Concrete may look dry on top in a few hours, but curing takes much longer. Curing is when concrete gains strength as it keeps moisture and continues to harden. If you rush this process, the concrete can end up weaker and more likely to crack. Knowing the basic timeline, along with simple dos and don’ts, can help protect your new concrete.
Concrete Curing Timeline (What to Expect)
First 24 hours:
Concrete starts to set and harden. It may feel firm, but it is still very new. During this time, keep people, pets, and heavy items off the surface.
24 to 48 hours:
The concrete is stronger, but it can still be damaged. Light foot traffic may be okay depending on the job and weather, but it is best to follow your installer’s advice.
3 to 7 days:
Concrete gains a lot of its early strength during the first week. Many slabs and driveways can handle more use during this time, but heavy loads should still be limited.
Around 28 days:
This is when concrete reaches most of its full strength. It may keep getting stronger after that, but 28 days is the common curing benchmark.
The weather also affects curing. Hot, dry weather can make concrete dry too fast. Cold weather can slow down curing. Both can affect the final strength if not handled the right way.
Dos: How to Help Concrete Cure Well
- Do keep the surface moist when needed. This helps the concrete cure evenly and gain strength.
- Do follow the timeline given by your contractor. Each project can be different.
- Do protect the area. Use barriers to keep cars, pets, and foot traffic off when needed.
- Do plan ahead. Avoid heavy use too soon, especially on driveways.
Don’ts: Common Mistakes to Avoid
- Don’t drive on it too early. Early heavy weight can cause cracks or dents.
- Don’t let it dry too fast. Fast drying can lead to surface cracks.
- Don’t ignore the weather. Heat, wind, and cold can all change curing time.
- Don’t apply coatings too soon. Some sealers or finishes need the concrete to cure first.
