Handling granite renovations, why not shine after polishing?

Granite, commonly known as granite, is mainly composed of minerals such as quartz, mica and feldspar. The Mohs hardness is about 6.5. Although it has a hard texture, granite tiles are prone to weathering and wear after long-term use, especially in the case of frequent water contact. At this time, a small amount of concave pitting appears on the surface of the stone, and there is a concave and convex feeling when touched by hand. When the pitting is increasing, the surface brightness of the granite is reduced and the original luster is lost. At this time, it is necessary to restore the luster of the stone by refurbishment.

However, there are often many problems after the renovation of granite stone. The common problem is that it cannot be lit up after renovation. Many people react that the polishing agent can't be done. If you change the medicine, you can get out of it, but if you change the medicine, you still can't emit light. What is going on? In fact, the refurbishment of granite has corresponding requirements for various aspects such as construction process, machinery and equipment, materials, etc. No matter which aspect is not operated according to the specifications, it is difficult to illuminate after renovation.

Why is the polishing not bright after the granite is refurbished? First analyze from the construction process:




First, we should consider whether the granite has been used in the whole construction process, especially if there is any stone protective agent before the water is polished. Domestic granite manufacturers




If the protective agent is not applied, the water will enter the interior of the stone during grinding, which will not only cause the problem of polishing, but also cause other problems such as water spots and rust yellow. In addition, the solvent-based protective agent should be applied before the polishing process, and if it is not applied, the polishing effect will be affected. Granite stone production




Second, we must analyze whether there is a phenomenon of jumping in the process of granite renovation. There are two cases of the jumper mentioned here, one is that the number of the grinding plate is not increased step by step. For example, if 150# directly grinds 500#, the middle 300# is omitted, which will not only affect the effect of post-polishing, but if the dark granite omits 300#, it will also cause the color to be unrecoverable.

In the second case, the jumper refers to the use of refurbished hard film in the early cutting, and the fine grinding of the water in the back, so that the scratches left by the previous cutting can not be eliminated, which will cause the polishing to be not bright. Granite specification


Third, there was no timely water absorption during the renovation process. This problem is often overlooked. If it is not possible to absorb water every time it is finished, the scratches will not be completely eliminated after the grinding, which will directly affect the later polishing. Granite type


Second, analyze from the polished material:


1. “Workers must first sharpen their tools if they want to do their best”. For granite renovation, choose a special grinding machine for stone, and do not use non-professional equipment such as scrubbers.


2. When the granite was refurbished, there was no special refurbished piece.


3. The refurbished granite is polished on the basis of polishing.


It can be seen from the above analysis that the factors that can not be polished after the refurbishment of granite are not only materials, but we can analyze them one by one from the aspects of “people, machine, material, ring, law, book”. Decorative granite


Among them, the key influencing factor is actually people. Granite refurbishment has high technical requirements for construction workers. The machine needs people to operate. The materials need people to choose. The process needs people to formulate, implement and supervise.


Therefore, if you need to deal with the granite renovation project, you must first train the construction personnel to let them master the standard process of granite renovation.
