How do you grind and polish a concrete floor?

Grind with an 80-grit metal-bonded diamond. Grind with a 150-grit metal-bonded diamond (or finer, if desired). Apply a chemical hardener to densify the concrete. Polish with a 100- or 200-grit resin-bond diamond, or a combination of the two.

Then, how much does it cost to grind and polish concrete?

Economical: You can expect to pay between $3 and $12 per square foot for polished concrete, depending on your location and the complexity of the project. Polished concrete pricing is basically dependent upon how many levels of grinding will be required to get the floor to a suitably smooth surface.

Also, how long does it take to polish a concrete floor? After the surface is polished with a 150-grit, a chemical hardener is added to the floor. After that progressively finer grits are used to achieve the desired levels of gloss. Depending on the area, the level of polish, and the obstacles, the polishing can take upwards of 2 to 3 days.

Likewise, people ask, can I polish existing concrete floor?

Almost any structurally sound concrete floor, whether new or old, can be polished. But there are some exceptions. For new floors, no special mix design is required to achieve good results. However, the floor should be in place at least 28 days before polishing begins to ensure adequate curing.

  • Grinders and Polishers:
