A professionally installed garage floor coating in Myrtle Beach typically runs $4 to $12 per square foot, with most 2-car garages landing somewhere between $1,800 and $6,500 total. Understanding garage floor coating cost helps you budget correctly and avoid surprises. The exact number depends on the coating system you pick (epoxy is on the lower end, polyaspartic on the higher end), the size and condition of your slab, the prep work needed, and the warranty backing the install.
Below is a clear breakdown of what drives garage floor coating cost in the Grand Strand market and how to know your quote is fair.
Typical Cost Ranges by Garage Size
Most pricing is calculated by the square foot, then totaled. Here’s what national pricing data and local Grand Strand quotes typically look like for a professional install:
| Garage Size | Approximate Sq Ft | Polyaspartic Range | Epoxy Range |
|---|---|---|---|
| 1-car | 240 to 288 | $1,200 to $3,500 | $1,000 to $2,800 |
| 2-car | 400 to 576 | $2,000 to $6,900 | $1,600 to $5,800 |
| 3-car | 750 to 864 | $3,500 to $10,400 | $3,000 to $8,500 |
Larger garages usually have a lower per-square-foot price because the fixed costs (mobilization, equipment setup, dust collection) get spread over more area. A 3-car bay rarely costs three times what a 1-car costs.
Cost by Coating Type
The biggest single factor in your final garage floor coating cost is the coating system itself. Here’s the rough breakdown:
Epoxy: $4 to $10 per square foot installed. Lower up-front cost, but more likely to yellow under UV, peel from hot tire pickup, and need recoating in a Myrtle Beach climate.
Polyurea: $5 to $10 per square foot installed. Strong, fast-curing, but performance varies by formulation and installer.
Polyaspartic: $5 to $12 per square foot installed. Highest up-front cost, longest expected lifespan, UV stable, and the system best suited to coastal conditions.

7 Things That Move Your Price Up or Down
Two homes on the same street can get quotes that differ by thousands of dollars. Here’s why your garage floor coating cost varies:
1. Square footage: The single biggest variable. More slab equals more material, more grinding, and more labor.
2. Concrete condition: Hairline cracks are normal. Larger cracks, spalling, pitting, or sinking sections need repair before the coating goes down. Learn more about why concrete garage floors crack.
3. Existing coating: If your floor already has paint, sealer, or a failing epoxy on it, that has to be ground off first. Removal adds time and cost.
4. Moisture issues: Coastal South Carolina slabs often need moisture testing. If your slab transmits a high level of vapor (common in older homes near the marsh or with no vapor barrier), a moisture-mitigating primer may be required. We covered why that matters in our post on coastal humidity and garage floors.
5. Flake density and color choices: Standard flake blends are included in most quotes. Premium designs, metallic finishes, or full-broadcast flake (much heavier than a standard scatter) cost more.
6. Edges, stem walls, and stairs: Coating just the floor is one price. Adding a few inches up the wall, coating step-downs into a sunken garage, or adding adjoining stairs adds labor.
7. Access and mobilization: A standard garage on a paved driveway is straightforward. Tight access, off-grade locations, or jobs that need extra dust containment can move the number.
What’s Included in a Professional Quote
When you compare garage floor coating cost quotes from different contractors, make sure you’re comparing the same scope. A solid Myrtle Beach garage floor coating quote should include:
- On-site measurement and concrete inspection
- Moisture testing on the slab
- Full diamond grinding (not acid etching)
- Crack and pit repair with industrial repair products
- Polyaspartic base coat in your chosen color
- Vinyl flake broadcast
- Scrape and vacuum after flake cures
- Polyaspartic top coat
- Cleanup and dust collection during install
- Materials and labor warranty in writing
If a quote is missing diamond grinding, moisture testing, or a written warranty, that’s usually how the number got lower than the competition. Before signing any contract, make sure you’re asking the right questions.
Why DIY Kits Look Like a Bargain (And What They Cost You Later)
A box-store epoxy kit can run $200 to $600 and covers a 1- or 2-car garage on paper. Here’s what to know about the true garage floor coating cost of going DIY:
- The product itself is much thinner than what a pro crew installs
- Most kits use acid etching for prep, which doesn’t match the bond strength of full diamond grinding
- Without moisture testing, the coating often fails in coastal slabs within a year or two
- Removing a failed DIY coating before installing a real system adds $1 to $3 per square foot to a future job
A failed DIY job often costs more in the long run than just hiring a pro the first time.
Warranty: The Hidden Part of the Price
Two quotes at the same price are not the same job if one comes with a 1-year touch-up promise and the other comes with a written 10-year or 21-year warranty covering both materials and labor. The warranty is part of the garage floor coating cost you’re paying. Lower-priced installs almost always come with shorter or vaguer warranty terms.
The system we install at Garage Kings Myrtle Beach uses a polyaspartic base coat with a polyaspartic top coat and comes with two warranty choices:
10-Year warranty: Solid choice for most homeowners.
21-Year warranty: Most popular upgrade for owners staying long-term.
Both cover materials and labor. Both use the same coating system. The difference is in the build and length of coverage.
Average Garage Floor Coating Cost in Myrtle Beach
Most Myrtle Beach homeowners get the most value out of a polyaspartic system in the $5 to $9 per square foot range, with a 10-year or 21-year warranty in writing. This translates to:
- 1-car garage (250 sq ft): $1,250 to $2,250
- 2-car garage (500 sq ft): $2,500 to $4,500
- 3-car garage (800 sq ft): $4,000 to $7,200
These numbers assume moderate prep work, standard flake options, and a professional polyaspartic system designed for coastal conditions.
Additional Services That Add Value
While investing in your garage floor, many homeowners maximize their space with complementary upgrades:
- Basement floor coatings using the same polyaspartic system
- Concrete patio coatings to extend outdoor living areas
- Overhead garage storage installation to keep items off your new floor
- Garage cabinet installation for organized tool storage
Bundling services often reduces the overall project cost compared to doing them separately.
