Quick answer
A standard 2-car garage takes 2–3 days with an epoxy system, or a single working day with polyaspartic. You can walk on an epoxy floor about 24 hours after the final coat and park on it after 72; a polyaspartic floor is walkable the same evening and takes vehicles in roughly 24 hours.
Timeline drives more decisions than price does — especially if the garage is where two cars live. Here's the real schedule for each system, and what actually causes a job to run long.
| System | On site → back in service |
|---|---|
| Full polyaspartic (1-day) | 1 day · drive in ≈24 hrs |
| Epoxy base + polyaspartic topcoat | 2 days · drive in ≈48 hrs |
| Full epoxy + urethane topcoat | 2–3 days · drive in 72 hrs |
| Commercial retail floor | Fri close → Mon open |

What affects the price
- Day one is always prep: diamond grinding, crack routing, spall repair, moisture testing
- Epoxy needs 12–24 hours between coats; polyaspartic needs 1–2, which is the whole difference
- Cure ≠ dry: walkable in 24 hours, drivable in 72 for a standard epoxy build
- What causes overruns: unexpected crack and spall repair, old coatings, high moisture readings
- Commercial floors are phased or done over a weekend, so the space rarely loses a trading day
