Follow the cure time information on the manufacturer’s label or ask your concrete pro about when your concrete is fully cured.

Unfortunately, concrete cracks happen, so there’s no surefire way to avoid them long-term. To slow down the cracking, apply a sealant every two to three years and use sand rather than salt to melt snow or ice. Using salt speeds up the freeze-thaw cycle, which may increase the likelihood of cracking. Additionally, keep vehicles and heavy machinery off of your concrete, as the weight can lead to more cracking.
