Different Levels of Polished Concrete

Polishing concrete includes many steps, some of the steps are extra steps to optimize shine and durability others are a must to achieve a properly polished concrete floor. The steps for polishing concrete can be reduced or increased depending on the budget for the job, the design outcome, or how the concrete was finished at the time of placing. When determining what steps are needed, I refer to three factors; shine level, stone exposure, and maintenance.

Steps for a basic concrete floor polishing (Medium shine 800 grit, salt and pepper stone exposure, and low maintenance):

  • 70 grit metals
  • 120 grit metals
  • 100 grit hybrid
  • Apply densifier
  • 200 grit resin
  • 400 grit resin
  • 800 grit resin
  • Seal with penetrating sealer

If the concrete was watered down at the time of placement this will cause small voids that need to be filled to achieve the best finish. To do this we add a step to grout the floor, so the above process will look like this:

  • 70 grit metals
  • 120 grit metals
  • Grout the floor
  • 100 grit hybrid
  • Apply densifier
  • 200 grit resin
  • 400 grit resin
  • 800 grit resin
  • 1500 grit resin (shinier)
  • 3000 grit resin (shinier)
  • Seal with penetrating sealer

If you want a basic polished floor and the concrete was not finished well or there are a lot of high and low spots we might need to add a step to grind more off by using a lower grit diamond (stone exposure will be increased). Here is an example of what the basic option looks like with doing a heavy grind:

  • 30 grit metals
  • 70 grit metals
  • 120 grit metals
  • Grout the floor (optional)
  • 100 grit hybrid
  • Apply densifier
  • 200 grit resin
  • 400 grit resin
  • 800 grit resin
  • Seal with penetrating sealer

Some floors call for a cream polish where very little of the concrete is ground down. The steps are reduced and the cost is the lowest (not all floors can have this finish). The steps could look like this for a cream polish:

  • Apply densifier
  • 200 grit resins
  • 400 grit resins
  • 800 grit resins
  • Seal concrete with penetrating sealer

As you can see polishing concrete can be done in different ways to achieve different results. A premium polish can have 11 or more steps, while a basic cream polish can be as little as 5 steps. Be sure when you choose to have your concrete floors polished to go over all of the different options. This steps will often be adjusted depending on the condition of the concrete.

What Customers Should Know When Shopping For Polished Concrete

Before hiring a contractor for polishing concrete, there are a few things you should know about. Saying you want polished concrete is almost like saying you want tile flooring, polished concrete is a relatively broad category . Like tile flooring, there are many options to choose from when you have your concrete polished. For instance, you can have large stones or small stones exposed in the initial grinding or you can have a very high shine (3000 grit finish) or a lower shine (800 grit). After the concrete is polished it is also recommended to be sealed to prevent stains. There are two main types of sealers used for polished concrete, a guard (film forming sealer) or a penetrating (non-film forming sealer).

So before you hire someone, make sure the contractor goes over all the steps and if a sealer will be used. If you just ask for a price for polished concrete with out stating the details, one contractor might give you a price to polish to a 800 grit finish and apply guard (it will enhance the shine), while another contractor might give you a higher price but it is for polishing to a 3000 grit level and using a penetrating sealer (will not enhance the shine).

Another Polished Concrete Floor In Garage

Polished concrete for a garage floor is an excellent idea if you are wanting a long lasting floor. Concrete polishing consist of grinding the concrete and then refining the concrete with finer and finer abrasives. This will give you a nice clean floor that is then sealed with a penetrating sealer. The penetrating sealers are easy to apply unlike an epoxy that typically has to be ground off and re-applied. When the concrete floor does need to be re-sealed it is as simple as cleaning the floor and spraying on the sealer.

The garage floor below was located in Boerne, Tx. The garage was 1700 square feet; we densified, polished the concrete to an 800 shine level, and then applied a sealer. We did not apply a decorative stain because typically the concrete will have a nice tannish color.

Polished Concrete in Garage

Polished concrete is a great option for garage floors. They will not peel or bubble like epoxies. Most average size garages can be finished within three to four days and can be driven on the next day. A decorative concrete stain can also be added to the concrete when polishing.

The polished concrete job we just finished was a 1600 square foot garage. We polished the concrete up to a 800 grit shine, densified the concrete, and then applied a penetrating sealer to the concrete.
