When choosing a flooring solution for a commercial facility, concrete is one of the most practical and cost-effective options. But here’s a question we hear often from general contractors and facility managers: “What’s the difference between polished concrete and sealed concrete and which is right for my project?”

At Bungay Flooring Systems, we specialize in both. The choice depends on your facility’s needs, budget, and long-term goals. Let’s break down the differences.

1. The "Concrete" Process

Polished Concrete

Achieved through a mechanical grinding and polishing process using diamond tooling.
The surface is densified, hardened, and refined through multiple grinding stages.
Results in a smooth, glossy finish that’s highly durable and reflective.

Sealed Concrete

Involves applying a topical sealer (acrylic, epoxy, or urethane) to the surface of the slab.
Creates a protective layer on top of the concrete.
Less labor-intensive and faster to apply, but not as durable long term.

2. Durability & Performance

Polished Concrete:

Extremely durable; holds up under heavy forklift traffic, carts, and machinery.
The surface is part of the slab itself, so it won’t peel or delaminate.
Long lifespan when properly maintained (10+ years).

Sealed Concrete:

More vulnerable to wear, scratching, and chemical exposure.
Sealers can wear down over time, requiring reapplication.
Best suited for light- to medium-duty facilities, not heavy industrial use.

3. Maintenance

Polished Concrete:

Requires only routine sweeping and occasional auto-scrubbing.
No waxing, stripping, or resealing needed.
Over its lifecycle, maintenance costs are 30 - 50% lower than sealed surfaces.

Sealed Concrete:

Needs periodic resealing (every 1- 3 years, depending on use).
Sensitive to moisture, hot tire pickup, and harsh chemicals.
Higher long-term maintenance and replacement costs.

4. Aesthetics & Customization

Polished Concrete:

Can achieve a high-gloss, satin, or matte finish.
Decorative options include dye, scoring, or patterns for a professional look.
Enhances light reflectivity - can even reduce energy costs in large spaces.

Sealed Concrete:

Typically has a uniform, coated look.
Decorative sealers can add color or gloss, but tend to show wear more quickly.
Less flexibility compared to polished systems.

5. Cost & ROI

Upfront Cost: Sealed concrete is generally cheaper at installation because the process is quicker.
Long-Term ROI: Polished concrete often provides better value over 10+ years because it lasts longer and requires less maintenance.

For example:

A sealed surface may cost less upfront, but if it requires resealing every 2 years, expenses quickly add up.
A polished surface has a higher initial investment but can remain in top condition with minimal maintenance for a decade or more.

Which One Should You Choose?

Choose Polished Concrete if:
- Your facility experiences heavy forklift traffic or constant use.
- You want a long-lasting, low-maintenance solution.
- You manage warehouses, healthcare spaces, schools, or auto dealerships.
Choose Sealed Concrete if:
- You need a quick, budget-friendly option.
- Your facility has light to moderate use and minimal chemical exposure.
- The floor isn’t central to operations (storage rooms, small offices, etc.).
