What is Polished Concrete:
Polished concrete provides a durable, cost-effective, and easy to maintain floor that uses the existing concrete in your space. Your concrete will be processed through a series of mechanical grinding and polishing steps, to refine the surface to a shine. This process uses a penetrant chemical known as a hardener, which creates a chemical reaction to help harden and dust proof the surface. Many shine levels can be achieved, depending upon budget and desired effect.
Benefits of Polished Concrete
- Long life cycle. When properly cared for, polished concrete floors can last indefinitely.
- Eliminate waxing, peeling of coatings, nasty chemicals for stripping and reapplying.
- Strong enough to handle forklift, heavy machinery, and constant foot traffic.
- The high light reflectivity of polished concrete not only provides a beautiful aesthetic but can help reduce electric bills by reducing the amount of overhead lighting required.
- Polished concrete may be dyed, patterned or engraved to add a custom look.
Initial grinding steps typically involve metal bonded diamond tools to remove the top layer of concrete, open the surface and prepare the slab for subsequent steps. The desired level of aggregate exposure and the flatness of the floor determine a starting grit, typically 30. After the initial cut, finer diamond tools are used to remove the scratches from the previous grits, 70 grit, then 120 grit.
For soft floors, a densifier may be applied after processing the metal diamond tools. This helps to get a harder finish, assists in properly refining the concrete and makes the transition tools last longer.
After metal tools, hone the concrete using hybrid transitional tooling to smooth the floor and remove any residual metal scratches remaining in the concrete. For typical projects, we utilize 100 grit “Calibra” ceramic tooling. Higher or lower grits can be used depending on the floor.
Follow the transition tooling with 220, then 400 grit resin bonded diamond tools. These tools are attached to the grinder with Velcro pads. HGR uses both conventional and V-HARR diamond tools for this application. Leaving the floor at 400 grit will result in a matte finish. Depending on the desired sheen level, you may continue with higher grits. 800 grit will produce a moderate sheen, 1800 will produce a high sheen, 3000 will produce an almost mirror-like finish.
A final guard or “sealer” product may be added to increase stain resistance. A guard is required when applying dyes to the floor.
