How Long Does Concrete Take to Dry? – Posted By: Dynamic Concrete Pumping, Date: Apr 22, 2019 Concrete typically takes 24 to 48 hours to dry enough for you to walk or drive on it. However, concrete drying is a continuous and fluid event, and usually reaches its full effective strength after about 28 days. Here are some of the basic facts regarding the question of concrete drying and curing time.

How Long Does it Take for Concrete to Dry – The general rule of thumb is that concrete takes about 28 days to dry for every inch of slab thickness. Within 24 to 48 hours, the concrete will be ready for foot traffic. However, as we pointed out above, the conditions need to be right.
Should you spray water on new concrete?
WHAT IS THE BEST WAY TO CURE MY NEW CONCRETE SLAB? WHAT IS THE BEST WAY TO CURE MY NEW CONCRETE SLAB? To get the strongest finish out of your new concrete slab for years to come we suggest taking the time to properly cure your new slab for at least 7 days after installation (28 days is ideal). Curing is the process of controlling the rate and extent of moisture loss from concrete during cement hydration.
- Curing plays an important role in strength development and durability of concrete.
- This is done by continuously wetting the exposed surface thereby preventing the loss of moisture from it.
- If water evaporates too quickly, it will weaken the finished product with stresses and cracking.
- To put it simply, the goal is to keep the concrete saturated during the first 28 days.
The first 7 days after installation you should spray the slab with water 5-10 times per day, or as often as possible. Once the concrete is poured the curing process begins immediately. To protect your new slab and ensure an exceptional finished product you should wait 24 hours for foot traffic (including pets), 10 days to drive light vehicles or add furniture, and 28 days for heavy pick-up trucks and RVs.
After 28 days the concrete is cured and you will have a strong and stable slab. After this point you can paint or stain your concrete if you’d like. Properly curing your concrete improves strength, durability, water tightness, and resistance for many years.

Can concrete dry overnight?
At 28 days, concrete reaches its full strength and hydration is complete. – Although the bulk of the hydration process takes place in the hours and days immediately after the pour, concrete needs 28 days to fully dry. While the slab will harden and lighten in color before 28 days, don’t be fooled into thinking it’s done hydrating.
What happens if cement dries too quickly?
All about the moisture – The key thing to remember when curing concrete is moisture. Water causes the mixture to bond and is vital to the chemical reaction that takes place to give concrete its strength. If water evaporates too quickly the concrete’s strength can be compromised and you may end up with cracks.
It is widely accepted that to cure correctly, concrete requires sufficient moisture which can be added in a number of ways. You can spray the surface keeping it consistently damp, cover with a wet material, cover with plastic sheeting or use curing compounds. Which method you use will depend on the weather conditions and whether the surface will be painted or covered once cured.
It is advised not to alternate wetting and drying as this can cause cracking. It is also important to note that too much water in the mixture to begin with can cause problems with the drying process. Too much water can result in shrinkage and reduce the strength of the concrete.
Should you wet concrete as it dries?
DO spray new concrete with water. – One of the most common methods for curing concrete is to hose it down frequently with water—five to 10 times per day, or as often as you can—for the first seven days. Known as “moist curing,” this allows the moisture in the concrete to evaporate slowly.
