How Long After a Sidewalk is Poured Can You Walk on It?

A new concrete sidewalk begins to set within a few hours after but you must wait 24 to 48 hours before walking on it. During this time, concrete is still wet under the surface, and twisting or scuffing your feet on it can leave a permanent mark.
The surface of your concrete structure might look dry after only 12 hours, but still keep your pets, strollers, skateboards, and bicycles—everything—away from the concrete.

Complete Duration of Concrete Curing
It takes around 28 days for your concrete structure to completely cure. However, your concrete becomes able to support the weight much sooner. For residential sidewalks where the foot traffic is less, you can use the sidewalk within 24 hours but for commercial areas, limit access for 48 hours. It will allow the concrete to properly cure and gain strength. If you notice damage after the sidewalk has been used, consider sidewalk repair services for professional solutions.

Difference Between Concrete Curing and Drying
Concrete curing and drying are two different processes that might occur simultaneously after pouring and smoothing out the concrete. During the drying process, the excess water from freshly poured concrete evaporates, and it becomes durable enough to walk on. However, curing concrete is a chemical process that allows the concrete to hydrate and attain its desired strength. If not cured properly, issues such as cracks may arise, necessitating concrete sidewalk repair.

Factors that Impact Concrete Curing Time
Thickness of concrete, weather conditions, and concrete mix design can all have a great impact on its curing time. The best temperature for concrete to cure is between 50°F and 80°F. Temperatures colder than that slow down the curing process. During freezing weather, wet concrete can freeze and expand, leading to crack formation, which may require concrete crack repair. Similarly, in warm weather, the concrete dries up too quickly, leading to shrinkage cracks.

Another important factor that can affect the curing time is the water-cement ratio of the concrete mix. More water in the mix can adversely impact the concrete's strength and durability. It also increases the curing and drying time of the surface as well.
The ideal thickness of a concrete sidewalk is 4 inches. A surface thicker than that might take more time to dry. It is the reason why if the concrete layer is thick, the work must be done during the mild temperature so that it gets proper time to cure.

Is It Wise to Speed Up the Curing Process?
You can speed up the curing process, but it's not recommended. Proper curing time is essential for the strength development of concrete. If you take measures to make the concrete dry up quickly, it might become weak, which could necessitate sidewalk replacement.

However, if you live in a place with colder weather conditions and you have no other option but to speed up the curing process, you can opt for several ways. One efficient way is to add hot water to the mix and use a non-chloride accelerator.

Conclusion
You would not want to spend time and money repairing or replacing sidewalks damaged during the curing time. Therefore, it is a wise option to give your sidewalk 24 to 48 hours before using it.
However, make sure not to put any heavy weight on the concrete for a week. It will allow the concrete walkway to become strong and support the weight of pedestrians for years to come.
