- Prep Work: 30–50% of total labor time, including:
- Pressure washing (0.50–0.50–1.00/sq. ft.).
- Acid etching (0.75–0.75–1.50/sq. ft.).
- Crack filling (1–1–3/sq. ft.).
- Application: 1.50–1.50–3.50/sq. ft. for rolling or spraying epoxy.
D. Geographic Location
- High-Cost Areas (e.g., NYC, SF): 6–6–15/sq. ft. due to labor and material markups.
- Midwest/South (e.g., TX, OH): 3–3–8/sq. ft.
3. Professional Installation: Step-by-Step Cost Breakdown
A. Materials (1.50–1.50–8.00/sq. ft.)
- Primer: Bonds epoxy to concrete (0.50–0.50–1.50/sq. ft.).
- Base Coat: Provides color and thickness (1.00–1.00–3.00/sq. ft.).
- Top Coat: Enhances durability; options include:
- Polyurethane: UV-resistant (1–1–3/sq. ft.).
- Polyaspartic: Fast-curing (2–2–4/sq. ft.).
B. Labor (2.00–2.00–5.00/sq. ft.)
- Prep Work: 1–2 days for cleaning, etching, and repairs.
- Application: 1–3 days for coating and curing.
C. Additional Fees
- Moving Belongings: 100–100–300 to clear the garage.

4. DIY vs. Professional Installation
A. DIY Epoxy Kits
- Pros:
- Lower upfront cost (e.g., Rust-Oleum RockSolid: 120–120–200 for 250 sq. ft.).
- Flexibility to work at your own pace.
- Cons:
- Short Lifespan: DIY kits last 2–5 years vs. 10+ years for professional jobs.
- Labor-Intensive: Requires 20–30 hours of work.
Steps for DIY Success:
- Clean Thoroughly: Use a degreaser like Simple Green to remove oil stains.
- Etch Concrete: Apply muriatic acid (follow OSHA safety guidelines).
- Apply Epoxy: Use a notched squeegee for even coverage.
B. Professional Services
- Pros:
- Warranties: Companies like EpoxyMaster offer 10–20-year warranties.
- Quality Finish: Industrial-grade materials resist chipping and UV damage.
- Cons:
- Scheduling Delays: High-demand contractors may book months in advance.
5. Geographic Cost Variations
