Here are some of the common questions we hear about polished concrete floors.

What is concrete polishing?

Kansas City Concrete polishing is NOT like polishing other floors. You are not just applying a surface polish or coating to a concrete slab.

It’s similar to polishing granite or marble. Specialized equipment using diamond grit, is used to finely grind the surface of the floor. Concrete polishers use different grit levels to achieve different looks in the finished product.

The resulting glossiness comes from the concrete itself – not from adding a shiny liquid coating.

Concrete polishing not only makes your floor look great but also makes it more durable. By increasing the density of the concrete’s molecules, the hardness of your floor nearly doubles during this process.

Do they have a dedicated concrete polishing team? Or do they have “a guy who can do that”?

Do they have a continuing education program?  To keep their technicians informed and trained on the latest materials, tools, and techniques.

Do they have a high employee turnover rate? It’s hard for a concrete polishing service provider to build a team of experts when they have to constantly hire and train new employees.
