When it comes to durable and beautiful concrete floors, you may have questions. What is the difference between a polished floor and a sealed floor? Which type of floor finishing is the best choice for your business or home and fulfills your needs? Which application do floor specialists recommend?
ACT Restoration’s concrete flooring experts are here to help with answers!
Concrete floors are a great addition to any space, but deciding which finishing process to use can be challenging. Polished concrete and grind and seal concrete floors both look great and are economical flooring solutions for many types of spaces. But what’s the difference between polished concrete and grind and seal concrete floors?
Let us walk you through the differences between these two concrete floor finishing options.
What Is Polished Concrete?
Polished concrete is a popular choice for commercial and residential buildings because it’s a renewable resource and green flooring finishing. Floor polishing can be an inexpensive alternative for many business owners and homeowners because it utilizes a floor surface that already exists – in many cases, as a subfloor. Using floor staining or floor dye can create a visually stunning variegated look for your floors.
Floor polishing creates a surface that’s low maintenance as well. Polished concrete is easy to clean and doesn’t require stripping or waxing like other floors. Floor polishing specialists agree it’s an excellent choice for allergy sufferers because it doesn’t accumulate dust like other types of flooring, and it resists mold and dust mites.
Polished concrete floors can be left the original gray color or can be colored by floor dying or concrete floor staining. Many exciting looks can be achieved with floor staining and can be used to imitate natural stone, such as marble.
What Happens During Concrete Polishing?
Polished concrete is a mechanical process of honing and polishing the surface of an existing slab of concrete. Technicians use engineered floor grinders fitted with industrial diamond abrasives.
The entire process involves grinding, honing, and polishing the floor using finer grits of diamond abrasives until the floor reaches your desired level of shine. Polished concrete is more labor-intensive than grind and seal concrete floors.
4 Levels of Shine for Polished Concrete
You can choose from four levels of shine for your polished concrete floor.
● Level 1: Soft Matte Finish polished concrete has a soft finish with minimal reflection.
● Level 2: Low Sheen Finish has a low-luster sheen that is the most popular with our customers.
● Level 3: Medium Gloss Finish clearly reflects objects and is popular in restaurants, breweries, and retail.
● Level 4: High Gloss Finish is the highest level of shine and reflects the most light. It can appear wet from some vantage points.
What Is Sealed Concrete?
If you desire a highly glossy finish for your concrete floor that effectively repels oil and other liquids, choose sealed concrete. It involves grinding down the floor and sealing with a topical sealer, and the result is similar to that of polished concrete.
Sealed concrete is highly effective in high-moisture commercial areas, such as restaurants or breweries. Grind and seal concrete floors are also sometimes cheaper than polished concrete, as well as very durable and low-maintenance.
Our floor specialists at ACT Restoration recommend sealed concrete to business and residential customers alike, because it is a perfect choice for areas of high moisture. Its highly polished surface also resists heavy foot traffic and retains its brilliant shine.
What’s the Process to Grind and Seal Concrete Floors?
The surface of a sealed concrete floor is ground using special equipment as in floor polishing, but the concrete floor resurfacing process goes one step further by applying a sealant to the surface, thus sealing the concrete.
Grind and seal concrete floors have a specific order of steps, which involves grinding the floor, patching cracks, cleaning, and, if chosen, a particular color stain is applied. Last, a topical sealer is applied to the floor to protect it.
More porous floors may require additional layers of sealer to help prevent the floor from absorbing water.
What’s the Difference Between Polished vs Grind and Seal?
Though both methods produce similar results, they have several significant differences. Call us with any questions you may have about concrete floor restoration!

Here are some differences between polished concrete and grind and seal.
The benefit of either floor finish type is a glossy concrete floor. Both polished concrete and grind and seal produce different levels of shine that are almost indistinguishable. The main difference is that polished concrete achieves the look through many levels of diamond grinding, while grind and seal are finished with a sealer.
In addition, grind and seal concrete floors are more consistent from room to room. The applied sealer is consistent and does not rely on the concrete’s original look, which helps create a seamless look between your home or business rooms. Polished concrete will maintain its original appearance even through the grinding steps.
The chosen method for your floors will depend on the type of traffic and wear-and-tear your floor will experience. You should work with your contractor to determine the durability your floor needs.
Polished concrete is the way to go if your space is prone to scratches. The polishing method helps protect the floor from incidental damage and can last a very long time when maintained properly. Grind and seal floors are at a disadvantage in high-traffic areas and may need to be resealed more frequently, which can be costly in larger spaces.
However, if your space is prone to stains, oil, grease, or animal urine, grind and seal is the best choice. The grind and seal method uses a chemical-resistant polyurethane sealer, preventing liquids from penetrating the floor. Grind and seal is recommended for bathrooms, garages, or basement floors.
Cost is a factor when choosing between grind and seal or polished concrete. Grind and seal floors are cheaper in most cases than polished concrete, due to polished concrete’s labor-intensive process. However, the cost will vary depending on the traffic and use of your floor.
