When considering ways to improve the look of your concrete floor, a common suggestion by Yonkers, New York concrete companies is to polish the surface by grinding it down until it shines. However, you should be aware that there are two types of polishing techniques – wet and dry. The wet process uses water to cool the diamond abrasives that grind the surface. This eliminates grinding dust and helps the machine last longer. However, it generates a clay-like residue which needs to be cleaned up and can slow down the process. Alternatively, the dry process involves no water, but a layer of dust is created. In many cases concrete contractors in Yonkers can use both methods and alternate between them as needed.
