Whether you recently installed a new driveway or you’re repairing it soon, you’re likely already thinking about how to preserve your investment. Though it looks solid, concrete is porous and will absorb water. When the temperature drops, the water will freeze and expand, causing cracks. It’s imperative to seal the concrete to prevent this. If you’ve never sealed a driveway before, here is what you need to do to keep your investment looking like new. 

How to Seal a Concrete Driveway

1. Choose Your Sealer

There are several different types of sealers available, so it’s important to make sure you choose the right one before you start. A few options are acrylic, epoxy, and penetrating. Some epoxy and resin sealers will offer a higher gloss level than others for those who want a shine. Those with stamped or colored concrete may appreciate the shine from a high gloss sealer. For those who want a more natural look, a matte finish is the best option. 

2. Prepare the Surface 

Before applying the sealer, the surface needs to be clean of dirt and debris. Sweep to remove dirt and leaves and use a pressure washer to remove oil or grease stains. Allow 24 hours for the driveway to completely dry before applying the sealer to avoid trapping in any moisture. 

3. Apply the Sealer

Sprayers, rollers, or brushes can all be used to seal your driveway. Sprayers will give even coverage with less work. A garden sprayer won’t work for this job, so consider purchasing or borrowing a contractor grade metal sprayer for the job. If you notice any areas of pooling, use a brush or sponge to smooth them out. Make sure to wear gloves, glasses, and a mask to avoid coming into contact with the chemicals. Once you’re finished, allow at least 24 hours for the sealer to dry before walking on it. 

4. Perform Maintenance

Every few months, wash the driveway to remove debris and mud. Areas where the sealer may be thinning can be touched up with a brush. The surface will need to be resealed every 1 to 3 years depending on wear and weather.
