Concrete cures best in temperatures above 50F (10C), so check the forecast for the next week. If you can expect warm temperatures, then now is the right time to pour the concrete. Pouring in the spring or summer is ideal to avoid any unexpected cold weather. If there is a sudden cold snap after pouring the concrete, professionals usually protect the concrete by building a structure around the site and using a portable heater. This is an expensive option, but it's the best choice to protect the concrete. While the concrete is curing, it can't handle excessive weight. Let it dry for a full 24 hours before stepping on it to prevent damage to the surface. If you're water-curing the concrete, take extra care to avoid stepping on it while you re-wet the fabric. If the concrete is in an area with a lot of foot traffic, block the area off and hang signs warning about wet cement. Make sure any pedestrians will know they can't step on the area. Even if the concrete looks dry, it can't handle excessive weight until after it cures completely. If the concrete is in your driveway or a similar area that cars drive on, wait at least 10 days before driving or parking your car on it. If you have a large vehicle like an RV or truck, wait 28 days before parking it on the concrete. Also wait 28 days if this is a commercial area with a lot of vehicle traffic, like a parking lot. The weight from multiple vehicles can cause the concrete to sink. Introducing new chemicals to the concrete before it's completely hardened can interfere with the curing process. Wait a full month before applying any paints or stains to the concrete. If you do want to paint the concrete and used a curing compound, remember to get one that is nonreactive with paint.
Pour concrete when the temperature will be above 50F (10C) for at least 7 days. Wait 24 hours to walk on the concrete. Drive on the concrete only after 10 days have passed. Let the concrete harden for a full month before painting or staining it.
