New concrete and masonry need to cure for how many days at 75 degrees F before coating?

Explanation:
The main idea is giving new concrete and masonry enough time to fully cure so the surface is strong and dry enough for a coating to adhere properly. At 75°F, thirty days is the typical curing period used to ensure the hydration process largely completes and most moisture has dissipated. Coating too soon can trap moisture and water vapor, leading to poor adhesion, blistering, or peeling. Shorter times leave the substrate damp and weaker, while waiting much longer than necessary isn’t needed at this temperature. So, thirty days at 75°F is the standard ready-for-coating interval.
