2、Concrete polishing has different designs,such as colors,patterns etc

3、Levels of concrete polishing lead to the reflection of concrete floor

4、Polished concrete is popular because it last long and is easy to maintain

Simply but polishing concrete is similar to sanding wood. Heavy-duty polishing machines equipped with progressively finer grits of diamond-impregnated segments or disks (akin to sandpaper) are used to gradually grind down surfaces to the desired degree of shine and smoothness.

1、First use coarse grit metal bond diamond segments to remove stains and coatings from the old floor

2、Second use fine grit resin bond diamond pads to polish the floor to a degree shine.

3、For an extremely high-gloss finish, a final grit of 1500 or 3000 may be used.

Experienced polishing crews know when to switch to the next-finer grit by observing the floor surface and the amount of material being removed.

Polish concrete can be use wet or dry. mostly are dry because it is faster and convenient,environment friendly. wet use is inconvenient with cleanup

Many contractors use a combination of both the wet and dry polishing methods. Typically, dry polishing is used for the initial grinding steps, when more concrete is being removed. As the surface becomes smoother, and crews switch from the metal-bonded to the finer resin-bonded diamond abrasives, they generally change to wet polishing.

Step-by-Step:

Remove existing coatings (for thick coatings, use a 16- or 20-grit diamond abrasive or more aggressive tool specifically for coating removal)

Seal cracks and joints with an epoxy or other semi-rigid filler.

Grind with a 30- or 40-grit metal-bonded diamond.

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.

Polish with a 400-grit resin-bond diamond.

Polish with an 800-grit resin-bond diamond.

Finish with a 1500- or 3000-grit resin-bond diamond (depending on the desired sheen level).

Optional: Apply a stain guard to help protect the polished surface and make it easier to maintain
