Stone refurbishment is part of stone maintenance and consists of three steps: rough grinding, fine grinding and polishing. The steps of renovating the floor refurbishment floor, each step is carried out with the use of diamond abrasives.

1. Rough grinding will remove scratches, corrosion, and traffic marks on the surface.

2, fine grinding, smoothing the ground and grinding the surface.

3. Polished, diamond abrasive will polish the surface. The water is constantly flowing as a lubricant for diamond.

The specific operation details have the following parts:

1. Base treatment:

(1) The large terrazzo machine is equipped with a coarse diamond grinding head water mill to smooth the ground and completely remove the epoxy resin coating.

(2) The large terrazzo machine is equipped with a fine grinding head water mill to ensure a smoother and smoother surface.

(3) Wash and remove clear water, and dry naturally for 3-7 days.

2, cement floor sanding agent A component construction

(1) Dilute component A with appropriate amount of water on the ground according to the ground conditions. The amount of raw liquid: 0.2-0.5kg/m2.

(2) When the surface has no clear water or becomes viscous, spray a small amount of water in time to keep the surface moist to promote penetration. The above operation lasts for about 4 hours. Finally, rinse the surface with enough water to remove the surface water and dry naturally. More than an hour;

(3) If the ground strength is poor, repeat the above steps after 24 hours.

3, cement floor sanding agent B component construction

(1) spraying the component B solution, the dosage is about 0.2-0.5kg/m2;

(2) When there is no clear water on the surface layer, spray a small amount of water in a timely manner, keep it moist for about 4 hours, and finally rinse with plenty of water (preferably rinse with a hard brush while washing), and remove the surface water, and dry naturally.

For the above 2 and 3 steps, it is best to use an electric washing machine with a high-power water absorbing machine for higher efficiency and better appearance.

Grinding and polishing of marble grinding blocks is the first process of stone care crystal surface treatment. The weathering resistance is poor, so the worn surface is easy to lose luster. The marble can be refurbished according to the degree of wear on the marble surface, with a mild, medium and deep marble grinding and refurbishing method. Here’s how to polish the marble renovation process.

1. Thoroughly clean the ground, remove the concrete slurry at the gap of the stone with a knife, and then thoroughly remove the dust with a brush, vacuum cleaner, etc. Clean with a dry and clean ground, no sand or impurities on the ground.

2. After the overall cleaning of the stone surface is completed, the small damaged points and the stone joints on each stone are repaired with marble glue. Firstly, the original damaged surface is repaired with marble glue close to the stone color. Then use a special stone slitting machine to re-align the slits of the original stone installation to make the width of the gap uniform, and then fill it with marble glue close to the stone color. After the marble glue is repaired, it must be dried before the glue can be dried.

3. After the marble glue is dried, use the sander to polish the whole ground, and polish the whole horizontally. Focus on the caulking between the stones and the edge of the wall, the decorative shape and the special shape to keep the whole stone floor level. Finish the first polishing, re-cast the marble glue caulking, continue the second grinding with the caulking, and then use the stone refurbished machine with the water refining sheet from coarse to fine. A total of seven grinding and polishing is required. It is smooth and smooth, and then polished with steel wool. The polishing degree reaches the brightness required by the design, and there is no obvious gap between the stones. (Granite refurbishment must use bridge mills and professional grinding discs. Resin grinding discs should not be used. Rough grinding: Do not reduce the number of grinding passes and change the number of grinding discs. 60-mesh grinding discs are used to polish the stone floor, the height difference, The color of the glue such as scratches and deformations is basically the same, and must be full. Fine grinding: Do not reduce the number of grinding passes and change the number of grinding pieces.)

4. After the polishing is completed, use the water absorbing machine to treat the moisture on the ground. At the same time, use the blow dryer to dry the whole stone floor. If time permits, you can also use natural air drying to keep the stone surface dry.

5. Spray the syrup evenly on the ground side, use a marble polishing machine to grind it, use a washing machine with a red scouring pad, spray the syrup with the same amount of water on the ground, start grinding, and heat the crystal surface material on the surface of the stone. The surface effect formed after the formation.

6, the overall ground maintenance treatment: If it is a large void stone to be marble protective agent painting, re-polishing once, in order to increase the hardness of the entire surface of the crystal face.

7. Ground cleaning and maintenance: When the stone surface is formed into a crystal mirror surface, use the vacuum cleaner to absorb the residue and moisture on the ground. Finally, use the polishing pad to polish, so that the whole ground is completely dry and bright as a mirror. If partial damage can be used for local maintenance, Construction can be done at any time. (After the surface of the stone is dried, it is hardened by crystallization until the surface effect required by the sample is achieved. The refractory travertine surface reaches a mirror gloss of 60 degrees or more, and there must be no height difference between the stones, and the granite surface is achieved. Above 80 degrees, there must be no leakage.)

Many of the peers who do stone care, when choosing the initial grinding sheet, are often selected according to the height of the ground cut. When we conduct on-site inspection, we find that the height of the panel is mostly above 3MM. The 30-mesh grinding disc will be selected for the trimming and smoothing treatment. If the height between the stone plates is below 3mm, then we generally choose 50 mesh for processing.

But is this really reasonable and correct? From the perspective of professional specifications, we choose the starting grinding sheet. The high and low cutting between the stone plates is an important basis for our choice, but it is not the only basis. We also need to refer to the physical properties of the stone to determine. The physical and chemical properties of stone include: bulk density, water absorption, Shore hardness, compressive strength, and the Shore hardness of these four items is directly related to our choice of grinding disc. The Shore hardness of stone is a special name for reflecting the hardness of stone. It is the data obtained by the authoritative organization through experimental testing. The higher the data, the higher the hardness of the stone. It is more difficult to grind directly on the grinding. The grinding needs to be more rounded. It is necessary to choose a sharper grinding piece (the smaller the grinding piece, the sharper it is). The smaller the Shore hardness data, the lower the hardness of the stone and the easier it is to grind.

After understanding the physical and chemical properties of the stone, we know that the selection of the grinding sheet should not only be based on the height of the stone, but also the hardness of the stone. The height of the floor is very large, but the hardness of the stone is very low. The original grinding piece does not need 30-mesh or 50-mesh grinding pieces. We can directly select 150 mesh or even 300 mesh. For example, when encountering white sand beige stone (its Shore hardness is 33), no matter how high or low the cut is, we can start grinding with 300 mesh. For stone like American white hemp, its height is not big, but we usually choose to start from 30 mesh because its Shore hardness is 109. After understanding these, the following is a comprehensive consideration when selecting the grinding disc according to the unevenness of the ground and the Shore hardness. This not only improves the efficiency of the work, but also reduces the material cost.

We must pay attention to a problem when choosing a cut-off grinding piece, that is, the grinding piece should be targeted and professional. What is the reason for this? In fact, grinding marble should choose marble professional grinding discs. Grinding granite series stone should choose granite professional grinding disc. Grinding and polishing brick series should choose polishing disc special grinding disc. If marble grinding is used to grind granite, we know that the cutting is flattened too slowly, the efficiency is low, and the labor cost is increased. When the granite is used to grind the marble, the speed of the smoothing of the cut will be increased, but the grinding loss will be fast and the material cost will be greatly increased. The special grinding discs of marble or granite are used to grind the polished brick floor, which may not be ground. The grinding sheet will slip, that is, it will be ground up, and the scratches of the grinding sheet will not be eliminated. Give us the subsequent process belt. Come a big problem.
