Day one
Masking and dust containment, then diamond grinding the full slab to profile. Cracks are chased and filled, spalls rebuilt, the floor vacuumed and tack-wiped. The pigmented base coat goes down and flake is broadcast into it while it is still wet, thrown to full rejection. The floor is left to cure overnight.
Day two
The cured floor is scraped to knock down loose chip edges and vacuumed thoroughly. Two coats of UV-stable polyaspartic follow, with an hour or two between them because polyaspartic recoats in hours rather than overnight. That is the whole reason both topcoats land in a single day.
The cure schedule is not negotiable
Walk on it at 24 hours, park on it at 72. Those numbers are chemistry, not scheduling preference. Parking early is the fastest way to print a permanent tire pattern into a floor that has not finished cross-linking, and that damage is use rather than a defect, so it is not a warranty item.
When one day makes sense
A full polyaspartic build gets the space back the same evening and drivable in 24 hours, for about $2-$3 per square foot more. If the garage is the only parking, if it is winter and the slab is too cold for epoxy to cure, or if a business cannot close, that premium is worth paying. Otherwise the two-day epoxy-base build gives more film thickness for less money.
