Metallic Epoxy Floor Cost in Sumter, SC (2026)
Learn what metallic epoxy floor cost looks like per square foot, how prep and moisture change the price, and what to check in quotes for Metallic Epoxy Floors.
A metallic floor can make a plain garage or shop feel finished, but nobody wants to pay for swirling color and then watch it lift in a year. Knowing what drives the price is the best protection. This guide covers the metallic epoxy floor cost you can expect, why prep changes the number, and how to read a written quote. Sumter Epoxy Floors offers free on-site estimates around Sumter County, so you can compare real figures for your slab.
What Does a Metallic Floor Cost per Square Foot?
Metallic epoxy generally runs about $8 to $15 per square foot, according to Intermountain Coatings’ Epoxy Flooring Cost Per Square Foot guide (July 2025). That is higher than standard epoxy because the system uses more layers, pigment and labor to create the depth and movement.
For comparison, the same guide puts water-based epoxy at about $3 to $7 per square foot, solvent-based at $4 to $9, and 100% solids epoxy at $5 to $12. Angi (updated Aug 3, 2026) puts epoxy flooring overall at $2 to $12 per square foot installed, so metallic sits at the top of that range.
Here is what that can mean in dollars, using the $8 to $15 range from Intermountain Coatings:
- 250 sq ft (one-car garage): roughly $2,000 to $3,750
- 500 sq ft (two-car garage): roughly $4,000 to $7,500
- 750 sq ft (three-car garage): roughly $6,000 to $11,250
Those totals are simple multiplication, not quotes. Your slab, the look you want and the prep it needs will move the final figure.
Why Prep Can Change the Price More Than the Color
Metallic coatings show everything underneath. Pits, patches and uneven grinding can telegraph through a glossy finish, so the concrete needs to be right before any color goes down.
Intermountain Coatings (July 2025) lists typical add-ons:
- Basic cleaning and etching: about $1 to $2 per square foot
- Diamond grinding for damaged concrete: about $2 to $4 per square foot
- Crack repair and patching: about $3 to $5 per square foot
A clean, sound slab may need little beyond grinding. An older garage with oil stains, flaking paint or cracks will cost more up front, but skipping that work is the usual reason coatings peel. When you get a quote, ask for prep to be written out line by line so you can see what you are paying for.
Moisture and Humid Summers
Sumter has a humid subtropical climate, with average daily highs of 87.3°F in June, 90.2°F in July and 88.5°F in August (Wikipedia, Sumter, South Carolina). Concrete can hold moisture in that kind of climate, and moisture pushing up from the slab is a common cause of bubbling and lifting.
Testing is how you find out before it becomes an expensive surprise. One Stop Epoxy notes that typical epoxy coatings call for slab relative humidity of 75 percent or lower, but the coating maker’s data sheet sets the real limit for each product. One method, the ASTM F2170 in-situ relative humidity test, places probes at about 40 percent of slab depth for slabs that dry from one side. Another, the ASTM F1869 calcium chloride test, only measures the top quarter inch of the slab, so it can miss deeper moisture (Construction Canada).
If a slab reads high, a moisture-control primer or a different plan may be needed, which can add cost. It is still cheaper than redoing a floor.
How to Compare Metallic Epoxy Quotes
A low number is not always a better deal. Line up quotes on the same basis:
- Is grinding included, and is it diamond grinding rather than light etching?
- Are crack and joint repairs listed separately?
- Was moisture tested, and how?
- How many coats are in the system, including the clear topcoat?
- What is the square footage used for pricing?
Metallic floors are also a decorative choice, so ask to see color samples. You can read more about the look and the process on our Metallic Epoxy Floors page.
If a project goes over $5,000, South Carolina regulation 106-2 requires a licensed residential specialty contractor to carry a surety bond of at least $10,000 (South Carolina Code of Regulations ch. 106). Check licensing requirements with the South Carolina Department of Labor, Licensing and Regulation before you hire anyone.

Frequently Asked Questions
For about 500 square feet, the $8 to $15 per square foot range from Intermountain Coatings (July 2025) works out to roughly $4,000 to $7,500. Slab repairs, grinding and design choices can push the final price up or down, so a written quote is the only reliable number.
It depends on what you want. Standard epoxy protects the slab for less, while metallic adds depth and a one-of-a-kind finish, which suits showrooms, shops and living spaces. If appearance is not a priority, a simpler system may be the better value.
It can add a small line item, but it protects a much larger investment. Testing shows whether the slab is dry enough for the product being used, and the coating maker's data sheet sets the real limit. Ask your installer how they test and what they do if readings run high.
