Concrete Driveway Sealing Guide

Clear the driveway of vehicles and debris. Use a pressure washer to clean the surface fully, removing all dirt, oil, and grease to ensure the sealer bonds properly.

Allow the concrete surface to dry completely. For outdoor projects, ensure there is no rain in the forecast for the week and that temperatures remain between 50 and 90 degrees Fahrenheit.

Prepare cracks and expansion joints. For gaps wider than 1/2 inch, press a foam backer rod into the joint, leaving approximately 1/8 inch of space at the top. Use painter's tape to mask off the edges of the joints for clean lines.

Fill the prepared cracks and joints using a polyurethane concrete crack sealant. Force the sealant deeply into the joint using a caulk gun, ensuring no gaps remain along the edges. Peel away the painter's tape while the sealant is still wet.

Apply the first coat of concrete sealer using a brush, roller, or garden sprayer. Spread the liquid evenly to saturate the concrete without allowing the product to pool.

Apply a second coat of sealer approximately 10 minutes after the first coat, before the first layer has a chance to dry.

Allow the sealer to cure according to the manufacturer's directions. Avoid walking on or parking vehicles on the driveway for at least 24 hours to prevent scuffs or damage.
