Natural stone has high texture and delicate texture, which is very popular as decorative material for interior and exterior decoration of buildings.
In addition to the natural texture can bring people unique natural art visual effects, but also through a variety of surface processing methods, to create a variety of visual experiences. Such a rich variety is also one of the charms of stone. By doing “superficial”, stone can not only more fully show their charm, but also have the opportunity to improve their visual defects, enhance the value in the eyes of consumers.
Stone surface treatment
Stone surface treatment refers to the use of different processing methods to ensure the safety of stone, to show different material styles, to meet various design requirements. Taking marble as an example, its surface treatment is very important, because designers will choose the appropriate surface treatment form according to the type and pattern of stone, the degree of hardness, and the characteristics, and then present it in the interior space, to better ensure the effectiveness of the design works, and meet the design needs of safety, functionality, and aesthetics, It can also avoid some design problems.
There are many forms of surface treatment for marble, and different surface treatment methods can be extended from the aspects of anti-skid, anti-fouling, easy cleaning, and anti-collision. So, what are the common stone surface processing methods in the industry? According to the actual use, it can be roughly divided into the following four categories:
● Conventional surface treatment, such as polished surface, matte surface, etc;
● Antiskid surface treatment, such as acid wash, fire, cloth, water spray, litchi, pineapple, etc;
● Decorative surface treatment, such as antique surface, groove surface, mushroom surface, natural surface, sandblasting surface, acid pickling antique surface, etc;
● Engraving board and special surface treatment as long as you can think of the surface texture can be achieved, such as crocodile skin carving, water carving, and so on.
Now let’s introduce them one by one
Conventional surface treatment
1. Polished Surface
A polishing surface is a kind of surface that is made by rough grinding, fine grinding, and fine grinding, polishing powder, and polishing agent. The surface is as bright as a mirror, with bright colors, few and small pores. General stone luminosity can achieve 80, 90 degrees, which is characterized by high luminosity, a strong reflection of light, often can fully display the rich and colorful color and natural texture of stone itself.

2. Matte Surface
Matte surface refers to the smooth surface, less polishing treatment with resin abrasive on the surface. Its luminosity is lower than the polished surface, generally about 30-60. After sub-light treatment of a stone, often has a certain luminosity, but the reflection of light is weak, is a smooth surface, but the luminosity is low.

Antiskid surface treatment
1. Acid Wash Face
Acid washing surface is to uses a strong acid to corrode the surface of the stone to achieve a visual effect. After treatment, the surface of the stone will have smaller corrosion traces, which is more rustic than the polished surface, and strong acid will not affect the interior of the stone. This process is commonly used in marble and limestone, with good anti-skid performance. It is often used in toilets, kitchens, roads, and also used to soften the luster of granite.

2. Noodles On Fire
Fire surface refers to the rough surface of stone surface processed with acetylene, oxygen as fuel, propane, oxygen as fuel, or liquefied petroleum gas and oxygen as fuel. Due to the effect of fire, some impurities and low melting point components on the stone surface can be burned, thus forming a rough finish on the surface, so there will be a certain prickle feeling on the hand.
There are certain requirements for the thickness of marble in the processing of fire surfaces. Generally, the thickness of stone should be at least 20 mm and there should be crystal on the surface to prevent the stone from cracking during the processing.

3. Cloth Leather Surface
The stone leather surface is carefully polished from coarse mesh to fine mesh by grinding brush. After the production, the surface presents an uneven Satin matte effect and then is polished to achieve an uneven Satin high gloss effect.

4. Wash Your Face With Water
The stone surface processed and washed by the water knife machine is uneven, but the surface is smooth without edges and corners, which is similar to acid washing surface, but the surface color is close to smooth surface, slightly deeper than acid washing surface, and the water absorption is small.

5. Litchi Noodles
The Litchi surface is made by hammering on the surface of granite with a hammer-shaped like a litchi peel. After treatment, the surface of the stone will form a rough surface shaped like litchi peel, which is uneven. This kind of processing method can be divided into machine-made (machine-made) and hand-made (hand-made). Generally speaking, hand-made is finer than machine-made, but it is more laborious and the price is relatively higher.

6. Pineapple Noodles
Pineapple noodle is to make the stone surface more rugged and grainy than litchi noodles. The texture of the material is just opposite to that of the washed surface, with a weak concave-convex feeling and large grain feeling.

Decorative surface treatment
1. Antique Face
The antique surface is to eliminates the characteristics of hand pricking on the surface of the fire surface. After the stone is burned first, it is then brushed 3-6 times with a steel brush. The antique surface has the concave and convex feeling of a burning surface and is smooth to the touch, so it is a very good surface treatment method.

2. Grooving Surface
The grooved surface is also called “groove” or “wire drawing”. It is a groove with a certain depth and width on the stone surface. It is usually a straight groove with a two-way groove (5mm) × 5mm) and unidirectional groove; If required, a water knife can also be used to pull curve notch, but its material cost is higher. To avoid accidental injury, the passivation treatment of notch should be considered, and polishing can be done when necessary.

3. Mushroom Noodles
Mushroom surface refers to the surface of the stone with chisel and hammer percussion forming like an undulating mountain-shaped plate. The thickness of conventional stone cannot be treated with this surface. Generally, the bottom should be at least 3cm thick, and the convex part can be more than 2cm according to the actual requirements. This kind of processing method is commonly used in economic enclosures.

4. Natural Surface
The natural surface, commonly known as natural fracture surface and cracking surface, is a kind of stone material that is mechanically separated from the middle without any treatment. The surface of this kind of stone material is very rough and extremely uneven, which is especially tensile under the illumination of light. Natural marble should also consider the relationship between stone weight, thickness, specifications, and installation technology, which is suitable for the natural style and rough style space.

5. Sandblasting Surface
Sandblasting of natural stone (stone sandblasting surface) is a kind of stone surface processing method which is similar to glass abrasive effect by using angular emery, quartz sand, river sand, and other abrasives to impact the stone surface driven by compressed air (or water). Now the process is generally realized by a stone sandblasting machine, and the airflow can be adjusted according to the stone hardness to achieve the required depth and uniformity.
This processing method can make the stone have a good anti-skid function, but also beautiful, so the application range is very wide, not only can be used for the processing of thin plate, specification plate, and other natural stone products, but also can be used for the processing of special-shaped stone such as lines, columns, railings, steps and corners, and sandblasting is also widely used in stone carving, In hotels, conference rooms, museums, corridors, and other occasions can often see

Engraving board and special surface treatment
As long as you can think of the surface texture, can be achieved in the form of a carving plate, marble carving plate and special surface treatment of decorative effect are very beautiful, excellent.
The plasticity of stone is very strong, so with the update of production equipment and the continuous improvement of technology, I believe there will be more amazing processing surfaces for you. If you have a better way of stone surface treatment. You are welcome to email me at sales@sntstone.com.
