For a more economical floor finish while maintaining a high degree of aesthetic appeal, more and more people are turning to ground or polished concrete.
Concrete can be ground down to expose the aggregate, either the smaller sand on top, or deeper to see the larger aggregate. It all is up to the designer. The lighter “sand finish” provides a look like a sealed concrete floor, but still has some variation to it. The deeper grind or “aggregate finish” provides a look that is similar to a terrazzo floor, showing both the large and small aggregates that make up the concrete floor.
Polishing concrete is taking the finish of an existing concrete floor to a very high degree of shine by lightly grinding or sanding the floor with specialized machines. These machines use diamond pads to smooth the floor until a high shine is produced. The use of concrete stains can also be incorporated into this process as well.
