What is stone surface treatment?

In addition to the natural texture of the stone, which can bring people a unique natural artistic visual effect, it can also create a kaleidoscopic visual experience through a variety of surface processing methods. Such rich changes are also one of the charms of stone.

By doing "surface articles", stone can not only show its own charm more fully, but also have the opportunity to improve its own visual defects and enhance its value in the eyes of consumers.So, what are the more common stone surface processing methods in the industry?


What is stone surface treatment

Stone surface treatment refers to the use of different processing treatments on the surface of the stone under the condition of ensuring the safety of the stone itself, so that it presents different material styles, so as 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 the stone, the degree of hardness and characteristics, etc., and then present it in the indoor space.

There are many forms of surface treatment for marble. From the perspective of non-slip, stain-resistant, easy-to-clean, and anti-collision, different surface treatment methods can be extended. Next, let's take a look at what surface treatment methods are available for stone.


Conventional surface treatment

Polished surface: Polished surface refers to the veneer made by rough grinding, fine grinding, and fine grinding of a flat plate with abrasives, and polishing with polishing powder and agent. The surface is as bright as a mirror, brightly colored, with few and small pores.

Generally, the luminosity of stone can be 80 or 90 degrees, and it is characterized by high luminosity and strong reflection of light, which can often fully display the rich and gorgeous color and natural texture of the stone itself.


Matte surface: Matte surface means that the surface is flat, and the surface is less polished with resin abrasives. Its luminosity is lower than that of the polished surface, generally around 30-60.

Stones that have undergone matt treatment tend to have a certain degree of luminosity, but the reflection of light is weak. It is a flat and smooth surface, but with low luminosity.


Non-slip surface treatment

Pickled surface: The pickled surface achieves the visual effect by corroding the surface of the stone with strong acid. After the stone has been treated, there will be smaller corrosion marks on the surface.It looks more rustic than the polished surface, and the strong acid will not affect the interior of the stone.

This process is commonly used in marble and limestone, and has good anti-slip performance. It is mostly used in toilets, kitchens, and roads, and it is often used to soften the luster of granite.


Burning surface: Burning surface refers to the rough surface finish processed by using acetylene and oxygen as fuel or propane and oxygen as fuel, or using high temperature flame produced by liquefied petroleum gas and oxygen as fuel.

Due to the effect of fire, some impurities and low melting point components on the surface of the stone can be burnt, thereby forming a rough finish on the surface, so there will be a certain tingling sensation on the hand.

The processing of the fire surface has certain requirements on the thickness of the marble. Generally, the thickness of the stone is at least 20mm and the surface is crystallized to prevent the stone from cracking during the processing.


Textured surface: The method of textured surface is to process the surface of the stone into a textured texture, which can retain the texture of the stone and imitate the texture of the wallpaper, giving a feeling of wall covering.


Washed surface: The surface of the stone is washed with a waterjet machine, showing unevenness, but the surface is smooth and has no edges and corners, which is similar to the pickled surface, but the surface color is close to the smooth surface, slightly darker than the pickled surface, and the water absorption rate is small.


Lychee surface: Lychee surface is made by hitting the granite surface with a hammer shaped like lychee skin. After treatment, the surface of the stone will form a rough surface shaped like lychee skin, with unevenness.

This processing method can be divided into two types: machined surface (machine) and hand-laid surface (manual). Generally speaking, hand-laid surface are more dense than machined surface, but they are more laborious and the price is relatively higher.


Pineapple surface: The method of pineapple surface is to process the stone surface more unevenly than the litchi surface, and the graininess is more obvious. The texture of the material is just the opposite of that of the water-washed surface, with weaker unevenness and large graininess.


Decorative surface treatment

Antique surface: The antique surface is to eliminate the thorny characteristics of the surface of the fire surface. After the stone is first burned with fire, brush it with a steel brush 3-6 times, that is, the antique surface.

The antique surface has the unevenness of the burnt surface, and it is smooth to the touch and will not pierce your hands. It is a very good surface treatment method. The processing of antique noodles is time-consuming and expensive.


Grooving surface: Grooving surface is also called "grooving" or "drawing", which is a groove with a certain depth and width on the surface of the stone.Usually it is a straight slot, which can be divided into two-way slot (5mm×5mm) and one-way slot; if required, a water jet can also be used to draw a curved slot, but the material cost is higher.

In order to avoid accidental injury, the passivation of the notch should be considered when adopting this method, and it can be polished if necessary. Recently popular format elements can be used to process stone in this way.


Mushroom surface: Mushroom surface is shaped like ups and downs on the stone surface with a chisel and hammer.

This processing method has certain requirements for the thickness of the stone, generally the bottom must be at least 3 cm thick, and the raised part can be more than 2 cm according to actual requirements. This processing method is commonly found in economical enclosures.


Natural surface: The natural surface is commonly known as the natural fracture surface or the crack surface. It is a piece of stone that is naturally split from the middle by a machine without any treatment after splitting. The surface of this stone is extremely rough and extremely uneven. When illuminated by light, it seems particularly tense.

Natural surface marble should also consider the relationship between the weight, thickness, specifications and installation process of the stone, which is suitable for natural style and rough style space.


Sandblasting surface: The sandblasting treatment of natural stone (stone sandblasting surface) is to use angular emery, quartz sand, river sand and other abrasives to impact the stone surface under the drive of compressed air (or water).The obtained stone surface processing method is similar to the glass frosting effect.

At present, the process is generally realized by a stone sandblasting machine, which can adjust the airflow size according to the hardness of the stone to achieve the required depth and uniformity.

This processing method can make the stone have a good anti-slip function without losing its beauty, so it has a very wide range of applications, not only for the processing of natural stone slabs such as thin plates and specification plates.

At the same time, it can also process special-shaped stones such as lines, pillars, railings, steps, corners, and sandblasting is also widely used in stone carving, which can often be seen in hotels, conference rooms, museums, corridors and other occasions.


Engraving board and special surface treatment

As long as the surface texture you can think of, it can be realized in the form of engraving. The decorative effect of the marble engraving board and special surface treatment is very beautiful and outstanding.


The introduction of the stone surface style is here. I believe that in the future development, as consumers understand and use the stone industry, the types of stone products will become more diverse!
