Surface Treatment of Natural Stones and Its Significance
07.09.2023
Every single stone tells its own millennia-old story and holds a deep-seated beauty within it. This beauty, sometimes invisible at first glance, is just waiting to be revealed through the right treatment. But how can one transform a rugged, untreated stone block into a work of art that stands out in elegance and structure? You'll discover the answer in this article about the surface treatment of natural stones.
The Fascinating World of Natural Stone Surfaces
Natural stone is not merely a material; it is a witness to time, a piece of the earth that has been shaped over millions of years. Within each individual stone lies a unique blend of colors, textures, and stories. But as diverse and impressive as these raw beauties may be, their true magic unfolds through deliberate refinement.
It's more than just an aesthetic enhancement: the surface treatment of natural stones is a fusion of art and science, aesthetics and practice. The right treatment can accentuate a stone's structure, intensify its colors, or imbue it with special qualities that expand its range of applications.
Depending on its intended use—whether as an exquisite kitchen floor, a robust terrace cladding, or an artistic wall element—the stone requires a specific surface quality. This targeted adaptation ensures that the stone not only looks stunning but also fulfills its purpose optimally. Thus, a prehistoric relic becomes a contemporary masterpiece that captivates both in form and function.
Surface Treatment: Polished
Polishing natural stone is an art in itself, requiring both craftsmanship and profound expertise. It's not just about giving the stone a smooth, shiny finish. Polishing, in fact, opens the door to the deep secrets hidden within every stone.
At first glance, it may seem that the primary goal of polishing is a glossy finish. However, the true benefits go far beyond mere appearance. When a stone is polished, its surface is treated in such a way that it reflects light in a special manner. As a result, even the finest details, textures, and patterns that were previously invisible come to the forefront and captivate the viewer's eye.
For example Granite - It's already an impressive stone in its natural form. But after polishing, it transforms into a true masterpiece. The various minerals that make up granite become visible and glisten in the sun, turning every square inch into a visual delight.
Marble , on the other hand, is known for its elegance and timeless charm, gains a whole new dimension through polishing. While it may appear warm and porous in its raw form, polishing gives it a clear, glossy surface. This imparts an exquisite, almost icy character that elevates the luxurious ambiance of a space to a new level.
Surface Treatment: Satin-Finished
In the first phase of satinizing, the stone is ground to eliminate any irregularities and provide it with a uniform yet still rough texture. This is followed by brushing, further refining the previously created surface. This makes it softer and gives it a characteristic texture.
The result of this careful, two-step process is a surface that is graceful, gentle, and yet lightly textured. Its fine texture often reminds one of the delicacy of human skin. Such a finish is particularly remarkable with granite stones, as the satinized surface makes the stone sparkle in a subtle yet impressive manner. This matte shine produced by satinizing adds depth to granite in a way one wouldn't expect.
The satin surface treatment of natural stone has secured a prominent position in the realm of natural stone refinement due to its versatility and distinctiveness. It not only offers an appealing visual aspect but also provides a tactile experience that is unparalleled in its delicacy and elegance. It's as if you're touching the soul of the stone—an experience that captivates both visually and through touch.
Surface Treatment: Honed
Honing is one of the oldest techniques in stone processing. It involves the use of highly advanced diamond stone grinding machines that work on the stone in a very uniform manner. The result is a matte, non-reflective surface that often has an anti-slip effect—ideal for places where safety is a top priority.
Surface Treatment: Flamed
The surface treatment method of flaming involves applying an extremely hot flame to the stone surface, creating a uniform and slightly rough texture. In essence, all hard stones like granite and basalt can be flamed. Often, this technique is used in combination with the processing of brushed natural stones.
Surface Treatment: Brushed
The stone's surface is processed using special brushes with abrasive grains embedded in their bristles. The result is an extremely fine, silky matte surface with a distinctive texture. A brushed stone retains its natural surface structure, unlike the highly smoothing processes of polishing and grinding.
Surface Treatment: High-Pressure Water Jet Technique
A relatively new but popular method for creating slip-resistant surfaces is to process natural stones with a high-pressure water jet, also known as "waterjet-blasted." In this method, the softer components of the stone are washed away more than the harder ones. The result is a rough, slightly hilly, and anti-slip surface texture, particularly suitable for outdoor areas. This process often starts with a previously sawn or ground surface, which is then precisely treated with extremely high water pressure. The resulting surface is similar to one that has been flamed and brushed.
The main advantage of the water jet technique compared to the flamed and brushed surface lies in the fact that flaming mainly removes the hard minerals from the surface, whereas the water jet technique washes away the softer components more significantly. As a result, the surface produced is more durable and highly recommended for heavily trafficked areas.
Conclusion: Surface Treatment of Natural Stone for Altered Character
The surface treatment of natural stone is an essential step in unlocking the full potential of the stone. Whether polished, honed, ground, or treated with a high-pressure water jet—each method has its own merits and suits different applications and style preferences. Depending on the surface treatment, the same stone takes on a unique character. However, all treatment methods share a common trait: they transform raw stone into a unique work of art.
