Polished Concrete

Commercial & Residential Polished Concrete Floors In Maryland

Concrete Polishing and Staining

Concrete flooring was once primarily used in industrial spaces, but today it has become a popular choice for commercial and residential properties throughout Columbia, MD and Ellicott City, MD. It is commonly found in retail stores, airports, churches, malls, and modern home designs due to its strength, durability, and low maintenance requirements. Concrete floors are also highly resistant to heavy foot traffic and equipment use, making them a practical and long-lasting flooring solution.


Polished concrete is a multi-step finishing process that allows for a range of sheen levels, from satin to high-gloss finishes. When properly executed, polished concrete can achieve a reflective surface that resembles marble or granite, especially when combined with decorative staining. For a terrazzo-style appearance, the surface can be ground to expose the natural aggregate within the concrete, creating a unique and decorative finish.


At FloorGem, we specialize in polished concrete installation, staining, restoration, and maintenance. Our team uses professional-grade equipment with progressively finer diamond abrasives to achieve a smooth, durable, and visually appealing finish. We carefully monitor each stage of the polishing process to ensure the proper grit progression and the highest quality results for every project in Columbia and Ellicott City, MD.

We offer the following grades of finish for your floor:

  • Grade 1 - Light Sand: This is a ground and polished surface generally exposing only the sand particles in the floor. It's considered a creamy looking surface and is a very popular choice for both architectural ground and polished flooring.
  • Grade 2 - Salt & Pepper Finish: This is a ground and polished surface that typically exposes a small amount of aggregate in the floor. This finish is normally chosen to give the appearance of an aged surface.
  • Grade 3: Aggregate Finish: This is a deeper cut surface generally exposing the largest amount of aggregate in the floor. It's typically chosen when the concrete has been seeded with custom aggregate chips.
