The short answer
How long concrete takes to cure
New concrete takes foot traffic after one to two days, takes cars after about seven, and reaches full strength in about 28 days.
Curing is the slab gaining strength, not just drying, so a surface that looks dry by evening is still weak underneath. Prep and pour take a few days before that clock starts. Counted from the day we pour, it runs like this:
- 1–2 days Walk on it Feet only, nothing heavy rolled or dragged across it.
- About 7 days Drive on it Cars and pickups back on the driveway.
- About 28 days Full strength The slab is fully cured and carries what it was built for.
