Granite Stone Surface Treatment Process

Granite Stone Surface Treatment Process

At present, there are mainly four kinds of stone on the market: marble, granite, terrazzo and synthetic stone. Due to the color differences and appearance defects of natural stone, the product needs to be typeset to achieve a perfect decorative effect. The quality of the stone typesetting effect directly relates to the overall decorative effect. Granite is harder than marble; terrazzo is made of forging materials such as cement and concrete; synthetic stones are made of crushed stones of natural stones, plus binders, etc., which are pressed and polished. Because the latter two are made by hand, the strength is not as high as that of natural stone.


1. Glossy (polished)

Smooth surface refers to a flat surface, which is polished on the surface with resin abrasives to make it have a mirror gloss. The general luminosity of stone can be 80 or 90 degrees, and the luminosity of some types of stone can even be more than 100 degrees. Natural stone has a hard texture, colorful, simple and elegant, shock resistance, acid resistance, weathering resistance and good polishability Features. Due to its many advantages, the application range of stone is getting wider and wider, and the amount of stone is increasing, which plays an important role in human life. Generally speaking, the higher the brightness, the higher the price.

2. Matte surface (honed)

Matte surface means that the surface is flat, and less polishing treatment is performed on the surface with resin abrasives. The brightness is lower than the polished surface, generally around 30-50, 60. It has a certain luminosity, but the reflection of light is weak. The surface is flat and smooth, and the luminosity is very low. The stone is a natural building material. The entire surface of the earth is composed of rocks, and the rock is formed by many mineral groups combined in various ways-a rock contains minerals of different hardness .



3, Flamed

Fired surface refers to the rough surface finish made by processing the surface of the stone with high temperature flame generated by using acetylene, oxygen or propane, oxygen, or petroleum liquefied gas, oxygen as fuel. There are a few stones that cannot be processed by fire or that the processed results are not good. Due to the effect of fire, some impurities and low-melting components on the surface of the stone can be burned off, thereby forming a rough finish on the surface, which will have a certain tingling sensation when touched by hand. The processing of the fired surface has certain requirements on the thickness of the stone to prevent the stone from cracking during the processing. Generally, the thickness is required to be at least 2CM, and some stone thickness requirements are higher.
