Most 2-car garages (about 400 sq ft) cost $400–$1,000 DIY, $1,200–$3,200 professionally installed epoxy, or $2,000–$4,800 for polyaspartic. Your exact quote depends on floor condition, prep work, and where you live.
Compare all coatings for your garage
Same floor, different coating — here is what each option costs at your size:
| Coating | Rate / sq ft | Your total |
|---|---|---|
| DIY epoxy kit | $1.00–$2.50 | |
| Pro epoxy, solid color | $3–$5 | |
| Pro epoxy flake system | $5–$8 | |
| Pro polyaspartic | $5–$12 |
What affects the price?
- Size: the bigger the floor, the lower the per-square-foot rate — fixed costs spread further.
- Coating type: a basic DIY kit is cheapest; a flake system or polyaspartic costs more but lasts much longer.
- Floor condition: cracks, spalling, old coatings, and moisture problems add $0.50–$3.00 per sq ft for repair and prep.
- Location: labor rates vary by city and state — always get 2–3 local quotes before deciding.
Frequently asked questions
How much does epoxy cost for a 2-car garage?
A 400 sq ft 2-car garage costs about $400–$1,000 for a DIY kit, $1,200–$3,200 for professionally installed epoxy, and $2,000–$4,800 for polyaspartic in 2026.
Should I DIY or hire a pro?
DIY saves 60–80% upfront, but the coating usually lasts 2–5 years and fails more often without proper prep (diamond grinding). A pro job lasts 10–15+ years. If the floor has cracks or moisture issues, hire a pro.
How long does an epoxy garage floor last?
A DIY kit lasts about 2–5 years, professional epoxy about 10–15 years, and polyaspartic about 15–20+ years — and polyaspartic will not yellow in sunlight.
