Concrete first must be scoured clean with a concrete cleaning solution, a scrub brush or a cleaning machine, then allowed to dry before any etching takes place. Never clean a new concrete pad until at least one month of curing time has been allowed at minimum. After all the water has been removed, the pad should have at least 48 hours of drying time before you apply any etching to the surface. If the weather is particularly humid, wait up to 72 hours for best results. There are numerous types of etching materials available for use with concrete, but as a general rule, they only need 15 to 30 minutes of time on the surface of the concrete to work their way down through the initial layer and etch the surface.
Add your answer. How long does it take for cement/concrete to dry? I had a slab leak in my kitchen. A plumber came to my home and had to jack hammer a hole in the floor to get to the leak, after the repair was made he covered up the hole with cement/concrete. How long before we can actually walk on the area? I'm afraid to walk on the area if it is not strong enough, should we wait for 28 days?
