How do you get a burnished concrete finish?

Burnished concrete is the polished concrete finish where there is no aggregate exposed. This is achieved by a few steps. First the concrete when placed must be placed as level as possible as we are not removing any material from the surface any high's and lows will remain in the concrete. If your floor isn't laid flat when you look across it, it will look like the ripple of an ocean.

When using the helicopter the concreter needs to burnish the concrete until black, your concretor should understand what we mean by this term and this will start the polishing process. We arrive two weeks later to continue the polishing process. The concrete needs to cure for two weeks before we start working with it. If you use a higher MPA this can reduce the time however we recommend using a minimum of 32MPA for a burnished finish.

 It is important that the concrete is protected before polishing. If you wait to have the floor polished then we cannot remove the stains and marking left behind from building. This can mean that there is more discolouration on the concrete that we cannot remove with our a heavier grind which will expose aggregate. By Diagrind ® ® completing the polishing first we can get a better finish on the floor as walls are not in the way but also there is less change/risk that the floor has already been contaminated and stained. As we are not removing any material from the surface if the floor is stained we cant really remove it. Once the floor is polished it is seal and is fairly resistant to some damage. It is important though the builder tries to protect the floor during the rest of the build. 

The best way to protect the floor is to keep a clean job site. Prior to walls and a roof being erected simple cleaning/sweeping or blowing debris and contaminants off the concrete. Don't leave nails and screws there to get wet and rust. Don't store timber on there to get wet and leach tannin. Once walls and a roof are installed you can protect the floor by covering. The product we use most often is RAM board but your builder has the final say. 

If your floor does get damaged during the build depending on th type of damage we can return and repair most problems. If you have any questions on a burnished finish please contact the team at Diagrind ® ® Today
