Etching repair Process

The etching process depends on how deep the etching has gone into the marble or stone. The first step is to try and remove the etching with polishing powders; this is done with a hand machine, soft pads and a bit of water. The powder has little bits of grit that tries to scratch away the etching. If this is successful, then it is complete. However, if it is still there, then we go through with diamond pads and polishing. The diamond grade depends on the severity of the etch. For example, if it were a two hundred grit, we would follow all the way up to a 1500 grit done with a hand machine. Once this has been done we apply polishing powders and machine polish and rinse the area
