There are several steps a professional service takes in performing concrete polishing on a commercial or residential stone restoration floor project. First, they wash and clean the surface with heavy-duty chemicals. Then they use fine diamond grit sandpaper and high-powered commercial sanders to do away with the texture in the concrete. Concrete polishing can take a long time to complete, in order to make the surface completely flat. Once the surface is flat and there is a shine to it they will either stain it, paint it or use acid on the concrete. A coat or two of polyurethane is applied to keep the polish safe.
Concrete Polishing by Yourself
This is no easy task ask, you will most likely have to rent several pieces of equipment to complete a residential or commercial stone restoration project including:
- Floor buffer
- Professional floor grinder
Aside from the rental equipment you will need:
- Fine diamond sandpaper (these are discs or segments for the grinder)
- Power washer
- Concrete stain
- Hand grinder
The first thing you have to do is install the diamond grit paper to the grinding system. Use the grinder to make the floor as flat as possible. The diamonds that are in the paper will create a very flat, smooth surface with a nice sheen to it. You will most likely need to use a larger grit paper and work your way down to a very fine one. Corners are more difficult, and for this job you will need the hand sander. Once the grinding is finished, power wash the floor and let it dry. Grind it more if you need to, but if you don’t then continue on. Apply one to two coats of concrete stain. Let it dry completely until you get your desired color. When it’s dry put a topcoat of polyurethane on it to seal the color.
