Ardex All-Purpose Concrete Resurfacer, Sakrete Flo-Coat Concrete Resurfacer and Quikrete Concrete Resurfacer are three products recommended for resurfacing driveways, walkways and other concrete slabs. All of these concrete resurfacers contain a bonding agent that allows them to attach to the existing concrete without cracking and crumbling after it cures, unlike regular concrete mix.
Before using a concrete resurfacer, do some prep work. Fill all cracks with a concrete repair caulk, and allow the area to cure completely. Also, make sure that the entire driveway is clean and dry to encourage proper adhesion. If the concrete driveway has expansion joints, mask the joints with duct tape.
Next, mix a small batch of the concrete resurfacer in a bucket with a paddle bit. Working in a team of two, apply the concrete resurfacer by pouring it onto the concrete driveway and spreading it with a flat steel trowel while the other person mixes another small batch of concrete resurfacer. Firmly press the concrete resurfacer into cracks and other depressions in the driveway.
After you have resurfaced the entire driveway, use a push broom to lightly texture the surface of the drive to prevent slips. Then, remove the duct tape to expose the concrete expansion joints and allow the concrete resurfacer to cure according to the manufacturer's instructions.
