Polished concrete typically costs $3–$12 per square foot for standard finishes, based on HomeGuide’s 2026 national figures: $3–$8 for a cream finish, $4–$10 for salt-and-pepper, and $6–$12 for exposed aggregate. Small floors under 1,000 square feet often run $8–$15+. Polishing grinds and hardens the slab itself rather than coating it, so there is no coating to peel; a coating such as epoxy sits on top instead.

Cost by finish
The deeper the grind, the more aggregate shows and the more it costs.
| Finish | What you see | Installed cost per sq ft |
|---|---|---|
| Cream | Smooth surface, minimal aggregate | $3–$8 |
| Salt and pepper | Fine speckled aggregate | $4–$10 |
| Exposed aggregate (rock cut) | Large stones, terrazzo-like | $6–$12 |
Cost by gloss level
| Gloss | Look | Installed cost per sq ft |
|---|---|---|
| Matte | Flat, natural concrete | $3–$6 |
| Low sheen | Subtle luster | $4–$8 |
| Medium gloss | Noticeable shine | $5–$10 |
| High gloss | Mirror-like | $6–$15 |
Size matters: floors under 1,000 square feet often price at $8–$15+, while floors over 5,000 square feet can drop to $3–$6.
Prep and condition of the slab
Polishing shows the slab as it is, so existing damage matters:
- Uneven floors may need leveling, about $3–$12 per square foot.
- Minor crack and patch repairs run about $100–$800.
- Old sealers, paint or epoxy have to be stripped first.
- Tight layouts, many corners and basements with limited access cost more; HomeGuide notes hard-to-reach areas can cost 10% to 30% more.
Homes vs. shops and warehouses
- Homes: cream or salt-and-pepper finishes at low to medium gloss are common in living areas and basements.
- Shops, warehouses and showrooms: polished concrete stands up to traffic and is easy to clean. Large areas bring the price per square foot down. See commercial concrete.
Staining and dyeing add-ons
Color can be added during polishing. Dye adds about $1–$3 per square foot for vibrant, even color; staining runs about $3–$5 per square foot for one color. Logos and custom graphics cost $300–$2,000+. See concrete staining.
Upkeep
True polished concrete doesn’t require a sealer, because the densifier hardens the surface. A stain-guard sealer is still a good idea in kitchens, garages and busy areas; sealing costs about $1–$3 per square foot and is reapplied every two to five years. It isn’t completely stain-proof; acids and harsh chemicals can etch it.
Garage floor? A garage floor coating adds chemical and hot-tire resistance; polishing keeps bare concrete.

Polished concrete questions
Is polished concrete slippery?
Properly finished polished concrete meets OSHA and ADA slip-resistance standards when dry, according to HomeGuide. Like tile or hardwood, it becomes slippery when wet, so lower gloss levels or mats near entrances help.
Can an old garage floor be polished?
Often, if the slab is sound. Old coatings must be stripped, cracks repaired and uneven areas leveled first, which adds cost. Heavy oil staining may still show through after polishing.
Does polished concrete need to be sealed?
Not strictly, because the densifier hardens the surface. A stain-guard sealer helps in kitchens, garages and high-traffic areas and is reapplied every two to five years.
