marble surface treatment

1. Rough grinding

groove joints before grinding, then waterproof, and then fill joints. After the waterproof effect comes out, use 50 #, 150 #, 300 # dry grinding. After 300 # water spray grinding, 300 # and 500 # use diamond resin hard grinding blocks (rough grinding, do not use soft water grinding plate for grinding, which is prone to waves and affects the flatness). Remember not to use too much water for rough grinding. It is best to use the method of spraying. After each grinding plate is polished, mop it up with a mop, completely suck up the water, check whether the deep scratches left by the cutting grinding are ground off with 50 # grinding plate, and so on. The machine goes through well grinding, Rough grinding accounts for 45% of the overall grinding time, which is the key link to ensure the quality acceptance of the project completion

2. Fine grinding

3. Fine grinding

the stone must be 70% dry before grinding. First, use natural stone sealing agent (ionic water A10) for pretreatment, so that the stone can not only fill the porosity, but also strengthen the material. Then use 2000 #--3000 # diamond resin soft water grinding plate to spray A2 for grinding, dry it, and then continue to dry grind it to produce brightness. This process is to fill and seal the stone and ion exchange. Fine grinding accounts for 20% of the overall grinding time. After fine grinding, the gloss is improved very high, and the surface density of marble is increased, which lays a solid foundation for the polishing agent (no2+q5 mirror repair agent) and enhances the adhesion of polishing materials

4. Polishing

polished stone must be thoroughly dried. (drying method: use a mobile drying oven for drying, and the dryer power of about 4800 watts is the most suitable.) The power of the crystal surface machine is more than 2HP (1500— — 1800 watts), the rotation speed is 175-210 rpm, the weight is 45-70 kg, and the animal hair pad with 70% animal hair content, 3M pad, nano pad, etc. can be used. It can be polished and grinded in combination with the marble mirror face restoration cream NO2, 2x mirror lock brightening lead-in milk Q5. The gloss of the polished marble surface can be at least 90— Above 100 degrees

marble surface crack repair method

1. The width of the surface crack is less than 1mm

a. remove the foreign matters in the crack with a blade, blow out the impurities in the crack gap with an air gun, clean the surface to be repaired

b, polish and fill the crack surface with white wax (the color of the wax block can be adjusted according to the table top color, but also black) blocks, so that the white wax completely covers the gap, and bake with a blower to make the white wax melt into the gap

c. Scrape the repaired surface with a sharp notchless blade. The visual stone is consistent with the whole, and there is no obvious abnormality

2. The width of the surface crack is greater than 1mm and less than 3mm, and the length is longer

a. remove the foreign matters in the crack with a blade, blow out the impurities in the crack with an air gun, and clean the surface to be repaired

b, mix and stir the marble glue and curing agent at the ratio of 10:0.8. After use within 5 minutes, the color of marble glue can be mixed, which needs to be similar to the color of the table

c. Fill the crack with mixed glue, wait for about 20 minutes to be completely dry, and then polish it with sandpaper from low grade to high grade. (such as 320 #-500 #-800 #-1000 #-1500 #-2000 # sandpaper), dry grind with sandpaper, and finally polish the repaired part back and forth with steel wool dipped in polishing wax. The visual gloss is consistent without obvious traces

3. The diameter of the surface hole is less than 3mm and more than 1mm

a. remove the foreign matters in the crack with a blade, blow the impurities in the crack with an air gun, and clean the surface to be repaired

b. Use electric chromite with a power of 50W to take a rubber block the size of a pit from the stone glue, melt it in the part to be repaired, scrape the repaired surface with a sharp notchless blade, and then polish it with sandpaper from low grade to high grade. There is no bump in visual and hand feeling

c. Polish the repaired surface back and forth with steel wool dipped in polishing wax, and the visual gloss is consistent without obvious traces

selection of marble

1. Check certification: for a product, first of all, check whether it has ISO quality system certification, quality inspection report, etc. the first step is to prevent yourself from being cheated

2. Eyes: generally, the surface color of artificial marble with good quality is relatively pure, and there will be no small pores on the back of the plate

3. Touch with your hand: the surface of high-quality artificial marble will have a very obvious sense of silk, and the surface is very flat, while the poor one does not

4. Nose smell: inferior artificial marble will have a very obvious pungent chemical smell, while high-quality marble will not

5. Nail scratch: I believe many people have tried this method, which is indeed a more effective method. High quality artificial marble, with nail scratch, will not have obvious scratches

6. Mutual knocking: you can choose two marbles of the line and knock each other later. If it is easy to break, it is inferior. If not, it proves that the quality is better

editor's summary: This is the end of the introduction of marble surface treatment and marble surface crack repair methods. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
