Natural stone,besides the natural texture character,it brings people a unique natural artistic visual effect by various surface treatment

methods.Stone surface treatment means applying different treatments to its surface to ensure the safety of the stone itself.

Making itself show different material styles to meet various design needs.

Taking natural marble stone as a example,there are many surface treatment methods. From the perspective of non-slip, stain resistance, easy cleaning and anti-collision, different surface treatment methods can be extended.What are the more common stone surface processing methods in the stone industry?

According to the actual usage, it can be roughly divided into the following four categories:

01)The most common surface treatment, such as polished surface, honed surface, etc.;

02)The second one is anti-slip surface treatment, such as pickling surface, flamed surface, water-jet surface, ushhammered surface, pineapple surface, etc.;

03)The third one is decorative surface treatment, such as antique surface, cloth surface, grooved surface, mushroom surface, natural surface, sandblasted surface, acid antique surface, etc.;

04)The fourth one is the engraving and special surface treatment, as long as the surface texture you can think of can be realized, such as crocodile skin carving, water pattern carving and so on.

01) Now,let's talk about the common surface treatment firstly:

1.Polished surface

Polished surface refers to the surface obtained by rough grinding, fine grinding and fine grinding with abrasives and polishing powder. The surface is mirror-bright, brightly colored, and has few and small pores.

The polish degree of general stone 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.

2. Honed surface

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 honed-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.

02)Anti-slip surface treatment:

1. Acid :The acid 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 widely used for marble and limestone, and has good anti-sklip performance. It is mostly used in toilets, kitchens, and roads, and is often used to soften the luster of granite.

2.Flamed surface

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. 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.

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

3.Water-jet surface:

The bushhammered surface is made by hitting the granite surface with a hammer shaped like a bushhammered skin.

This processing method can be divided into two types: machine-made bushhammered (machine) and hand-made bushhammered (handmade). Generally speaking, hand-made bushhammered are more dense than machine-made bushhammered, but it is more laborious and the price is relatively high.

5. Pineapple surface:

The method of pineapple surface is to process the stone surface to be more uneven than the bushhammered 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.

03)Decorative surface

1. Antique surface

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.

2.Grooved surface:

The grooved surface is also called "pull groove" or "wire drawing", which is a groove with a certain depth and width on the stone surface, usually a straight line groove, with two-way groove (5mm × 5mm) and one-way groove. If required, the water jet can also be used to draw the curved notch, but its material cost is high.

3.Mushroom 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.

4.Natural-split surface:

The natural-split 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.

5.Sandblasted surface:

The sandblasted 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.

04)Engraving and special finishes treatment:

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.
