Understanding the Difference Between Polished Concrete and Grind and Sealed Concrete

Polished Concrete and Grind and Sealed Concrete: Which is Best for Your Space?

Concrete flooring has become a popular choice for both commercial and residential properties due to its durability, aesthetic appeal, and versatility. If you’re considering concrete floors, you might be wondering about the difference between polished concrete and grind and sealed concrete. While these two options can look similar, they involve different processes and have distinct characteristics. Here’s a guide to help you understand the key differences and decide which is best for your project.

Polished Concrete Floors

Polished concrete is created through a mechanical process of grinding and polishing the surface of an existing concrete slab. This is done using engineered floor grinders fitted with industrial diamonds. The process involves several stages of grinding with progressively finer grits of diamond abrasives until the desired level of shine is achieved, ranging from a matte finish to a high-gloss, glass-like finish.

Levels of Polished Concrete Finish:

1. Level 1 – Soft Matte Finish: This finish has a matte look with minimal reflection, giving the floor a soft, hazy appearance.
2. Level 2 – Low Sheen Finish: This finish has a slight sheen and can reflect overhead light faintly from a distance of about 100 feet.
3. Level 3 – Medium Gloss Finish: With a medium gloss, this finish clearly reflects objects and is popular in areas like restaurants and retail spaces.
4. Level 4 – High Gloss Finish: This highly reflective finish gives a wet appearance and offers the highest level of shine, similar to glass.

Grind and Sealed Concrete Floors

Grind and sealed concrete involves grinding the concrete surface to remove contaminants and then sealing it with a topical sealer. The process includes patching any cracks or divots, cleaning the surface, and applying the sealer. This method can also include adding color stains for a customized look.

Steps for Grind and Sealed Concrete:

1. Grinding: The concrete is ground to remove any surface imperfections.
2. Patching: Cracks and divots are patched as necessary.
3. Optional Additional Grinding: If required, the concrete may be ground again with finer abrasives.
4. Cleaning: The surface is thoroughly cleaned.
5. Sealing: A topical sealer is applied to protect the surface. Multiple coats may be needed for softer or more porous concrete.

Key Differences Between Polished and Grind and Sealed Concrete

1. Appearance:

Polished concrete achieves its finish through a multi-step mechanical process that enhances the natural beauty of the concrete.

Grind and sealed concrete gets its finish from the topical sealer, which can provide a more consistent appearance across different floors.

1. Durability:

Polished concrete is highly durable and resistant to scratches and stains, making it suitable for high-traffic areas. It requires minimal maintenance and can last for decades with proper care.

Grind and sealed concrete offers good protection against stains and spills but may require re-sealing periodically, especially in high-traffic areas.

1. Cost:

Polished concrete is generally more labor-intensive and expensive due to the detailed process involved.

Grind and sealed concrete is a more cost-effective option, suitable for those seeking the look of polished concrete at a lower price point.

Choosing the Right Concrete Flooring

When deciding between polished concrete and grind and sealed concrete, consider the specific needs of your space, the level of traffic, and your budget. Both options provide a durable and attractive flooring solution, but they differ in terms of maintenance, longevity, and initial cost.
