Planning A New Concrete Driveway? Learn How To Seal It

Posted on

If you are planning to install a new concrete driveway, you should make sure you put a sealant on it when it is finished. There are many benefits of doing this. The sealant can protect your driveway from things like oil spills and other stains, cracking, and flaking. It also improves the appearance of your driveway, which adds to the curb appeal of your home. Below are the steps you need to take to seal your driveway so you will be ready after it is poured.

Let the Concrete Cure

Make sure you let the concrete completely cure before you start sealing it. If you apply the sealant too early, it will bubble and crack on the concrete. A service, like Van Doren Red-E-Mix, can tell you how long to wait. In many cases, this can be up to a week, depending on how thick the driveway is and the weather conditions of when it was poured. When you are ready to apply the sealant, make sure you choose a day with warm weather.

Sweep the Driveway

Once the concrete has cured, sweep your new driveway using a push broom to remove all debris and dirt before you seal it. If there is already oil or grease spilled on the driveway, you can use a power washer to remove it. Purchase a concrete degreaser and put it into the detergent bottle on the power washer. Spray the stains and let the degreaser sit on them for a few minutes. This will give the cleaner time to penetrate the stains. After this time, put plain hot water in the bottle and spray the area over again to remove all cleaner. Let the driveway completely dry.

Apply the Sealant

You can purchase the sealant at just about any home improvement store. While you are there, purchase a backpack or hand sprayer to make it easier to apply; otherwise, you will need to use a long-handled plastic squeegee to spread the sealer. Spray the sealant on the driveway in an even coat, making sure you overlap previous sections' borders to eliminate potential gaps, and let it completely dry. It is easier to start at one end and move your way down spraying across the driveway as you go.

Look at the instructions that come with the sealant that you purchased for drying times. This is likely a few hours. To make sure it is sealed after the allotted time, touch the surface with your finger.  If it feels sticky then it is not dried completely. You should apply a second coat when the first coat is dry for added protection.

If you do not feel comfortable sealing your driveway yourself, ask your concrete contractor if they can do this for you. They can also give you many other tips on keeping your new driveway in good condition.
