If you’re curious on how burnished concrete floors can be a game-changer for your space, read on below!
What is Burnished Concrete?
Burnished concrete is a unique flooring option that sets itself apart from traditional polished concrete through its finishing process.
While both methods aim to enhance the natural beauty of concrete, burnishing achieves this through high-speed burnishing machines that heat the floor’s surface to a sheen.
Instead of the gradual grinding that polished concrete undergoes, burnished concrete attains its smoothness and gloss in another way. This comes from the friction and heat produced by a power trowel or floor burnisher rotating at high revolutions per minute. The heat turns the concrete surface into a smooth finish that is durable and easy to maintain.
The technique results in a floor with a mirror-like finish. This achieves both aesthetic appeal and durability without the addition of a coating like wax or sealant.
Differences from Polished Concrete
Burnished concrete and polished concrete are often confused, yet they boast distinct differences, primarily in the finish and process.
Polished concrete involves multiple stages of grinding with progressively finer grades of diamond abrasives. However, burnished concrete is enhanced through a single pass of a high-speed floor burnisher that hones the surface to a high gloss.
The equipment and tools differ as well; polished concrete mandates the use of a concrete grinder and often epoxy or concrete densifier to fill in any gaps and increase the hardness of the floor.
On the other hand, a power trowel or propane-powered burnisher is used to create the smooth, reflective finish distinctive to burnished concrete without the need for additional coatings.
Pros and Cons of Burnished Concrete Floors

Durability
Burnished concrete ranks highly in resilience when it faces everyday wear and tear. The dense surface, formed through the heat and rotational action of the burnishing process, makes it resistant to moisture ingress and stains.
In commercial settings, there is always high foot traffic. Thus, the durability of a burnished concrete finish ensures longevity. It effectively stands up to the rigors of heavy use without succumbing to dust and abrasions that floor coatings like epoxy are prone to over time.
Maintenance
Maintenance for burnished concrete floors is comparatively minimal, requiring basic cleaning with a mop and occasional passing with a floor scrubber to maintain its sheen. Regular upkeep prevents the accumulation of grime and ensures the longevity of the high-gloss surface.
Using a pH-neutral cleaner helps protect the integrity of the burnished finish, warding off damage from harsh chemicals. In high-traffic areas, periodic buffing can also be employed to restore the original luster without the reapplication of sealants or wax.
How to Achieve a Burnished Concrete Finish
Moving on to crafting a burnished concrete finish, one enters a stage where precision meets practice. Here are the steps you can follow to achieve a burnished concrete finish:
Necessary supplies
The process requires a high-performance burnisher or power trowel. These machines are critical as they generate the necessary speed and heat that yield the floor’s signature gloss.
Additionally, choosing the appropriate abrasive pads is important to achieve the desired sheen on the concrete surface. The pads must be compatible with the burnisher and be suitable for the specific hardness of the concrete being worked on.
Choosing the right machine
The choice of the correct burnishing tool is crucial for achieving the desired gloss on concrete floors. It depends on factors like the concrete’s hardness, the size of the area, and the machine’s power source. Options will range from electric to propane-driven systems providing flexibility for different project needs.
