Four Levels of Polished Concrete Floors
2021-07-13

Polished concrete is using large grinder to mechanically grind, hone, and eventually polish concrete. The large grinder with concrete floor diamond tooling can polish a concrete floor to a specified level of shine.


There are 4 levels of polished concrete floors.

Level 1 Flat
This is a very dull shine. We can usually achieve this by stopping the polishing process at or below 100 grit.
Level 2  Satin
The concrete floor is just starting to get some really good shine during this phase. It is stopped after the 400 grit. If looking about 100 feet away, you can start to see the ceiling. Not very much clarity though. This is a really good matte finish for polished concrete.
Level 3  Semi-Polished 
A level 3 polish stops after 800 grit. It has a much higher sheen compared to a level 2 shine and also has much more clarity. When standing back 30-50 feet, the floor will clearly reflect lighting from the ceiling and walls.
Level 4  Highly Polished
A level 4 polish produces a very high shine both when standing directly over the surface and from a distance. It will be able to see the reflection with total clarity. The floor will appear to be wet when viewed from different angles. A level 4 polish is achieved by polishing up to a 3,000 grit using resin bond diamond tools or by burnishing the floor with a high-speed burnisher.


Benefits of Polished Concrete Floors:

1. Beautiful, through polishing, various pre-added aggregates in the concrete are presented, with a certain decorativeness.

2. Environmental protection, sustainable, raw materials are environmentally friendly and pollution-free, and can directly polish the existing concrete floor, which is an environmentally friendly floor solution. Moreover, it has been proved through practice that high-reflectivity polished concrete floors can increase natural brightness and have a certain effect on reducing lighting energy consumption.

3. Hygiene and no dust. The sealing curing agent acts on the concrete and can inhibit the precipitation of dust from the surface pores for a long time. It can also reduce allergens and inhibit the growth of mold.
