Natural stone is uniquely created by nature millions of years ago. Individual colours and structures make each stone unique, creating special emotions and an extraordinary atmosphere. Durable, easy to care for, natural and timelessly beautiful. Its architectural versatility and highest functionality, together with an exceptional look from simple elegance to earthy cosiness, make natural stone an exciting building material for outdoor areas: Mediterranean floor panels, a rustic pavement, special places in nature design, a swimming pool with noble pool surround, troughs placed in the green and design elements made of natural stone, perfectly shaped frames of beds. This makes the personal space feel like an oasis, a place for peace and special experiences, for recharging your batteries and cosy get-togethers. The unique place to enjoy life.
Even structure and yet rough surface – that’s what represents the flamed surface. At flaming, great heat is applied to natural stones. The high roughness is created by dissolving particles, which are close to the surface on the stone. The handling is either done automatically or with handheld tools, but the process is not easily automated and because of that it is also applicable for uneven stones. Typical application possibilities are floorings outside.
The surface handling of the brushed surface is done by brushing the natural stone, as its name says. That happens after the flaming or sandblasting of the natural stone. The surface is being roughened at the pre-treatment, then through brushing it appears still rough but much softer.
The handling of honed surfaces varies a lot. The level of the grinding operation is indicated with the terms C30 to C800 whereat C800 indicates that the surface is almost polished and C30 represents very rough ground joint where brush- or saw marks can be visible. The advantage of the honed surface is that it can be reworked at any time (even if it is already built-in). Because the handling can be done manual or automatic both even and uneven surfaces can be grinded.
As its name says, the stones are being polished with this surface handling, whereby it gets a bright and shiny visual appearance. The colours and structure of the natural stone are visible. Due to the polishing of the surface the material also gets smooth and a little bit slippery. The polished surface is perfect for interior areas because of the least liability for stain and the reflection of the light. Also, fluids infiltrate less in the stone.
The handling of the bush-hammered surface is being done by a bush hammer, a tool with pyramidal teeth. The stones surface is mechanically roughened whereby the natural stones seems to be “dotted” with small dents in the surface. The handling is either done automatically or with handheld tools. This causes spalling in the stone, making the surface rougher. The bush-hammered surface can perfectly be used in outside area because of the high requirements for the anti-slip property. It must be pointed out that this surface handling differs only slightly from the sandblasted surface. Bush-hammered surfaces are great for uneven items. Because of its high roughness and therefore the high liability for stains, the pointed surface is not ideal for indoor areas.
Rough-hewn surfaces are being handled with sharp chisels. For that dents are being made in the surface whereby a rough and uneven surface occurs. It can be used perfectly for even and uneven surfaces because the handling happens manually. Rough-hewn surfaces are only suitable for decorative applications.
For tumbled surface handlings natural stone tiles are placed with quartz and water in a rotating gravity mixer. By pushing against each other edges are cut off and surfaces are roughened. After the handling the tiles look antique with rounded edges, which are mostly used for floorings.
For sandblasted surfaces different jet pressure and grit is applied to the natural stone. Because of that roughened surfaces develop, which are slip resistant and easy to clean. Sandblasted surfaces comply with the highest requirements for anti-slip property, same as the bush-hammered surface, which makes it the perfect surface for outdoor areas. Additionally, this surface is the most economically producible surface for outdoor areas.
The mechanical splitting of this surface handling creates uneven and natural surfaces on natural stones. This can be a benefit because natural stones can be used in their original form. The surface develops due to separation of the raw materials by force, whereby the typical cleavage face occurs (for example cobblestones). The split-faced surface is ideal for floorings, façade covers or natural stone bricking.
The silky-matt surface of this handling is done by two steps: first the natural stone is honed and then brushed. This progress creates a dull appearance, the stone does not shine and looks like leather. Leather-finished surface handling is also called satin-finished or simply leather-looking. Natural stones with this handling can be used in many ways, both indoors and outdoors, and are particularly easy to care for.
The surface handling “waterdropped” is a special eye-catcher because the natural stone is processed in a way that the surface looks like it is wet and filled with water droplets. The waterdroppd-surface receives this three-dimensional character through several processing steps and is mainly used for natural stones with a rough surface.
