Q: I will be pouring a concrete slab as office of a landscaping renovation project and I'd like to know how long it will have for the concrete to dry. Are there any guidelines or precautions I should follow?

A: Sounds like y'all have a fun project ahead of you! Concrete is 1 of the strongest and nigh durable construction materials around, but in guild for it to reach its peak force, it needs to "dry" gradually. This drying process, known every bit hydration, begins the moment yous mix h2o with the dry concrete mix, giving yous limited time to go the moisture concrete into the forms earlier information technology hardens. Hydration continues over the next few weeks, progressing through a number of stages until the physical is completely cured.

During the drying process, stone-difficult crystals develop within the concrete that bind the sand and gravel components firmly together. If the concrete dries as well apace, the finished project won't be as strong every bit it should exist. Read on to find out how much fourth dimension you accept to pour and finish the concrete slab and what you can exercise during each phase to make your projection a success.

Pour time is limited.

With most concrete mixes, such as Quikrete Prepare-To-Utilise Physical Mix (in the xanthous bag) , you tin wait to take almost an hr of work fourth dimension to get the concrete shoveled into the forms, spread out, vibrated, and leveled before the mix begins to harden. During this fourth dimension, it'south vital that anybody who is working on the project knows what their job is and that they work somewhat speedily. Y'all won't have time to run out and buy an actress pocketbook of physical so make sure yous have enough earlier you start the pour, as well as all the necessary tools (shovels, concrete rakes, screed lath, floats, trowels, a broom, an edger, and a groover).

The weather affects work time.

In hot, dry atmospheric condition, especially if you lot're pouring under the blazing sunday, the oestrus can draw water out of moisture physical quickly, reducing pour time to equally petty as 30 minutes, so it's best to pour on a twenty-four hour period when the temperature is between sixty- and eighty-degrees Fahrenheit. If you do have to pour in hot weather, the following tips will help extend pour fourth dimension:

• Employ common cold mixing water.
• Wet downward the sand in the forms before pouring. This will keep the dry ground from drawing water out of the concrete too quickly.
• Shop the bags of concrete in the shade—the hot lord's day volition increase the dry out mix's temperature.
• Schedule the pour during the early on morning when the temps are cooler.
• Recruit plenty of workers because pouring concrete is labor intensive.

Don't forget to factor in finish time.

When pouring concrete, plan to spend one-half of the work time on the pouring process, and the other one-half on the finishing process. If the concrete mix has an approximate one hour of work time (work time is listed on the bag), programme to spend no more than xxx minutes on the bodily pouring and screeding process, so you have acceptable time to end the slab.

To start the finishing procedure, you must screed the surface. Screeding is the process of removing backlog concrete by leveling the top level of the slab. A 2×4 is commonly used to exercise this, but whatever tool y'all apply must be longer than the width of the surface area. To complete the procedure, move the directly edge in a sawing motion across the area to leave it flat. One pass is each direction is commonly enough to achieve the desired result.

Finishing fresh concrete involves floating the surface with a concrete float to smooth information technology out and push button large rocks down, paw-troweling around the edges where the bladder misses, using an edging tool to create rounded edges, adding a broom-terminate texture to reduce slipperiness, and then using a grooving tool to create control joints. The larger the slab is, the longer it will take to finish, so accept that into account and work quickly, and recruit extra help if needed. If the physical begins hardening, skip the control joints and work on smoothing and brushing the surface and smoothing the edges. You lot can always cut the control joints the next day with a physical saw.

Walk-on time depends on the specific type of concrete y'all're using.

With basic concrete mix, you can unremarkably walk on the slab about 24 hours after finishing the surface. If y'all demand to be able to walk on it sooner, you may want to get with a fast-setting blazon of concrete, such as Quikrete Q•Max Pro Concrete Mix that offers a walk-on fourth dimension of just 3 hours.

High-forcefulness mixes tin can come with longer walk-on times, so you'll need to read the particulars on the physical bag. If y'all're pouring an early high-strength mix, such every bit Quikrete 5000, while the work fourth dimension is shorter, nigh 45 minutes, the concrete should not be walked on before x to 12 hours. Considering different mixes differ in work time and walk-on time, it'south important to use only one type of mix in your projection. Don't blend different mixes in the same pour.

Curing will assist the concrete reach its peak strength.

By keeping the new concrete from drying too quickly, you'll accept a stronger slab—and this is where curing comes in. You lot can tedious the drying procedure by spraying the new slab frequently with water for the first seven days to keep it damp.  Known every bit "moist curing," this will help ensure that the moisture deep within the slab is non fatigued to the surface too chop-chop where it tin can evaporate.

Of form, not anybody has the opportunity to spray downwards new concrete multiple times during the first week to keep information technology clammy. If this applies to you, no worries. Y'all tin can apply a curing product, such as Quikrete Acrylic Concrete Cure & Seal, to the surface of simply-finished concrete in gild to keep the water within from evaporating and causing the concrete to dry likewise quickly. Acrylic Cure & Seal tin can be applied to the surface of the slab with a roller or garden sprayer just as soon as the concrete hardens and the surface sheen disappears.

After vii days from pouring the concrete, you tin drive on a new driveway.

By the time a week has passed the physical volition take reached approximately 90 percent of its final strength, and information technology'south commonly safe to drive on information technology. If y'all have a large size vehicle, however, such equally a 1-ton pickup truck, it's a proficient idea to wait a few days or even a week longer.

At 28 days, concrete reaches its full force and hydration is complete.

Although the bulk of the hydration process takes identify in the hours and days immediately afterwards the pour, concrete needs 28 days to fully dry. While the slab volition harden and lighten in color earlier 28 days, don't be fooled into thinking it's washed hydrating. If you programme to stain or paint the physical, doing so before the process is complete can result in changes in the stain color or the paint peeling off.
