Marble is a valuable substance, which is usually used as building decoration material, interior decoration, Renaissance sculpture and so on. It is not only durable, but also beautiful. However, due to the vulnerability to impact, wear and aging, the appearance is damaged or dim. Fortunately, there are some ways to repair and protect marble walls, including repairing and polishing. Here are some suggestions:

clean the surface

First, clean the marble wall. You can use ordinary cleaning products such as soap and water or special marble cleaning products. If there is serious dirt or stain on the surface, it can be cleaned with marble cleaner or abrasive.

Filling and repairing

If the marble wall is cracked or damaged, it can be repaired with marble filler. The filler should be adhered to the stone and leveled with a millstone before drying to ensure smooth surface.

Grind the surface

Polishing is the key to restore the original luster of marble. A grinder, a hand-held grinding wheel or a manual grinder can be used. First, grind the surface with coarse grinding wheel, and then grind the surface gradually with fine grinding wheel until the required gloss is achieved.

Protective surface

In order to protect marble, transparent natural stone protectant should be used. The protective agent can fill the cracks and pores on the stone surface and prevent the liquid from infiltrating into the stone. In addition, it can also prevent the marble surface from falling off, coloring or yellowing.
