Can All Concrete Be Polished?

By William Borris

Not too long ago, I was called by this person who wanted to inquire about concrete polishing. He seemed welcome to the idea, but had reservations just the same. He wasn't sure if the concrete at his home was fit for polishing.

I felt the need to address this. Are all concrete floors fit for polishing? The short answer would be yes, but I believe that a more descriptive answer is needed.

Okay, so this is the basic information. Concrete polishing is a process by which the surface of your concrete is cured, thereby hardening it, as well as providing a sleek, clean finish. To this end, most contractors treat the floor with a process called coarse grinding first.

Now almost all concrete will be shined, but there are concrete types that won't produce optimal results. The most obvious of these are the ones with as lot of patchwork done to them. Even if it were fixed beforehand, the marks of the patchwork will remain, and the concrete will not look as good as you want it to be.

On the other hand, porous concrete makes very poor polished concrete. There would simply be too many holes, and the concrete will not close properly post-polishing. When you are in the process of applying new concrete, then, talk to your contractor to avoid it becoming porous.

Speaking of new concrete, there is also a general rule to be followed when attempting to polish newly-laid concrete. Basically, you should wait for a grace period of about a month to let the concrete cure. At which time, assuming it was laid down properly, then polishing would be very easy to do.

There you go. Practically every piece of concrete can be polished. The only exceptions would be those that are not properly placed to begin with, and those that are too new to be touched.
