the finish – polished, leather or flamed. For custom-cut slabs, the price is affected by the exact dimensions, thickness, additional processing, chamfers, rounding, drip groove and application – whether the product is intended for window sills, stair treads, copings or fence caps.

How to choose the right finish?

The choice of finish depends mainly on the place of installation. For outdoor flooring and steps, flamed granite is usually chosen because the surface is rougher and more practical in wet conditions.

For internal window sills, cladding and decorative details, polished black granite can be selected when a smoother and more reflective surface is desired. The leather finish is an intermediate solution – more matt, more textured and with a more natural feel to the touch.

Installation and maintenance of black granite

When installing black granite, it is important to use a stable base, suitable adhesive and correct grouting according to the application. For natural stone, a flexible cement-based adhesive class C2TES1 is usually recommended.

For outdoor flooring, steps, window sills and copings, slopes and drainage should be provided to prevent water retention. This is especially important for steps, terraces, fences and external window sills.

Granite is a resistant material, but proper maintenance helps preserve its good appearance for a long time. Cleaning with specialised products for natural stone is recommended, while aggressive chemicals should be avoided. For outdoor applications, impregnation helps protect against water, stains and dirt.
