Natural stone has high-grade texture and delicate texture, and is very popular as a finishing material for interior and exterior decoration of buildings.
In addition to giving people a unique natural artistic visual effect through natural texture, stone can also create ever-changing visual experience through various surface processing methods. Such rich changes are also one of the charms of stone.
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 to meet various design needs.
Such as marble, its surface finished is very important, because designers will choose the appropriate surface treatment form according to the type and pattern, hardness and characteristics of the stone, and then present it in the interior space. It can better ensure the effect of the design works, meet the design requirements of safety, functionality and aesthetics, and avoid some design problems.
There are many surface treatment forms of marble. From the perspective of non-slip, stain resistance, easy cleaning and collision resistance, different surface treatment methods can be extended. So, what are the more common stone surface processing methods in the industry?
According to the applications, it can be roughly divided into the following four categories:
1.The most conventional surface treatment, such as polished surface, honed surface, etc.;
2. The non-slip surface treatment, such as acid wash finish, flamed, water wash surface, bush hammered surface, pineapple surface, etc.;
3. That is decorative surface treatment, such as antique surface, grooved surface, mushroom surface, natural surface, sandblasted surface, acid antique surface, etc.;
4. The 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 wave carving and so on.
Below we will introduce to you one by one
-PART01- Familiar common surface treatment
Polished surface refers to the surface obtained by rough grinding, fine grinding and fine grinding of the flat plate with abrasives, and polishing with polishing powder and agent. The surface is mirror-bright, brightly colored, and has few and very small pores.
The luminosity of general marble can be 80 or 90 degrees, which is characterized by high luminosity and strong reflection of light, which can often fully display the rich and gorgeous colors and natural texture of the stone itself.
The honed surface refers to the smooth surface, and the surface is less polished with resin abrasives. Its luminosity is lower than that of the polished surface, generally around 30-60.
The matt-treated stone often has a certain luminosity, but the reflection of light is weak. It is a flat and smooth surface, but the luminosity is low.
-PART02- Anti-slip surface treatment
The acid wash surface achieves the visual effect by corroding the surface of the stone with strong acid. The treated stone will have small corrosion marks on the surface, which looks more rustic than the polished surface, and the strong acid will not affect the interior of the stone.
This process is common in marble and limestone, and has good anti-skid performance. It is mostly used in bathroom, kitchens, roads, and is often used to soften the luster of granite.
Flamed surface refers to the rough surface finish made of acetylene, oxygen as fuel or propane, oxygen as fuel, or high temperature flame generated by petroleum liquefied gas and oxygen as fuel.
Because the effect of burning can burn off some impurities and components with low melting point on the surface of the stone, thus forming a rough finish on the surface, so the hand will feel a certain thorn.
The flamed 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.
The surface of the stone is washed with a water jet machine, showing unevenness, but the surface is smooth without edges and corners, similar to the acid wash surface, but the surface color is close to the smooth surface, slightly darker than the acid wash surface, and the water absorption rate is small.
The bush hammered surface is made by hitting the granite surface with a hammer shaped like a lychee skin. This processing method can be divided into two types: machine-made surface (machine) and hand-made surface (handmade). Generally speaking, hand-made noodles are more dense than machine-made noodles, but they are more laborious and the price is relatively high.
The method of pineapple surface is to process the stone surface to be more uneven than the Bush hammered surface, and the graininess is more obvious. The texture of the material is just the opposite of that of the washed surface, with weaker bumps and larger graininess.
-PART03- Decorative finish
The antique surface is to eliminate the thorny characteristics of the surface of the burned surface. After the stone is first burned, then brush it with a steel brush 3-6 times, that is, the antique surface. The antique surface has the concave and convex feeling of the burnt surface, and it is smooth to the touch and will not sting. It is a very good surface treatment method. The processing of antique surface is time-consuming and expensive.
The grooved surface is also called "pulling groove" or "drawing wire", which is a groove with a certain depth and width on the stone surface, usually a straight line groove, with two-way grooved (5mm × 5mm) and one-way grooved If required, the water jet can also be used to draw the curved notch, but its material cost is high.
In order to avoid accidental injury, the passivation treatment of the notch should be considered in this approach, and grinding can be done if necessary.
The recently popular format elements can be used to process stone in pull groove surface.
Mushroom surface refers to a plate that is shaped like an undulating mountain by hitting with a chisel and a hammer on the stone surface. This processing method has certain requirements on the thickness of the stone. Generally, the bottom should be at least 3 cm thick, and the raised part can be more than 2 cm according to actual requirements. This type of processing is common in economical enclosures.
The natural surface is commonly known as the natural fracture surface and the cracked surface. It is a piece of stone that is naturally split from the middle by machinery, and no treatment is performed after the split. The surface of this stone is extremely rough and extremely uneven tension.
Natural-faced stone should also consider the relationship between the weight, thickness, specifications and installation process of the stone, which is suitable for spaces with natural and rough styles.
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), resulting in a similar glass. Frosted stone surface processing method.
At present, the process is generally realized by stone sandblasting machine, and the airflow size can be adjusted according to the hardness of the stone to achieve the required depth and uniformity.
The processing way can make the stone material has good anti-skid function, at the same time and do not break beautiful, so the application range is very wide, not only can be used for sheet, specification sheet plate and other natural stone products processing, can also, railings, stairs, corner line, pillars and special shape stone processing, and sandblasting processing is also widely used in stone carving, It is often seen in hotels, conference rooms, museums, corridors and other occasions.
-PART04- Engraved tiles and special finishes
As long as the surface texture you can think of can be realized in the form of engraving plate, the decorative effect of marble engraving plate and special surface treatment is very beautiful and excellent.
Crocodile skin engraving
water wave engraving
It is believed that in the future development, as consumers know more about and use the stone, the types of stone products will only become more and more diverse.
