Polishing Concrete vs. Sealing: Which is Better?

Are you debating whether to polish or seal your concrete floors? Both options have their benefits, but determining which one is better for your specific needs can be a tough decision. In this article, we will explore the differences between polishing and sealing concrete, as well as the advantages and disadvantages of each. Whether you are looking for a glossy finish or added protection, understanding the nuances of these two methods will help you make an informed choice for your concrete surfaces.

Polishing Concrete

What is concrete polishing?

Concrete polishing is a process that involves grinding and polishing the surface of a concrete floor to achieve a smooth and glossy finish. This is typically done using specialized equipment and diamond abrasives to remove imperfections and create a polished surface.

Benefits of polishing concrete

  • Durability: Polished concrete floors are extremely durable and resistant to wear and tear, making them ideal for high-traffic areas.
  • Low maintenance: Polished concrete floors are easy to clean and maintain, requiring only occasional dust mopping or damp mopping to keep them looking great.
  • Aesthetic appeal: Polished concrete floors have a sleek and modern look that can enhance the overall aesthetic of a space.
  • Cost-effective: Polishing concrete is a cost-effective flooring option compared to other materials like tile or hardwood.

Process of polishing concrete

  1. Grinding: The first step in the concrete polishing process is to grind the surface of the concrete using coarse diamond abrasives to remove any existing coatings or imperfections.
  2. Honing: After grinding, finer diamond abrasives are used to smooth out the surface of the concrete and prepare it for polishing.
  3. Polishing: The final step involves polishing the concrete using progressively finer diamond abrasives to achieve a glossy finish. A densifier is often applied to help strengthen and protect the surface.

Overall, polishing concrete is a great option for creating durable, low-maintenance, and visually appealing floors in both residential and commercial spaces.

Sealing Concrete

What is concrete sealing?

Concrete sealing is the process of applying a protective layer on top of a concrete surface to prevent moisture, stains, and damage. This sealant acts as a barrier, making the concrete more resistant to wear and tear.

Benefits of sealing concrete

  • Protects against stains: Sealing concrete helps to repel oil, grease, and other stains that can easily penetrate the surface.
  • Prevents moisture damage: By sealing concrete, you can prevent water from seeping into the pores of the material, which can lead to cracking and deterioration.
  • Enhances durability: The sealant creates a protective layer that increases the lifespan of the concrete, making it more resistant to abrasion and weathering.
  • Improves appearance: Sealing concrete can enhance the color and texture of the surface, giving it a polished and professional look.

Types of concrete sealers

  1. Penetrating sealers: These sealers penetrate the surface of the concrete to form a protective barrier within the pores, making the concrete more resistant to moisture and stains.

  2. Acrylic sealers: These sealers form a clear film on top of the concrete, providing a glossy finish and protection against UV rays and chemicals.

  3. Polyurethane sealers: These sealers are more durable and long-lasting, providing a high level of protection against abrasion and wear.

Overall, sealing concrete is a crucial step in maintaining the integrity and appearance of your concrete surfaces. Choose the right type of sealer based on your specific needs and the level of protection required.


When it comes to enhancing the look and longevity of concrete surfaces, both polishing and sealing are popular options. Each method offers its own set of benefits, making it important to consider your specific needs and preferences before making a decision.


Polished concrete is known for its exceptional durability. By grinding down the surface and applying a sealant, the concrete becomes more resistant to stains, scratches, and wear and tear. This makes it a great option for high-traffic areas such as driveways, garages, and commercial spaces.

On the other hand, sealing concrete involves applying a protective layer on top of the surface to prevent moisture and chemicals from penetrating. While sealing can help improve the durability of concrete, it may not be as long-lasting as polishing. However, sealing is still a cost-effective way to protect and prolong the lifespan of your concrete surfaces.


One of the main reasons why people choose to polish concrete is its sleek and glossy appearance. Polished concrete can mimic the look of natural stone or terrazzo, giving your space a modern and sophisticated feel. Additionally, polishing can enhance the natural colors and patterns of the concrete, creating a unique and visually appealing surface.

Sealing, on the other hand, may not have as dramatic of an impact on the appearance of concrete. While sealing can help protect the surface and enhance its color, it may not provide the same level of shine and luster as polishing. However, sealing is still a great way to maintain the aesthetic appeal of your concrete surfaces.


In terms of maintenance, polished concrete is relatively low maintenance compared to sealed concrete. Polished surfaces are easy to clean and maintain, requiring only regular sweeping and occasional mopping to keep them looking their best. Additionally, polished concrete is resistant to stains and spills, making it a great option for busy households and commercial spaces.

Sealed concrete, on the other hand, may require more frequent maintenance to keep it looking its best. While sealing can help protect the surface from damage, it may need to be reapplied every few years to maintain its effectiveness. However, with proper care and maintenance, sealed concrete can still provide lasting protection and beauty to your surfaces.

In conclusion, both polishing and sealing offer unique benefits for enhancing the durability, appearance, and maintenance of concrete surfaces. Ultimately, the best option for you will depend on your specific needs and preferences. Consider the level of traffic, desired aesthetic, and maintenance requirements of your space to determine whether polishing or sealing is the better choice for you.

In conclusion, both polishing concrete and sealing have their own advantages and can be beneficial depending on the specific needs of the project. Polishing concrete can enhance the overall aesthetic appeal and increase durability, while sealing can provide added protection against stains and moisture. Ultimately, the best option will depend on factors such as budget, desired finish, and maintenance requirements. Consulting with a professional contractor can help determine the most suitable solution for achieving the desired results.
