First, the marble is polished and wet
nbsp？ 1, clean and dry marble surface. Soak the soft cloth in the foam mixture of neutral detergent and water, and then wring the cloth to remove excess water. Clean the whole area where the scratches are located, and make sure that there is no dust, dirt, debris or anything else on the marble. Then, wipe off the residue on the soap with a second cloth soaked in water, and wipe the marble with a third dry cloth.
If there is dust or debris on the marble surface, it will be worn off when it is polished, and eventually it will be scratched or even more serious.
Although you will wet the marble before polishing, drying it first can ensure that there is no soap residue or dirt to scratch the marble.
2. Soak the marble surface with a spray bottle. Fill a clean sprinkler with boiling water and spray a small layer of water on the marble. By wetting marble before polishing it, dust can be attached to it and turned into paste instead of flying into the air and being inhaled.
Water will make the marble look darker, but don't leave a permanent mark unless you let the puddle stand for a few hours.
If you choose to dry marble, please wear goggles and a dust mask with a gas mask to avoid inhaling dust from the stone.
3. Connect the grinding wheel with granularity of 1000 to the electric sander. Sandpaper should be easy to install on the sander, but make sure it is installed firmly. If sandpaper bends at the edges, it may scratch marble. Sand tables can be bought anywhere where sellers install products.
If the scratch is small and you don't want to use power tools, you can do it manually. Use 1000 grit sandpaper to polish gently in circles.
If there is no electric sander, please buy a cushion suitable for drilling, and then connect sandpaper to the cushion.
For deep scratches, it may be necessary to grind them with coarse sandpaper to 1000 coarse sand first, but in this case, it is usually best to seek professional advice rather than risk damaging the marble surface.
4. Turn on the grinder and polish around and above the scratches. Put the surface of sandpaper on the marble, but don't press the sander hard. The weight of the tool and the movement of sandpaper are enough to polish off scratches or etching marks on the surface. Move the tool in a slow circular motion, focusing on a smaller area at a time.
Pressing the grinder hard may scratch or damage the marble.
Scrub until the scratch is smooth.
5. When polishing marble, please continue to spray marble with water. When grinding regularly, lift the sandpaper and spray another layer of water on the workbench. This will prevent the marble from drying out.
If marble dries, you may scratch it when grinding because of the paste formed by marble powder.
6. Wash the marble with clear water. After the scratches on the marble are polished, pour a small amount of water on the surface and then wipe them off with a clean wet cloth. Clean the area thoroughly, just like you left any sandpaper residue, which may also corrode the surface.
After the scratches disappear, the area can be polished to restore luster.
Second, gently polish it.
nbsp？ 1. Sprinkle a thin layer of polishing powder on the newly polished place. When the marble is still wet, dig out a thin and uniform layer of marble polishing powder according to the instructions on the package. You don't want the dust to dry, so if you are doing a big project, please cover a part of the marble with dust.
Marble polishing powder is usually made of tin oxide and is also used to polish glass and jewelry. Besides, it is insoluble in water, so you will get a smooth and even makeup.
Marble polishing powder can be bought in hardware stores or shops selling stone processing supplies. Be sure to check the label to make sure it is the correct type for a particular type of marble. If you are not sure what type it is, please consult a marble expert.
2. Connect the polishing pad to an electric sander or electric drill. After the powder is sprinkled on the table, connect the polishing accessories to the sander or drill. It should be placed like a sand table, but the surface of the polishing pad should be flat and smooth.
You can manually polish the countertop as needed, but it will be much easier if you use a sander or a fixed track drill.
If there is no polishing pad, use a soft wet cloth, such as microfiber cloth.
3. Run the sander at low speed to polish the marble surface until it is smooth. Polishing the countertop is just like polishing, but it makes the marble smooth rather than worn. When moving back and forth on the polishing powder, move the polishing machine in a circular manner. Keep polishing until you see a smooth, shiny appearance.
Polishing powder should be kept slightly wet, but it doesn't have to be soaked. If it looks too dry, please spray it gently with a spray bottle.
4. Clean the marble polishing paint with a soft dry cloth. Because the marble polishing agent is composed of tiny abrasive particles, it should leave a luster after completion. However, if the residue is left on the marble, it may corrode the surface for a long time, leaving new scratches and needing polishing.
You may not see the residue, but if you put your hand on the marble, you will feel the residue. If the surface feels hard after cleaning, please rinse the area with a little water and then wipe it with a new cloth.
Third, prevent future scratches.
1, sharp objects stay away from any marbles. The easiest way to avoid scratches is to keep sharp objects away from the marble surface. Knives and scissors are the obvious culprits, but feathers, sewing needles, jewels and other hard and sharp objects can also easily leave scratches on marble.
If your kitchen has a marble countertop, be sure to use a strong chopping board when cutting vegetables.
2. Clean up the spill as soon as possible. If you accidentally spill something on the counter, especially something acidic, such as coffee, juice or wine, please wipe it with a soft cloth immediately. Acid spill will corrode the marble surface.
Always clean up any spill on marble immediately, whether it is acidic or not. If a place accumulates water for too long, it may even lead to the discoloration of marble. If there are still stains, you can try rubbing the marble, which may lead to scratches.
3. Use mild detergent and water for daily cleaning. Rough household chemicals will permanently corrode stone, leaving traces that will aggravate the appearance of scratches. Wipe the counter with a damp cloth every day and use soap and water for deep cleaning as needed. You may need to cook once or more times a week, depending on how often you cook.
Although vinegar is an excellent natural household cleaner, it should not be used on marble. Even simple vinegar is acidic enough to corrode the surface of marble.
Dishwashing detergent is a good choice for cleaning marble.
4. Choose a paste made of baking soda and water to remove stains. If you dye marble, please add a little water to a little baking soda until it becomes paste. Apply the thick paste directly to the stain. Cover the area with a bowl or plastic sheet, leave it for about 24 hours, and then rinse it with cold water.
Don't scrub the paste, or you will scratch the marble.
