The term polished concrete floors is thrown around a lot these days, but the truth is, not every slab of concrete can (or should) be polished.
In many cases, polished concrete flooring is used to describe anything from a plain slab with a clear coating to a fully honed surface with exposed aggregate. But the final result depends on more than just looks. Preparation, finish type, and the installation process all play a major role in how the floor performs and how long it lasts.
At Ascoat, we bring over 30 years of experience in commercial concrete flooring to every project. Whether you’re aiming for a subtle matte finish or a high-gloss architectural surface, we help you strike the right balance between durability, practicality, and design.
Where Polished Concrete Flooring Works Best
Polished cement floors have become a stylish and practical choice for a wide range of environments, including:
- Retail outlets
- Showrooms
- Restaurants and cafes
- Corporate offices
- Residential homes
Their versatility, durability, and low maintenance make polished concrete floors a popular option across commercial and residential spaces alike.
Understanding the Levels of Finish
There are three common levels of polished concrete flooring, each offering a distinct look and performance profile. These can be sealed with epoxy or polyurethane coatings for gloss or matte finishes, or treated with penetrating sealers for a more natural appearance.
1. Minimal / Salt and Pepper Exposure
This finish involves lightly polishing the surface without exposing aggregate. It delivers a clean, minimalist look, but it’s difficult to achieve because it relies on a perfectly flat pour, which isn’t always realistic on most projects.
2. Light Random Exposure
Currently the most popular choice, this finish shows varied aggregate exposure, giving the floor depth and natural character without appearing too “busy.”
3. Full Aggregate Exposure
For a terrazzo-like appearance, this option grinds deeper into the slab to reveal full aggregate exposure. It creates a bold, uniform look ideal for feature spaces or high-end commercial concrete flooring applications.
New Projects: Planning Ahead for Polished Concrete Floors
For new builds, planning early makes all the difference. To achieve the best polished cement floors, careful attention must be given to:
- Concrete colour and mix design
- Aggregate type and consistency
- Control and expansion joint placement
- Finishing quality during the pour
Our experienced team works closely with builders, architects, and project managers to ensure the concrete is designed for the specific polishing outcome you want, reducing surprises once grinding begins.
Renovations: What to Expect with Existing Slabs
When polishing existing concrete, it’s important to understand that imperfections and repairs will always be visible. Expect natural variation such as:
- Different slab batches or repairs
- Cracks, patching, and infills
- Discolouration or uneven textures
While some see this as a drawback, many clients appreciate the unique, rustic aesthetic that these variations create—adding authentic industrial character to the space.
When Polished Concrete Isn’t the Right Fit
Because polished concrete floors depend on the slab’s existing quality, they’re not always suitable when a perfectly uniform appearance is required. In these cases, we often recommend alternative solutions such as:
- Hybrid stone systems
- Flake flooring systems
- High-performance epoxy or resin coatings
These options deliver consistent finishes and durability while maintaining the sleek look of polished cement floors, making them ideal for environments where control and performance are key.
How Much Do Polished Concrete Floors Cost?
The cost of polished concrete floors can vary depending on factors such as:
- Desired aggregate exposure level
- Size and condition of the floor
- Chosen finish (matte, satin, or high gloss)
- Number of grinding and sealing steps
At Ascoat, we provide transparent pricing for every project, balancing your design goals with long-term performance and maintenance considerations. Investing in quality workmanship up front means lower upkeep costs and better results over time.
