Burnished Floors

Burnished concrete is a polished concrete finish where there is no stone aggregate exposed through the floor. The quality of the finish is slab-dependent, it should be poured as level as possible, as the polishing process won't remove material from the surface. The surface should be free from imperfections, screed marks and footprints.

When pouring the concrete, the concreter should use the concrete helicopter trowel until the surface is black. The concrete is then left to cure - typically 2 weeks, but can be less if a higher MPA, although we recommend a minimum of 32MPA for a burnished finish.

It's important that the concrete is protected before its polished. If you wait to have the floor polished, such as on a slab in a new residential property, we cannot remove stains left behind from building. This means marks and discolouration that we cannot remove without using our heavier grinder, which will expose more aggregate. If the polishing is completed before building, we can achieve a better finish, as there's no walls in the way, and less risk that the concrete has been stained or contaminated. If the floor is stained, we can't really remove it, as we're not removing material from the surface.

Once the floor is polished, it is sealed and is damage resistant, although it's important the builder protects the floor during the build. We can repair damage done to the floor during the build process.
