How long does it take concrete to dry?

Answer 1

If you are doing something like fence post, figure around 24hrs to be able to work with it.

If its something like a flat surface (walkway etc..) figure 2 days before you can walk on it.

Answer 2

Concrete gets progressively harder over time its called curing. However it depends on several thing like temperature and moisture. You can typically walk on concrete the next day but it can be prone to scratching. I generally have my customers wait two days to walk on it and 7-10 days to drive. In summer time on hot days concrete can cure to fast and crack within hours. We use sealer and special curing compounds to retain the moisture in the concrete. We can also use retardant in the mix and cover the concrete with white plastic if it gets to hot. In cold weather in temperatures below freezing the water in the concrete mix can freeze and the mix won't be able to bind together. So we add accelerants and cover the concrete with insulation blankets to keep it from freezing. Submitted by B&B Concrete Vancouver, Wa.
