Concrete curing time: when can you walk or drive on it?

Concrete doesn’t dry — it cures, gaining strength for weeks as long as it stays moist and warm enough. Here’s when the manufacturers say you can walk and drive on it, where the advice disagrees, and how to cure it properly.

Figures checked October 1, 2026

When can you walk on it?

It depends on the mix. From the manufacturers’ own product information:

ProductFoot traffic after
Quikrete Fast-Setting Concrete Mix4 hours
Sakrete Fast-Setting Concrete Mix6 hours
QUIKRETE 5000 Concrete Mix10–12 hours
Sakrete 5000 Plus12 hours
Sakrete High-Strength Concrete Mix24 hours

Times assume normal temperatures; cold weather slows everything down.

When can you drive on it?

Here the sources disagree. Sakrete’s product information says vehicle traffic after 72 hours for its High-Strength mix (48 hours for Fast-Setting). The Michigan Concrete Association’s driveway guidelines say 7 days — or once tests confirm the concrete has reached 2,500 psi.

For a new driveway, the longer wait costs you nothing but patience, and the slab is gaining strength the whole time. Keep heavy vehicles off longer still.

How strength builds

Concrete is specified by its strength at 28 days. Quikrete’s data sheet for its standard Concrete Mix gives about 2,500 psi at 7 days and 4,000 psi at 28 — more than half its design strength in the first week, and most of the rest over the following three.

How to cure it

Curing means keeping the concrete moist and at a reasonable temperature while it gains strength. How long:

  • NRMCA: 3–7 days of moist curing.
  • Quikrete, for its Concrete Mix: 5 days when it’s 70 °F or warmer, 7 days between 50 and 70 °F.
  • Older ACI guidance: 7 days for concrete made with ordinary (Type I) cement, 3 days for high-early (Type III).

The methods NRMCA lists for protecting fresh concrete double as curing: cover it with wet burlap or polyethylene sheeting, or spray on a liquid membrane-forming curing compound as soon as finishing is done.

Hot, dry or windy day?

The surface can crack before you’ve even finished it. Check the evaporation rate before you pour.
