How Long Should Concrete Cure?

DIY Questions and Answer March 19, 2008 Chad



Q: I’m about to pour a new sidewalk. How long should I let the new concrete cure before walking on it?

A: Generally speaking, concrete and other Portland cement-based products should be moist-cured for at least 5 to 7 days. Check the product packaging for specific instructions. One alternative to moist-curing is using an Acrylic Concrete Sealer. Applied at the appropriate time, this will help the concrete cure properly while sealing it against stains that tend to penetrate the surface of the concrete. Note: An acrylic concrete sealer should not be used in temperatures below 50 degrees F or when rain is expected within a few hours.
